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

Graph of the day: Arctic has warmest winter on record

Usually winter climate news from the Arctic comes somewhere in March, at the turning point of seasons, when we can precisely compare the annual sea ice maximum to that of other years. But this year we know it’s gonna be … Continue reading

Graph shows countries urgently need to strengthen 2030 emission targets before Paris climate summit – emissions gap >19Gt CO2

Today’s Graph of the Day has a really sobering message. Within four months of the crucial UNFCCC climate conference in Paris (‘COP21′) countries have submitted grossly insufficient emission reduction targets for the year 2030 – the target year for the … Continue reading

The world temperature ‘plateau graph’ that the 2014-2015 El Niño will break

This is the graph of the world’s best-established temperature dataset, of NASA GISS. It shows another good representation of the 1997-1998 El Niño world average temperature peak. Recent years have been net influenced by La Niña state, as shown in … Continue reading
