Having a moment as I sign my book, Climate Dynamics, for Russell Ogle as we prepare to head out to the Hill to advocate for science funding as part of #AGU Days of Action. Thanks to AGU for organizing and supporting 100 earth scientists for this visit to Senate and Congressional offices .

Greenland ice melt and its contributions to sea level rise. 🧪

Time series of annual mean temperature anomalies (ºC) averaged over the U.S. Decreasing temperatures in mid-century, from 1960 to about 1980, were due to unregulated industrial pollution. Air quality regulations have improved our health, and at the same time unmasked the global warming signal.🧪

A figure for my class - time series of the global temperature anomaly. Uncertainties are indicated by the gray lines. They are minimal after about 1960 – before the steep rise of the last 40 years. Will these error bars now will start to increase due to the failure of the U.S. government?

The latest CO2 record from the Mauna Loa Observatory. (Thank you, NOAA!) Regular measurements, same method, since 1958. Incontrovertible. I think it's the most important geophysical record ever produced. Do you agree?

Here is the surface temperature anomaly (difference from the 1951-1980 mean) for the most recent decade (2015-2024) from NASA GISS in degrees C (multiple by 1.8 for Fahrenheit). Land has a lower heat capacity than ocean so it is warming more quickly. 🧪

My book, "Climate Dynamics, second edition" is now available as an ebook from Princeton University Press (PUP). Hardcopy available next month. Hoping this book helps people understand how the climate system works, and why it is changing. So excited to see it in print!! Thanks to PUP!! 🧪
