To fix the climate, we need to change everything. (Seriously.) Luckily, as the recent United Nations climate report shows, we have so many of the technological tools to do just that. From wind turbines to solar panels and heat pumps to e-bikes, there’s so much we can do right now to reduce carbon pollution and get on a more sustainable path. We’ll also need a little innovation along the way — and policies that ensure everyone has access to climate-saving technology and the good life it provides.
