温室效应英文ppt

heat energy, pass through, glass, heat the ground;
part of the energy, reflect, atmosphere, some, trapped inside;
inside, greenhouse, warmer
❖ The heat energy from the sun passes through the glass and heats the ground.
Greenhouse gases
❖ Carbon dioxide (CO2) ❖ Methane (CH4) ❖ Water vapoutc.
III. Enhanced greenhouse effect
❖ If the greenhouse gases continue to increase, what will happen?

源利用效率。
加强能源管理
建立健全的能源管理制度，加强 对能源消耗的监测和管理，及时
发现和解决能源浪费问题。
发展清洁能源的重要性
减少温室气体排放
清洁能源如太阳能、风能、水能等不会产生温室气体排放， 有助于减缓全球变暖趋势。
促进经济可持续发展
发展清洁能源产业有助于推动经济转型升级，创造更多就 业机会，实现经济可持续发展。
气候变化会对生态系统和生物 多样性产生深远影响，导致一 些物种灭绝，生态系统失衡。

温室效应的影响
对自然环境的影响
气候变暖
温室气体导致地球表面温度升高， 引发气候变化和极端天气事件。
海平面上升
海洋吸收热量并扩张，导致海平面 上升对沿海城市和岛屿构成威胁。
生物多样性减少
气候变化导致生物栖息地减少，对 全球生态系统造成破坏，导致物种 灭绝。
气候变化对全球经济、社会和生态失等。
发展中国家在应对气候变化方面面临资金、技术和能力建设的挑战，需要国际社会 的支持和帮助。
加强国际合作，共同应对气候变化
加强国际气候政策对话与协调，推动 各国在减排、适应、资金和技术等方 面形成共识和行动。

into space; the rest is absorbed by Earth’s system 3. Because of greenhouse gases in the atmosphere, only some of the sun’s energy is allowed to escape immediately—instead, the gases stay within the atmosphere, bouncing in all directions 4. The atmosphere is heated up as less and less gases are let out into space and more energy is absorbed by Earth
CO2 emissions Every ton of coal actually releases 2.86 tons of CO2—how is this possible?
Because coal is compressed carbon—when the carbon gets released,
