To much fanfare, global leaders have agreed to tackle the climate crisis by ratifying the Paris climate agreement, but a group of esteemed scientists is warning that current pledges to reduce emissions are far from sufficient and, in fact, put the world on track to reaching the dangerous 2°C climate threshold by 2050.
"The pledges are not going to get even close," said Sir Robert Watson, former chair of the Intergovernmental Panel on Climate Change (IPCC), and lead author of a new report out Thursday. "If you governments of the world are really serious, you're going to have to do way, way more."
Aptly titled The Truth About Climate Change, the report, put forth by the Argentina-based Universal Ecological Fund (Fundación Ecológica Universal FEU-US), comes amid a rash of new research, all suggesting that key global warming thresholds will be reached much more rapidly than previously thought.
Forget Paris, Scientists Say 'Radical Change' Only Way to Stay Below 2 Degrees by Lauren MaCauley, Common Dreams, Sep 30, 2016
Using the metric of comments garnered, the two most popular articles posted on SkS during the past week are:
New research suggesting that the planet might already be committed to vastly greater warming than previously thought is being dismissed as deeply flawed by prominent climate scientists.
A study published today in one of the world's top science journals, Nature, offers the most complete reconstruction to date of global sea-surface temperatures for the past two million years—a valuable addition to the climate record, scientists say.
But the conclusions the study's author drew from that research—that even preventing any further increase of greenhouse gases in the atmosphere could still leave the Earth doomed to a catastrophic temperature rise of up to 7 degrees Celsius (about 13 degrees Fahrenheit)—isn't supported by the data, several top scientists said.
"This is simply wrong," said Gavin Schmidt, chief of NASA's Goddard Institute for Space Studies.
Jeffrey Severinghaus, a paleoclimatologist at Scripps Institution for Oceanography in San Diego, was equally vehement, arguing that the study's result isn't logical: "It's based on a fundamental mistake," he said. "The problematic conclusion doesn't flow from the main meat of the paper."
Global Warming Is Real—But 13 Degrees? Not So Fast by Graig Welch, National Geographic, Sep 26, 2016

Professors weigh in on the climate change debate by Alexandra Karlesses posted on The Review (University of Delaware) includes:
Ninety to 100 percent of publishing climate scientists have opposing views to Legates, according to John Cook, a supporter of climate change and the author of “Skeptic Science,” a blog that maintains that human-caused climate change is occurring.
In his article, Scientific Consensus: Why Should We Accept It? posted on Futurism, Robert Sanders writes:
A recently published paper by John Cook along with seven other authors of climate change studies found that 97% of publishing climate science endorse the consensus position of anthropogenic climate change. Further, the paper found that the studies conducted by more expert scientists reaffirmed the consensus more.

Climate Feedback's team of experts analyze the article, “Climate Exaggeration is Backfiring” by Robert Bradley Jr. (Forbes, Sep 23, 2016) and concludes:
Nine scientists analyzed the article and estimated its overall scientific credibility to be ‘very low’.
