Call it another dispute about the “settled science” of climate change.https://amgreatness.com/2017/09/23/more-unsettled-science-on-climate-change/
According to a report published in Nature Geosciences last week, we have more time than we thought to stop the predicted meltdown of the planet. Not only are climate models way off—“running hot” by overestimating temperature increases—but the warming we were supposed to experience this century hasn’t happened as most climate models anticipated. What’s even more alarming to the climate tribe is that this study, “Emission budgets and pathways consistent with limiting warming to 1.5 [degrees Celsius],” is authored by several prominent climate scientists,, many of whom have warned of planetary doom if we don’t cap global warming within the 1.5 C range.
First, some background: Most climate agencies report the world has warmed by about 0.9 C since the late-1800s; climate scientists insist we need dramatic decreases in carbon dioxide emissions to keep the overall temperature increase to 1.5 C (or 2.7 degrees Fahrenheit) by the end of this century. This means Mother Earth has about 0.6 C left in her global warming thermometer before we break the glass. The entire raison d’etre for the Paris Climate Accord is to oblige nations immediately to cut carbon emissions so we can keep warming “well below” a 2 C rise over pre-industrial levels.
There have been varying, desperate pleas about how much time we have left to stop global warming. Some scientists lament that we are already past the point of no return. Others, including the former United Nations climate chief, warned in a paper published in June that we only have three years left to stop human-caused global warming and if “emissions continue to rise beyond 2020, or even remain level, the temperature goals set in Paris become almost unattainable.”
But this new paper suggests we have about 20 years until we will need a mass conversion to using solar panels and Teslas in order to bring total CO2 emissions to zero (a wholly punitive, unnecessary, and impossible goal.) The conclusion is based on a complicated calculation of how much of a “carbon budget” (total CO2) we have left to burn before we get into the danger zone; according to an editorial that accompanied the paper, “the amount of carbon that humans could emit before Earth warms to that 1.5 C threshold is larger than previously estimated.” Despite howls from the media, Democrats, and climate pimps like Neil DeGrasse Tyson, who last week said it was already too late to recover from man-made climate change, the key goal of the Paris Climate Accord is “not yet a geophysical impossibility . . . we have more breathing space than previously thought.”
