“Paris climate pact looks pretty but smells bad”
Between the Ice Age and pre-industrial times, global mean temperature rose by about 6°C. But earth is now warming at a fearfully faster pace, so that temperature rose by about 0.7°C in the 20th century alone.
This is why there’s cause to cheer the Paris pact – where more than 190 countries have agreed to pursue efforts to limit global warming to 1.5°C above pre-industrial level. Make no mistake, this is a very ambitious pledge for the 21st century.
