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.

What’s the Role of the Land Carbon Sink in Achieving US Climate Goals?

Union of Concerned Scientists

The longevity of naturally occurring carbon sinks, like those in Earth’s forests, is a key part of all modeled and projected pathways to net-zero. Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The problems with the SPM are similar those from the previous fifth assessment report which prompted me to write a post in 2013. 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.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere. Nearly two-thirds of industrial heat-trapping emissions can be traced to just 90 entities.

May 2020 Updates to the Climate Case Charts

Columbia Climate Law

The federal district court for the Northern District of Texas dismissed for lack of standing a lawsuit against the EPA in which an individual pro se plaintiff asserted that EPA restrictions since 1990 on aerosols in the atmosphere had caused global warming. Federal Court Rejected NEPA Claims in Challenge to Gulf of Mexico Leases.
