Global warming will cause China to suffer from dire food and drinking water shortages, with water supply imbalances, severe weather events and rising temperatures, according to a report compiled by Chinese scientists under government supervision. The report projects that the cost of growing food will increase, and that grain production in the country of 1.4 billion will decline between 5 and 20 percent by mid-century. Despite the serious potential consequences of unchecked global warming, the report predicts that China’s greenhouse gas emissions will only begin to decline around 2030, with significant declines not coming until 2050 or so.
China is the the world’s largest overall emitter of greenhouse gases, followed by the U.S., which has a population one-quarter the size of China’s.The U.S. has no national carbon reduction goals, though legislation in California, the Global Warming Solutions Act (AB 32), requires the state to reduce carbon emissions to 1990 levels (427 million metric tons of carbon dioxide equivalent ) by 2020.
In another sign of changing attitudes, the Beijing government has begun posting more accurate measurements of air quality in the capital, following public pressure and a social media effort spearheaded by the U.S. Embassy. For months citizens have been complaining about the disparity between the official air quality measurements and the readings by meters placed by the US Embassy and broadcast via a Twitter account, @BeijingAir (currently with over 17,000 followers.) The government readings will be adjusted to include smaller particles that were not being counted. On some days, the old government measurements touted healthy air quality even while the city was blanketed in smog.
