The science tells us that if we fail to reduce global warming pollution, global temperatures will rise to dangerous levels and unleash devastating extreme weather events and accelerate destructive sea level rise.

Climate change is real.

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.

There's no question that, um, you know, the oceans have risen, right? And the climate change part is, is a real part of it.

Faced with the evidence, many deniers have started to admit that global warming is real, but argue that humans have little or nothing to do with it.

You want calamities? What about the Ice Age?

Global warming is something that happens to all of us, all at once.
