We must alert and organise the world's people to pressure world leaders to take specific steps to solve the two root causes of our environmental crises - exploding population growth and wasteful consumption of irreplaceable resources. Overconsumption and overpopulation underlie every environmental problem we face today.
Climate change is a complex challenge, and one that will not be easily solved.
Climate change is the biggest governing challenge we face. It's the biggest governing challenge I think we've ever faced.
Global Warming knows no border. It does not discriminate. It affects us all.
Climate change is very real. It is a serious issue it should be treated that way... It is not just ours here in Iowa or even in the United States.
We have carbon in the atmosphere. That is a material in the wrong place problem. It's just like what I said about the lead. Lead in the biosphere is not good. Carbon in the atmosphere (over natural levels) is a problem.
We had global warming between 1940 and 1998. Since then, we haven't had a rise in temperature. That doesn't mean we don't have a problem. If that problem is going to be solved, it ought to be solved by an international treaty.
By looking at climate change as a clean energy generation problem, we're setting ourselves up not to solve it.
Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.
The thing about global warming is that you can address it on a great number of levels - in fact you have to.
Australia has one of the worst mammalian extinction rates in the world.
I always thought we had an environmental problem, but I hadn't realized how urgent it was. James Lovelock writes that by the end of this century there will be one billion people left.
The environment issue is hydra-headed and complicated, but it is of immense importance that we understand how fast the world is changing.
The Chinese have figured out that they have a giant environmental problem. Folks in Beijing, some days, literally can't breathe. Over a million Chinese die prematurely every year because of air pollution.
The problem of the environment is the extension of good housekeeping of the thinking woman.
Can you name an environmental problem that would NOT be easier to solve with fewer people, or harder (and ultimately impossible) with more? Nobody can.
The task of dealing with global warming is urgent and important.
It is one thing to impose drastic measures and harsh economic penalties when an environmental problem is clear-cut and severe...
The more we are using clean energy, renewable energy sources, the less environmentally problematic facilities end up being a problem for everybody, but particularly for folks who have to suffer the consequences of some of these facilities.
Yes, this is hard. But there should be no question that the United States of America is stepping up to the plate. We recognize our role in creating this problem; we embrace our responsibility to combat it. We will do our part, and we will help developing nations do theirs. But we can only succeed in combating climate change if we are joined in this effort by every nation - developed and developing alike. Nobody gets a pass.
Global warming, you don't win it. It's this weird steady-state issue that's going to be with us for a few thousand years.
It is one thing to impose drastic measures and harsh economic penalties when an environmental problem is clear-cut and severe....It is foolish to do so when the problem is largely hypothetical and not substantiated by observations....we do not currently have any convincing evidence or observations of significant climate change from other than natural causes.
