问题     The argument that global warming is causing more extreme weather is problematic because it presumes the globe is warming. In fact, the global temperature trend line has been stable for more than a dozen years, while carbon dioxide has increased 7% . If carbon dioxide was the driver, then why have global temperatures stopped increasing?
    Keep in mind that carbon dioxide represents 0. 0395% of the Earth’s atmosphere. Arguing that carbon dioxide is driving the small temperature variations in our climate as opposed to the oceans, which cover 70% of the planet and have 1,000 times the heat capacity of air, or the output of our sun, is scientifically disturbing.
    Weather is more publicized nowadays because of its impact on society and the constant push of the global warming agenda. Increases in population result in more people being in the path of Mother Nature’s great anger. Global warming activists attribute every major weather event to man because they are either uninformed about history, or choose to ignore it. The latest claims resulting from this series of hot and dry summers ignore the fact that more state heat records were set in the 1930s than all other decades of the last century combined. Anyone remember the Dust Bowl?
    Seven major hurricanes hit the East Coast from 1954 to 1960. Now that we are in a pattern similar to the 1950s, the East Coast is vulnerable once again, and attributing events like Hurricane Irene to global warming is incorrect. All the Intergovernmental Panel on Climate Change(IPCC)projections for our climate have proved to be wrong. Global temperatures have stopped increasing and are nowhere near estimates made a decade ago. The IPCC incorrectly predicted Arctic sea ice would disappear by now.
    After Katrina in 2005, more and stronger hurricanes were forecast to be the future. The Accumulated Cyclone Energy Index for the globe has instead declined to the lowest level in 30 years. This does not mean we will not see warm weather and land-falling hurricanes. We are in a pattern similar to the 1950s when U. S. heat and drought as well as East Coast land-falling hurricanes were quite prevalent.
    Perhaps when the Atlantic becomes cold, we will be hearing Ice Age scares again as we did in the 1970s.
Why is it wrong to argue that carbon dioxide drives global warming?
选项 A、Because the sun and the oceans produce much more heat.
B、Because carbon dioxide generates very little heat.
C、Because the air has a smaller heat capacity.
D、Because there are many factors driving global temperature.
答案B
解析 事实细节题。由定位句可知，作者提出了一种观点：二氧化碳推动气候变化从科学角度来说是错误的，因为二氧化碳在大气层中的含量极低，而海洋的热容量和太阳散发的热量远高于空气，因此把仅在空气中占极少一部分的二氧化碳作为推动气候变化的元凶自然是不合理的，故B)“因为二氧化碳产生的热量极少”为本题答案。A)“因为太阳和海洋产生的热量更多”，该选项符合原文，但作者对这方面的介绍的最终目的还是为了证明二氧化碳产生的热量极少，故排除；C)“因为空气的热容量较小”同样也是从侧面证明二氧化碳产热少，故排除；D)“因为存在许多推动全球变暖的因素”没有直接论述二氧化碳，故排除。
