“The climate system takes decades to respond to changes in carbon emissions so decisions made now will affect future generations - for better or worse.”
“Without concerted and swift international action to reduce emissions of greenhouse gases, the 1.5°C threshold is likely to be passed by 2040 and the report () sets out very starkly the costs of inaction.”
“We were aware of it back in the late 1970s. There was a lot of talk about the greenhouse effect.”
“I think it’s going to be very, very, very difficult to get to 1.5C.”
“Solar geoengineering, I’m afraid I think it’s a fool’s paradise, and I’ve been saying the same thing for many years.”
“I think it is possible to get the carbon dioxide emissions down and to get the temperature increase slowed down. It just requires everybody to work together to do it.”
