A 2008 paper by James Hanson, former Director of NASA’s Goddard Institute for Space Studies … showed the true gravity of the situation. In it, Hansen set out to determine what level of atmospheric CO2 society should aim for if humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted. His climate models showed that exceeding 350 parts per million of CO2 in the atmosphere would likely have catastrophic effects. We’ve already blown past that limit. Right now, environmental monitoring shows concentrations around 400 ppm.
There were no consequences. Real-world evidence clearly demonstrates that Hansen’s hypothesis is wrong. (Scientific method)
Also in the news is that the El Nino warming effect has ended, and things are getting colder.
Scientists were shocked by what they found when pouring over accounts from the famous South Pole explorers a century ago. The Antarctic Sea Ice is just about the same as it was 100 years ago according to the ships logs of Ernest Shackleton, in addition to other explorations in those waters. Scientists had only really looked at Antarctic sea ice levels from the 1950s onward, which shows a relative decline in sea ice. But researcher Dr. Jonathan Day and his team were the first to look at conditions prior to the 1930s. Current sea ice is just 14 percent smaller than the highest point of the 1900s and 12 percent greater than the lowest point.
Why is that a big deal? It shows that Antarctic sea ice has fluctuated throughout the 20th century—due to natural climate shifts, not man-made warming. The problem is that if you want to predict the state of the climate in a hundred and fifty years, you won’t know whether you were correct or not until 150 years from now, no matter how many computer programs you have or how many peer-reviewed papers you produce.
Arctic sea ice extent has shrunk more than 7 percent per decade since 1979 while Antarctic sea ice has actually grown about one percent per decade — despite what most climate models predicted.
A 2015 NASA study found Antarctica’s ice sheet increased in mass from 1992 to 2008. The study found ice gains in Eastern Antarctica more than offset ice loss from melting glaciers in the west.
Day’s study comes just after the British Antarctic Survey (BAS) found the collapse of a major South Pole was sparked by an El Nino during the 1940s, not man-made climate change.
