Climate change poses an existential threat to the planet that is no less dire than that posed by North Korea's nuclear ambitions.
Disadvantaged communities are among the most vulnerable to climate change.
China has adopted and is implementing its national climate change program. This includes mandatory national targets for reducing energy intensity and discharge of major pollutants and increasing forest coverage and the share of renewable energy for the period of 2005 through 2010.
As soon as you write about climate change, the first attempt to discredit you is, 'Well, you wrote this on a computer,' or, 'You took a plane to this conference.' So your opinion isn't valid.
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.
You always have to be worried about something that is considered a so-called 'scientific theory' that fits every scenario. Climate change, as they've defined it, can never be disproved.
We've got to keep our eye on what's happening with Russia and North Korea. We cannot lose sight of domestic policy, either. Healthcare. Immigration. Climate change.
Foreign policy is inseparable from domestic policy now. Is terrorism foreign policy or domestic policy? It's both. It's the same with crime, with the economy, climate change.
Look, I'm a huge supporter of Obama's - he's the first president I ever donated money to. But I think in terms of climate change and the environment, he's been, at best, disappointing.
The dialogue around climate change can often become mired in gloom and doom, which is understandable given the topic.
Here in Canada, the people who oppose the tar sands most forcefully are Indigenous people living downstream from the tar sands. They are not opposing it because of climate change - they are opposing it because it poisons their bodies.
I've grown accustomed to hotels and drastic climate change.
More and more Americans are experiencing the direct impacts of climate change, from the wildfires in California, to devastating hurricanes in the Southeast, to drought in the Southwest. And they are choosing candidates who are ready to do something about it.
Opening up Atlantic and Arctic waters to drilling would lock the next generation into burning oil and gas in a way that only makes climate change that much worse, fueling ever rising seas, widening deserts, withering drought, blistering heat, raging storms, wildfires, floods and other hallmarks of climate chaos.
We need healthy forests if we want to protect our climate. As the climate changes, forests become more vulnerable to insect outbreaks, droughts and wildfires. Simultaneously, when our forests are destroyed, their carbon is released back into the atmosphere, further impacting climate change. It's a horrifying one-two punch.
People are seeing the impact of climate change around them in extraordinary patterns of floods and droughts, wildfires, heatwaves and powerful storms.
We won't be able to stop disasters from happening. On the contrary, climate change may increase the frequency and severity of floods, droughts and storms. But we are better equipped today to prepare for them and reduce their impact.
We should not only look at the short-term economic benefits of fossil fuels but also at the bad news for climate change. We should therefore not greet the fossil fuel age unconditionally.
Our economic future and our energy future are one in the same, and it's a future America can't shrink from. We must shape it, just as we've always done. We have to protect our planet from the threat of climate change and ensure that workers have the skills to compete for good middle-class jobs.
By decarbonizing the global economy and limiting climate change, world leaders can unleash a wave of innovation, support the emergence of new industries and jobs, and generate vast economic opportunities.
