Climate scientists slam the WSJ in this long rebuttal to a trashy editorial on climate denial. The first half of the piece are dozens of signatures, so you’l have to scroll scroll scroll to get to the red meat. But it’s well worth your time. A sampling:
(i) The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.
(ii) Most of the increase in the concentration of these gases over the last century is due to human activities, especially the burning of fossil fuels and deforestation.
(iii) Natural causes always play a role in changing Earth’s climate, but are now being overwhelmed by human-induced changes.
(iv) Warming the planet will cause many other climatic patterns to change at speeds unprecedented in modern times, including increasing rates of sea-level rise and alterations in the hydrologic cycle. Rising concentrations of carbon dioxide are making the oceans more acidic.
(v) The combination of these complex climate changes threatens coastal communities and cities, our food and water supplies, marine and freshwater ecosystems, forests, high mountain environments, and far more.

Scientists have shown that a newly discovered molecule in Earth’s atmosphere has the potential to play a significant role in off-setting global warming by cooling the planet.
In a breakthrough paper published in
Science, researchers from The University of Manchester, The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of Criegee biradicals.
These invisible chemical intermediates are powerful oxidisers of pollutants such as nitrogen dioxide and sulfur dioxide, produced by combustion, and can naturally clean up the atmosphere.
Although these chemical intermediates were hypothesised in the 1950s, it is only now that they have been detected. Scientists now believe that, with further research, these species could play a major role in off-setting climate change.
The detection of the Criegee biradical and measurement of how fast it reacts was made possible by a unique apparatus, designed by Sandia researchers, that uses light from a third-generation synchrotron facility, at the Lawrence Berkeley National Laboratory’s Advanced Light Source.
The intense, tunable light from the synchrotron allowed researchers to discern the formation and removal of different isomeric species — molecules that contain the same atoms but arranged in different combinations.
The researchers found that the Criegee biradicals react more rapidly than first thought and will accelerate the formation of sulphate and nitrate in the atmosphere. These compounds will lead to aerosol formation and ultimately to cloud formation with the potential to cool the planet.

Japanese breakthrough will make wind power cheaper than nuclear
A surprising aerodynamic innovation in wind turbine design called the ‘wind lens’ could triple the output of a typical wind turbine, making it less costly than nuclear power.
