Abstract: Global temperature in the current El Nino exceeds temperature in the prior (2015-16) El Nino by more than the expected warming (0.14°C in 8 years) for the global warming rate since 1970 (0.18°C/decade). Proximate cause of accelerated warming is an increase of Earth’s Energy Imbalance (EEI), but what caused that? Indirect evidence points to a decline in the cooling effect of human-made aerosols. Failure to measure aerosol climate forcing is partly compensated by precise monitoring of EEI details. However, there are no adequate plans to continue even this vital EEI monitoring – which will become even more important as humanity realizes its predicament and the fact that we must cool the planet to avoid disastrous consequences and restore a bright future for young people – let alone plans for adequate aerosol monitoring.
Suspicion that global warming was accelerating was created by the warming rate between the 1997- 98 and 2015-16 El Ninos
The suggestion of reading that much meaning into that little data strikes me as slightly reminiscent of all the talk of a global warming “hiatus” circa 2012, but it does seem like they have more to go on this time. Interesting things are said about aerosols and about NASA.
I wasn’t sure if posting just Dr. Hansen’s profile would be a relevant post here, but if you don’t know who he is I would highly recommend seeking out some of his publications: https://www.columbia.edu/~jeh1/
