Real Global Temperature Trend, p10 – Refining cloud feedbacks lifts climate sensitivity to 5-5.3 degrees(!), say Yale researchers

Climate models have falsely assumed a (strong) cloud brightening cooling feedback, researchers of Yale University (Ivy Tan & Trude Storelvmo) and the Lawrence Livermore National Laboratory (Mark Zelinka) write in Science. Refining cloud behaviour in a warming atmosphere leads to … Continue reading

Real Global Temperature Trend, p7 – ‘Volcanoes did not cool the Earth in the 1980s, so Climate Sensitivity at least 2.1 to 8.9 degrees Celsius’

Even if you assume a low value for the variables of SO2 cooling and the rate of heat uptake by the deep ocean. Yes, that caught our eyes too. “Studies of these [volcanic eruptions and El Niño] effects using climate models … Continue reading

Real Global Temperature Trend, p5 – Climate Sensitivity higher when models include subtropical cloud-decrease feedback

We could say clouds are too complicated for climate science – and ignore them forever. We could also just try to incorporate them in the models. If you do, chance is you’ll find climate sensitivity is underestimated, a very interesting … Continue reading

Real Global Temperature Trend, part 3 – Global Dimming declining, but could still mask 50 percent of CO2 warming(!)

Amidst a storm of climate records here at Bits of Science we’re searching for ‘The Real Global Temperature Trend’. Today is part three of the series – the second episode about ‘Global Dimming‘. Although worldwide aerosol pollution is slowly declining … Continue reading

Searching for Real Global Temperature Trend amidst storm of climate records, part 1 – Likelihood: “99.9999%” there IS a trend

It’s 2016 now and 2016 is becoming a whole different story than 2015, that in turn was a whole different story than 2014. But still, also heat-record-breaking 2014 remains an interesting case – as that year broke the then-proclaimed temperature … Continue reading

Important update: Here is why crazy February temperature record is NOT the result of El Niño

Yesterday we pointed out that it is odd that it is actually the NASA GISS temperature dataset that shows the largest temperature anomaly for February 2016, namely 1.35 degrees Celsius above the 1955-1980 baseline. Indeed, a monthly deviation that really … Continue reading

Graph of the Day: World has warmest winter on record

[Not just the Arctic experiences the warmest winter on record – this goes for the entire globe, new NASA data show. We now have the hottest winter on record straight after the hottest summer on record.] Just when you thought positive global … Continue reading
