Scientists have suggested that in order to avoid further degradation of the climate, emission of greenhouse gasses need to be substantially cut below current levels in the next few decades.
Climate scientists from the UK and US came to this conclusion at an international workshop on the UK AVOID program in Washington, DC exploring the most policy-relevant aspects of understanding dangerous climate change.
Latest results from AVOID have shown that strong mitigation action to limit temperature rise to below 2 degree C avoids many of the climate impacts, but not all of them.
Jason Lowe, chief scientist for the AVOID program, said: "This workshop has provided the opportunity to compare approaches in the UK and US to identify the results that are the most robust. The aim now is to work together to find concrete ways of taking forward the best UK and US science for the benefit of policymakers.
"Such work is essential to inform government policies both in the UK and the US with robust and up-to-date evidence."
Peter Backlund, of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado said "Designing mitigation and adaptation strategies to avoid dangerous climate change is a major challenge for the US, the UK, and other nations."
