Why are temperatures and sea levels not higher?
Time lag. The increase in levels of CO2 (and other greenhouse gases) has been so rapid the worlds climate has to catch up.
We have committed ourselves to the sort of change outlined above. Jst to help it along the tropical rainforests are being destroyed at a record rate, whilst big Corporations are somehow claiming tree planting to offset their CO2 emissions.
Then as I walk into the sea of single use plastics that is the modern supermarket, apparently it's all fine because they are cuting back on plastic straws.
It's a mad world (which was a great track, though I prefer the angry sounding Tears for Fears original to Gary Jules depressing version.)
