Evidence for global warming

What the science says...

Select a level... Basic Intermediate

There are many lines of independent empirical evidence for global warming, from accelerated ice loss from the Arctic to Antarctica to the poleward migration of plant and animal species across the globe.

Climate Myth...

It's not happening

"...these global warming studies that now we're seeing (are) a bunch of snake oil science." (Sarah Palin)

The evidence for global warming is being meticulously accumulated by scientists all over the world. This evidence includes the following independent observations that paint a consistent picture of global warming:

Comments 1 to 11:

  1. A valuable resource! Thanks!
  2. Have you thought of adding to this list the decline in lizard populations, and the warming of Lake Tanganyika?
    Response: I hadn't but I have now :-) Thanks for the suggestion. I've also added both to the positives and negatives of global warming.
  3. The green tab for this post needs fixing.
  4. Let's get cracking on updating this article!
  5. On the comment stream at Alex Knapp's Forbes blog:

    Daniel Fisher (Forbes staff): "I am not sure the debate is over whether the climate is warming – obviously it has been getting warmer since the last Ice Age, which was a very short time ago. The question is whether that increase is accelerating in a non-random way, and the acceleration is caused by the measured increase in atmospheric CO2. Does this new method help unravel that?"

    Bob Tisdale: "That would be difficult to show for a couple of reasons. First, the hypothesis of manmade global warming is only supported by general circulation models, which are known to be imperfect representations of the Earth’s climate systems. Second, that hypothesis is not supported by NOAA’s satellite-era sea surface temperature data or by NOAA’s ocean heat content data since 1955."

    Is Tisdale paid? 

  6. I think this answer ought to be updated with the more detailed graphic over here:

  7. 59F tomorrow for Buffalo.  15F above the daily average.   Should they now think that temperatures have risen >10 times faster than IPCC thinks?  Fact is, winter is coming, and it gets cold and snows a lot in Buffalo in the winter almost every year.  Sometimes it gets warm again.

    Ironically, though, the large amounts of lake effect snow have been linked to the warming of the lake, resulting in more evaporation, convective lift and, therefore, snow than previously seen.  It interacted with a large actic air mass, of the sort we've been seeing that last few years.  That pattern has also been attributed to global warming, though the jury is still out.

  8. I would like it very much is this type of article, or at least this one in specific, were updated with the latest numbers. In this new age of Trumpism, we need the best ammo available, please.

  9. Dennis, NOAA maintain a "State of Climate". For global view, updated Oct 2016, see https://www.ncdc.noaa.gov/sotc/global/201610

  10. I like that you devide and explain each indicator clearly. Every evidences are really make sense follow your claim, but I just wondering how can it happen because the weather is become really hot nowadays and seems going to be hotter and hotter? Also ice ages are become smaller than what it was. How can the result be the opposite with the indicators? Is it because of there areb still many factors going on? 

    Thank you XD 

  11. Please note: the basic version of this rebuttal has been updated on November 19, 2023 and now includes an "at a glance“ section at the top.
