The Climate Context
SRM is being considered because of the severe and rising impacts of climate change, alongside insufficient international progress in addressing its human cause: the accumulation of greenhouse gases in the atmosphere.
This page provides the climate context in which SRM is being considered, exploring the role of different climate policies, the main concerns driving SRM discussions, and highlighting issues which SRM would not address, such as ocean acidification.

Every tonne of carbon dioxide (CO2) emitted drives up temperatures and does so almost linearly: if twice as much is emitted, the planet will warm roughly twice as much. This simple rule of thumb is the scientific foundation of today’s climate policy, but could sunlight reflection methods or solar radiation modification (SRM) undermine it?
