9、TIONWc have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.In 2013, a lot of people were sho

11、, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant that the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on E

17、imate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our carbon footprint by restricting （he amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global wanning, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet.
