...i.e. how future climate will impact the environment and society. Specifically, in this paper, we assessed how future climate scenarios will impact power generation at the portfolio level. Check the paper to see which variables were predicted to have the highest impact!

It was a great pleasure to be part of this project. Before that, my main focus was on remote sensing, which allows me to see the past and the current image of the Earth. This project introduced me to climate models, with which we can "see" the future.

Multi-hazard physical climate risk to power generation projects, for example through water scarcity or extreme weather, can be estimated from publicly available global datasets. @luo_tianyi @YanChengRS nature.com/articles/s43247-0…

How many of species of tree are there? New study in @PNASNews estimates 73,000, of which 9200 have yet to be discovered deep in the tropical forests pnas.org/content/119/6/e2115…

Amid record-dry Jan across portions of Sierra Nevada, California snowpack has now fallen below avg for date--remarkable given it was ~160% of avg for date in late Dec! These percents of average will continue to plummet over next 2 wks as dry conditions continue. #CAwx #CAwater

Why are we interested in characterizing the rate at which forests return following disturbance? 👇 #forestrecovery bit.ly/3KHyUJq

#Drought and its consequences is one of the 4 most critical natural hazards in the mountain areas of Southwest Europe, together with floods, fires and soil degradation 🍂☀🔥💦 Want to know more? Have a glance to the @montclima seminar conclusions 👉🏼 bit.ly/3lapE6a

Megadroughts are not new for North America, but research by climate scientists like Lamont's Jason Smerdon finds that current one is exceptional even compared to past extremes: this is probably most severe 22-year drought in 1,000+ years. Via @NZZenglish. nzz.ch/english/at-22-year-ma…

The megadrought in the western US is already entering its 22nd year. The causes are partly natural,...

The long-lasting drought is being exacerbated by unusually cool waters in the tropical Pacific. Researchers are also assessing the influence of global warming.

Inspired by your paper, I created an #EarthEngine script that expands the acquisition time analysis to include Landsat 5 and Sentinel-2, and produces an interactive chart. #ReproducingResearch colab.research.google.com/gi…
