Global Warming Issues Summarized for 2008


I am grateful to a dear acquaintance who requested a brief update on global warming. She wanted a current problem summary.   I rise to the task and offer this one page overview.


The following is a distillation of a year spent reading, studying and ranting. Statements footnoted with links.

Most all scientists will agree that:

1. Global warming is real; is made much worse by human civilization; and is accelerating.

Weather channel has the message

2. We can no longer fix it.  We can only adapt, mitigate and suffer the consequences.

Adaptation: Wikipedia
Public Health perspective

3. We have begun to act.  But over the next few decades - if we do little or nothing - humans will go the way of the dinosaurs.

4. Actions taken now require 30 to 50 years for effects to begin — and thousands of years to completely revert to a healthy atmosphere.

5. Model scenarios do not exclude a prediction of horrible calamity.   We do not know the time-line for anticipated changes.   Farther out in time is much harder to predict.—

6. Climate change is dangerous because of “tipping points” - an important concept to know - where one event triggers another.  Like connected, amplified teeter-totters.   Science has a hard time with tipping points, because they lead to greater complexity and runaway impacts

7. Currently, scientists are disturbed to note the rate of change is picking up.—
Research shows rapid changes in the past
Oceans warmed 50% faster over the last 40 years to climate change

8. For decades the fossil fuel industry has funded huge PR campaigns to discount the science and restrict legislative reactions that would stifle their business.   These have been very effective.   The Executive branch has actively suppressed government studies on global warming.  Seemingly intelligent people will often deny brutal truths.

Scientists are far more concerned than is reflected by public opinion; they have very little voice in this issue, business has much.

Systematic suppression of science - George Monbiot
“…the problem is not that people aren’t hearing about climate change, but that they don’t want to know. The professional classes have the most freedom to lose and the least to gain from an attempt to restrain it.  Those who are most responsible for carbon pollution are - being insulated by their money - the least likely to suffer its effects. “
…we all have our self-justifying myths.  We tell ourselves a story of our lives in which we almost always appear as the heroes. These myths prevent us from engaging with climate change…
…The most powerful story of all, endlessly narrated by the hired hands of the fossil fuel industry, just as it was once told by the sugar slavers, is that we are both all-important and utterly insignificant.  We are too important to be denied any of the delights we crave, but too insignificant to exert any impact on planetary processes.  We fill the whole frame of the story when it suits us and shrink to a dot when that scale is more convenient. We are capable of occupying both niches simultaneously…
…It is not just because (the movie) The Great Global Warming Swindle is at odds with the entire body of scientific knowledge on this subject that I have bothered to contest it. It is also because it is consonant with the entire body of human self-deception. We want to be misled, we crave it; and we will bend our minds into whatever shape they need to take in order not to face our brutal truths.   - George Monbiot 7-22-08

9. Europe and other nations seem to better understand the problem than the US.  Most humans will not really get it until they feel the sea level rise and experience more storms, floods, heat waves, bio changes, crop losses, etc.

10. Dramatic and painful climate problems happening sooner will better work to stimulate change.   Any changes made now are more effective than the same change enacted in the future.   The longer we wait, the harder it gets. (8 years have been wasted)

11. Most adults alive today will see more and increasingly intense global warming problems; Children growing into a very unpredictable world will need all the preparation we can give them.  Philosophically: we should learn the dangers, still enjoy life, educate the kids, and push change as fast as we can.   No engagement is more important.

For background see the movie ‘An Inconvenient Truth’ - remembering that the science in that movie is now about 5 years old.

You missed one. Al Gore has the same problem as does a Butt Rouger in a cold Baboon Mortuary. He just cannot understand why intelligent people do not realize how important his job is!

how did global warming start? when will it end?

Sadie: You are asking some very fundamental and important questions.

When did it start?

Change in climate has always been happening. Always up and down over millions of
years. Global warming is a moving process constantly changing. Think of it as a
wagon rolling along - faster and slower but always in some motion. Humans come
along and push the wagon moving it faster. And by our machines and carbon fuels we
push it faster and faster. Climate changes naturally, it is just that recently humans
have been influencing warming much more and faster than appears to be natural.

Today scientists call global warming "substantially human driven". People are pushing
that wagon, and it is moving faster than if no one was around touching it. If humans
can push, we can pull, we like to think we can slow things down with our effort.

So when it will end ?

It won't; lets change that question slightly ...Global temperatures will always change up
and down according to physical and chemical laws. And humans - who are physical
and chemical beings are influencing that greatly. Like lots of people in a small room or
filling up an elevator cab to maximum capacity - pretty soon it gets warm in there.
And if everyone lit a match or was smoking cigars then it would get warmer much
faster and very soon would not be healthy to be there. That is why we have rules
about no smoking in elevators. And we have started to have rules about not heating
the atmosphere. The international ban on gasses to preserve the ozone is one example
that has worked well.

The earth will not end. The planet will continue OK...But the climate and oceans and
land will develop destabilizing problems so bad that people may have a hard time dealing with it. There could be problems like - stronger storms, rising sea levels, droughts and floods and heat waves - which could trigger other problems like disease, plant extinctions, crop failures, drinkable water, and climate refugees that will be moving
away from all these problems.

And if humans can slow the warming and stop it then we could live in the world longer. We can influence the climate by restraining activity that makes it worse. Stop pushing
the wagon.

As to when it will get better, the answer is that it is a slow process but most governments have decided to make it better and have started. The two words are "adapt and mitigate" But much more work and new ideas are needed. It will take many, many generations and humans will be facing a faster rate of change. Future generations will have a bigger challenge than we have now. Don't you think we should start working now?
