Global Warming “Irreversible” Warns Scientific Body

Global Warming “Irreversible” Warns Scientific Body
  • 1 of 2

Governments, corporations and individuals could cut greenhouse gas emissions today, and it would still be too late to stave off disaster. What is left to us now is mitigation and adaptation. That is the conclusion of the American Meteorological Society (AMS) in an Information Statement published August 20, 2012.

Their conclusions are yet more confirmation that the dire predictions of the 1972 report, “Limits to Growth”, were accurate. The MIT researchers who prepared that publication had entered a variety of population and economic scenarios into a computer model. Most of the scenarios resulted in the same outcome: the collapse of the global economy in 2030.

The researchers did say there was a way to avoid the disaster: drastic measures to the protect the environment. Forty years later politicians are still arguing over whether or not climate change is real and human caused. Corporations are continuing to act as if resources were infinite. Consumers are still being seduced by the latest goods to hit the market.

AMS Ratchets Up the Alarm

In 2007 AMS issued a statement on climate change that concluded:

Despite the uncertainties noted above, there is adequate evidence from observations and interpretations of climate simulations to conclude that the atmosphere, ocean, and land surface are warming; that humans have significantly contributed to this change; and that further climate change will continue to have important impacts on human societies, on economies, on ecosystems, and on wildlife through the 21st century and beyond.

The note of uncertainty is gone in the 2012 statement:

There is unequivocal evidence that Earth’s lower atmosphere, ocean, and land surface are warming; sea level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking. The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research. The observed warming will be irreversible for many years into the future, and even larger temperature increases will occur as greenhouse gases continue to accumulate in the atmosphere. Avoiding this future warming will require a large and rapid reduction in global greenhouse gas emissions. The ongoing warming will increase risks and stresses to human societies, economies, ecosystems, and wildlife through the 21st century and beyond, making it imperative that society respond to a changing climate.

Alexandra R, I use all my butterfly awards for tree planting. : )

We can't convince these people because they only tune into right wing corporate information sources. They are told every day that climate change is a hoax. Look at Texas, even after the record drought and dust storms millions of Texans still believe global warming is false.

The information is not complicated. The data has been verified.
It's mind blowing that so many are unable to grasp what is going on and deny it.
Maybe one needs to become a super communicator to get the facts through to some people in psychotic denial. I've decided to study neuro-linguistic programming and then do my best to get the message across to as many people as I can.
I've been planting trees like mad, but now, with my buttefly rewards, I'm buying cement to build efficient home stoves so that people do not have to cut down so many trees to cook with and for heating their huts.

@ Kathy P.” we can do our best to prevent further damage! “Really ? Like what ? Haven’t you read the posts from Don I., Kevin B , Elaine A and Gary R. informing us that there has been no change and that oil will continue to benefit our lives ? There are far too many like them who are JUST NOT INTERESTED ! Clearly, NO WE CAN”T.

we can't erase what has been done but we can do our best to prevent further damage!

Theresia K.: Thanks for injecting an important fact that is often ignored in the "global warming" issue!

Scott R.: You say "we should be clamoring for funding". Do you mean "funding" by taxpayers? If all you say is true, why shouldn't investors and entrepreneurs be clamoring to get in on the "golden opportunity"? Generally, open markets and entrepreneurship are much faster and more efficient at producing funding for worthwhile projects than is government, which entails cumbersome, controversial, and time consuming processes which are distorted by conflicting special interests and political partisanship. Open markets foster competition that creates powerful incentives to achieve the best results in the shortest amount of time.

There is one very important line of reasoning and that is to move away as fast as possible from a carbon-based energy economy. In other words putting an end to the Age of Carbon in our lifetime. To do so requires a fundamental breakthrough in energy storage science. The only reason we use petroleum and other fossil fuels is that they contain a huge amount of energy relative to weight and volume. Energy density is everything. It is the coin of the realm, so to speak. To put an end to our carbon-based energy economy means we have to come up with an alternate way to store energy. Enter Solid State Energy storage. This is the next evolutionary jump from 200 year old chemical-based 'battery' solutions to solid state systems that can safely store and distribute massive amounts of electricity the same way modern computer networks store and move data globally. These super capacitors are in development and will change everything. This disruptive new technology will make fossil fuels obsolete the same way whale oil was displaced by petroleum. We should be clamouring for funding to advance this area of material science as fast as possible. It will change everything.

Huber F, could you clarify your post? I do not understand what you mean.

2:09PM PDT on Sep 12, 2012

I would hope it is since we have gone pretty far now

Global warming is endurance politics into which regions are actually supporting their environs. This is backward thinking in destroying new theories of survival.
