2023 SkS Weekly Climate Change & Global Warming News Roundup #41

Posted on 14 October 2023 by John Hartz

A chronological listing of news and opinion articles posted on the Skeptical Science Facebook Page during the past week: Sun, Oct 8, 2023 thru Sat, Oct 14, 2023.

Story of the Week

I Study Climate Change. The Data Is Telling Us Something New.

Staggering. Unnerving. Mind-boggling. Absolutely gobsmackingly bananas.

As global temperatures shattered records and reached dangerous new highs over and over the past few months, my climate scientist colleagues and I have just about run out of adjectives to describe what we have seen. Data from Berkeley Earth released on Wednesday shows that September was an astounding 0.5 degree Celsius (almost a full degree Fahrenheit) hotter than the prior record, and July and August were around 0.3 degree Celsius (0.5 degree Fahrenheit) hotter. 2023 is almost certain to be the hottest year since reliable global records began in the mid-1800s and probably for the past 2,000 years (and well before that).

While natural weather patterns, including a growing El Niño event, are playing an important role, the record global temperatures we have experienced this year could not have occurred without the approximately 1.3 degrees Celsius (2.3 degrees Fahrenheit) of warming to date from human sources of carbon dioxide and other greenhouse gas emissions. And while many experts have been cautious about acknowledging it, there is increasing evidence that global warming has accelerated over the past 15 years rather than continued at a gradual, steady pace. That acceleration means that the effects of climate change we are already seeing — extreme heat waves, wildfires, rainfall and sea level rise — will only grow more severe in the coming years.

I don’t make this claim lightly. Among my colleagues in climate science, there are sharp divisions on this question, and some aren’t convinced it’s happening. Climate scientists generally focus on longer-term changes over decades rather than year-to-year variability, and some of my peers in the field have expressed concerns about overinterpreting short-term events like the extremes we’ve seen this year. In the past I doubted acceleration was happening, in part because of a long debate about whether global warming had paused from 1998 to 2012. In hindsight, that was clearly not the case. I’m worried that if we don’t pay attention today, we’ll miss what are increasingly clear signals.

Comments 1 to 4:

  1. Can you explain why it's been the coldest summer on record in the UK?

    Moderator Response:

    [BL] Such blatant, unsupported, erroneous claims are not welcome here. There is no need for anyone to "explain" something that has not happened.

    In comment #3, Rob Honeycutt has posted data that shows that your claim is not true. In addition, a simple web search provides reports that contradict your claim, such as:

    Record-breaking June temperatures means that the UK has had one of its ten warmest summers on record, despite an unsettled July and August, according to provisional Met Office figures. Meteorological summer 2023 was the eighth warmest on record by mean temperature, thanks largely to June’s record breaking temperatures, in a series which dates back to 1884.



    Please note that posting comments here at SkS is a privilege, not a right.  This privilege can be rescinded if the posting individual treats adherence to the Comments Policy as optional, rather than the mandatory condition of participating in this online forum.

    Please take the time to review the policy and ensure future comments are in full compliance with it.  Thanks for your understanding and compliance in this matter.

    If you wish to continue posting here, your habit of drive-by statements with little supporting evidence and no responses to criticism will not be allowed. Unless you return to this thread and do at least one of the following, any future posts will be subject to deletion with a pointer back to unfinished business here.

    • Admit that your above statement is wrong.
    • Provide supporting evidence of your statement, in the form of
      • a clear definition of the area you refer to as "the UK",
      • a clear indication of the period of time you consider to be "summer",
      • a clear indication of the period of time your claim of a "record" covers,
      • and a link to the source of data that you have used to draw your conclusion.


  2. Davz... I'm not sure there's a point to explaining it to you since you never stick around long enough to listen or discuss any issue. You merely make drive-by comments and disappear.

  3. And just to pre-bunk Davz' claim... 

    0 0
  4. Berkeley Earth also has temperature updates on a monthly basis. The graphics for each month include maps showing where the monthly temperatures are in the 5 hottest or 5 coldest values in the record.

    I wonder if Davz can tell us where on these maps we'll find the UK?
