Skeptical Science examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other planets are warming too' are examined to see what the science really says.

Ice acceleration and rotation in the Greenland Ice Sheet interior in recent decades, Løkkegaard et al., Communications Earth & Environment:
In the past two decades, mass loss from the Greenland ice sheet has accelerated, partly due to the speedup of glaciers. However, uncertainty in speed derived from satellite products hampers the detection of inland changes. In-situ measurements using stake surveys or GPS have lower uncertainties. To detect inland changes, we repeated in-situ measurements of ice-sheet surface velocities at 11 historical locations firs ..read more

For the residents of Dassa-Zoumè, a city in the West African country of Benin, choosing between drinking water and having enough food has become a worrying dilemma.
“Last year, our horticultural production plummeted due to water scarcity,” said Chantal Agbangla, a farmer residing in Soclogbo, a town located about 30 minutes by car from the capital of Dassa-Zoumé. “We had to travel nine kilometers ..read more

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 "The difference between weather and climate". 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.

Public transportation riders in Pune, India, love the city’s new electric buses so much they will actually skip an older diesel bus that arrives earlier to wait for a smoother, cooler ride in a new model. This has fed a new problem: overcrowding. Fortunately, more new buses are on the way.
Last fall, India’s Ministry of Housing and Urban Affairs launched a $7 billion initiative to support 10,000 new electric buses in 169 Indian ..read more

A listing of 29 news and opinion articles we found interesting and shared on social media during the past week: Sun, April 14, 2024 thru Sat, April 20, 2024.
Story of the week
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 ..read more

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 th ..read more

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 ..read more

This is a re-post from Andrew Dessler at the Climate Brink blog
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.
from the Washington Post
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 tu ..read more

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 ..read more
