全球顶级科学家预测，在未来几十年里，暖季将变得更长，冷季将更短，同时极端高温等极端天气将变得更加频繁。联合国政府间气候变化专门委员会发布报告表示，气候变化将加速水循环，在带来更多强降雨、洪涝灾害的同时也会导致许多地区更加严重的干旱。报告作者认为，无论情况如何发展，到2040年，全球升温将达到1.5摄氏度。如果未来几年不大力减排，这一天会来得更早。

The world's leading scientists have projected that in the coming decades, there would be increasing heat waves, longer warm seasons and shorter cold seasons. According to the latest Intergovernmental Panel on Climate Change (IPCC) report, climate change is also intensifying the water cycle, bringing more intense rainfall and associated flooding, as well as more intense drought in many regions. The authors believe that 1.5C will be reached by 2040 in all scenarios. If emissions aren't slashed in the next few years, this will happen even earlier.
