Our energy system requires a large transmission network to transport electricity. A clean energy system that does not contribute to climate change will need an even larger one.| MIT Climate Portal
Air pollution, which comes from many of the same sources as the greenhouse gas emissions driving climate change, is one of the largest threats to human health worldwide.| MIT Climate Portal
Net zero emissions are achieved when one's greenhouse gas emissions are effectively balanced out by actions that take or keep greenhouse gases out of the atmosphere.| MIT Climate Portal
Renewable energy is energy from sources, like wind, solar, and hydropower, that we cannot run out of.| MIT Climate Portal
Extreme heat is a dangerous weather condition that is becoming more common and severe as climate change warms the planet.| MIT Climate Portal
Cities concentrate people into small areas for good reason, but this makes them major sources of greenhouse gases and uniquely vulnerable to climate risks.| MIT Climate Portal
Greenhouse gases are gases—like carbon dioxide, methane, and nitrous oxide—that keep the Earth warmer than it would be without them.| MIT Climate Portal
