问题    It has become a recurring theme, and worryingly so. Since October 2015, our planet has experienced ten consecutive months of human-influenced, record-breaking temperature increases. The previous October, November, December, January, February, March, April, May and June months were all documented as the warmest Octobers, the warmest Januarys, the warmest Aprils; global heat highs are the hot new trend and the data suggests they are here to stay.
   According to NASA, July 2016 is not only the warmest July in history, but the warmest month in recorded history. NASA has tallied temperature changes from 1880 to the present day, with its data showing no signs of a slow-up in rising temperatures. Climate scientists have been perplexed in their attempts to understand the factors pushing the mercury so far up the thermometer this year. El Nino—the phenomenon explaining the unusual warming of surface waters in the east-central zone of the Pacific Ocean—has been tied to increased ocean water temperatures and changes in weather patterns.
   Important as it is to factor El Nino into the climate change framework, it is highly unlikely that it has contributed significantly to the hurried, upward trend witnessed these past ten months. If anything, focus on the subsiding effects of El Nino risks detracting attention from the pressure asserted on the climate by human activity.
   Greenhouse gases continue to bloat the atmosphere, trapping heat as atmospheric escape routes are obscured. Further exacerbating the climate change panic seems to be an unusually high temperature currently being experienced in the Arctic region. Arctic sea ice is the most vulnerable to climate change, and is now at a new low with ice cover down to 14. 54m sq km.
   With no clear solution in sight, the ice is destined to continue melting, with longer melting seasons becoming a normal occurrence. The U. S. National Oceanographic and Atmospheric Administration have noted a similar trend for the past 14 months, and are expected to release a similar figure for July. Though the rise is expected to taper off towards the end of the year, a scientist drew attention to how there is a "99 percent chance of a new annual record in 2016". As we confront the reality that many of these changes are as a direct consequence of human intervention, it is very possible that without the appropriate response, we could be contending with broken records for years to come.  
According to the passage, El Nino has had an impact on______.
选项 A、the rising temperatures in the past ten months
B、diverting our attention away from human activity
C、dramatically increasing our environmental awareness
D、reminding people to factor it into climate change
答案B
解析 细节题。答案定位于第三段第二句“如果说有推波助澜的嫌疑的话，那就是对厄尔尼诺逐渐减弱的效应的关注转移了对人类活动给气候所造成的压力的关注”。四个选项的意思分别为[A]“最近10个月的气温上升”；[B]“转移我们对人类活动的关注”；[C]“大幅度提高我们的环保意识”;[D]“提醒人们考虑厄尔尼诺对气候的影响”。
