The National Oceanic and Atmospheric Administration’s Global Monitoring Laboratory on Monday released data showing the concentration of carbon dioxide in the atmosphere increased by 3.75 parts per million in 2024. That…Continue readingIs the planet losing one of its best ways to slow climate change?

The dangers of a collapse of the main Atlantic Ocean circulation, known as AMOC, have been “greatly underestimated” and would have devastating and irreversible impacts, according to an open letter released…Continue reading‘We don’t know where the tipping point is’: climate expert on potential collapse of Atlantic circulation
The timeline, published Thursday in the journal Science, is the most rigorous reconstruction of Earth’s past temperatures ever produced, the authors say. It shows the intimate link between carbon dioxide and…Continue readingScientists have captured Earth’s climate over the last 485 million years. Here’s the surprising place we stand now.
Today’s rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years. Previous research showed that during the last ice age, which…Continue readingChemical analysis of natural CO₂ rise over the last 50,000 years shows that today’s rate is 10 times faster
A massive new review of ancient atmospheric carbon-dioxide levels and corresponding temperatures lays out a daunting picture of where the Earth’s climate may be headed. The study covers geologic records spanning…Continue readingA New 66 Million-Year History of Carbon Dioxide Offers Little Comfort for Today
By Christoper Ketcham The Intergovernmental Panel on Climate Change has assumed Nordhaus is to be trusted. The integrated assessment models used at the IPCC are based on Nordhausian visions of adaptation…Continue readingWhen Idiot Savants Do Climate Economics
If we look even farther back, to the previous interglacial period, which peaked around 125,000 years ago, we do find evidence of warmer temperatures. The evidence suggests the long-term average temperature…Continue readingIs it really hotter now than any time in 100,000 years?
