UN: World Temperatures Rising Faster Than Predicted
The United Nations' World Meteorological Organization says the first half of this year has been the hottest in recorded history.
Scientists say that shows temperatures are rising faster than they expected.
The UN agency warned last week that if temperatures continue rising, 2016 will be hottest year ever recorded.
The agency reported that June was the 14th consecutive month of record high heat for land and oceans. It was also the 378th consecutive month with temperatures above the 20th century average.
David Carlson is with the World Meteorological Organization's climate research program.
"What we've seen so far for the first six months of 2016 is really quite alarming."
UN climate experts say the record heat this year suggests that the Earth can warm up faster than expected in a much shorter time.
Carlson notes that the Earth's Northern Hemisphere -- which includes Alaska, Canada and Russia -- has had unusually warm temperatures.
"I think we're very uncomfortable at how much this surprised us, which might be just a little more cautious way of saying ‘fearful about what happens next.' If we got this much surprise this year, how many more surprises are ahead of us?"
Scientists say carbon dioxide emissions -- which they believe are responsible for rising temperatures -- have also reached new highs.
Doug Parr is the chief scientist at the environmental group Greenpeace.
"What the WMO (scientists) are showing is that temperature is going up along with the increases in carbon dioxide. There's really no doubt that these global warming gases are causing the kind of changes that we're seeing in increased temperatures, threats to the Arctic and threats to the Greenland ice sheet and so on. So there's really no time to waste in getting on and doing something about it."
Representatives of 200 governments will meet in November in Morocco to start enforcing the Paris Agreement. The agreement limits climate change to below 2 degrees Celsius above pre-industrial levels. The goal will not be easy to reach.
Segolene Royal is the French Minister of Ecology, Sustainable Development and Energy.
"We have this moral obligation between the Paris Agreement (reached in December), the 22nd of April signing, and now the November meeting to ensure that at least 55 countries, representing 55 percent of world emissions of greenhouse gases, ratify the Paris agreement."
Some scientists warn that even if that goal is reached in November, it may be too little too late.

Carbon emissions exacerbate the global climate change problem.
Global climate change is also on this year's agenda.

greenhouse gases 温室气体
With the development of economy, more and more greenhouse gases are being discharged into the air.

该组织报告称，截止到6月，陆地和海洋温度已连续14个月刷新历史纪录 。连续378个月超过20世纪平均温度 。

“世界气象组织的科学家表示，随着二氧化碳排放量的不断增加，气温也会逐渐升高 。毫无疑问，因为这些温室气体引起温度升高，进而威胁北极地区和格陵兰岛的冰层 。因此，采取一些必要的措施已迫在眉睫 。”
来自200个国家代表将于11月在摩洛哥会面，开始执行《巴黎协定》 。这一协定限制全球变暖的温度相较工业化之前温度水平增长2摄氏度以下 。这并不是一个简单的任务 。
