At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?
The irony here is this administration is spending more money on climate change research and development than any administration in all the rest of the industrialized world combined.
Climate change should not fundamentally be seen as a political or partisan issue, but it has been turned into a political football primarily by the climate deniers who have a vested interested in maintaining the status quo. That includes certain industrial interests, financial interests and political interests.
After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with climate change. So, I decided to give one talk, and then it snowballed into another talk and eventually to even protesting and getting arrested.
I think Bloomberg's broad vision of the environment in New York City is something I agree with. I broadly stand with his vision for how to deal with climate change and prepare for future weather events.
If we are to candidly and comprehensively address climate change - which I believe is the true crisis of our time - we must find new ways to generate energy and fuel.
We are entering an era of heightened disaster, thanks to climate change. Being prepared for disaster will mean being prepared to sift truth from rumour, and being prepared to adjust our worldview.
Looking at America, which has so much wealth and potential and yet has so many deep-rooted problems, I think it gives us, as Canadians, an opportunity to be on the world stage on the climate change issue.
The effect of climate change is not simply to reduce rain during the summer months, but also to increase the number of torrential storms. When the rain falls that hard and fast, it cannot sink into the ground and go down to the aquifers.
We have to face the reality of climate change. It is arguably the biggest threat we are facing today.
Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.
Climate change is not just about carbon dioxide levels and melting polar ice caps. It is about our public health and protecting our Earth for future generations.
Tragically, no industry has done more to block crucial action to address climate change than the oil industry.
We have changing weather patterns, and we have climate change. This is the science. I hope that my party will come to be comfortable with this because we have to operate in the realm of knowledge and science.
I'm not afraid to spend money on the R&D that's really going to move us to a cleaner energy source that I think is so much the answer to the issues of environmental responsibility and climate change.
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.
The bottom line is clear: Climate change is a reality, and it is having a real impact.
The impact of climate change is a tremendous risk to the security and well-being of our countries.
Climate change is the central environmental ill of our time. We have an obligation to protect our children from the dangers of this widening scourge, and we aren't yet doing enough about it.
On the environment and climate change, I suspect that future generations will think there was too much timidity, too much fear of upsetting business. Basically, New Labour was very nervous about regulating business, or requiring it to do anything, even when there was a very clear social or environmental case for doing so.
The saddest fact of climate change - and the chief reason we should be concerned about finding a proper response - is that the countries it will hit hardest are already among the poorest and most long-suffering.
There are great challenges before you, from the overwhelming nature of climate change to the unfairness of an economy that excludes so many from our collective wealth, and the changes necessary to build a more inclusive and generous Canada. I believe in you.
We have no reason to think that climate change is harmful if you look at the world as a whole. Most places, in fact, are better off being warmer than being colder. And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods.
Beyond the borders of wealthy countries like the United States, in developing countries where most people in the world live, the impacts of climate change are much more deadly, from the growing desertification of Africa to the threats of rising sea levels and the submersion of small island nations.
Climate change is not an excuse to give the federal government ever more power over private property and state resources.
'Years of Living Dangerously' is a wonderful opportunity to reach a lot of people with the story and importance of climate change in our lives; in recent history, there's no bigger threat to the quality of human life than what is taking place right now in respect of climate change.
The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.
Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.
The European nations take climate change very seriously.
For every expert that says humans are the cause of 'climate change' there are 10 more who say we aren't.
I'm a guy that's worked out in the weather since I was 16. I can tell there's climate change. The cause? I'm not smart enough for that.
Companies are the first to see the costs of climate change.
I have long understood that climate change is not only an environmental issue - it is a humanitarian, economic, health, and justice issue as well.
The biggest barrier to dealing with climate change is us: our own attachment to habits that are hard to shift, and our great ability to park or ignore uncomfortable choices.
If we're concerned about climate change as a country, we should have policies that make sure our great-grandchildren have a planet that's healthy and strong.
We are sliding back into a dark era, and there seems little we can do about it. I am profoundly depressed at just how difficult it has become merely to get a realistic conversation started on issues such as climate change or genetically modified organisms.
