“The thing to remember is that drought is a very complex phenomenon. For one, drought is not just precipitation. Drought is also soil moisture and streamflow. This is an important distinction, because it means that other processes that may be affected by climate change (e.g., evaporation) can play a role in increasing drought, even if precipitation does not change.”

“The decreases have accelerated since the 1990s and have been part of a consistent suite of changes in the Arctic, including rising atmospheric temperatures, melting land ice, thawing permafrost, longer growing seasons, increased coastal erosion, and warming oceans. Overall, it has been a consistent picture solidly in line with the expectations of the warming climate predicted from increases in greenhouse gases. In particular, modeled sea ice predictions showed marked Arctic sea ice decreases, and the actual decreases even exceeded what the models predicted.”

The Earth’s climate has been quite stable over the past 11,000 years, playing an important role in the development of human civilisation. Prior to that, the Earth experienced an ice age lasting for tens of thousands of years. The global average temperature was around 4C cooler during the last ice age than it is today. There is a real risk that, if emissions continue to rise, the world warms more this century than it did between the middle of the last ice age 20,000 years ago and today.
One of the biggest outstanding questions of the COVID-19 pandemic is the origin of SARS-CoV-2, the coronavirus responsible for the…
