Another great synopsis by Bob Berwyn. One weird thing about the debate between “it’s worse than we thought” and “the truth is bad enough” is the latter’s “truth” is pretty much in line with the former’s vision of what is expected to be “worse”😬

Wow, the whole Ireland (and parts of the UK) are under red warning. We are talking about truly historically powerful storm with wind gusts over land areas (!) exceeding 36 m/s. Stay safe! Minimum pressure could reach all-time record lows (~940 hPa) in the Scotland area.

Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊

Scientists developed the first climate models in the late 1960s (for which the Nobel Prize in physics was recently awarded!). How have these models held up against what happened in the real world after they were published? Surprisingly well, it turns out:

So, we have the global temperatures for the whole of 2024. It was the warmest year on record (1850-2024) across six widely used datasets: HadCRUT5, Berkeley Earth, GISTEMP, NOAAGlobalTemp, ERA5 and JRA-3Q.

Here's my visual explanation of why we have not yet reached 1.5°C even though 2024 was likely warmer than 1.5°C. 2024 shows us how close we are, but the underlying warming is still under 1.5°C.

Really interesting figure in the @copernicusecmwf.bsky.social Global Climate Highlights 2024. 1877-78 really stands out as an extreme years. This is the period of the 1876-78 global famine that caused an estimated 50million death. climate.copernicus.eu/global-clima...

The Paris agreement target of 1.5°C refers to the long-term average. A single year above 1.5°C does not mean the target has been breached but it does mean it is getting closer. www.bbc.co.uk/news/article...

Wildfires aren’t a problem in the UK, right? Wrong. Not on the same scale as we are seeing in LA, but there are thousands of wildfires every year in the UK. In the heatwave of July 2022 wildfires broke out in London. Our new paper explores the risks: doi.org/10.1002/cli2...

Occasional reminder that there’s no, “it’s too late, its over” for anthropogenic climate change. Every molecule of CO2 that doesn’t go into the atmosphere makes a difference. Preventing 0.1 degree of warming makes a difference. Every bit of climate resilience we build together makes a difference.

What is driving the recent rate of global warming? That would be CO2, of course. Not as exciting as SO2, but climate change cannot be solved without getting CO2 emissions to zero. SO2 drives short-term changes, most recently, the decline in SO2 in China. www.theclimatebrink.com/p/exploring-...

Climate models have many limitations. In the climate science community these are generally understood but often not communicated. Climate scientists need to be more open about these limitations and the potential implications for assessment of climate risk at regional and local scales.

I have a new analysis over at The Climate Brink exploring how rates of warming have changed over the past century. Post-1970, GHGs (CO2, CH4, etc.) would have led to just under 0.2C per decade, but falling aerosols (SO2) have increased that rate to 0.25C. www.theclimatebrink....

I am an advocate for climate model democracy. Treat each model as an equally plausible future. Where appropriate this can be done using a global warming level approach.
