Study 'finds that the radiative imbalance from greenhouse gases at the top of the atmosphere has increased over the past 27 years while the rate of global warming has unexpectedly decreased or 'paused' over the past 15+ years.'
'A paper published today in Atmospheric Chemistry and Physics finds that only about 3.75% [15 ppm] of the CO2 in the lower atmosphere is man-made from the burning of fossil fuels, and thus, the vast remainder of the 400 ppm atmospheric CO2 is from land-use changes and natural sources such as ocean outgassing and plant respiration.'
Dr. Motl mocks climate fears: 'It's nonsensical that when the climate apocalypse fails to materialize in the next 10, 20, 50, or 100 years, people will think that the Earth will just have been lucky. The atmospheric processes are affected by lots of chaotic, hardly predictable phenomena... In a few decades, it will be possible to see not only that the climate apocalypse will have not materialized; but also that its probability to emerge as of 2014 (and calculated with the hindsight that people will acquire in the future) will have been virtually zero.'
'As carbon dioxide levels rise worldwide, they could lose their ability to recognize each other, in effect becoming “friendless” wanderers who will hang out with just about anybody. That’s the short version of new research on climate change and fish behavior out of James Cook University in Queensland, Australia. A team led by Lauren Nadler wanted to know how fish will react to ocean acidification caused by more and more human-generated CO2 in the atmosphere...[In] CO2 levels comparable to what the IPCC estimates for 2100, the fish showed signs of developmental impairment: When put among schools of fish they grew up with and with ones they didn’t, they displayed no preference for hobnobbing with their old tank mates. They’d just as soon swim with strangers.'
