Droughts, wet events made more frequent, intense by global warming: NASA-led study

Major droughts and pluvials - periods of excessive precipitation and water storage on land - have indeed been occurring more often, confirmed a new National Aeronautics and Space Administration(NASA)-led study.Droughts and floods will become more frequent and severe as our planet warms and climate changes, scientists have predicted, but detecting this on regional and continental scales has proven difficult, the study said. Two NASA, us, scientists examined 20 years of data from the NASA/German GRACE and GRACE-FO

A warmer world will make heat waves more frequent, says study

Composite of (a) 300-hPa geopotential height anomalies and (b) 2-m air temperature anomalies (shading, SI = 0.5°C) during the extreme heat summers over Western North America (WNA) in ERA5 data set. (c, d) are the same as (a, b), but for the MME from 15 CMIP6 models. The blue rectangles represent the region over WNA (40°–60°N, 128°–110°W). The anomalies are relative to 1981–2010.

Frequent Dry Spells Could Have Been Essential For Life to Emerge on Earth : ScienceAlert

How life emerged on Earth from an assortment of non-living molecules is a stubbornly enduring mystery. Experiments can show us how key steps might have happened, but for every leap forward there are confounding dead ends.Water, for instance, seems like an essential component of life from the very start. Yet the process of growing some of life's most vital components has a frustrating aversion to getting wet."We know amino acids are the building blocks of proteins and proteins are essential for life," says University of…
