In terms of the impacts of climate change on health when we started 30 years ago, because there was very little data then, so we made suggestions as to what we thought the health outcomes we thought would be affected like vector-borne diseases, crop failures, water availability, sea level rise, increasing disasters related to climatic extreme events, and obviously the effects of extreme heat on vulnerable populations. In particular, elderly people, but not just elderly people. So we suggested a whole range of different health impacts that could occur. And I think, in general, those ideas have stood the test of time, but of course, as the situation has moved on, we've also become much more preoccupied with what kind of action we need to take.

Net-zero is a big idea. It’s a big theme. And, unfortunately, what's going up are many ways to look like you're doing net-zero when you're not. So in the ideal world, getting to net-zero means essentially reducing your emissions, and then, where you have residual emissions left, that means you might need to have negative emissions. For example, it's relatively easy to decarbonize the power sector completely, and you can do it quickly and cheaply in most places, but you’re always going to be left with some levels of emissions from agriculture.
