Climate change already harming the global economy


Never mind what's going to happen in 2100: climate change is already shrinking the global economy.
According to the Climate Vulnerability Monitor – a report by Spanish non-profit organisation DARA – in 2010 climate change shaved 1.6 per cent off global gross domestic product. The figure was calculated by adding the harmful effects of climate change to the problems of the carbon-based economy, such as air pollution.
Previous studies, such as the 2006 Stern Review, concluded that climate change would not become a net cost for decades. But they had not considered climate's impact on productivity. As the temperature increases,people work less well. "It has been assumed that a hotter living and working environment is nothing to worry about," says Tord Kjellström of Umeå University in Sweden. "But the 5 billion people living in the hot parts of this planet are already constrained by heat."
Climate change now costs more than the emissions cuts that are needed to tackle global warmingMovie Camera. Such cuts would cost 0.5 per cent of global GDP, whereas the cost of climate change will be 3.2 per cent of GDP by 2030. If the claims stand up, it boosts the case for urgent action, says Cameron Hepburnof the London School of Economics. "Caps on emissions should be much tighter, and carbon prices much higher, than they are now

How You Can Fight Global Warming at Home

There are steps you can take to fight global warming in your home and car. You do not have to wait for the government or big businesses to do something about it. It is better to take the initiative and do your part.
In your home, you can begin by changing your light bulbs. You do not have to do it all at once. Every time you change a bulb, though, you can replace the old incandescent bulb with a compact fluorescent. Not only does this reduce greenhouse gases, it also saves you money in the long run.

It has always been wise to seal and insulate your home, just for comfort's sake. Now, it is even more important. You can stop your home from emitting greenhouse gases and contributing to global warming by doing this. If you have any doubts about where your home needs insulation, you can hire an energy auditor to help you decide.

You can reduce global warming by simply taking care of the cooling and heating equipment in your home. You can change filters and have the equipment cleaned. Most importantly of all, when the heater or air-conditioner needs to be replaced, get an efficient model that is big enough for your dwelling.

In fact, it makes sense to buy all your appliances with energy efficiency in mind. Energy Star is a rating system that is reserved for efficient products. Buying such products will help decrease global warming.

Recycling is one of the easiest ways to help reduce global warming. Everyone can do it with little effort. You can also further the process by using products that are made from recycled materials.

You can help reduce global warming in your lawn, too. For one thing, you can use a push mower instead of a power mower. Since a push mower uses no energy but your own, this is a great savings. Even if you do use a power mower, you can still help. Use a mower that catches the grass clippings so you can mulch them.

As far as transportation, you can do so much more than buying a green car. You can drive it sensibly, with no rapid starts for instance, to help prevent global warming. If you keep your car well-maintained, it will be beneficial, too. Things like changing your oil and keeping your car tuned up can make a big difference in global warming.

Surprisingly, poorly inflated tires can lead to global warming. This happens because tires must have the proper amount of air in them for the car to reach maximum fuel efficiency. The less efficient your car is, the more it adds to global warming.

The best way to slow global warming by the way you use your car, is to make as few trips as possible. Walk when you can. When you have to drive, combine as many errands into one trip as possible.

If you fight global warming in your home and your car, you can make a difference. Some basic changes can be easily made. If everyone makes these simple changes, it can have a powerful impact on global warming.

The Basics of Global Warming

Scientists, celebrities, and everyday people have been trying to understand the nature of global warming. Controversy is rampant and there is intense debate around the world on the subject. Since conclusions drawn could affect you profoundly, you may want to know some basic facts about the topic of global warming.



The most obvious thing that can be said about global warming is that the earth is getting warmer. Specifically, the temperatures near the surface of the earth and the temperatures in the ocean are rising. Since 1990, there have been 10 years that have been hotter than any others in recorded history.

The greenhouse effect is said to be responsible for global warming. The greenhouse effect causes certain vapors and gases to form a sort of blanket that covers and warms the earth. Water vapor, methane, carbon dioxide, and several other trace gases make up this blanket.

The greenhouse effect itself is not disputed. No controversy exists on this point because the greenhouse effect is recognized as an inherently beneficial process. If all the energy that struck the earth was reflected right back into space, no one could live on earth. This is what would happen without this blanket that is caused by acceptable levels of global warming.

However, global warming is not all good. It can cause the earth's covering to increase in density. With a denser blanket over the earth, less of the heat is reflected back into space. This upsets the delicate balance between heat and cold that is usually maintained on earth. It traps more heat inside the earth's atmosphere.

Although there are people who argue against it, there seems to be a change in the climate in recent years. Climate change to a warmer climate is the result of excessive global warming.

There has been an overall rise in temperature of a little over one degree Fahrenheit during the last century. The figure for this century is expected to be more like seven degrees. It is this type of global warming that can lead to dire consequences if left unchecked.

People, their activities, and their industries have caused global warming to reach the levels it has today. Burning fossil fuels, powering electrical plants with coal, and irresponsible land use can all contribute to global warming. Carbon dioxide is produced by these activities, and global warming is perpetuated.

Global warming could result in rising sea levels and flooding. There could be more powerful storms. Heat waves could become intense. Droughts could severely damage the world's crops and cause shortages of drinkable water. Extinction of species could become a problem because of changing habitats and the suitability of the climate for the animal.

The good news about global warming is that there are ways to slow the process down. Each person can take responsibility for doing their part in protecting the earth's environment. With everyone helping, emissions of greenhouse gases can be cut drastically. This will give the earth a chance to begin to regain its balance of temperature. Knowing about global warming can make you a better citizen of the world.
