We were aware of it back in the late 1970s. There was a lot of talk about the greenhouse effect. - Joanna Haigh

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.

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.
