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, p6 – THIS is the line you get when you combine ALL (established) temperature measurements

You know about our series by now. We’re investigating the ‘Real Global Temperature Trend‘. That means, as we swim through a turbulent ocean of climate records, we want to maintain a clear view on the horizon – to see where … 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, p4 – If Aerosol Cooling strongly overestimated(?), then Climate Sensitivity is low, says cherry pick study

Several studies suggest global dimming aerosol cooling is not overestimated, but underestimated. But in our quest to uncover ‘The Real Global Temperature Trend‘ – we need to be open for all possibilities – even the bizarrely unsatisfying slap in the … 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

New study: Recent drought eastern Mediterranean (Levant, incl. Syria) worst since Middle Ages, but complicated story

Droughts, or rather ‘air subsidence, hence low precipitation and high evaporation’ belong to the subtropics – therefore much of North Africa and the Middle East is covered by (semi) desert. What is a concern though, is possible further drying due … Continue reading

US climate denial crumbling – Americans that say climate change caused by humans at all-time high

A new Gallup poll shows a couple of very interesting developments. As graphed below the number of Americans that think the witnessed rise in global average temperatures is caused by human pollution has risen to an all-time high, at 65 … Continue reading

#BreakFree2016 – If 6 countries would stop exporting coal, that would be very helpful

Just 6 countries: The United States, Colombia, South Africa, Russia, Indonesia and Australia. If somehow we could sprinkle (perhaps shake) a little common sense, the rest of the world would be deprived of imports of the most polluting and CO2-intensive fossil fuel … Continue reading
