Många anade att de förödande tornado-utbrotten i Kentucky var förstärkta av klimatförändringarna. Kopplingen är inte klarlagd, men här är några rön.
Kentucky faces greater tornado risks because of climate change
Determining the role of climate change in a single tornado is difficult, but climate change did play a role in the tornado system that hit Kentucky over the weekend, and extreme weather events like it will become more common as the planet warms.
The science is complicated, but the trends are clear:
• Climate change is making winter warmer. The unusually warm conditions this December put more energy in the atmosphere, charging the system that contributed to the tornado outbreak in Kentucky.
• The number of tornadoes touching ground during severe storm events has increased over the last 50 years.
• “Tornado Alley” is shifting north and east, putting western Kentucky in its cross hairs.
