Circle of Blue

Scientists estimate that Brazil hasn’t seen a normal period of rainfall since 2010. Scientists estimate that the country hasn’t seen a normal period of rainfall since 2010. The country’s worst drought in nearly a century is choking commerce, threatening ecosystems, and diminishing hydroelectric power generation. Wikimedia Commons.

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).

The Latest IPCC Report — How Are We Doing on Mitigation?

Law and Environment

I suspect that, if one asked the average American whether GHG emissions increased or decreased from 2010 to 2019, they would say that emissions decreased. GHG emissions in 2019 were 12% higher in 2019 than 2010. We’re almost certainly going to have to spend money pulling carbon from the atmosphere. Sadly, that’s not the case.

NASA selects two Venus missions for launch

Physics World

NASA has announced it will send two missions to Venus to study the planet’s atmosphere and geological features. The Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging Plus (DAVINCI+), meanwhile, will be a probe that will dive through Venus’ atmosphere to precisely measure its composition down to the surface.

‘This shouldn’t be happening’: levels of banned CFCs rising

Environmental News Bits

The Montreal Protocol, which banned most uses of ozone-destroying chemicals known as chlorofluorocarbons (CFCs) and called for their global phase-out by 2010, has been a great success story: Earth’s ozone layer is projected to recover by the 2060s.

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.
