The Tyndall Centre for Climate Change Research notes that there are no signs of a decrease in global CO2 emissions. Tyndall Centre: Global carbon emissions in 2022 remain at record levels – with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team.…
Ars Technica: New technique shows old temperatures were much hotter than thought. Results imply Earth may be more sensitive to carbon dioxide than previously known. In a paper recently published in Science, Professor Nele Meckler of the University of Bergen and colleagues argue that the climate between around 35 and 60 million years ago may have been…
Nature (February 2022): “Methane levels are growing dangerously fast,” says Euan Nisbet, an Earth scientist at Royal Holloway, University of London, in Egham, UK. The emissions, which seem to have accelerated in the past few years, are a major threat to the world’s goal of limiting global warming to 1.5–2 °C over pre-industrial temperatures, he…
In this brief presentation Professor Rahmstorf explains the most important facts and data on global warming, including from the 2021 IPCC report. Rahmstorf is a leading climate scientist and winner of the American Geophysical Union’s Climate Communication Prize.
NASA: Researchers have found that Earth’s energy imbalance approximately doubled during the 14-year period from 2005 to 2019. Earth’s climate is determined by a delicate balance between how much of the Sun’s radiative energy is absorbed in the atmosphere and at the surface and how much thermal infrared radiation Earth emits to space. A positive…
Robert Howarth talks with Dan Miller about natural gas (methane) and coal in terms what these fossil energies hold for our climate. Robert Howarth is Professor of Ecology & Environmental Biology at Cornell University. He is an expert on natural gas & methane and their impact on the climate. In this wide-ranging interview, Prof. Howarth…
The 2021 published study Non-Monotonic Response of the Climate System to Abrupt CO2 Forcing (10.1029/2020GL090861) involves research from the Department of Applied Physics and Applied Mathematics, NASA Goddard Institute for Space Studies, Center for Climate System Research, and the Lamont-Doherty Earth Observatory. The study key points are: We examine the response of the climate system…
An international team of scientists, from Texas A&M University, the University of Southampton and the Swiss University ETH Zürich, led by the University of St Andrews, published their findings in the study, Atmospheric CO2 over the Past 66 Million Years from Marine Archives. The international team pulled together data collected over the last 15 years using high-tech laboratory techniques. The combined data spans the…
Climate scientist James Hansen in his latest blog, Fighting the Battles, Winning the War – once again reminds us of the carbon fee-and-dividend. And that President Joe Biden has the authority to bring it forward. Meanwhile, Canada already has a carbon fee-and-dividend, with British Columbia operating a system very similar to Fee and Dividend, as…
