2024 SkS Weekly Climate Change & Global Warming News Roundup #15 - Skeptical Science (Apr 14) |
|
Apr 14 · Our story of the week is about adults in the room setting terms and conditions of good behavior. Here it's not parents telling children what to do but instead the widely adopted, mutually agreed system of coercive behavior modification we call "rule of law." Legislators providing courts of justice with laws to apply are how we formalize overcoming widely harmful selfish actions— or negligent inactions. These are our proxy adults telling us what we can't do or must do— our aspirations for better nature given teeth. We could wish that we were all so perfect as to never need grownup guidance of a kind leading to fines or imprisonment, but if anything can serve to illustrate ... Read more ...

2024 SkS Weekly Climate Change & Global Warming News Roundup #16 - Skeptical Science (Apr 21) |
|
Apr 21 · Our story of the week hinges on these words from the abstract of a fresh academic publication:
Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate ...

At a glance - Is the science settled? - Skeptical Science (Apr 16) |
|
Apr 16 · On February 14, 2023 we announced our Rebuttal Update Project. This included an ask for feedback about the added "At a glance" section in the updated basic rebuttal versions. This weekly blog post series highlights this new section of one of the updated basic rebuttal versions and serves as a "bump" for our ask. This week features "Is the science settled?". More will follow in the upcoming weeks. Please follow the Further Reading link at the bottom to read the full rebuttal and to join the discussion in the comment thread there.
Science, in all of its aspects, is an ongoing matter. It is based on making progress. For a familiar example, everyone knows that the dinosaurs died ... Read more ...

EGU2024 - An intense week of joining sessions virtually - Skeptical Science (Apr 19) |
|
Apr 19 · Note: this blog post has been put together over the course of the week I followed the happenings at the conference virtually. Should recordings of the Great Debates and possibly Union Symposia mentioned below, be released sometime after the conference ends, I'll include links to the ones I participated in.
This year's General Assembly of the European Geosciences Union (EGU) started on Monday April 15 both on premise in Vienna and online as a fully hybrid conference. This year, I decided to join virtually for the whole week, picking and chosing sessions I was interested in. At the time of publication this blog post was still an evolving compilation - a kind of personal diary - ... Read more ...

Fact Brief - Did global warming stop in 1998? - Skeptical Science (Apr 13) |
|
Apr 13 · As a strong El Nino year, 1998 featured a significant spike in global temperatures. El Nino is the warm phase of a cyclic climatic pattern where sea temperatures in parts of the Pacific swing higher or lower than average. The 1998 El Nino stood out above the rising temperature trendline that is due to manmade global warming.
However, the long-term upward trend in globally-averaged temperatures has continued. In the past quarter century, the top ten hottest years on record have all occurred since 2010.

How extreme was the Earth's temperature in 2023 - Skeptical Science (Apr 17) |
|
Apr 17 · In 2023, the Earth reached temperature levels unprecedented in modern times. Given that, it’s reasonable to ask: What’s going on? There’s been lots of discussions by scientists about whether this is just the normal progression of global warming or if something we don’t understand is happening — in other words, we’ve broken the climate.
In this post, I compare the observational temperature record to an ensemble of state-of-the-art CMIP6 models to see exactly how unusual 2023 was. It turns out that 2023 is just not that unusual when compared to the model ensemble.
Let’s start with observations. I’m going to be using the ... Read more ...

New Research for Week #16 2024 - Skeptical Science (Apr 18) |
|
Apr 18 · Glacial isostatic adjustment reduces past and future Arctic subsea permafrost, Creel et al., Nature Communications:
Sea-level rise submerges terrestrial permafrost in the Arctic, turning it into subsea permafrost. Subsea permafrost underlies ~ 1.8 million km2 of Arctic continental shelf, with thicknesses in places exceeding 700 m. Sea-level variations over glacial-interglacial cycles control subsea permafrost distribution and thickness, yet no permafrost model has accounted for glacial isostatic adjustment (GIA), which deviates local sea level from the global mean due to changes in ice and ocean loading. Here we incorporate GIA into a pan-Arctic model of subsea ... Read more ...

What is Mexico doing about climate change? - Skeptical Science (Apr 15) |
|
Apr 15 · The June general election in Mexico could mark a turning point in ensuring that the country’s climate policies better reflect the desire of its citizens to address the climate crisis, with both leading presidential candidates expressing support for renewable energy.
Mexico is the 10th-most populated country with the 15th-largest economy and is also the 11th-most climate-polluting country in the world.
In international surveys conducted in 2022 and 2023, Mexico had one of the highest percentages of citizens worried about human-caused climate change at 92%, compared to just 63% of Americans.* And 88% of Mexican respondents reported that they consider climate change ... Read more ...
