“Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems,” the report says. The final report will be issued after governments and scientists go over the draft line by line in an October conference in Copenhagen.
Depending on circumstances and values, “currently observed impacts might already be considered dangerous,” the report says. It mentions extreme weather and rising sea levels, such as heat waves, flooding and droughts. It even raises, as an earlier report did, the idea that climate change will worsen violent conflicts and refugee problems and could hinder efforts to grow more food. And ocean acidification, which comes from the added carbon absorbed by oceans, will harm marine life, it says.
Without changes in greenhouse gas emissions, “climate change risks are likely to be high or very high by the end of the 21st century,” the report says.
