Quote MessageHow has climate change actually changed the ‘typical’ southwest weather patterns over the last couple of decades - things like more intense Atlantic storms, drier springs, or shifts in mizzle frequency - and what do you think we’ll notice most in the coming 10–20 years?
Answer:
Hi Mike, climate change (global warming) has changed the weather in the South West quite significantly in the last 50 years.
For every 1C (33.8F) rise in temperature the atmosphere can hold 7% more moisture, 2C (35.6F) and its 14% more.
We are now warmer through all of our seasons so rainfall events are going to continue to be more intense, summer heatwaves more likely, and storms more violent since a warmer atmosphere has more energy.
Frosts may well become a thing of the past, winters will be milder and wetter, summers drier and hotter but when summer rainfall events occur they are likely to bring torrential downpours.
