The Intergovernmental Panel on Climate Change released a report stating that the world is quickly running out of time to keep global warming below 1.5 degrees Celsius. To get there, the world would have to cut current emissions by 45 percent by 2030. That sounds absurdly unlikely. But before we give in to despair, we should remember that the technology to address climate change is going along at high speed. The largest source of U.S. carbon emissions is transportation, and a Green New Deal for motor vehicles would be quite straightforward. The reason is simple: With some subsidies( 补贴 ), electric cars and buses are now cost- competitive with fossil-fuel vehicles. Electric buses have made the greatest speed into the market, because they are a logical choice for electrification. By the end of 2018, electric vehicles were displacing(取代) about 280,000 barrels(桶) of oil demand per day—about 84 percent of which was due to buses. But the electric car market is also reaching maturity, with appealing designs, longer range, and a quickly-expanding rapid charging network in many countries. It's worth emphasizing that most of the infrastructure( 基础设施 )necessary to recharge electric vehicles already exists. People often tend to assume that we would need to replace every gas station, but virtually(差不多)all homes and businesses already have an electrical connection which can be easily improved for fast charging. All that is needed to go fully electric is enough battery capacity and fast charging stations to deal with long trips. Now America would have to repair its electricity production, freight rail(货运铁路), shipping, and so on to fully decarbonizes( 脱碳 )the transportation sector, which taken together will be considerably more difficult than simply extirpating fossil fuel vehicles from the market. But greening America's vehicle would be straightforward, relatively cheap, and a huge stride(一步,进展) forward on climate. The politics of climate change are so fearful that despair can seem logical, but the first step to achieving a tough goal is the confident belief that it can be done. And this particular step wouldn't even be that tough. 1. How’s the goal of keeping global warming below 1.5 Celsius according to Paragraph 1? A. Reasonable. B. Safe. C. Realistic. D. Impossible. 2.
