A group of people marching with a sign that reads "Solar power to the people."





Climate change is one of the most challenging problems that humanity has ever faced. 数亿人的生命危在旦夕, 无数的物种和生态系统, 经济的健康和活力, 以及这个星球未来的宜居性.

幸运的是,617888九五至尊娱乐变化是可以解决的. 我们有技术. 我们有617888九五至尊娱乐. 我们现在需要领导,需要改变方向的勇气.

Cut emissions

Carbon dioxide and other heat-trapping gases are the main drivers of global warming. 617888九五至尊娱乐变化无法阻止,但可以减缓.

以避免617888九五至尊娱乐变化的最坏后果, we’ll need to reach “net zero” carbon emissions by 2050 or sooner. Net zero means that, on balance, no more carbon is dumped into the atmosphere than is taken out.

实现净零排放, we need a massive transformation in how we produce and consume electricity. 我们需要更新、更好的交通系统. 我们需要停止砍伐森林. 我们需要一个617888九五至尊娱乐友好型农业系统.

The scale of these changes will require significant federal policy that puts a price on carbon. 它还需要国际合作 巴黎协定, signed in 2016, 反映了迄今为止世界为解决617888九五至尊娱乐变化所做的最大努力, 尽管它不包括我们需要的减排.

Much remains to be done—and we need to do it as quickly as possible.


不管我们减排的速度有多快, 现实是,某些617888九五至尊娱乐影响是不可避免的. 海平面在上升. 气温每年都打破记录.

Droughts, floods, and extreme weather are damaging communities today.

Cutting carbon is the only long-term solution for avoiding climate impacts. 在短期内,我们需要适应. That means everything from discouraging development in high-risk areas, 为水资源短缺做规划, 建设更具弹性的城市和社区. 投资应在617888九五至尊娱乐上合理,在社会上公正, and focused where the impacts are greatest—often in low-income communities and communities of color.


For years, media pundits, 党派智库, and special interest groups funded by fossil fuel companies have raised doubts about the truth of global warming.

These contrarians downplay and distort the evidence of climate change, 游说制定奖励污染者的政策, 并试图降低现有的污染标准.

This barrage of disinformation misleads and confuses the public about the growing consequences of global warming and makes it more difficult to implement the solutions we really need. Until the influence of these special interests is sufficiently diminished, 617888九五至尊娱乐行动将会更加困难.


达到净零排放, we need to do more than just reduce our emissions: we need to actively remove carbon dioxide from the atmosphere or offset its effects.

The easiest way to do this is by planting new forests (afforestation) or restoring old ones (reforestation). 其他加强土地管理的做法也会有所帮助, as can new technologies that suck CO2 out of the air (“direct air capture”), or prevent it from leaving smokestacks (“carbon capture and storage”).

Scale, speed, and cost are the main barriers to all these technologies and approaches. 在美国, strong state- and federal-level policies—and large-scale investment in research and development—are crucial.


The best policy ideas in the world aren’t worth much if we don’t have activists, experts, 每天人们都在为改变而奋斗. From school groups to churches; from corporate boardrooms to mayors and local leaders: we need action.

The Union of Concerned Scientists has worked on global warming solutions for over 30 years. Our experts and activists are campaigning to cut emissions from the energy and transportation sectors; highlighting climate impacts; and fighting for accountability from major fossil fuel companies. You can help.
