"The budget bill passed today included a lot of extra defense spending. In return for scratching the Republicans’ back, Democrats secured a slew of spending and tax credits on health care, education, and clean energy. Some of these had huge Republican support, such as the 45Q tax credits for carbon capture and 45J nuclear-power production credits."

"Featured prominently in the report is a discussion of a range of techniques for removing carbon dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the world would need to rely significantly on these techniques to avoid increasing Earth's temperatures above 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared to pre-industrial levels."

"While reducing anthropogenic greenhouse gas emissions remains the most essential element of any strategy to manage climate change risk, it is also in principle possible to directly cool the climate by reflecting some sunlight back to space. Such climate engineering approaches include adding aerosols to the stratosphere and marine cloud brightening. Assessing whether these ideas could reduce risk requires a broad, multidisciplinary research effort spanning climate science, social sciences, and governance."

"The world has delayed reducing carbon emissions for so long that humanity will need to suck enormous amounts of carbon dioxide back out from the air to avoid catastrophic global warming. That’s one of the conclusions of a new report published by the Intergovernmental Panel on Climate Change."
