Global Temperature Update for September 2020: +0.57 deg. C
by Roy W. Spencer, Ph. D. The Version 6.0 global average lower tropospheric temperature (LT) anomaly for September, 2020 was +0.57 deg. C, up from from the August, 2020 value of +0.43 deg. C. The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over……
On noes! Antarctic sea ice may not cap carbon emissions as much as previously thought
From the “that darned sea ice is messing up our model” department and MIT News. Study suggests sea ice blocks the flow of carbon both into and out of the ocean, in roughly equal measure. The Southern Ocean surrounding Antarctica is a region where many of the world’s carbon-rich deep waters can rise back up……

Study: China’s Clean Air Policies are Triggering Additional Global Warming
According to a study whose authors include Ken Caldeira, China’s efforts to eliminate its infamous air pollution could cause an additional 0.1C NH warming, because less sunlight will be reflected by aerosols. However, despite suggesting China’s improved air quality is a “climate setback”, Caldeira acknowledged cleaner air is a net improvement.…
New technology uses NOAA data to provide faster weather/disaster warnings
Mayday.ai applies artificial intelligence to NOAA satellite imagery to detect natural disasters, starting with wildfires In 2017, as Kian Mirshahi watched wildfires rage across his home state of California, he wondered if there might be a way to get real-time information to first responders and citizens to help coordinate actions on the ground. More specifically,……
New Solar Orbiter data reveals the sun at its quietest
Three of the Solar Orbiter spacecraft’s instruments, including Imperial’s magnetometer, have released their first data. The European Space Agency’s Solar Orbiter spacecraft launched in February 2020 on its mission to study to Sun and it began collecting science data in June. Now, three of its ten instruments have released their first tranche of data, revealing the state……
