Climate sensitivity is hot these days. That is because ‘the lukewarmers’* have tried to suggest it is overestimated – and now real climate scientists are publishing studies showing the opposite: climate sensitivity may be underestimated. Revising equilibrium climate sensitivity upwards, … Continue reading
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
We’ve written about the insane temperature records for January and February 2016 before. But judging by the well-established dataset of NASA’s Goddard Institute for Space Studies – we may have underestimated the extremity of the temperature deviation still:
[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
Okay, disclaimer first: there may be a bit of a climate ego involved in this post. So therefore it is probably best to start with where we were wrong(ish). Based on some rather extensive monitoring of climate models over several … Continue reading
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
El Niño Southern Oscillation index: duration and intensity of La Niña and El Niño years. El Niño is usually defined as a positive temperature anomaly in the east and central tropical Pacific. Another way to express the climate phenomenon is … Continue reading
