Geoengineering may be used to combat global warming, experts say

IPCC authors suggest there is high agreement that injection of chemicals into stratosphere could help limit rises — The world may increasingly look to geoengineering in the wake of the latest UN climate report, which says it could be adopted as a temporary “remedial measure” if the world heads towards dangerous levels of warming. The …

Q&A: How ‘integrated assessment models’ are used to study climate change

Working out the best ways to tackle climate change is one of the key challenges facing policymakers both today and in the decades ahead — To inform these decisions, scientists and economists have developed a suite of tools known as “integrated assessment models” (IAMs). These models are used to answer central questions about climate change, …

New study finds incredibly high carbon pollution costs – especially for the US and India

As a wealthy, warm country, the US would benefit from implementing a carbon tax to slow global warming — The social cost of carbon is a measure of the economic damages caused (via climate change) by each ton of carbon pollution that we produce today. It’s difficult to estimate because of physical, economic, and ethical …

World must act quickly to govern solar geoengineering, report says

Actions to manage solar geoengineering must “begin now”, says a report by an international group of governance experts — The idea of solar geoengineering – a set of hypothetical technologies that would lower global warming by reflecting sunlight away from Earth – cannot be “wished away nor delegated to technicians”, according to the group. Instead, …
