Given the scale of issues like global warming and epidemic disease, we shouldn't underestimate the importance of a can-do attitude to science rather than a can't-afford-it attitude.
My first inclination is to be a bit skeptical about the claims that human-produced carbon dioxide is the direct contributor to global warming.
We have taken the manatees out of the areas in the Caribbean and really elsewhere in the world, and this disruption to the system makes such systems vulnerable to changes as they come by, whether it's in terms of disease or terms or global warming for that matter.
We not only need a rapid transition to a low-carbon economy that prevents the most cataclysmic consequences of global warming, we need real dollars and real planning for coastal protection to combat the consequences that are already inevitable.
Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.
Global warming is real. It is happening today. It is being charted by our satellites. It is being charted by our scientists. It is being charted by those of us in this body, and I think the real key is if we are ready to admit that fact and take the action to make the necessary conversion.
The products built in the factories of G.M., Ford and Chrysler are some of the greatest weapons of mass destruction responsible for global warming and the melting of our polar icecaps.
Many countries - as well as cities, states and provinces - are taking global warming seriously and are working to reduce emissions and shift to cleaner energy sources.
The atmosphere does not fathom whether CO2 comes from U.S. oil or Chinese coal, nor do hurricanes lose force because the Heritage Foundation doesn't believe global warming is a problem. Living systems operate on laws over which we have no say.
Global warming is not a conqueror to kneel before - but a challenge to rise to. A challenge we must rise to.
I would like to see a future where artists think that they have a right to contemplate things like global warming.
Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.
Just imagine how many more cyclists could help save our cities and prevent further global warming by adopting electric bikes, if they received strategic and financial support similar to electric car drivers.
The radical Left loves attacking people as anti-science when anyone dares question their computer models on global warming.
The task of dealing with global warming is urgent and important.
Eighty per cent of global warming comes from livestock and deforestation.
Listen carefully to the global warming alarmists, and the main theme that emerges is that what the developed world needs is a large dose of penance. What's remarkable is the extent to which penance sells among a mostly secular audience. What is there to be penitent about?
On average, global warming is not going to harm the developing world.
I'm saying, Come on, the global warming thing? How did the ice melt during the ice ages? Was the dinosaurs driving SUVs around back then?
Esso has been the main one in America spreading the disinformation that there is no global warming problem.
