“Pollution cuts have diminished “ship track” clouds, adding to global warming”
So during the age of sailing ships the oceans were warmer?
We’ve likely only had a 100 year period where we had a sufficient number of polluting ship to have made a difference
- wahern 3y agoThey're saying that these clouds have blunted the impact of CO2 emissions. Most of the CO2 increase (to ~420ppm) above pre-industrial levels (from ~275ppm) has occurred over the past 100 years; about half of it has only been since ~1990 (then ~350ppm).

Highly unlikely, because of the many other factors involved, such as a completely different overall climate situation during that time period; A climate not nearly as heavily affected by human actions as the climate of today, to name just one of the most glaringly obvious factors.
