Diary Of The Last Age

Sooner or later, the economic solution to global warming will be adopted, a carbon tax or  dividend .  When this happens beef will become very expensive, available only to the most wealthy.  Removing beef from the diet will have a greater impact on atmospheric carbon dioxide than removing all automobiles.  Rice is going to have a different problem.  People around the world consume rice in their daily diets. But in addition to its nutrient and caloric content, rice can contain small amounts of arsenic , which in large doses is a toxin linked to multiple health conditions and dietary-related cancers. Now researchers at the University of Washington have found that warmer temperatures, at levels expected under most climate change projections, can lead to higher concentrations of arsenic in rice grains. The team will present these findings Dec. 10 at the American Geophysical Union’s Fall Meeting in San Francisco. “In general, the plant is like a big tub...

For several summers, this deeply incised melt channel transported overflow from a large Greenland melt lake to a moulin, a conduit that drains the water through many hundreds of feet to the ice sheet’s bed. (Ian Joughin) I've posted many times about projected increases in sea level.  I believe that will be what really gets people moving on climate change.  It's starting slowly, like a frog in a pot coming to a boil, it might seem okay at first and then suddenly we're cooked.  It's getting worse.   We may be cooked sooner that we realize. The Greenland ice sheet’s losses have accelerated so fast since the 1990s it is now shedding more than seven times as much ice each year, according to 89 scientists who use satellites to study the area. The sheet’s total losses nearly doubled each decade, from 33 billion tons per year in the 1990s to an average now of 254 billion tons annually. Since 1992, nearly 4 trillion tons of Greenland ice have entered the ocean, ...

The goal of IPCC is to keep the global temperature increase from preindustrial times below 1.5 degrees Celsius, however, it's already more than 3 degrees Celsius in Los Angeles and Santa Barbara. It is becoming clear that climate change temperatures are going to affect different parts of the world differently.  Another example is Arctic where the temperatures are increasing faster than anywhere else on the planet.  Here is a diagram showing temperatures around the globe. This shows the Arctic warming but notice the small dot at Los Angeles.  Other places besides the Arctic, are Eastern Europe, Eastern Russia, and off the coast of Uruguay . The entire global ocean is warming, but some parts are changing much faster than others — and the hot spot off Uruguay is one of the fastest. It was first identified by scientists in 2012, but it is still poorly understood and has received virtually no public attention. [A] mysterious blob covers 130,000 square miles o...

A Washington Post analysis of multiple temperature data sets found numerous locations around the globe that have warmed by at least 2 degrees Celsius over the past century. That's a number that scientists and policymakers have identified as a red line if the planet is to avoid catastrophic and irreversible consequences. But in regions large and small, that point has already been reached.  The Post analyzed four data sets, and found: Roughly one-tenth of the globe has already warmed by more than 2 degrees Celsius , when the last five years are compared with the mid- to late 1800s. That's more than five times the size of the United States.
