Latest Climate Chane Report From IPCC

The IPCC has just published its latest report on climate change. It details the impacts, adaptation, and vulnerability associated with climate change. An example of this would be the risk associated with food insecurity due to more intense droughts, floods, and heat waves in a warmer world, especially for poorer countries.

What strikes me as ironic about the food shortage issue is this is the exact same outcome seen by conservatives as a result of our federal government's mishandling of our economy. I got to hear about it all weekend at a recent family gathering from my brother in law who is basically inconsolable. "Our children's futures are being mortgaged away" he cried many times yet the very real danger presented by climate change bounced off the bubble. "Liberal propaganda...liberal plot to control us..." were words I heard any time the subject came up.

It's not just climate change, though. They have no concern whatsoever about the abuse of power of corporations, our dilapidated infrastructure, the inability of parents to think globally in terms of our education system or our health care know, the ACTUAL problems we have as opposed to the phantom menaces they make up (actually it's only one menace...the federal government).

So, why do conservatives worry about things that aren't likely to happen and go completely limp when it comes to things that likely will happen?

IPCC Report Findings

The IPCC released its fifth assessment yesterday and, as expected, found that it is extremely likely (95 percent) that humans are causing climate change. It's key findings:

— Global warming is "unequivocal," and since the 1950's it's "extremely likely" that human activities have been the dominant cause of the temperature rise.

— Concentrations of CO2 and other greenhouse gases in the atmosphere have increased to levels that are unprecedented in at least 800,000 years. The burning of fossil fuels is the main reason behind a 40 percent increase in C02 concentrations since the industrial revolution.

 — Global temperatures are likely to rise by 0.3 to 4.8 degrees C, or 0.5-8.6 F, by the end of the century depending on how much governments control carbon emissions.

 — Most aspects of climate change will continue for many centuries even if CO2 emissions are stopped.

 — Sea levels are expected to rise a further 10-32 inches (26-82 centimeters) by the end of the century.

 — The Greenland and Antarctic ice sheets have been losing mass over the past two decades. Glaciers have continued to melt almost all over the world. Arctic sea ice has shrunk and spring snow cover has continued to decrease, and it is "very likely" that this will continue.

 — It's "virtually certain" that the upper ocean has warmed from 1971 to 2010. The ocean will continue to warm this century, with heat penetrating from the surface to the deep ocean.

All of this means we need to take action now to avert the various international stability issues that are going to arise as a result of these facts. Whatever money we invest now in reducing emissions will be paltry compared to how much we are going to spend in the next century on dealing with the fallout.

Naturally, the Church of the Climate Deniers are raging in full mouth foam (complete with tin foil hat) about how they are going to be controlled by some sort of secret cadre of New World Order folks. Sadly, they fail to note the number of new markets this could create, the innovation that will occur (most of which will likely come from our country), and ultimately the amount of money to be made from this technology. That latter is what is finally going to get them to come around.
