    Semantics again. I use the dictionary definition of "radical" to mean "fundamental". Others use radical to mean "wild eyed whacko" or something similar. Some of us environmentalists strive to deal with the fundamental life services of the environment. We adhere to the notion that the environment is not easily manipulated by humans...that we should adapt to the "natural" environment in which we find ourselves, like other animals do, and stop altering "nature".

    As to cats and dogs. There are 63 million of these critters in the US alone. A reduction of at least 62 million would be a prudent aid to environmental wellbeing.

  2. Solar and crop production research shows ‘multi-solving’ climate benefits

    Perhaps it is my use of the term: nutritional value. While protein can be called a nutrient because it is used by the body to build muscle structures, human bodies need fats for energy production. Lipids are 1 of 6 essential components in animal life forms and are essential in an every-day diet. Protein is needed, of course, but in infrequent amounts. Animal organisms can do without protein for extended periods (like starving prisoners of war) but fat intake is a daily dietary need for humans.

  3. Solar and crop production research shows ‘multi-solving’ climate benefits

    Go to literature not published by commercial agricultural interests. Rabbit meat is all protein. Routine periodic consumption of this animal causes protein poisoning which can and eventually will kill you. In regions of the world where food options are scarce, rabbit is a consumption item because it is plentiful since rabbits breed like rabbits (humor intended). Nutritionists in First World countries do not recommend eating rabbit because they provide no fat, which is required in the human diet. Rats are rodents, of course, as are rabbits. We should not eat rats either, for much the same reason: protein poisoning.

    scaddenp,

    I wasn't comprehensive or specific enough in my earlier responses.

    There is probably a lack of research findings regarding bird kills by off-shore wind turbines because the evidence quickly disappears and there are very few observers of the turbines seeing it happen. It would probably take some serious government interest and investment to set up a rigorous methodology for doing the research into that issue.

    This is something that would potentially be researched if there are declines in bird populations that are serious enough to attact significant global government research funding (like so many other harmful developments, investigate after it is too late). However, the on-shore evidence and understanding of bird kills should be expected to extend to off-shore locations where the evidence almost immediately disappears.

    scaddenp,

    More specifics regarding the negative impacts of off-shore wind turbine installations may not be avaialable because the industry promoting and building them is affected by the legacy of the developed economic game that encourages evasion of rigorous investigation of potential harm.

    Government money should be flooding into better understand the potential harm of all new approved developments and all the already developed stuff. But that is not popular or profitable.

    There are very few instances of sustained government leadership that has acted in helpful, but economically unpopular and unprofitable, ways. That explains any lack of investigation and reporting of harm and potential harm. There will likley be a lot learned about the harm done by the most popular and most profitable (lowest cost) actions attempting to address the climate change problem, not just the later learning of negative impacts of off-shore wind turbines.

    scaddenp,

    Regarding bird kills, the book "Rebuilding Earth" makes reference to the September 6, 2014 article in The Treehugger by Michael Graham Richard, with the most recent update of the article (Oct 23, 2020) here

    nigelj @8,

    Turbines over water immediately adjacent to the consumers they power would work, provided that bird migration patterns and marine impacts are avoided. More remote power generation to overcome the delivery losses from remote power generation produces more impact, unless it is done to avoid marine and avian (or any other negative) impacts.

    Having to do more or pay more to avoid harmful impacts is "correct economics". Moving a harmful problem away from human sense or thought, by distance or into the future, is simply unethical no matter how much more popular or profitable that may appear to be.

    scaddenp,

    Many sources address the bird kills by talll buildings.

    This CNN report is only one of many on the subject.

    The major concern is buildings lit up at night. But, as mentioned in the article, daytime bird strikes can also happen because of reflective glass covering a building or plants next to windows fooling the birds.

  9. 2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    OPOF fair points, but putting wind turbines offshore might still be better overall, where its practically feasible from an electricity supply perspective. Its likely going to reduce bird strike problems, and would  definitely reduce insect strike problems, and does virtually eliminate the visual problem. Offshore wind farms do not seem to have too many negative impacts on ocean ecosystems. Refer:

  10. 2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    Does the book cite research to back the problem of tall structures on bird routes? Can you give me the cites please? I would say outright that it is over-generalization and certainly doesnt bother all species.

    This 2021 literature review doesnt seem to find any insurmountable problems but does emphasize the importance of planning and mitigation.

  11. Solar and crop production research shows ‘multi-solving’ climate benefits

    Swampfox could you please provide proof of your assertion that rabbit meat contains low nutritional value for humans, because 1) it defies basic commonsense and 2) a quick google search shows a vast quantity of credible publications stating rabbit meat has a particularly high nutritional value for humans. The first three hits are below:

    nigelj,

    Teresa Coady's book I referred to also points out that tall structures along any migratory bird route is a problem, even off-shore. In addition, marine impacts of off-shore human developments also need proper consideration. Otherwise, putting wind turbines off-shore is just another harmful development akin to "moving coal power plants out of the city" which is the UnSolution of "Problem moved away - perhaps even being more harmful but out of sight so Okay?"

    2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    nigelj,

    The term "radical environmentalist" is problematic. It can mean anything. I would support the "radical environmentalists" being the ones deciding what happens if they are "radical" by including "Social" considerations in their pursuit of increased awareness and improved understanding of what is going on and the application of their learning to pursue the end of social and environmental harm done by human developments and make amends for harms that have already been caused.

    I agree that people should be concerned about the harmful impacts of human development, including harm done to birds.

    But the focus of that bird concern deserves to be on buildings that are more than, say, 6 stories tall. There are plenty of easy to access resources explaining that tall buildings kill lots of birds, especially the glass covered ones, especially if they have inside lights on at night. It is likely that a tall building kills more birds than an equally tall wind turbine. So it may be that it would be less harmful for tall buildings to be replaced by 6 storey buildings with wind turbines above them (and the total harmful impacts of building and operating shorter buildings would also be less than the impacts of the tall buildings - "Rebuilding Earth" by Canadian Architect Teresa Coady, is the most recent item I have read that includes this type of information as part of the understanding of how to address the climate change problem and many other problems caused by human development).

    But the biggest killers of birds are domesticated cats. And that relates to a "population problem of concern" than can and should be acted on - Reducing the harm of pet over-population. Some domesticated animals are helpful. But many pets cause harm and increase demand for resources. Reducing the harmful impacts and consumption caused by unnecessary Pets could be a helpful step while the human population problem is brought under control by the continued pursuit of the Sustainable Development Goals through the next 40 to 50 years (peak global population may occur in the 2060s).

    But even if the human population problem is controlled, the problem of harmful over-consumption by the highest consuming and most harmful portion of the population could persist, even becoming a bigger problem as the total global population declines.

    So the real problem/solution is reducing the harmful over-consumption that some humans have developed a liking for. Free choice to believe and do whatever a person wants is not a solution. It is a problem. Reduced the energy demand will reduce the amount of harm done by "required" power generation systems like wind turbines.

    The wealthiest are the ones who can afford to live the lowest energy consumption lifestyle. The required global fundamental understanding needs to be that the wealthiest and most powerful should be required to prove they deserve to be wealthier and more powerful by living with less benefit from harmful actions than those who are less fortunate. Wealthier or more powerful people should not be Freer to Choose to be more harmful, even if they can afford it or abuse their power and influence to get away with it.

    That "Winning by harmful pursuers of status" is an Age Old Problem. But problems can only be solved by increased awareness of the actual fundamental problem.

    Radical environmentalists could be the solution, depending on what type of person that term actually refers to.

  14. Solar and crop production research shows ‘multi-solving’ climate benefits

    I wasn't sure where to start with the above essay, so much of it is grasping for straws. 0.6% of the land necessary to erect solar power grids, then employed for the reasons listed, is itself a discussion about nothing at all. We would be better off just planting trees on an equivalent area on the other side of town, or converting cattle grazing land to riparian. As far as raising rabbit goes, current nutritional science has proven that eating rabbit is equivalent to eating rats, insofar as nutrient values are concerned. There are no nutrient values in rabbit meat...not for humans. Regarding bee habits, we beekeepers know that bees enjoy sunshine and love the floodplain of rivers as forage areas, although they will harvest the nectar of flowering trees, especially tulipfera species which cannot grow under a solar panel. My apologies, I could go on about several other points made in this post, but my essay is long enough as it is. ...someone else's turn.

  15. 2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    Don't let radical environmentalists decide what electricity generation gets built, because nothing would get built. Solar power looks relatively benign environmentally. Wind turbines are more problematic because of the big visual footprint on hills that some people dont like, and they kill insects and some birds, lets not pretend otherwise. The solution is really to locate them offshore, something central governmnet should require by law, maybe 50% offshore and gradually increased from there.

    Book Review: Saving Us by Katharine Hayhoe

    UniteHumankind @6,

    I understand the intention, but yes, it is very silly. To have any validity, a poll must be taken on a representative sample. Many precautions enter in the rather complex selection process that allows for a representative sample. In your case, not only that is not the case, but you are even down to attempt overcoming a manipulation of the poll with a counter-manipulation maneuver. What validity can the poll have? Close enough to zero to be negligible.

  17. 2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    It would be best if radical environmentalists had the final say on site selection, since they have no monetary or political axe to grind. We are happy with eliminating as much fossil fuel usage as possible, but not happy with collateral damage to the environment from insensitive projects.

  18. 2021 SkS Weekly Climate Change & Global Warming News Roundup #49

    We should not lose sight of appropriateness in site selection...and we are. In the rush to renewables, many proposed sites are moneymakers but are deleterious to the environment. Here in Rockbridge/Bottetot County, a wind turbine site proposal has 100% opposition from area radical environmentalists.

    Can genetically engineered seeds prevent a climate-driven food crisis?

    John Hartz @2,

    Thanks for pointing out the article.

    It is an interesting perspective on the well established understanding that has been written about in different ways by many different people in recent years. It alings with the understanding shared by Gaya Herrington after she revisited, and performed an update on, the "The Limits to Growth" study published by the Club of Rome in 1972 (one article about this is The Guardian reporting on her study).

    An important understanding is that Over-population is not the real problem. And the population problem is undeniably being more effectively addressed than the climate change problem.

    The real problem is harmful over-consumptive ways of living that some humans have developed a liking for. And those harmful over-consumers provide harmful unsustainable examples that others can be tempted to aspire to develop to match or exceed.

    There are many sources of information to help people improve their understanding that Total Population is being address and that the harmful over-consumption problem fails to be effectively addressed. People who claim to be concerned just need to act on that concern and become better educated. But it is undeniably difficult to get people to learn something that contradicts their developed preferences or that contradicts something they want to claim to excuse not understanding the real problem. Proof of that difficulty is the lack of effective actions to limit harmful over-consumptive ways of living like the ways of living that cause the growing climate change problem and people continuing to claim that "over-population is the problem".

    The Guardian has an article that says the International Energy Agency, IEA, projects that 95% of new electricity generating capacity worldwide from today to 2026 will be renewable energy.  

    Renewable energy is being built out because it is now cheaper than fossil fuels almost everywhere.  This winter coal, gas and oil have increased greatly in price while renewable energy has only increased a little.  Hopefully businesses will increase installation of renewable energy to save money.  It will help with the climate issue.  Every kilowatt generated by renewables is less generated by fossil fuels.

    Another article stated that one of the primary bottlenecks for wind energy was obtaining permits to build.  Governments can speed up the permitting process to increase renewable energy.

  25. Gerrymandering is a climate problem

    Swampfox. Your assertions are simply not correct. Numerous polling studies (eg Pew Research) find huge difference on climate issues between republicans and democrats, where republicans are generally more sceptical than democrats about the science, carbon taxes, and wind and solar power (although the gap is smaller for wind and solar power). A simple google search found Democrats far more likely to buy EVs than Republicans. It shouldn't be like this, but it is like this.

    Thanksgiving advice, 2021: How to deal with climate change-denying Uncle Pete

    Unfortunately, there isn't so much information in this post as there is social reinforcement--it goes back to the old trope of the crazy uncle and serves to encourage thinking the other side is stupid.

    I also notice that certain supporting information like that the pentagon takes climeat science seriously neglects to mention that all, that is all, of their predictions about climate were wrong. The Climate Discussion Nexus offers a lot of actual, real information without so much "snide." This one is about the Pentagon predictions:

    https://www.youtube.com/watch?v=yj83l0mcWUY

    We should be focused on the actual pace of change and its effects as well as what to do about it, not scoring points on who was right or wrong all along. This video needs to be posted so it's clear this article is not a font of scientific accuracy, but what we need to do is focus on reasonable action.

    This article fails in that way and can only serve as candy for true believers.

    Gerrymandering is a climate problem

    Swampfoxh,

    It is possible to understand that "What is needed is not support of a political constituency, rather the declarations and positive actions of dictators who, from scientists, know what has to be done." is a misled belief.

    Any type of leadership will work. The commonsense requirements is that the leadership (winners) all pursue increased awareness and improved understanding of what is harmful and aggressively act to rapidly end the harmful activity in "the least harmful way", with the political differences being different perspectives that create a diversity of effective ways to rapidly end the harm being done. An important understanding is that "perceptions of harm done by the ending of harmful activity" need to be restricted to concerns to ensure that everybody live at least a basic decent life - No Poverty. It is important to understand that it is not harmful for supposedly superior people to become less superior because harmful activity they benefited from is ended.

    The key is to end the nonsense belief that any developed perceptions of prosperity deserve to be maintained as the harmful activity is ended. That legacy argument that excuses incredibly harmful things like oil extraction in California to continue because it "was initially permitted and therefore is grandfathered into being allowed to continue" has to be scrubbed from the system.

    Sustainable activity by all of humanity is the only starting point that can be constantly continued or improved on by the development of better "also sustainable harmless" alternatives. Humanity has millions of years to enjoy this planet, so the accumulated impact of actions of each generation have to be essentially harmless.

    The challenge of today is "getting to the starting point of all of humanity living sustainably, all people living decently, no harmful poverty". That means everyone learning and pursuing living in ways that are not harmful to others or the environment of the planet that is essential to all future life on this planet (a key point being the understanding that technology can be helpful, but is not essential to life). And the "wealthy and powerful" need to be required to be leaders of the correction of what has developed. The alternatives to that responsible leadership are ultimately disastrous for humanity.

    The problem is the small portion of humanity who develop a liking for benefiting from being harmful. That small group have been in control of much of humanity since the earliest days. The evidence is growing that the growth of that type of "controlling people" has always been a harmful growing problem. It has now grown past the point of being able to be ignored or excused. And a growing number of people are realizing that ... including the gerrymandering types using their powers to prolong their ability to be harmful Winners who are just like the harmful dictators and populist pursuers of power.

    Something has to be done. Hopefully it will be the Winning by responsible thoughtful people. The alternative is a growing disaster in the making. (btw, the likes of Trump owning a Tesla as one of their personal vehicles obviously does not represent their overall actions and impacts).

  28. Gerrymandering is a climate problem

    There is clearly no connection between sensible, practical and necessary methods to remedy human behavior in seeking solutions to climate and environmental problems, based on political affiliation or the assumed leverage of a majority constituency. People and groups working proactively on climate are doing so with no regard to their own political party affiliations. If Democrats were really better at this work than Republicans, progress would be significant because the Yale study back in 2012 showed that more people identifying as Democrats were delivering support to reducing fossil fuel consumption, but it's Republicans whom are buying the electric cars. What is needed is not support of a political constituency, rather the declarations and positive actions of dictators who, from scientists, know what has to be done. Consequently, nothing will be done. Humans are an outlaw species on planet Earth and will just have to try and pick up the pieces after the coming extinction event runs its course.

    Climate-conscious conservatives try to make their voices heard

    swampfoxh,

    I have a different perspective regarding current politics.

    The real problem has little to do with political identity. It has a lot to do with the "identities being developed by political groups".

    My two categories to put people into are:

    1. People willing to increase their awareness and understanding of what is going on and learn what is harmful and how they can be less harmful and more helpful to others, including their impacts on the environment beyond their "socioeconomic political environment of the moment".

    2. People who have developed beliefs that they desire to protect against the changes that could come from increased awareness and improved understanding of what is "harmful to the future of humanity" and how to be less harmful and more helpful.

    There could be a third category of people who are simply unaware. But every member of that group that gets introduced to new thoughts becomes either Group 1 or Group 2 based on their response at that moment. Do they pursue learning to be less harmful and more helpful or resist it?

    People who enjoy perceptions of superiority relative to others, and people who want to be "superior" like them, can be understood to be highly motivated to resist learning in the current socioeconomic political environment that has developed a lot of perceptions of superiority built on harmful unsustainable actions.

    The lack of interest in learning that the ways a person obtains benefit and perceptions of superiority are unacceptable, especially if it is learned that their ancestors developed the "life style they were born into" through harmful actions meaning that they owe a debt of "systemic change and other compensation" to many of those Others who they consider to be "deserving to be less superior". That is almost an eternal human problem, the victors making up harmfully unjustified justifications for their developed perceptions of Superiority relative to Other people (or other life).

  32. Can genetically engineered seeds prevent a climate-driven food crisis?

    Perhaps this website could do an article on population related to the climate issue and other environmetal issues. However I suggest we know what the viable solutions are: Namely  better education, better womens rights, the demographic transition, contraception etc. Most countries are addressing those sorts of things. Some are not doing this so much, often due to religious factors,  and short of preaching about it its not clear what more we can do. They are sovereign nations. Its why I think we have to mostly promote renewables and lower consumption etc.

  33. Climate-conscious conservatives try to make their voices heard

    Swampfox @1 & 2. You are right about that. Generally the way systems work in western democracies is you get a progessive reforming governmnet doing its thing for a few years and then a conservative governments gets elected, then back to a progressive governmnet in a cycle. And generally the conservative leaning governments have kept in place many of the progressive reforms, maybe cancelled some of the crazier ones. Its kind of worked ok. You had a consensus between conservatives and progessives over plenty of the important things,

    Occasionally you get a governmnet with an excellent balance of reform and restriant but that seems to be rare. Its more often a cyclcial progression of left and right leaning governmnets.

    IMHO the problem is in recent years newly elected conservative governmnets have been cancelling every policy of progressive governments they possibly can, and often it seems just out of spite and hatred. Theres often very little logic to what they do. Its become extremely tribal in America. I dont know how that gets fixed. Biden is trying but also faltering. 

  34. Climate-conscious conservatives try to make their voices heard

    Democrats, on the other hand, are revisionists.  They see improvement is always possible.  It is often said that Democrats might maintain a point of view reflected in the lyric in Johnny Cash's "Man in Black","...that things will never be right, I know...". Progressives are a group of generic Democrats that have named themselves "Progressives", and are often willing to make changes in most social, economic and political (even religious) systems with no special regard for the suitability of those changes...or even the need for change at all.  

    Between the two groups, the Republicans and the Democrats?  The trick might be to find a way to satisfy the "longing to change things with the longing to leave things the way they are."   But, finding that trick?  I've not the slighest idea.

  35. Climate-conscious conservatives try to make their voices heard

    Republicans shun the climate problem because they resist collectivist action. At bottom, Republicans believe "Man is and end in himself, not a means to the ends of others". Any human action that smacks of collectivism, like socialism, communism or fascism will always be rejected by people who identify as Republicans (generally). Republicans and their "individualism" can participate in fixing the climate problem if they don't feel like they are going to be swept away to a government gulag by Marxist/collectivist style coercion. People who identify as Democrats are always ready to manipulate the social fabric, whether it needs fixing or not. Republicans fear change. That's why there are often called Conservatives.

  36. Can genetically engineered seeds prevent a climate-driven food crisis?

    swampfox: I couldn't agree more.

    Comment on overpopulation brings forth instant abuse on most comments' columns - usually snidely asking whether the writer should be the first to drink the koolaid. ie. punishing the messenger.

    But it's hard to fathom why it appears taboo across the board when its OBVIOUSLY the fundamental problem.

    Not saying there's a solution apart from war, famine, flood and drought. Most of these are well under way without any deliberate "solutions".

    You can feel it.

  39. How much has nuclear testing contributed to global warming?

    The contribution of nuclear testing to global warming should be analyzed not by the total energy released by nuclear explosions wich is of course negligible over the earth surface but rather by the impact of radioactive radiation lasting for decades in the strata especially in the ozone layer wich has a very destructive and complex effect. Please see new study here:

    According to a recent chat on this site, 80 million more people were added to the planet in the past 365 days. Thus, yesterday, 218,800 more new people are walking the Earth, than on the day before yesterday... and another 218,800 will be added today. Not only are these carbon footprints being added to the GGE problem but each of these are consumption and destruction machines acting against a variety of ecological benefits (clean water, reforestation, carbon sequestration, AMOCs, LUCs, cryosphere change,  etc.) Who will come forth to author an expansive essay, similar to the one above, that will remedy the population of humans problem and do so as comprehensively as the above essay has for seeds?

    Nigel - Ha! Yes, believe me, it is very frustrating for me when there's an Uncle Pete around. I did enjoy reading your post! Thank you. 

  43. Thanksgiving advice, 2021: How to deal with climate change-denying Uncle Pete

    Robin, I agree there is no point ruining a family gathering by debating climate change with Uncle Pete, and its best to change the subject. Although I find it takes me an effort of will to do this. I was silently thinking stick a sock in his mouth and sit him in a corner of the room and shove a bottle of whisky in his hand to keep him amused. I know we cant really do this but it was an interesting, satisfying thought.

    However what do we do when uncle Pete appears on websites like this? This is more perplexing because he (or she) can sway impressionable people following the discussion that are mildly sceptical. There seems to be a school of thought that says ignore Uncle Petes when they rear their ugly heads in public forums. Engaging with them draws attention to them so its thought. Pretend they don't exist. In my observation climate scientists have mostly done this (this website excepted) but this strategy has obviously not stopped Uncle Pete causing havoc.

    Personally I think its better to rebut their claims but without getting too much into an extended one on one debate. If possible dont even use their name. You are really not trying to convince or inform Uncle Pete, but other people involved in the discussion or reading it.

    Some people directly engage Uncle Pete partly just to ridicule them and for entertainment. I confess I've sometimes done this myself. But this is a risky strategy because it can alienate people who dont like such harsh treatment and stong language.

    Uncle Petes are very frustrating. I wish they would just  STFU.

  45. Thanksgiving advice, 2021: How to deal with climate change-denying Uncle Pete

    This article has great information but as far as Uncle Pete goes, smile, nod, and quickly change the topic. According to the Yale program on Climate Communicatio, only 8% of Americans are "Uncle Petes". Nothing can change their mind so save yourself the frustration and keep your gathering pleasant.

    Instead be thankful for the 92% of people you can work with to learn about climate change and get going on implementing solutions.  

    Here's a quote from an editorial in my local paper, The Dai Inter Lake, published today (Thanksgiving 2021):

    "When we say our blessings at Thanksgiving dinner this year, may our thoughts be for the greater good and our words be carefully parsed for a community and, for that matter, a world that so desperately needs our love, and may the gratitude in our hearts shine toward finding solutions … and being part of them."

    Happy Thanksgiving!

  46. Global CO2 emissions have been flat for a decade, new data reveals

    pattimer @1,

    The Global Carbon Project correction to FF+LUC anthropogenic CO2 emissions over the last decade is actually very minor. I compared the before-&-after numbers when first published and for that period (from memory) OLS showed they changed from +75Mt(C)/yr to +25Mt(C)/yr. (The increase in emissions had been running at about +200Mt/yr through the preceding two decades.) So an already quite-flat emissions rate through the last decade is revised somewhat more flat. Given the wobbles in the draw-down of emissions our into the biosphere, the calculation of Af is a long-term thing. (It averages 44.3% 1959-2020 with a 2sd variation of +/-25.9%.) So the impact of the adjustment on Af is insignificant. For 2019 the single year figure previously 48.7% becomes 49.1%.

    Af will get interesting when we get round to reducing our collective CO2 emissions. The draw-down of CO2 is not a single-year-emissions thing as suggested by the Af but the draw-down of our accumulated CO2 emissions over the decades (& eventually centuries). Thus the 2.99Gt(C) ocean draw-down and 2.92Gt(C) biosphere draw-down estimated by GCP for 2020 would hardily have budged if we had halved emissions in 2020. But if emissions had halved from 10.38Gt(C) to to 5.19Gt(C), the atmospheric levels would have dropped and Af would have turned negative.

  47. Global CO2 emissions have been flat for a decade, new data reveals

    Ian, the atmospheric fraction of CO2 remaining after sinks do their thing has held steady at 45% for a very long time.  See Friedlingstein et al 2021 for details.

  48. Global CO2 emissions have been flat for a decade, new data reveals

    I had been thinking the same thing. Using data from wood for trees the rise in CO2 during the period 2000 to 2010 is 2.04 ppm /year. The rise from 2010 to present is 2.45 ppm /year, an increase of 20%. Why the discrepancy with the data on CO2 released from burning of fossil fuels?

    There are a number of possible reasons. Firstly, the countries may be fudging their CO2 figures. Secondly, another source of CO2 is becoming significant e.g. CO2 from forest fires or melting permafrost. Thirdly, sinks are losing their effectiveness in removing CO2 from the atmosphere.

    Any comments?

  49. Global CO2 emissions have been flat for a decade, new data reveals

    Interesting article. And hello everyone at Skeptical Science. It's been a long time since I have been in touch. 

    However 

    I have a question. 

    If CO2 emissions have been less than previously thought in the past from fossil fuels and land emissions but the atmospheric CO2 is increasing just precisely as we measure it then does this not mean that very worryingly the air borne fraction must be increasing. If so positive carbon feedbacks are coming earlier than we feared? OR Have I missed something? 

  50. Do COP26 promises keep global warming below 2C?

    Climate Pledges Still Not Enough to Keep Warming Below 2-Degree Limit

    Current national targets to cut emissions could result in nearly 3 degrees C of warming
