In Matt Ridley’s recent Wall Street Journal article he claimed that a rise of 1.2 degrees over the next 70 years would be largely beneficial. He doesn’t back this up with any evidence and, as far as I’m aware, there really is none. There may be regions where the effects could be positive, but many regions where they will likely be negative. I’m, however, no expert at this so thought I would reblog this interesting post from someone who appears to know more than me.
Surprisingly, the most common question I get asked isn’t about whether climate change is happening. More typically, people are curious about how I feel about climate change and often ask about what worries me about the future.
Many of the scientific concepts that we use to talk about possible future climatic change are just that – complex scientific concepts. So when asked, I like to talk about how I feel about potential future climate change.
For example, climate scientists are concerned with pinning down a number for the Equilibrium Climate Sensitivity (ECS). This refers to the global average surface warming response to a doubling of atmospheric carbon dioxide concentrations after the system has settled and reached a new steady state.
In the real world, it could take hundreds of years or longer to see what temperature change would result from carbon dioxide doubling.
This concept is hard to…
