From 6000 years ago until the industrial revolution the planet cooled down, even though greenhouse gases increased! (likely due to aerosol emissions, which helped stabilize Holocene climate!)
There's been quite some attention to warming of the tropical area of the North Atlantic Ocean in recent weeks.
The rest of the North Atlantic saw much faster and more consistent warming in the past 3.5 years however.
See annual and March-April-May trends:
And the same for the tropical North Atlantic:
And for the whole of the Northern Hemisphere mid latitudes.
This is the area where we would expect the most Sea Surface warming (rate) increase, if ship sulfur emission reductions cause a large (regional) radiative forcing.
Here's a 8567 pixel #ShowYourStripes from the North Atlantic Ocean since 2000.
June 20 pales the warming from recent years:
Also see the Ocean Heat Content stripes.
Because about 90% of the heat from global warming goes into heating the oceans, this is one of the clearest signs of our warming world.
