Former US Energy Department chief scientist Steven Koonin says sea levels rise at changing rates and sees ‘no signs’ of a climate apocalypse.
Here we continue our interview with Dr. Steven Koonin, chief scientist in the US Department of Energy during the Barack Obama administration and author of the just-published book, Unsettled: What Climate Science Tells Us, What It Doesn’t, And Why It Matters

When Philip Munday discussed his research on ocean acidification with more than 70 colleagues and students in a December 2020 Zoom meeting, he wasn’t just giving a confident overview of a decade’s worth of science. Munday, a marine ecologist at James Cook University (JCU), Townsville, was speaking to defend his scientific legacy.

But their work has come under attack. In January 2020, a group of seven young scientists, led by fish physiologist Timothy Clark of Deakin University in Geelong, Australia, published a Nature paper reporting that in a massive, 3-year study, they didn’t see these dramatic effects of acidification on fish behavior at all.

At Die kalte Sonne, Prof. Fritz Vahrenholt – one of the founders of Germany’s modern environmental movement – presents his monthly summary, which includes a look at global temperature and how the models are doing.
“The global mean temperature deviation of satellite-based measurements from the mean of the 1991 – 2020 period was -0.05 degrees Celsius in April 2021. Nevertheless, German courts have ruled that something has got to be done about the warming planet!

The cool La Niña situation over the recent months is still having an effect. According to the U.S. National Oceanic and Atmospheric Administration (NOAA), there is an 80% probability that La Niña will end between May and July. However, the agency expects a new La Niña to begin again in the fall.
The average temperature increase has been 0.14 degrees Celsius per decade. The model calculations, on which the IPCC’s recommendations are based, come up with a temperature increase that is twice as high for the same period (see chart below, source: R. Spencer 2021).
This striking deviation from the real temperature development is politically significant, because model forecasts are the basis for far-reaching decisions, such as constitutional court rulings.”
