Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

Scientists are sounding the alarm because this warming is shockingly bigbigger than what we would have expected given the long-term warming trend from fossil fuel-caused climate change. Albedo is the total reflection of incoming solar radiation by Earth. But why were 2023 and 2024 so warm? What is albedo?

AR6 of the best

Real Climate

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) 1981) which can be seen here.

Science denial is still an issue ahead of COP28

Real Climate

In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling. And yes, also the increase in back-radiation towards the Earth surface from the CO2 greenhouse effect is a measured fact. It’s not hard to understand.

Climate adaptation should be based on robust regional climate information

Real Climate

Chris Lennard from the University of Cape Town takes us through different aspects of climate change adaptation. The good news is that there are some initiatives on climate change adaptation which involve climate scientists such as the Infrastructure and Climate Network ( ICNet Global ).

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

Solar activity provides no alternative explanation for today’s climate change Dagsvik and Moen claim that recent research indicates that variations in the sun’s magnetic field are of great importance for long-term fluctuations in solar activity. Our job is to be thorough and verify questionable results. It has taken time.

A Total Eclipse of the Heat

Legal Planet

Read out of context, that description fits climate change too, of course. Millions of us hopped planes, booked expensive AirBnBs, and made all sorts of detailed plans to be in exactly the place that scientists told them to be months ago. “ So why do so many ignore scientists’ predictions about climate change?!!”

A Nobel pursuit

Real Climate

Last week, the Nobel physics prize was (half) awarded to Suki Manabe and Klaus Hasselmann for their work on climate prediction and the detection and attribution of climate change. This came as quite a surprise to the climate community – though it was welcomed warmly. But let’s go back to the beginning.
