Eureka! Gorebal Warming is now not worse than previously thought…

Climate change poses less of an immediate threat to the planet than previously thought because scientists got their modelling wrong, a new study has found. New research by British scientists reveals the world is being polluted and warming up less quickly than 10-year-old forecasts predicted, giving countries more time to get a grip on their carbon output.An unexpected “revolution” in affordable renewable energy has also contributed to the more positive outlook.
Experts now say there is a two-in-three chance of keeping global temperatures within 1.5 degrees above pre-industrial levels, the ultimate goal of the 2015 Paris Agreement.

According to the models used to draw up the agreement, the world ought now to be 1.3 degrees above the mid-19th-Century average, whereas the most recent observations suggest it is actually between 0.9 to 1 degree above.

Published in the journal Nature Geoscience, it suggests that if polluting peaks and then declines to below current levels before 2030 and then continue to drop more sharply, there is a 66 per cent chance of global average temperatures staying below 1.5 degrees.

While they understate the abject failure of the models and idiotically inflate the nonexistent role of “affordable renewable energy” in the failure of the models, it’s a start… About like an alcoholic recognizing that he might have a problem.
Although… This does make me wonder if they might have been sandbagging us. Spending 30 years telling us it’s “worse than previously thought” and that “we have only (fill in the blank) years to save the planet”… To now telling us that, if we only give them more money for climate science and greenschist, we can now save the planet.
Of course… Anyone with an IQ that can’t be counted on two hands already knows that climate change has never been. nor will ever be, “threatening to planet”… (Warning: Lots of F-bombs)…
Limiting global warming to 1.5 °C may still be possible
Analysis suggests that researchers have underestimated how much carbon humanity can emit before reaching this level of warming.

18 September 2017A team of climate scientists has delivered a rare bit of good news: it could be easier than previously thought to limit global warming to 1.5 °C above pre-industrial levels, as called for in the 2015 Paris climate agreement. But even if the team is right — and some researchers are already questioning the conclusions — heroic efforts to curb greenhouse-gas emissions will still be necessary to limit warming.
Published on 18 September in Nature Geoscience1, the analysis focuses in part on the fact that global climate models used in the 2013 report from the Intergovernmental Panel on Climate Change (IPCC) tend to overestimate the extent of warming that has already occurred. After adjusting for that discrepancy and running further models, the authors of the latest study found that the amount of carbon that humanity can emit from 2015 onward while holding temperatures below 1.5 °C is nearly three times greater than estimated by the IPCC — or even larger if there is aggressive action on greenhouse gases beyond carbon dioxide.
