Climate alarmists and “settled science” extortionists have a rather incredulous response to a new study appearing in Nature Geoscience. The study takes a fresh look at the “carbon budget,” or how much emissions the earth can take and still maintain endurable temperatures. According to the study, compiled by a consortium of scientists from all over the world, the doomsday clock remains, but it’s been extended by quite some time.

The Washington Post calls the finding “a potential whiplash moment” that “was published by a number of researchers who have been deeply involved in studying the concept, making it all the more unexpected.” According to the study, contrary to previous disquisitions, it is possible to cap global warming at 1.5 degrees Celsius (2.7 degrees Fahrenheit), or what most scientists concur is a critical —but largely out-of-reach — global warming threshold. “It had been widely assumed that this stringent target would prove unachievable,” the Post reports, “but the new study would appear to give us much more time to get our act together if we want to stay below it.”

The Post says that, based on new calculations, “We have more than 700 billion tons left to emit to keep warming within 1.5 degrees Celsius, with a two-thirds probability of success.” According to co-author Richard Millar, “That’s about 20 years at present-day emissions.” The hope is that this buys enough time to more robustly mitigate global warming’s effects. Predictably, however, the study is already being downplayed. But it’s important to understand why the researchers came to this conclusion. For us so-called climate skeptics, it’s not surprising in the least.

According to researcher Joeri Rogelj, “The most complex Earth system models that provided input to [the IPCC] tend to slightly overestimate historical warming, and at the same time underestimate compatible historical CO2 emissions. These two small discrepancies accumulate over time and lead to an [sic] slight underestimation of the remaining carbon budget.” Rogelj’s colleague Pierre Friedlingstein echoed this point: “The models end up with a warming which is larger than the observed warming for the current emissions. … So, therefore, they derive a budget which is much lower.” In other words, the models were too rambunctious.

The problem of overly ambitious global warming projections is well known. Climatologists like Dr. Roy Spencer and John Christy have found that climate models are grossly exaggerating future warming. What’s interesting is that some mainstream scientists are finally — perhaps because the facts leave them with no alternative — addressing this reality. How the rest of their peers are likely to respond is less encouraging. It’s also worth repeating that the true effects of global warming are still unknown and probably excessively dramatized. But at least this study tries to incorporate some authenticity.
