The cool 2020 Spring is not just your local experience, it’s the result of Earth’s ocean cooling off after last summer’s warming in the Northern Hemisphere. The chart below shows SST monthly anomalies as reported in HadSST3 starting in 2015 through May 2020.
Which is it? Time Mag. goes both ways on volcanoes! Flashback 2014 Time Mag.: 'Volcanoes May Be Slowing Down Climate Change' - 'Research shows that large volcanic eruptions inject sulfur dioxide gas into the stratosphere. The gas forms tiny droplets of sulfuric acid, also known as “volcanic aerosols,” that can block sunlight. That cooling effect has been largely ignored by climate scientists until now, but it seems to partly offset the warming from human-caused changes in greenhouse gases.'
