Tonga Eruption Blast Increased Atmospheric Water Vapor by 10%

NASA: The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The…

Methane levels are growing dangerously fast

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…

Earth’s Energy Imbalance Has Doubled since 2005

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…

Natural Gas vs Coal, and what does it mean for the Climate?

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…

Study: Non-Monotonic Response of the Climate System to Abrupt CO2 Forcing

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…

New study finds CO2 today enough to raise sea level by 20 metres

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…

Will President Biden bring forward the carbon fee-and-dividend?

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…
