There is little doubt that Earth is getting warmer and warmer. ___________________________________________________________________________ 2. A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate. ___________________________________________________________________________ 3. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”. ___________________________________________________________________________ 4. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before，so it had to travel greater distances in order to find food. ___________________________________________________________________________ ___________________________________________________________________________ 5. Then what is causing the increase in the global average surface temperature? ___________________________________________________________________________ 6. The heat is released back into space at longer wave lengths. ___________________________________________________________________________ 7. Without this process, Earth could not sustain life. ___________________________________________________________________________ 8. There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide30, not only causing serious damage, but also costing human lives. ___________________________________________________________________________ ___________________________________________________________________________ 9. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay ___________________________________________________________________________ ___________________________________________________________________________ 10. Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. ___________________________________________________________________________ ___________________________________________________________________________ 11. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. ___________________________________________________________________________ 12. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. ___________________________________________________________________________ 13. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. ___________________________________________________________________________ ___________________________________________________________________________ · 课文语法填空 There is little doubt that Earth is getting warmer and warmer.
