“Beyond 1.5C would put peace, security, economic stability and nature in peril across our planet and be an existential threat for far too many.” “People around the world are already suffering from the impacts of climate change at 1.1C of warming,” said Emily Shuckburgh, director of Cambridge Zero at the University of Cambridge. Mental health challenges, including anxiety and stress, are predicted to increase alongside humans’ exposure to extreme weather, and climate change is already “contributing to humanitarian crises”.Ĭlimate impacts will “s ignificantly increase ill health and premature deaths” in both the near and long term, the report predicts. Heightened risk of cardiovascular illness due to exposure to smoke from wildfires has been observed, and an additional 2.25 billion people will be at risk of Dengue fever by 2080 under a middle-of-the-road emissions scenario. Extreme weather has already pushed millions more people into food insecurity as climactic changes increases the likelihood of simultaneous crop failures even as staple foodstuffs are losing nutritional value. Here are five key messages from the landmark report.Ĭlimate change is already damaging the physical and mental health of everyone on Earth, with half of humanity already vulnerable to water insecurity and billions more at risk of extreme heat events, vector-borne diseases and hunger linked to global heating.Įxtreme heat in particular has resulted in increased human mortality and morbidity, and it is projected to worsen as the century progresses.įlooding has led to increased displacement in Asia, Africa and Central America and is predicted to increase. Next month will see WGIII release its assessment of how to avoid the worst case warming scenarios. Monday’s Working Group II (WGII) is the second installment of the IPCC’s sixth assessment report (AR6), following the release last August of WGI, which reviewed the underlying physical science of climate change. It is the first such assessment from the Intergovernmental Panel on Climate Change (IPCC) since 2014 and reflects large advances in scientific understanding of the effect global heating is having on us all. The UN’s climate science body today released a major report on the impacts that climate change will have on humans and the planet, and how we may adapt to them.
