The chart is actually not so terrifying once the cause of it was discovered. Basically, new regulations reducing sulfur content in ship fuel that went into effect in 2020 and put an end to an unintentional geoengineering experiment that had been running due to the enhanced cloud cover the sulfur dioxide particles were causing.
So this is a strong data point showing that solar geoengineering could work, if we resume it deliberately under more controlled conditions.
Just a friendly reminder that climate change was predicted well ahead of time, easily decades ago, with old predictive models turning out to have been decently accurate.
easily decades ago
Decades ago (in the early 2000s) it was considered settled science and taught in schools (in Canada at least). It was studied by scientists at oil companies decades before that. It’s been known for like 50 years now, almost an entire lifetime.
More than half of all the carbon emissions humans have ever produced were produced in those 50 years[1].
Also a reminder: oil corporations researched this, knew about it decades ago, and deliberately lied about what they knew.
They dance around the fact it’s human caused climAte catastrophe so brilliantly. Remember, it’s not 5 or 6 corporations,
It’s you didth recycling
