The first climate change presentation I saw was back in the 1970s when I was working for the National Weather Service. Murray Mitchell, was the top climate scientist for NWS. While that got the bulk of the publicity, Dr. Mitchell assured us that the warming of the climate would be the biggest problem in the future.

In an unchanging climate, the random fluctuations would lead to warming in some parts of the world and cooling in others. In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling.

Last week, the Nobel physics prize was (half) awarded to Suki Manabe and Klaus Hasselmann for their work on climate prediction and the detection and attribution of climate change. This came as quite a surprise to the climate community – though it was welcomed warmly. But let’s go back to the beginning.

I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on Climate Change (IPCC) on August 9th. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Several floating ice shelves – the massive slabs of ice that push back grounded ice from flowing into the ocean – have catastrophically broken up in a matter of days because of such melting.

Long term, climate change is a greater threat than the COVID-19 pandemic. An area of high pressure above the Pacific Ocean was driven eastwards through the jet stream by a “Rossby wave” – a planetary-scale fluctuation arising from the Coriolis force. Where are they most likely? How extreme might such occurrences be?

Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
