Unit 4 Global warming 話題誦讀 日積月累 [導(dǎo)語]　你知道全球變暖會給人類的生活和環(huán)境帶來哪些變化嗎？ Short and Long Term Effects of Global Warming Climate change Global warming is causing the temperature of the earth to rise slowly，causing massive global changes to our natural environment. Rising sea level Global warming is rapidly melting glaciers around the globe，causing a rising sea level and possibly coastal flooding and other weather problems in the future. Ecosystem changes Global warming is changing certain ecosystems throughout due to temperature fluctuations.Animals and plants are being forced to adapt to this，and，as a result，are dying off.
