We are not reaching 1.5ºC earlier than previously thought

Real Climate

On their own, our greenhouse gas emissions would have caused a much higher warming, were it not for the masking effect of aerosol pollution. Similarly, the 1.5ºC goal in the Paris Agreement is not a betting game of where we will end up with maximum temperatures. warmer than pre-industrial times (here defined as 1850-1900).

to 2 o C in line with the goals of the Paris Agreement. They focused specifically on two marine CDR approaches—ocean alkalinity enhancement and biomass cultivation for carbon removal (including seaweed cultivation and sinking) —and two solar radiation management techniques—marine cloud brightening and surface albedo enhancement.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.

Understanding Climate Change & Greenhouse Gas Emissions. The greenhouse effect is a popular name for the earth’s warming effect which occurs naturally when gasses in the atmosphere trap heat from the sun and prevent it from escaping back into space. Greenhouse Gas Emissions are Increasing. We Need to Act Now!

Using Clouds to Fight Climate Change

HumanNature

Scientists used satellite data of ship tracks and climate models to estimate that, globally, changes in low-level clouds due to human-caused (anthropogenic) pollution has a cooling effect that is equivalent to about 25-33% of the anthropogenic warming caused by greenhouse gases , or approximately 1 Watt of energy per square meter.

The ITLOS Advisory Opinion and Marine Geoengineering: More Questions, Few Answers

Law Columbia

The first, known as greenhouse gas (GHG) removal , seeks to mitigate climate change by pulling GHGs – most commonly carbon dioxide – out of the atmosphere and durably storing them. The second category of marine geoengineering activities, known as solar radiation management or modification (SRM), do not directly target GHGs.

Environmental Law: Government and Public Policy Towards the Environment

Environmental Science

For example, the ongoing debate over the impact of certain pesticides in agriculture , greenhouse gas emissions are often a battle between the science and industry's attempts to muddy the science and government lobbying to roll back legislation (2). Typically used in conjunction with “greenhouse gas” but some emissions are not GHGs.
