How might solar geoengineering affect tropical rainfall and the Indian monsoon? Govindasamy Bala explains in a talk at Carnegie Science's Dept. of Global Ecology on the Stanford University campus.

What are the key physical science "unknown unknowns" related to stratospheric solar geoengineering?

More wind and solar does not necessarily mean less coal, oil and gas. www.theguardian.com/environment/...

Fossil fuel use reaches global record despite clean energy growthwww.theguardian.com Report finds developing countries are increasing reliance on coal, gas and oil as overall demand for energy rises

Consequences of actions are empirical questions. What outcomes are acceptable is a normative question. Planetary boundaries are created by people. Scientific information is relevant, but not determinative. thebreakthroughjournal.substack.com/p/how-planet...

Coastal subsidence meets global sea level rise in the American South. www.washingtonpost.com/climate-envi...

Where seas are rising at alarming speedwww.washingtonpost.com Seas in the Southern United States have risen dramatically since 2010. The extra water has upended life — flooding homes, choking septic systems and deluging roads.

One success strategy: Excellence and kindness. You need to do excellent work and you need to be the kind of person that people want to work with.

The North Sea may not have the most reliable winds, but the best place to build wind is determined by demand and other economic factors, and not only geophysical considerations. www.nature.com/articles/d43... www.nature.com/articles/s43... kencaldeira.com/2024/03/wher...

Is there a tension between doing the most useful studies and doing the studies most likely to be published in a high-profile venue?

The Guardian did a story on our study of areas with the most abundant and reliable wind resources. Congratulations, Enrico Antonini. Thanks, Kate Ravilious. kencaldeira.com/2024/03/wher... www.nature.com/articles/s43... www.theguardian.com/news/2024/ap...

Citations were always gameable and imperfect. Apparently, they may soon be so easily gamed as to be useless. What should be done? Proposals?

The scientific community is definitely going to want to think abt trustworthy citation metrics, so $50 on Fiverr can't "boost citations and h-index." The answer has got to be: 'build institutions that can certify.' NIH? Prof societies? 🧪 www.fiverr.com/brain...

There has been a lot of talk of fraud in science, but we need to recall that this is against a background of tremendous scientific advance. Scientific fraud is the exception, the man bites dog story. The everyday story is scientists making discoveries that drive our economy and improve our lives.

Where is there a lot of weather variability in wind power? Europe has challenges to overcome whereas the American Midwest has relatively reliable winds. Have a look at this blog post and the associated paper. kencaldeira.com/2024/03/wher...

Where are the abundant and reliable winds? Please have a look at this blog post that explains our recent study. kencaldeira.com/2024/03/wher...
