Story of the Week...

COP 22 Banner

Fears that U.S. President-elect Donald Trump will pull out of the 2015 Paris Agreement to limit global warming pushed almost 200 nations at climate talks in Morocco on Thursday to declare action an "urgent duty".

Trump has called man-made global warming a hoax and has said he will withdraw from the Paris Agreement, which seeks to wean the global economy off fossil fuels this century with a shift to renewable energies such as wind and solar power.

In a statement, the ministers at the meeting said momentum for cutting greenhouse gases was "irreversible" and reaffirmed their commitment to "full implementation" of the Paris accord.

"We call for the highest political commitment to combat climate change, as a matter of urgent priority," they said in the Marrakesh Action Proclamation.

"Our climate is warming at an alarming and unprecedented rate and we have an urgent duty to respond," it said. Delegates applauded and joined hands above their heads in a standing ovation after the proclamation was read out.

La Niña Update...

According to the latest forecasts, 2016/17 should be stamped in history as an official La Niña season. And although its relative weakness has somewhat downplayed its existence, La Niña is already halfway through its run.

La Niña is the cool phase of the El Niño-Southern Oscillation, which is very closely monitored by commodity markets as ENSO is one of the most reliable long-term indicators of weather patterns on the global scale.

In its monthly ENSO discussion last week, the U.S. Climate Prediction Center issued a "La Niña Advisory," its first official recognition of the phenomenon’s presence. The agency left the probability for weak La Niña to persist through the Northern Hemispheric winter months unchanged at 55 percent.

Quote of the Week...

Now we know that many other industries have learned from Big Tobacco’s playbook. Physicians hired by the National Football League have questioned the evidence that concussions can cause brain disease, and soda sellers have financed research to deny that sugar causes obesity. And climate deniers have conducted a kind of scavenger hunt for oddities that appear to challenge the overwhelming consensus of climate scientists.

SkS Spotlights...

The PRISM Climate Group gathers climate observations from a wide range of monitoring networks, applies sophisticated quality control measures, and develops spatial climate datasets to reveal short- and long-term climate patterns. The resulting datasets incorporate a variety of modeling techniques and are available at multiple spatial/temporal resolutions, covering the period from 1895 to the present. Whenever possible, we offer these datasets to the public, either free of charge or for a fee (depending on dataset size/complexity and funding available for the activity).

Video of the Week...

Delegates from more than 190 countries have met in Marrakech, Morroco this year at the UN Summit, COP22 to granularly discuss and apply the Paris Agreement on climate change which was hammered out last year.

The COP stands for the “Conference of the Parties.” It is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC), opened for signature in 1992 during the Earth Summit in Rio de Janeiro and later entered into force in 1994.

The ZME Science team was at the event for two weeks and shared loads of news and impressions about the discussions and activities that took place at the summit.

97 Hours: Rob Dunbar 


Rob Dunbar's bio page

Quote derived with permission from author from:

"So here's the thing. It sounds like a simple question. Is CO2 produced by man's activities causing the planet to warm up? But to answer that question, to make a clear attribution to carbon dioxide, you have to know something about all of these other agents of change. But the fact is we do know a lot about all of those things. You know, thousands of scientists have been working on understanding all of these man-made causes and the natural causes. And we've got it worked out, and we can say, "Yes, CO2 is causing the planet to warm up now."

  1. If there is global warming then CO2 is not the cause.

    Go and look elsewhere.

  2. Every 2500 molecules in the air has only one CO2 molecule.

    And you think it will make a change. Hoax.

    [JH] Sloganeering snipped.

    [PS] This discussion belongs on "CO2 is just a trace gas" myth. I wonder if Plato would enter a room with only 1 in 2500 molecules being HCN?

  3. plato525 @1 and @2 shows all the commitment to clear reasoning we have come to expect from AGW deniers /sarc.

    With regard to his post @2, taking a different angle - Iron represents 670 ppmv of the human body.  By plato525's implicity reasoning, changes in its proportion in the human body can make no difference.  Much of that iron, however, is found in various globulins, of which the best known is haemoglobin.  Without iron, there is no haemoglobin, and hence no transport of oxygen from the lungs to the muscles.  Without iron in the body, that is, we would suffocate in seconds.

    Of course, with too much iron (50 ppm by mass) in your dietary intake will result in severe iron poisoning.  If sustained, it will you will suffer acute pain as you vomit blood more or less continuously untill you eventually die of kidney failure.

    This is just one more example among thousands in which plato525's "reasoning" simply fails.  In fact, the counterexamples to his claim are so numerous, and so well known that his claim is not entitled to the claim of reasoning.  It is, most likely, empty rhetoric; and quite possibly a belief siezed on desperately to avoid thinking clearing on the topic.

  4. Tom Curtis @3,

    You may not recall plato525's previous visit to SkS a three months back in which the "video experiment with the black color solution that was added to water in a glass container to show the amount of CO2" was sought. It appears plato525 found the demonstration unconvincing.

    And as plato525 is not what you'd call chatty, establishing why he remains unconvinced, or indeed the reasons for his apparent doubt on there being rising global temperatures @1 or his branding AGW as "hoax" @2; all this may remain unresolved.
