If we are ever to halt climate change and conserve land, water and other resources, not to mention reduce animal suffering, we must celebrate Earth Day every day - at every meal.
I would point out that if you're a believer in the Bible, one would have to say the Great Flood is an example of climate change and that certainly wasn't because mankind had overdeveloped hydrocarbon energy.
Being at NASA and having the access to both computing capability and satellite observation capability is kind of the ideal research situation to try to understand global climate change.
I want to use my position of leadership to help move along at a faster pace what I believe and know the Obama administration wants to do around the urgency of climate change.
A 501(c)3 can't lobby. A 501(c)3 can't invest in a company or build an industry. It may be that the only way to deal with climate change is to create an industry or build companies.
Homes and buildings, many of which are old and drafty, eat up 40 percent of the energy America uses. Such inefficiencies perpetuate our reliance on foreign oil, imperiling our national security and increasing our contribution to climate change.
I sort of feel that climate change will be solved by science. I just feel instinctively that we will find a way of saving ourselves. But I am less confident that we won't destroy ourselves in other ways.
Black Saturday reminded many Australians of what they know only too well: that of all the advanced economies, Australia is perhaps the one most vulnerable to climate change.
A Labor prime minister, Julia Gillard, who does believe in climate change, nevertheless advised her predecessor, Kevin Rudd, to abandon his emissions trading scheme.
In fact, even the current administration now is releasing recent reports indicating that climate change is real, that global warming is occurring, that it is heavily influenced by man-made objects and that it is something we cannot ignore any longer.
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.
In Congress, I am focused on the effects of climate change, including ocean acidification and sea-level rise - both of which are threats to healthy oceans that sustain life on- and off-shore.
Climate change could produce a lot of misery and waste without necessarily leading to large-scale armed conflict, which depends more on ideology and bad governance than on resource scarcity.
The doomsayers of the 1970s were wrong about how quickly the world would run out of oil, but not about the dangers that hydrocarbon consumption posed to the global environment, especially with respect to climate change.
If the movie had ended in Hollywood fashion, the Copenhagen climate conference in 2009 would have marked the culmination of the global fight to slow a changing climate.
I began to think that there was a place for 'Footloose' to get retold again, that there was actually a more conducive political climate, an emotional climate to explore a town that has experienced a trauma and a shock, and starts overreacting.
Nature shrinks as capital grows. The growth of the market cannot solve the very crisis it creates.
The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.
If we deny climate change and don’t care about environmental degradation; we are no more than those people who are willing to be stupid because someone else was stupid in the past.
Climate change. Urbanization. Biotechnology. Those three narratives, still taking shape, are developing a long arc likely to dominate this century.
For reasons we don't have to get into, climate change has become an incredibly polarized issue in the United States. I think that is sad. My own personal view is that we're in a planetary emergency such has not been seen in 600,000 years.
