Negative Emissions Technologies and Reliable Sequestration: A Research Agenda

What does the scaling-up of negative emissions technologies for environmental law?

In my previous posts , I described how most emissions scenarios that are expected to keep warming within 2 or 1.5°C rely on negative emissions technologies (NETs) at large scales and how the new report from the Intergovernmental Panel on Climate Change addresses NETs (as well as how solar geoengineering could offer an additional means to …

Another Possible Means To Keep Global Warming Within 1.5 Degrees Celsius

Did the IPCC bury the lede regarding solar geoengineering?

In my previous posts on the reports of the Intergovernmental Panel on Climate Change (IPCC), I described how models assume the use of uncertain negative emissions technologies at very large — if not impossible — scales in order to keep global warming within 1.5 or two degrees Celsius (1, 2; see also my colleague Julia …

Negative Emissions Technologies in the New Report on Limiting Global Warming

SR 15 cover

The new Intergovernmental Panel on Climate Change report on 1.5°C warming relies heavily on negative emissions technologies.

Last week, I described how the scenarios expected to keep global warming within the 2°C target, which was internationally endorsed in the Paris Agreement, had to assume the use of negative emissions technologies at very large scales. The Intergovernmental Panel on Climate Change (IPCC), an international assessment body, downplayed this essential fact in its most recent major report, …

A Major Challenge for Avoiding Climate Change Hides In Plain Sight

Bio-energy with carbon capture and storage

If we probably cannot keep global warming within agreed-upon limits by reducing emissions alone, how could we?

Next week, the international body responsible for assessing climate change will release a special report on the 1.5°C target, an ambitious, international goal to limit global warming that became part of the Paris Agreement in 2015. The report might mark a significant turning point for how policy makers, the scientific community, and others think about …
