Real Global Temperature Trend, p17 – Climate System Thermal Inertia is lower when you don’t assume CO2 flatline

Oceans, oceans, oceans. You thought the atmosphere was complex? Well, just take a look at the oceans. Oddly shaped features with disturbing cycles and conveyor belt currents. Home of the octopus, the blue whale and a Mariana Trench full of … Continue reading

Real Global Temperature Trend, p16 – Climate System Thermal Inertia: Trend Line = 0.6C higher than observed temperatures show

In part 16 of our temperature trend series we take a better look at one of the main reasons almost everyone still underestimates climate urgency: ‘Thermal inertia’ of the climate system – a delay between the moment of emissions of … Continue reading

Real Global Temperature Trend, p12 – March breaks February record, says JMA. Have +1C peaks become new monthly norm?

We knew that in early March the northern hemisphere broke the 2 degrees pre-industrial temperature limit. We did not expect it would also break February’s global record. But it did. According to the Japan Meteorological Agency (JMA) that ‘insane temperature … 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

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
