Global dimming

Post Reply New Topic

Global dimming was first discovered in the 80;s, when it was revealed that the intensity of the sun rays had faded with 22% in Israel and Germany. Moreover, it was soon revealed that this trend was global. The reasons behind the dimming is that the particles which were unleashed by most production and industrial engines until we got catalysators, were mirroring and blocking the sun rays from reaching the Earth.

This process ought to have made the world cooler, but may actually have helped to reduce the effects of the carbon dioxides on our atmosphere. Given this information, we could conclude that global warming is probably much more fervent than we initially thought. If this information is correct, and not some deliberate ploy by industry in order to excuse pollution, it presents a real threat against our civilisation and our continued existence on this planet. The truth is that it is this current civilisation which is the cause for the situation that has brought us here.

We cannot solve the problems by the methods and tools that originally established the problems. You cannot heal a wound with sulphur, and you cannot expect to employ the price system in making the world a more ecologically sustainable place.

1) at all major coal burners pipe carbon dioxide into algae growing ponds.
a) produce biodiesel from the algae oils
b) all new cars plug in , biodiesel electric hybirds.
c) use algea protein to depress world ag prices forcing third world people to stop
clear cutting land for food production.

2) Use pebble bed nuclear reaction technology .

3) solar powered de-humidifer to replace electric AC units.

Let's pretend that the Earth's climate does not change on it's own. Hell, let's blame humans for the ice-ages too.

I've noticed that the Summers have been getting darker, every year.

The problem right now is supposedly that we cannot stop particle pollution into the air due to the effects it will have on global dimming [i.e reducing that and exposing us for more global warming]. Global warming is - if the theories about global dimming are correct - much more stronger than earlier believed. Instead, we must reduce the amount of carbon dioxide in the atmosphere at a comparable amount, at least as much as it will be possible to endure during a transitional period of a couple of centuries. The particles in the air acts as a protective mirror even though they are doing damage to the Earth's biosphere. I agree that we must use the technologies and alterations that you propose, but that cannot be managed efficiently without demobilizing the current economic system.

I answer that other fellow now. Climate changes have for several hundred millions of year been relatively stable. It has been a sort of a dynamic equilibrum, where global cooling is created by forests which thrives on carbon dioxide, resulting in a cooler climate with large ice shelfs that are reducing the forests on the northern and southern hemisphere, thus resulting in global warming. Climate changes are a natural, gradual process.

A gradual process which have been altered by human involvement since the beginning of the industrial revolution. It is not an either black or white issue, but a physical fact that our desire to use carbon dioxide stored in coal and oil have disturbed the natural process and disbalanced the dynamic equilibrum.

if the planet goes to hell it goes to hell. i don't think there's much you can do at this point

Heavy stuff.
I saw the thread title and thought that it was a discussion about how intelligent, well educated people are not having as many children and ignorant or uneducated, inbred people are reproducing at alarming rates. Population is out of control as well as CO2 production. We need to replace billions of people with billions of trees, soon.

Global dimming+Global warming= mmmmm...just right

The climate will change regardless of if we do anything or not, it's a good way of scaring people, if people are scared they are easier to control and will accept more limitations, like more taxes, more surveillence etc

The media and government will constantly use methods to scare people, usually dubious and of little real threat to people.

Recent examples include terrorists and terrorism, climate change and bird flu.

Sure all of them are potential threats, but they are overhyped beyond belief.

Why do this?

For the media they gain profit, bad news sells, and people swallow this scaremongering up easily. The government wants control and surveillence of everything and to tax people more. Do you think either actually care about climate change? Of course not, they haven't done anything worth while towards changing anything, except for stuff that will make them more money. Climate change is not the threat in todays world, the real threat is stupidity.

According to an article I read a few days ago, "global dimming" , caused mainly by polluting industry of the 50s-80s, actually cancelled out global warming as the smog reflected heat.

The amount of CO2 in the atmosphere can be reduced greatly by planting more trees, possibly with growth hormones and/or genetic modification. It would not reverse global warming, but at least slow it. Failing that, perhaps technology could somehow replicate photosynthesis.

Yeah, but it's like a car going full speed with the brakes on: it isn't right, and even if they cancelled each other out perfectly global dimming still causes stuff like severe draughts.
And anyway we're solving the pollution problem but not the global warming, so pretty soon the temperature will zoom up anyway.

Are you sure about that?

There is a body of research that shows the possibility that global warming will hasten the next ice age. The overall temp will be a little higher, but the equatorial latitudes will be uninhabitable, while the only life that will survive will be the species capable of living on or near the massive ice caps. Sounds bass ackwards, but who knows?

Either way, the earth is stable and will survive ... mankind is fleeting and short lived and incapable of affecting long term changes in Earth's system. We are very arrogant, though.

If the population was reduced to ten percent of the present figure, it would help a lot.

Hey!! I've got a plan to make that happen!!

I'd like to see your plan and pitch in.
