Observed vs ‘Real’ Global Temperature. What thermometers do & don’t yet show!

After a perceived ‘temperature plateau‘ of about a decade, global temperatures seem to be rising faster than ever before. First 2014 broke the global record for hottest year (then held by 2010). Then 2015 broke that record. And 2016 in … Continue reading

Real Global Temperature Trend, p20 – Combining thermal inertia & carbon cycle inertia: 1 decade extra warming after emissions stop

Apart of course from the amount of greenhouse gases we keep pumping into the atmosphere, there are mainly three factors that determine the amount of warming we will experience in the near future: CO2 climate sensitivity, ocean thermal inertia, and … Continue reading

Real Global Temperature Trend, p18 – Now how high is climate sensitivity? Here’s the answer of the world’s 16 leading climate experts!

If you have any affinity with climate science, this should interest you – probably a lot: Piers Forster, James Hansen, Gavin Schmidt, Alan Robock, Michael Mann, Ken Caldeira, Stefan Rahmstorf, Chris Forest, Gabriele Hegerl, Hans Joachim Schellnhuber, Jonathan Gregory, Drew … Continue reading

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, p9 – ‘Not all Climate Forcers are equal, so Climate Sensitivity is Higher,’ NASA says

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

Real Global Temperature Trend, p8 – Major eruption of Mexican Popocatépetl volcano can cause temporary cooling, 1997 Nature study warned

In our series about the ‘Real’ Global Temperature Trend we’ve learned not to exaggerate the climate cooling potential of volcanoes. That is because many volcanoes are of the wrong type, lie on the wrong latitude – or, the vast majority, … Continue reading

Mistaken headlines due to IEA report. In fact global CO2 emissions reached dramatic new record in 2015. Good news is ‘Energy’, not ‘Climate’

But the problem is, no one is properly measuring. We again point to the Keeling curve – this time NOAA’s ‘global average’ atmospheric CO2 concentration over the last 5 years. Very easy to conclude world media are annoyingly wrong today, … Continue reading

Another shocking climate record: Despite the talk, atmospheric CO2 rise accelerating, never before this fast, carbon feedbacks tip Earth past 404 ppm!

It’s three months since ‘world leaders’ agreed during the climate summit in Paris that climatic warming must be limited to no more than 1.5 degrees Celsius. Yesterday’s news came from Hawaii, where the world’s best annual measurements show that the … Continue reading
