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
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
Yes. It’s been a while, but we have an update in our Today’s Paradox series: If aerosol climate cooling is underestimated, that means the trend line of the global temperature graph would lie higher than the one you get by … Continue reading
UPDATE: Graph was flawed, but northern hemisphere did breach 2 degrees Just two days ago we had our (‘mildest’/’warmest’/’hottest ever recorded’) winter update, based on the surpassing global temperature records for December, January – and the preliminary data for February. … Continue reading
But not to linger, waiting till tomorrow will cost much, much more:
If we would pump aerosols in the stratosphere to artificially cool the Earth and thereby compensate (part of) the current climate warming, we would be permanently living under a slight sunshade. That would mean in a futuristic world it may … Continue reading
Policy makers find CCS too expensive, climate activists call it an excuse for coal and none of us want it applied in our own backyards. But fortunately science also has a way of silently progressing, as we will be needing … Continue reading
Current practice is to grind and burn enormous amounts of limestone, releasing equally enormous amounts of CO2 to the atmosphere. But isn’t there some way to reverse the chemical process and still end up with building material?
