Global Warming: A Pre-Emergency Report
Global Warming: Fact or Fiction?
Does water (REALLY) freeze when it gets hotter?
Tricky Question? Did you know that salt water will not freeze as easy as warmer non-salty water? Remember that from Science class?
Answer: Warmer (less salty) water DOES Freeze when it is hotter
As deep ocean temperatures around Antarctic rise, they increase ice shelf melt. The meltwater is fresh, or much less salty and dense than surrounding saline ocean layers. Fresher meltwater floats upward, mixing with the cold surface layer, lowering its density. As this fresh layer expands, it forms a stable puddle on top of the ocean that makes it easier to produce and retain sea ice. Read the full story
Alaska gets warmer and drier
Alaska has already warmed by more than 3 degrees Fahrenheit in the past half-century, much more than the continental United States. The consequences have included an annual loss of 75 billion metric tons of ice from its iconic glaciers — including those covering the slopes of Denali, the highest peak in North America Read the full story
Earth’s energy imbalance, which must be eliminated to stabilize climate, provides a crucial metric.
Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 °C global warming is highly dangerous.

A political question? A religious question? A scientific question?
99% of the world’s climate scientists with PhD’s believe it is an undeniable fact. “America is the last developed nation still arguing over all of this.” reported Bill Weir in a Nightline report.
Now we have valid reports coming in:

You have probably heard that the snow pack in the mountains of the western U.S. is disappearing, that glaciers further north are shrinking at breathtaking speed. We hear the aquifers in the West are emptying at unprecedented rates and are sinking. Climate change is bringing this issue to the forefront, but what if this is actually something we could do something about if we had the will?
It turns out we could greatly slow down the pace of the slow motion disaster taking place in front of our eyes. NPR recently reported that decisions made decades ago regarding water usage are dramatically impacting the problem. When the nearby states divided up the Colorado River’s water rights, they miscalculated the amount of water flowing through the river. Rather than dividing up the river so that there would still be some left, as they planned, they actually promised the states more water than existed.
Crops like cotton that have not been economically sustainable for decades without subsidies, and which use far more water than other more useful crops, are being irrigated in the wilderness with water that is only there thanks to the Navajo Generating Station built in the 70’s. In 1972, The Union of Concerned Scientists warned that this producer of electricity would create a “national sacrifice area”. Now we know they were right.
The Navajo Generating Station is our third largest emitter of carbon dioxide, climate warming gases, and a host of other dangerous pollutants. It has created a blanket of haze and smog in the region. The vast majority of the power it generats moves water up 3,000 feet and more than 300 miles to the wilderness in order to water those subsidized crops.
It would take courage, but an immense amount of water could be saved if we would act decisively. Decades could be added to the time we have to find more solutions. A great deal of pollution could be removed as well. It is politically complicated, but should we be asking what the cost of doing nothing will be?
