A Quote by Nicholas Stern
We run enormous risks and we know what kind of reductions of greenhouse gases are necessary to drastically reduce risks. Reducing emissions by half by 2050 is roughly in the right ballpark. It would bring us below 550 ppm.

We need to remind ourselves that our ultimate goal is not to reduce greenhouse gases or global warming per se but to improve the quality of life and the environment. We all want to leave the planet in decent shape for our kids. Radically reducing greenhouse gas emissions is not necessarily the best way to achieve that.
If the US is the country that most contributes with greenhouse gases, in the world, it should assume more responsibility to reduce emissions
Governments have to conclude a fair, universal, and binding climate agreement, by which every country commits to reducing emissions of greenhouse gases.
I think that once people understand the great risks that climate change poses, they will naturally want to choose products and services that cause little or no emissions of greenhouse gases, which means 'low-carbon consumption.' This will apply across the board, including electricity, heating, transport and food.
The largest source of greenhouse gases in the coming decades will not be the US, Western Europe and Japan, but the developing economies of East Asia, Latin America and Eastern Europe. The coming eruption of carbon emissions from the poor world will dwarf any reductions in the North.
... the consensus of the scientific community has shifted from skepticism to near-unanimous acceptance of the evidence of an artificial greenhouse effect. Second, while artificial climate change may have some beneficial effects, the odds are we're not going to like it. Third, reducing emissions of greenhouse gases may turn out to be much more practical and affordable than currently assumed.
people who refuse to take risks live with a feeling of dread that is far more severe than what they would feel if they took the risks necessary to make them less helpless - only they don't know it!
Reducing the damage from waste might require expanding the traditional definition of waste - not just as old-fashioned garbage, but as a result of wild inefficiency in all kinds of systems, which often results in emissions of greenhouse gases, among other problems.
When ships reduce their speed they use less fuel, resulting in fewer greenhouse gas emissions and other pollutants; the global shipping industry accounts for nearly 3 percent of global greenhouse gas emissions.
I know we need more nuclear power in order - nuclear power, after all, is not dependent on fossil fuels and emits no greenhouse gases. I believe we're going to be able to have coal-fired plants that have zero emissions. We need to work on carbon sequestration technologies. I mean, there's a lot we can do together and achieve the objective, which a lot of people want, which is the reduction of greenhouse gases, and at the same time, have viable economic growth.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
I compensate for big risks by always doing my homework and being well-prepared. I can take on larger risks by reducing the overall risk.
Diversifying sufficiently among uncorrelated risks can reduce portfolio risk toward zero. But financial engineers should know that's not true of a portfolio of correlated risks.
What we want to do is put a price on greenhouse gases. Because if they're more expensive, businesses will find a way to be more efficient or switch to solar or hydro or wind power. So that will reduce emissions.
You run risks. That's the plain truth. You run risks and, even in the most unlikely places, you are subject to destiny's whims.
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
