A potential rule of thumb for hourly rainfall?

Future global warming will be accompanied by more intense rainfall and flash floods due to increased evaporation, as a consequence of higher surface temperatures which also lead to a higher turn-around rate for the global hydrological cycle. In other words, we will see changing rainfall patterns. And if the global area of rainfall also shrinks, then a higher regional concentration of the rainfall is bound to lead to more intense downpours (the global rainfall indicator is discussed here).

Looking for help with an electricity tax-swap idea

Filed under: — group @ 3 March 2021

Guest commentary from Yoram Bauman

Everyone from Treasury Secretary Janet Yellen to Elon Musk thinks that putting a price on carbon is an important step in tackling climate change. Politically, however, carbon taxes and cap-and-trade systems face an uphill battle, in part because they could drive up the prices of household basics like gasoline and electricity. There are many worthy proposals for addressing this concern, mostly focused on the idea of using carbon pricing revenue to pay for things like per-capita dividends, green investments, or reductions in payroll taxes. 

But what if you could put a price on carbon without driving up consumer prices? In California, for example, the impact of the cap-and-trade system on residential electric bills is reduced substantially by the semi-annual Climate Credits that households receive on their bills.

A bi-monthly open thread on climate solutions.

Regional information for society (RifS) and unresolved issues

It’s encouraging to note the growing interest for regional climate information for society and climate adaptation, such as recent advances in the World Climate Research Programme (WCRP), the climate adaptation summit CAS2021, and the new Digital Europe. These efforts are likely to boost the Global Framework for Climate Services (GFCS) needed as a guide to decision-makers on matters influenced by weather and climate.

A new open thread for climate solutions in the new year (and the soon-to-be new US administration actions). As for the climate science open threads, please try to renew your commitment to constructive dialog that prioritises light over heat (like LED bulbs for instance!). Thanks!

Denial and Alarmism in the Near-Term Extinction and Collapse Debate

Guest article by Alastair McIntosh,  honorary professor in the College of Social Sciences at the University of Glasgow in Scotland. This is an excerpt from his new book, Riders on the Storm: The Climate Crisis and the Survival of Being

cover art for Riders on the StormMostly, we only know what we think we know about climate science because of the climate science. I have had many run-ins with denialists, contrarians or climate change dismissives as they are variously called. Over the past two years especially, concern has also moved to the other end of the spectrum, to alarmism. Both ends, while the latter has been more thinly tapered, can represent forms of denial. In this abridged adaptation I will start with denialism, but round on the more recent friendly fire on science that has emerged in alarmism.
