New Study: Burden Of Proof Is On AGW Proponents As Ice Cores ‘Invalidate’ CO2-Driven Climate Change

A French physicist recounts the evidence affirming temperature changes are the cause of changes in atmospheric CO2 concentrations throughout the last 423 thousand years of the ice core record, thus invalidating the claims of more than a negligible role for CO2 in affecting climate changes. In a new study  Dr. Pascal Richet re-emphasizes the “most […]

China finances most coal plants built today – it’s a climate problem and why US-China talks are essential

This story was originally published by The Conversation and is reproduced with permission. You can find the original article here. As nations gear up for a critical year for climate negotiations, it’s become increasingly clear that success may hinge on one question: How soon will China end its reliance on coal and its financing of […]

The Intersections between COVID and Climate Change

https://www.youtube.com/watch?v=uNpAQnaTZX0 The COVID-19 Pandemic has turned most of the world upside down in 2020. COVID-19 related shutdowns have resulted in significant changes in anthropogenic emissions in 2020. We use estimates of COVID-19 mitigation related emissions changes in an Earth System Model to tease out COVID related impacts across timescales, starting with impacts of aviation reductions […]

Atmospheric Electricity, Lightning and Convection

https://www.youtube.com/watch?v=tLaWrofpFoU Benjamin Franklin is considered to be the father of modern-day studies of atmospheric electricity, starting with his famous sentry box experiment in 1749. This clever but risky experiment demonstrated that convective clouds are electrified, yet, even today, there is not a complete theory for how electrified clouds lead to lightning. In this talk I […]

Ocean imprints: Small-scale air-sea interactions and ocean-weather climate connections

https://www.youtube.com/watch?v=TctFCL0fDLk The transfer of energy between the ocean and atmosphere drives global weather patterns and climate variability, as the ocean contains close to 97% of Earth’s water and has absorbed more than 90% of the excess heating in the Earth system. These air-sea interactions are critical to large-scale weather and climate predictions because of the […]

A Machine Learning Approach Toward a “Seamless” Understanding Droughts, Heatwaves and Fire Weather

https://www.youtube.com/watch?v=0d1vBXEURNI The National Earth System Prediction Capability (ESPC) aims to improve earth system prediction from sub-seasonal to decade scales, with emphasis on “seamless” prediction. Yet, our understanding of weather-climate connection, especially in a changing climate, is still in its infancy. For example, it is not clear what weather patterns are responsible for dry spells and […]
