“现代气候预测主要基于气候模式和物理机制诊断相结合的办法。”国家气候中心主任宋连春介绍，经过近半个世纪的发展，目前国内外气候模式对气候系统的模拟、刻画已经比较全面。 地球的气候系统由海洋、陆地、大气、冰冻圈、生物圈这五大圈层构成，非常复杂。气候模式可以说是对气候系统的数学表达，科学家编写反映很多数理方程原理的复杂程序，再通过超级计算机进行运算，对未来的气候演变趋势作出预测。气候模式要用的数据量大...

Things for the administration >> on the environmental side, this disregard of science, they're gutting science cross the agencies, cross the departments, cross the government. >> even if scientists are advising you, mr. president, this is very dangerous to the environment, to the fisheries, to the state of alaska, if the president decides that's the decision. >> that's the decision. >> reporter: and the only recourse is for environmental groups to sue. >> you'll have a host of lawsuits. i'm convinced. >> >> reporter: alaska's governor is a huge trump supporter. he's met with his several times....
Huge mine. in 2017, president trump's first epa administrator scott pruitt canceled the meetings. pruitt backed down and put the protections back in place. now, another private meeting, this time with the president himself has led to yet another win for the mine and removal of environmental protections for this pristine watershed. >> on the environmental side, this disregard of science, they're gutting science cross the agencies, cross the departments, cross the government. >> even if scientists are advising you, mr. president, this is very dangerous to the environment, to the fisheries, to th...
