The flooding in the Middle East desert city of Dubai earlier in the week followed record-breaking rainfall. It doesn't rain very often here like other desert areas, but like the deadly floods in Libya last year showed, these rain events are likely becoming more extreme due to global warming.

I remember Atlantic 252 that was on the 18Z as well, could be proper grim. Still we’ve got sunshine this morning although it’s really fresh outside! Could be the first day of the year to get to 10hours for sunshine - tragically late if that is the case.

Abstract Here, we show that the Last Glacial Maximum (LGM) provides a stronger constraint on equilibrium climate sensitivity (ECS), the global warming from increasing greenhouse gases, after accounting for temperature patterns. Feedbacks governing ECS depend on spatial patterns of surface temperature (“pattern effects”); hence, using the LGM to constrain future warming requires quantifying how temperature patterns produce different feedbacks during LGM cooling versus modern-day warming. Combining data assimilation reconstructions with atmospheric models, we show that the climate is more sensitive to LGM forcing because ice sheets amplify extratropical cooling where feedbacks are destabilizing. Accounting for LGM pattern effects yields a median modern-day ECS of 2.4°C, 66% range 1.7° to 3.5°C (1.4° to 5.0°C, 5 to 95%), from LGM evidence alone. Combining the LGM with other lines of evidence, the best estimate becomes 2.9°C, 66% range 2.4° to 3.5°C (2.1° to 4.1°C, 5 to 95%), substantially narrowing uncertainty compared to recent assessments. https://www.science.org/doi/10.1126/sciadv.adk9461

I remember Atlantic 252 that strip of the lowest temperatures is in line with an area of rain.

Another clear blue, sunny start to the day here. Last few days, despite being a tad on the fresh side, have been pretty decent overall really for mid April. Nout wrong with a NW’er here. More please but cut the breeze!

Spring has suddenly turned very cold in these parts. Last weekend sitting outside and drinking beer in warm sunshine. So far this morning 17cm of fresh snowfall and temp - 1c. Great for snow farming up on the berg. C
