I was preparing for my Water Resource midterm exam and i stumble across this, Global Dimming. With lots of curiousity,i went on to research about it to know what is that. It is related to the Global Warming. Global Warming heats up, Global Dimming cools down. In short,it's cooling effect that slows down the Global Warming Effect. With the reduction of visible pollutant particles back in the 80s with cleaner fuels, the Global Dimming effect is reducing,at the same time, the existing carbon dioxide in the atmosphere is speeding up the global warming effect,since there are less cooling. Therefore,more warming. We can see that the climate is getting warmer and the rain is getting heavier. Climate change isnt a hoax.

Just enjoy the documentary. It's a good one by BBC. You'll get a much better idea of it after watching the documentary.











My comments:

I think something has to be done on a global scale as this is much worse than what i have researched on global warming. Fuel and coal burning has to reduced or removed completely as they are the main culprit of this problem. What i have seen so far, there is little being done to stop global warming.

It's quite disturbing to know that the global warming could be happening even faster than what we know. The impact of this isnt any less disturbing than the fact.

Lets discuss about this.

anyway to depend on global dimming to reduce global warming is like drinking poison to cure a fever. in the end you are on the losing side.

Rains are getting heavier this year. As per weather forecast in had been scattered thunderstorm every day for the past 10 days. I don’t think people are serious about reducing global warming. It is only a topic that they like to talk about. At an individual level, people should start cycling if they want to contribute. It is good exercise too. I find the main drawback is the danger of doing it in Kuala Lumpur rush hour traffic. Imagine people use to cycle in China before she open up. Now they prefer to drive. Perhaps it is to reflect their status or merely just convenience.

Atmospheric CO2 concentrations a thousand years ago were higher than it is now. It was also higher during the time of the dinosaurs. Increased carbon in the environment caused numerous adaptations in living things.. plants grew faster and bigger.. marine crustaceans grew thicker shells, etc.

In short, nature always compensates. There are always millions of feedback mechanisms that we do not know about. Up till today, climate modeling scientists are constantly tweaking their feedback mechanisms. We can't even model clouds and precipitation properly yet, and climate models of carbon sinking by limestone and soil is still pretty poor.

On an almost weekly basis, there'll be news about discoveries of new feedback mechanisms, or corrections to the common wisdom of known climate models' feedback mechanisms.

Personally, I think Anthropogenic Global Warming (aka Al Gore Warming) is terribly overblown and the standard IPCC models have "bad science" written all over them. There has been a lot of fear-mongering, ranging from the melting of the Antarctic or the Arctic ice shelves, to runaway greenhouse effect catastrophes.

Global warming alarmists are beginning to sound like the Jehovah's Witnesses. They keep shifting their doomsday prophecies further back. When a model's prediction failed, they'll cook up another excuse and another story. Well and fine, because that's what science is about, always discarding the wrong theories and coming up with more accurate and refined theories. But the problem is, with so many information gaps, how can we say 100% for certain that increased carbon output will lead to further warming, and further warming will cause catastrophes?

The global warming alarmists didn't even see last winter coming. It was the coldest winter in more than a decade. And they didn't even see the extra El Nino forcing coming up early this year. Neither did they even had any clue that the Earth's orbit eccentricity and tilt with respect to the Sun creates 10,000-year variations in global climate, which was only discovered last week.

Interesting topic.

You mean the ice in the arctic didn't melt after all?
