Extreme Weather #11 – Trends in Droughts – Rainfall
In #10 we saw an overview which included the idea that a rainfall deficit is one part of a soil moisture deficit. But it’s the part we can measure. AR6 says, p.1573: Global studies generally show no...

In #11 we looked at “droughts from rainfall”, i.e., rainfall deficits. There were regional variations but no obvious global trend. In fact, we expect more rainfall as the earth warms (warm air holds...

In #12 we saw that soil moisture droughts – agricultural and ecological droughts – have increased globally. I’ve been following the flow of AR6 in their discussion of recent trends. They do go on to...

Global temperature has been rising since around 1900, and CO2 is the principal cause. The physics behind the inappropriately-named “greenhouse effect” is certain, so burning fossil fuels, which adds...

In the last set of articles we’ve looked at past trends in extreme weather, following the flow of chapter 11 from the 6th assessment report of the IPCC. How do we know the cause of any changes? In...

In #1 we looked at some examples of natural variability – the climate changes from decade to decade, century to century and out to much longer timescales. How sure are we that any recent changes are...
