Avoiding Dangerous Climate Change (2005 conference)

In 2005, an international conference titled Avoiding Dangerous Climate Change: A Scientific Symposium on Stabilisation of Greenhouse Gases examined the link between atmospheric greenhouse gas concentration and global warming and its effects. The conference name was derived from Article 2 of the charter for the United Nations Framework Convention on Climate Change The conference explored the possible impacts at different levels of greenhouse gas emissions and how the climate might be stabilized at a desired level. The conference took place under the United Kingdom's presidency of the G8, with the participation of around 200 "internationally renowned" scientists from 30 countries. It was chaired by Dennis Tirpak and hosted by the Hadley Centre for Climate Prediction and Research in Exeter, from 1 February to 3 February. The conference was one of many meetings leading up to the 2015 Paris Agreement, at which the international community agreed to limit global warming to no more than 2 °C in order to have a 50-50 chance of avoiding dangerous climate change. However, a 2018 published study points at a threshold at which temperatures could rise to 4 or 5 degrees through self-reinforcing feedbacks in the climate system, suggesting the threshold (or 'tipping point') is below the 2 degree temperature target.
