The warming trend threatens a state that, in some places, is literally built on ice.
Some insist that the emissions targets will slow the warming trend only slightly.
That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest.

Globally, there is a warming trend of about 0.8C since 1900, more than half of which has occurred since 1979.

Temperature reconstructions have already indicated that the recent warming trend is atypical in the context of the past 2, 000 years.
That's a potential concern of the enhanced melt in west Antarctica if the warming trend we find in summer continues.
BBC: West Antarctic Ice Sheet warming twice earlier estimate
The heavy rainfall accompanies a broad warming trend covering the southeastern United States and reaching into the Midwest, according to the weather service.
That treaty sets limits on so-called greenhouse gases that expires in 2012 and won't do much to stop the warming trend in the atmosphere.
The warming trend means that, every year, there is less old ice and more new ice that has formed in the winter just past.
ECONOMIST: Summer ice in the Arctic Ocean is vanishing rapidly
Do we need companies like Exxon, BP, and Amyris to come up with alternatives to fossil fuels, or are we just over-reacting to a natural warming trend?
Of course decades at the top of that gentle warming trend (of about 0.8 degrees C) are going to be, on average, warmer than those at the bottom.
Yup, there has certainly been a warming trend since then.
FORBES: Gullible Warming: A Contrived Crisis That Is Too Good To Waste
Analyses of the Atlantic, Pacific and Indian oceans show a significant warming trend in tropical areas of the Northern Hemisphere, close to what is known as the thermal equator.
He believes the current warming trend is the result of natural variability, where a planet goes through phases of warming and cooling and the human contribution to it is minimal.
The general warming trend -- 13 of the warmest years have occurred in the 15 years since 1997 -- was highlighted by summer sea ice melt in the Arctic.
The 5 year moving SST temperature average shows that the warming trend peaked in 2003 and a simple regression analysis shows an eight year global SST cooling trend since then .
FORBES: Carbon Dioxide Emissions Up Sharply, Yet Temperatures Are Flat?
Although Greenland has recently been experiencing a slight warming trend, satellite measurements show that the ice cap has been accumulating snow growth at a rate of about 2.1 inches per year.
For example, according to all GCM simulations, increased CO2 concentrations should have produced an increased tropical warming trend with altitude, which is contrary to what balloon and satellites observations actually show.
FORBES: Global Warming? No, Natural, Predictable Climate Change
Rather than abandon the theory, scientists fell back on the notion that the data jibed with the possibility that rising carbon dioxide levels were reinforcing the warming trend in what's called a positive feedback loop.
WSJ: Matt Ridley on Confirmation Bias and Global Warming | Mind & Matter
Clinton is slated to travel to Japan, China, South Korea and Indonesia to discuss a range of issues, including mutual economic recovery, trade, the prevention of nuclear weapons proliferation and reversing the global warming trend.
If those proxies match global temperature measurements, then it would provide independent confirmation of the global warming trend of the past couple of centuries, without being tangled up in some of the difficulties involved in normalizing the measurements.
FORBES: New Study Shows Independent Evidence Of Global Warming
On top of the effects of the warming trend come more frequent and extreme weather events such as droughts, floods and storms which directly cause death and injury and open the door to other serious health problems, according to WWF.
The report blames industrial pollution from the 19th century for climate change from the mid-20th century, although the recent warming trend set in about 20 years ago from the cumulative use of fossil fuels giving off clear greenhouse gases such as methane and carbon dioxide.
Officials with the National Interagency Fire Center in Boise said Wednesday in their first 2013 summer outlook that a dry winter and expected warming trend mean the potential for significant fire activity will be above normal on the West Coast, in the Southwest and portions of Idaho and Montana.
In total, the arctic warming is an unprecedented trend, according to Dr Hinzman.
Clinton also outlined a sweeping agenda of engagement with Asia, ranging from mutual economic recovery and trade to the prevention of nuclear weapons proliferation and reversing the trend of global warming.
"The overall picture of a warming planet with a 'noisy' trend is quite consistent, " he said.
Despite a pretty clear history of warming over the last century, it is even hard to establish any trend in high temperature extremes (in large part because much of the warming has been in warmer night-time lows rather than in daytime highs).
But the law's supporters argue that other places will inevitably regulate greenhouse gases as global warming begins to bite and that Californian businesses will benefit from being in the vanguard of this trend.
