The main issue of cities is to tackle climate change and it is the issue of the current and next generations. Sustainability cannot be emphasized too much and I have designated the issue of climate change as the most important to solve.
The single greatest issue for me as an environmentalist is climate change. I'd have to say that climate change is the single most important issue facing the environmental community and communities as a whole.
It's very important to understand that climate change is not just another issue in this complicated world of proliferating issues. Climate change is THE issue which, unchecked, will swamp all other issues.
Our military leaders have studied the climate change issue and now believe that mitigating climate change is an urgent national security issue.
I don't believe that climate-change fiction will change the mind of a denier because most of the deniers I've met are basically in a cult situation. It's a faith issue. It's not a rational issue. There's no fact that's going to change their mind. They simply believe in the cult of climate-change denial and it somehow feeds into the rest of the mythos of their own life story.
Climate change is not an environmental problem. It is a civilizational problem. Climate change is not just another issue. If it is not addressed in very short order, it will swamp every other issue facing us today
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.
Of course the issue of ending war, and creating prosperity; they're overarching issues all the time. But right now, the challenge to this generation I believe is the climate crisis. It's a national security issue, it's a health issue in terms of clean air, it's a competitiveness issue in terms of innovation and it's a moral issue to preserve the planet for the next generation.
I've done everything I can as a United States Senator to educate myself on the carbon issue and the climate change issue.
I have long understood that climate change is not only an environmental issue - it is a humanitarian, economic, health, and justice issue as well.
Climate change isn't just an environmental issue; it's a technology, water, food, energy, population issue. None of this happens in a vacuum.
We, the present generation, have the responsibility to act as a trustee of the rich natural wealth for the future generations. The issue is not merely about climate change; it is about climate justice.
Obama has acted aggressively on the issue most important to my generation: climate change.
Europe cannot solve this alone. We need stronger U.S. activity on the climate change issue if we are going to move forward. We are trying to do what we can to convince them to be more active on this.
Truly, we do live on a 'water planet.' For us, water is that critical issue that we need. It's the most precious substance on the planet, and it links us to pretty much every environmental issue, including climate change, that we're facing.
The main cause that I have attached my name to and am working diligently in is the issue of climate change.
The trouble with climate change is it's an extraordinarily diverse and complex issue, but for example if the BBC would let me make some of the programmes I'd like to make on climate change, I bet you there would be a change of emphasis.
