The unconventional scientist who predicted that rising carbon dioxide levels would change the climate

Physics World

In fact, in 1938 Sir George Simpson, a leading meteorologist, dismissed the link between rising carbon-dioxide (CO 2 ) concentration and temperature as “ rather a coincidence ”. The non-expert in question was Guy Callendar , a British steam engineer doing his own atmospheric research at home.

The Fossil Fuel Industry Continues Producing Heat-Trapping Emissions that Drive Climate Change

Union of Concerned Scientists

The InfluenceMap dataset includes company-by-company data on emissions of carbon dioxide–the heat-trapping gas responsible for the largest contribution to climate change–and methane, a very potent heat-trapping gas that lasts a shorter time in the atmosphere.

The definitive CO2/CH4 comparison post

Real Climate

but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. Thus despite the smaller concentrations and changes in methane compared to carbon dioxide, the impacts are comparable. W/m 2 for CH 4. Stocks and flows.

2023 confirmed as the warmest year ever recorded

A Greener Life

degrees Celsius warmer than in the 1850-1900 pre-industrial period, when humans began burning fossil fuels on an industrial scale, pumping carbon dioxide into the atmosphere. The Copernicus Climate Change Service added, that in 2023 the concentration of CO2 in the atmosphere rose to the highest level ever recorded at 419 PPM.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

Something Stinks: California Must End Manure Biomethane Accounting Gimmicks in its Low Carbon Fuel Standard

Union of Concerned Scientists

Each credit one metric ton of carbon dioxide equivalent pollution below the standard. I’ve written recently about why a Cap on Vegetable Oil-Based Fuels Will Stabilize and Strengthen California’s Low Carbon Fuel Standard , which addresses the bio-based diesel credits.
