Upcoming Developments in International Governance of Marine Carbon Dioxide Removal

Law Columbia

The next week has the potential to bring important developments for international governance of marine carbon dioxide removal (CDR). seaweed) for carbon storage. Solar radiation management is distinct from CDR. In 2022, the parties agreed to evaluate those four approaches, and how they should be governed.

Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

Albedo is the total reflection of incoming solar radiation by Earth. You might be thinking, if the burning of fossil fuels increases Earths albedo due to additional aerosols in the atmosphere, shouldnt this offset any impact from the effects of increased heat-trapping emissions like carbon dioxide? What is albedo?

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but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane.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. ppm, a factor of more than 200 smaller).

Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

The potential collapse of the AMOC—which could happen within this century, or be triggered within this century and play out over a longer timeframe—comes as a result of climate change caused by additional heat-trapping emissions like carbon dioxide in the atmosphere. But what exactly would cause the AMOC to collapse?

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).

There are other things that will get the headlines (the expected time before we get to 1.5ºC or 2ºC, the headline SLR numbers, the ‘unprecedented rate’ statement, constraints on climate sensitivity , carbon cycle feedbacks, the implications for the carbon budgets etc.), 1981) which can be seen here.

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 ”. Callendar’s 1938 paper “The artificial production of carbon dioxide and its influence on temperature” ( Q.
