“人们通常关注年平均温度，这个数值可以给年份排序，但是这种排序经常没有意义”，GISS所长 JamsHansen说道 "热带厄尔尼诺--拉尼娜现象的循环造成了全球气温的巨大年际变化，当把5年或十年的气温平均看，我们就会发现全球变暖的趋势有增无减。"
"When we average temperature over five or ten years to minimise that variability, we find global warming is continuing unabated," Hansen concluded.
虽然其他机制在其后变化中的作用时全球气温升高这一问题复杂化，但这些因素无一能对气温上升作出令人满意的解释。

They concur, though, that climate change is largely to blame: temperatures in the Arctic region have risen at two to three times the global average over the last 40 years.
