Weeks of what will likely be the warmest year on record in a city still on edge from last months terror attacks. At the eiffel tower today, police allowed a protest from environmentalists who say the deal doesnt go far enough. At the white house this evening, president obama said the agreement could be a turning point for the world. Heres mark phillips. Reporter it took a day longer than planned and the intent of the deal still has to be turned into action, but when French Foreign minister Laurent Fabius brought down his gavel, cheers and applause it confirmed there was a long elusive deal to limit how much the earth will be allowed to heat up. Delegates can be up the past two nights pulling the deal together, and it had taken some arm twisting, not least by u. S. Secretary of state john kerry. Its a victory for all of the planet and for future generations. Reporter it will take decades for the effect of this deal to take effect, and many like the floods that hit areas of england this past week, are still likely. But the provisions of the deal are ambitious. It calls for the global average temperature rise to be held at less than two degrees celsius above preindustrial levels, forever. Thats 3. 6 degrees fahrenheit, and even says the rise should ideally be even lower than that. The deal, once ratified, would be legally binding. And it would establish 100 billion fund under which rich countries would help poorer ones cope with the consequences of climate change, like these floods. This is supposed to be the road. The lake is supposed to end over there. They built special flood defenses here the last time this happened. Good, they said, for the 100 year event, but, clearly, they havent coped, and that last flood was just six years ago. But the significance of this t deal is that both rich and poor has to be done, even if theres no clear agreement on exactly how to do it. The new deal will not of itself end global warming. The pledges most countries have made to cut their Carbon Emissions will not keep that warming to the limits with which the world can cope. But, jim, this deal is being seen as a turning point with the whole world now agreed on what must be done, and thats something. Axelrod mark, thank you. Tonight the western u. S.

Well, were taking a look at the latest storm to move into the northwest here, and more heavy rainfall. Its the wettest start to december ever recorded in seattle and portland but this storm is a little bit different, it has more cold air to work with. Were expecting over a foot of snow on top of that rain, around the cascades, the sierras and the bitterroot, so much more widespread snow and winter storm now out ahead of it, the storm system in the plains, producing Severe Weather tonight. So were watching texas into oklahoma, damaging wind gusts, heavy rainfall, many areas here on track for their wettest year on record and then its the heat. Everywhere in the east, unbelievable record highs in many cities today, dozens of them. Were expecting more heading into sunday.

The two have played nice during the campaign but not so nice since these off help camera comments came out this week. The New York Times obtained raiser saying he was the electable conservative who could take on the establishment, not trump or ben carson. Reporter today, trump acknowledged the gloves are coming off. Weve had a very Good Relationship but im sure it will end because, you know, hes got to come after me at some point. Reporter still, wary of alienating trump supporters, cruz held his fire, tweeting tonights bloomberg poll shows Iowa Republicans think trump has a slightly better chance of beating hillary clinton. Jim, in an interview with fox news, before that poll was released trump had a message for Republican Leaders about his frontrunner status. He said, youve got to get used to it.
