金花鼠有排卵为什么不怀孕US President Barack Obama was one of 147 world leaders to address delegates in Paris on 30 November at the opening of the United Nation Conference on Climate Change (COP21). The United States is the world's cond-largest emitter of greenhou gas after China.
Negotiations on the next global agreement on tackling climate change officially started on Monday, with talks presumed to go on until at least 11 December.
Read the full text of Obama's speech below:
President Hollande, Mr. Secretary General, fellow leaders. We have come to Paris to show our resolve.
We offer our condolences to the people of France for the barbaric attacks on this beautiful city. We stand united in solidarity not only to deliver justice to the terrorist network responsible for tho attacks but to protect our people and uphold the enduring values that keep us strong and keep us free. And we salute the people of Paris for insisting this crucial
五大寄生虫conference go on -- an act of defiance that proves nothing will deter us from building the future we want for our children. What greater rejection of tho who would tear down our world than marshaling our best efforts to save it?
Nearly 200 nations have asmbled here this week -- a declaration that for all the challenges we face, the growing threat of climate change could define the contours of this century more dramatically than any other. What should give us hope that this is a turning point, that this is the moment we finally determined we would save our planet, is the fact that our nations share a n of urgency about this challenge and a growing realization that it is within our power to do something about it.
Our understanding of the ways human beings disrupt the climate advances by the day. Fourteen of the fifteen warmest years on record have occurred since the year 2000 -- and 2015 is on pace to be the warmest year of all. No nation -- large or small, wealthy or poor -- is immune to what this means.
This summer, I saw the effects of climate change firsthand in our northernmost state, Alas唇亡齿寒的意思
ka, where the a is already swallowing villages and eroding shorelines; where permafrost thaws and the tundra burns; where glaciers are melting at a pace unprecedented in modern times. And it was a preview of one possible future -- a glimp of our children's fate if the climate keeps changing faster than our efforts to address it. Submerged countries. Abandoned cities. Fields that no longer grow. Political disruptions that trigger new conflict, and even more floods of desperate peoples eking the sanctuary of nations not their own.
That future is not one of strong economies, nor is it one where fragile states can find their footing. That future is one that we have the power to change. Right here. Right now. But only if we ri to this moment. As one of America's governors has said, "We are the first generation to feel the impact of climate change, and the last generation that can do something about it."
炒包心菜I've come here personally, as the leader of the world's largest economy and the cond-largest emitter, to say that the United States of America not only recognizes our role in creating this problem, we embrace our responsibility to do something about it.
Over the last ven years, we've made ambitious investments in clean energy, and ambitious reductions in our carbon emissions. We've multiplied wind power threefold, and solar power more than twentyfold, helping create parts of America where the clean power sources are finally cheaper than dirtier, conventional power. We've invested in energy efficiency in every way imaginable. We've said no to infrastructure that would pull high-carbon fossil fuels from the ground, and we've said yes to the first-ever t of national standards limiting the amount of carbon pollution our power plants can relea into the sky.
The advances we've made have helped drive our economic output to all-time highs, and drive our carbon pollution to its lowest levels in nearly two decades.
白灼虾怎么做But the good news is this is not an American trend alone. Last year, the global economy grew while global carbon emissions from burning fossil fuels stayed flat. And what this means can't be overstated. We have broken the old arguments for inaction. We have proved that strong economic growth and a safer environment no longer have to conflict with one another; they can work in concert with one another.

And that should give us hope. One of the enemies that we'll be fighting at this conference is cynicism, the notion we can't do anything about climate change. Our progress should give us hope during the two weeks -- hope that is rooted in collective action.
Earlier this month in Dubai, after years of delay, the world agreed to work together to cut the super-pollutants known as HFCs. That's progress. Already, prior to Paris, more than 180 countries reprenting nearly 95 percent of global emissions have put forward their own climate targets. That is progress. For our part, America is on track to reach the emissions targets that I t six years ago in Copenhagen -- we will reduce our carbon emissions in the range of 17 percent below 2005 levels by 2020. And that's why, last year, I t a new target: America will reduce our emissions 26 to 28 percent below 2005 levels within 10 years from now.
So our task here in Paris is to turn the achievements into an enduring framework for human progress -- not a stopgap solution, but a long-term strategy that gives the world confidence in a low-carbon future.
