The data here’s from 2023,
The earth, for sure, is warming rapidly.
Careful worldwide measurement since 1860,
Show that temperatures have increased almost 2ºC.
All fuels and bovines give off methane emissions;
Fertilizers emit nitric oxide;
Air conditioning means free fluorocarbons;,
These warm the earth as much as carbon dioxide.
Hot spells and fires occurred in other centuries.
They exceeded, statistics show, those of today .
Region’s climate’s passed through long extremes:
Hurricanes, floods and droughts extraordinary.
Rhymed poetry is not the place to wonder,
What future rise in temperature we will know;
Hot climate costs and benefits to ponder,
If certain sorts of energy should grow.
How hot? Large models greatly disagree.
So future folks will have to wait and see.
