BACKGROUND
Global warming, will you adapt to it or stop it?
|  |
In recent years, "global warming" emerges around too much. It seems that include environmental issues in newspapers or books, global warming is considered the most important. And, therefore, efforts to reduce greenhouse gas emissions like energy conservation, renewable energy development and eco-products can be seen frequently. In particular, there is a lot of effort to reduce carbon dioxide that accounts for 80 percent of greenhouse gas emissions. However, are these efforts really effective to prevent global warming?
If greenhouse gas emissions stopped now, even climate change are bound to be sustained over the next few years. Because inertia of greenhouse gases in the climate system will act because greenhouse gases in the atmosphere does not disappear easily. You can also try to reduce carbon consumption, even to zero, you can not create.
There are opinions that now climate mechanism is irreversible because it is already broken, rather it is better to adapt to the hot Earth. Of course, this 'adaptation' means that reduce the warming rate as much as possible through the development of green technology. However, this slow down global warming, will mean that slowly progress to continue.
Even, November 23, 2011, environmental groups 'Greenpeace' presented the shocking report that "Companies that emit the carbon dioxide lobby for block the legislation to prevent global warming". Because of their economic interest they denied to reduce carbon dioxide, even it is insufficient to prevent global warming even if the countries over the world work together and practice the reduction of carbon dioxide immediately.
If so, does we cannot help doing nothing and just wait results? In recent years, one scientist has recognized the limitations, and released another alternative and it has emerged as hot issue. That is geoengineering. There are ways that cheaper than the cost of carbon reduction and be able to run immediately. Scientists who support them argue that we need to study geoengineering for prepare state of irreversible.
We will investigate what technologies are there in geoengineering that perhaps the most aggressive alternative, and what's the limitation and side effects even it is gonna be a more dangerous treatments than disease.
DEFINITION
Geo-engineering ; The Super Idea for Remodeling of Earth. |  |
Today, the greatest threats to mankind are the changes from global warming. So many experts have worked out lots of ways to slow down the velocity of globe getting warm. And there is the one plan which has gained attention recently is the Geo-engineering.
Geo-engineering is the idea of applying planetary engineering to Earth. It would involve the deliberate modification of Earth's environment on a large scale "to suit human needs and promote habitability". The term Geo-engineering is distinct from environmental damage and accidental anthropogenic climate change, which are side-effects of human activity, rather than an intended consequence. Typically, the term is used to describe proposals to counter the effects of human-induced climate change. And in this site, we introduce you the Geo-engineering limiting the range which has relation with global warming.
Geo-Engineering is the one of the hottest idea in recent times for control temperature of globe. This theory includes methods of reducing CO2 gases and blocking the sunlight that cause the global warming, so cooling the earth is the goal of Geo-Engineering. Among these various method, there is one bold example that spraying sulfur aerosols to stratosphere for revealing the effect like as Ash effect.
It is true that seems so incredible and unrealistic. And it also, more over, would accelerate the global warming and environment pollution. But some scientists who stand by Geo-engineering insist that Geo-engineering research must be continued and we prepared for future when we no longer can afford global warming by several method already prepared in present. Because it is also true there are no obvious ways to prevent the global warming though we already have tried much efforts through some policy, like Emission trading and Kyoto protocol, etc., and methods which composed physical treatment.
So, What are the examples of Geo-engineering and How can it cooling the earth? Why some scientists still worry about carrying out Geo-Engineering ?
