Climate change is the greatest threat to our existence in our short history on this planet. Nobody's going to buy their way out of its effects.
In 2013, I dedicated myself full-time to combating the very real impacts of climate change. Working across the country, NextGen Climate Action formed new coalitions and worked hard to make climate change a part of our national conversation - and across the country, we had a big impact.
The solution to climate change is staring us in the face. It's energy policy. If we pursue a global clean-energy economy, we can cut dramatically the amount of carbon pollution we emit into the atmosphere and prevent the worst impacts of climate change.
The impacts of climate change are not going to get better; they are going to get worse.
Climate change is not going to be prevented. It's not even going to be mitigated to the degree a rational person would want. As a result we're going to have to live with climate change and try to reduce the extent and rate of change as much as possible. This is not an inspiring or sexy project.
I happen to believe that one of the great crises facing the planet is climate change. Donald Trump happens not to think that climate change is real. Hillary Clinton takes it seriously.
We have to have a planet to pass on to the next generation, and these issues of climate change and climate justice and the disproportionate burdens that communities of color actually bear from our damaging climate is a huge issue.
The impacts of climate change are almost immeasurable.
I believe humankind has looked at Climate Change in that same way: as if it were a fiction, happening to someone else’s planet, as if pretending that Climate Change wasn’t real would somehow make it go away.
We can both prevent asteroid impacts and address climate change. It's not either-or.
Attempts to estimate the impacts of climate change continue to be highly speculative.
Climate change has been going on as long as the planet is here, and there will always be a little bit of it.
Despite the international scientific community's consensus on climate change, a small number of critics continue to deny that climate change exists or that humans are causing it. Widely known as climate change "skeptics" or "deniers," these individuals are generally not climate scientists and do not debate the science with the climate scientists.
I believe that the United States has a moral and economic imperative to mitigate the impacts of climate change.
Climates always change. The question is, how are we going to adapt to climate change? Now, it may be true that we are accelerating it inadvertently by messing with our atmosphere, but regardless of that, the climate will change.
There is still time to avoid the worst impacts of climate change, if we take strong action now.
