Downstairs, global warming and climate changes are true, I agree, but could you tell me how much the effect of human activities on climate changes? No evidence and data support it.

Increase heat, insect outbreaks, increase wildfires, sea-level rise, coastal flooding, shrinking glaciers, more extreme weather behavior (more storms, heavier rains, hails, frequent snowstorms, etc. Global warming and climate changes are fact and mostly caused by human activities. burning fossil fuels, cutting down the rainforest, forming livestock, greenhouse gas emissions.
For these who are climate change/global warming deniers, you can at least check out this nasa webpage (https://climate.nasa.gov/). It is very easy to read if you have basic English skills. You can then apply your critical thinking skills if any.

In its website, it states the following:
"The Role of Human Activity
In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.
The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 414 parts per million in the last 150 years. The panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50 years."

美国当地时间19日正式重新加入退出107天的《巴黎协定》，美国国务卿布林肯当天发表声明称，《巴黎协定》是“史无前例的全球行动框架”。《美联社》报导指出，世界各国领袖赞扬美国重返巴黎协定，但也希望美国严肃面对过去4年的缺席，并期待未来几个月能够宣布2030年减少的碳排放目标。
联合国秘书长古特瑞斯（António Guterres）表示，美国正式重返这件事“本身就非常重要”，拜登宣布美国将如2009年承诺的那样，继续向较贫穷国家提供气候援助，这一点也很重要。
联合国前气象工作负责人菲格雷斯（Christiana Figueres）表示，这是很重要的政治讯息，人们担心其他国家会跟美国一样，放弃气候变迁工作，但是没有一个国家这么做，美国的城市，州和企业仍在努力减少二氧化碳的排放，不支持的只有联邦政府。
根据CNN报导，白宫任命的气象特使前国务卿凯瑞（John Kerry），在重返巴黎协定扮演了关键作用，总统拜登表示，他与凯瑞以及白宫国家气候顾问麦卡锡（Gina McCarthy）的对话，让他对于重返协定感到鼓舞，他们都是应对气候变迁战争的重要盟友。
