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.
Much remains to be done—and we need to do it as quickly as possible.
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.
多年来, 媒体专家, 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 617888九五至尊娱乐变化, 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.
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. Investments should be scientifically sound and socially just, and focused where the impacts are greatest—often in low-income communities and communities of color.
The best policy ideas in the world aren’t worth much if we don’t have activists, 专家, 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 专家 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. 你可以帮忙.
