While most people seem to focus on air temperature as the only indication of climate change, most especially when a single winter is particularly cold or snowy and not even on global average temperatures, it's the oceans that are still rapidly changing. It's nice that global temperatures are not increasing as fast at the moment, but it of course doesn't mean any warming has stopped.
We probably know a whole lot less about what warming oceans might do compared to what rising air temperatures might do.

Climate change is one of those issues that is not going to be a top priority until things change drastically in developed countries. Then it will be about how bad things will get before maybe enough can be done to halt future changes, if possible. Things are going to be increasingly very different by the end of this century. The longer humans continue to contribute to warming beyond the Earth's ability to cope, the longer it will take for the some things that can recover to recover. And there is no way to know what will recover. How long before ice sheets increase to what they used to be? Will currents return to what they are now if they change? Who knows how long the sea level might take to recover and for sea life to rebound. (the species that survived) Who knows for land areas. Farming is hard enough, just wait until there is more people and probably shrinking, or at the very least, moving, growing regions. I can't imagine how coastal cities are going to move inland when the sea level rises and then back to where they were if the sea level recovers eventually. (And constantly moving to adapt to those changes. Or if things change too rapidly, forget about having coastal cities, just move the ports as needed.) It's ridiculous how insane things could get simply because some people are too scared to act at the moment. (I can imagine what future politicians will say, like "no one else did anything either" and "we didn't know they were serious") |
