The world's biggest polluters

Some of the answers may surprise you. China has overtaken the United States as far as most total emissions go, as the Asian country has seen its emissions double in the last 10 years.

The biggest surprise, however, may be that Australia has passed the United States as far as highest emissions per capita. It is very surprising to see them higher on the list than countries such as the United States and Canada, which are colder and use much more fossil fuels for heating homes and businesses.

Both the United States and China pledged to address global warming and work on reducing their emissions at a recent U.N. meeting in New York. Both of these countries, as well as many other countries from around the world, will be meeting in Copenhagen next month for the U.N.'s Climate Change Conference. Representatives from countries around the world will work on negotiating a successor to the Kyoto Protocol, which is set to expire.

Senate leaders put climate bill on hold

Democratic leaders in the Senate decided today to put off more debate on the proposed climate change legislation for at least five weeks so the EPA can do an analysis of what the bill would cost to implement.

The delay will mean that any vote on the bill will almost certainly not occur until next year. This also means that no bill will be passed before the U.N. climate change summit in Copenhagen on December 7 despite pleas from German Chancellor Angela Merkel and U.N. Secretary General Ban Ki-moon for the U.S. to set the tone for the discussion by passing its own binding legislation.

With a lack of legislation before the summit, the U.S. team of negotiators will not have any mandate from Congress on what they should negotiate for. This could limit the team's willingness to agree to binding carbon emission reduction targets, something that U.S. negotiators have been hesitant to agree to in the past.

UK's weather service releases climate change map

The Met Office, the UK's national weather service, released an interactive map today that details the catastrophic impact of a four-degree rise (in Centigrade) in global temperatures.

The map is based on a report that the office released last month, where researchers concluded that the world could see a four-degree rise (equivalent to seven degrees Fahrenheit) in temperature over pre-industrial averages by 2060. Temperatures would likely rise more closer to the poles and less in areas around the equator.

The map details scientists' conclusions on the impact of rising temperatures on water supply, forest fires, agriculture, and sea levels. Scientists have also concluded that increased health risks associated with malaria and other airborne diseases would likely occur.

"Climate change is a truly global problem that needs a global solution and it is a solution we have within our grasp," UK's Foreign Minister David Miliband said. "But to tackle the problem of climate change, all of us – foreign ministries, environment ministries, treasuries, departments of defense and all parts of government and societies – must work together to keep global temperatures to two degrees. It is only by doing this that we can minimize the huge security risks presented by a future four-degree world."

Green projects in danger as international climate talks continue

So far, international negotiations for a successor to the Kyoto Protocol have been stagnant at best, even after leaders from 177 countries met in Bangkok last week to discuss a new climate change agreement.

The problem is that the interests of developed countries (such as the United States and most of Europe) and less developed nations (such as China, India, and Brazil) are conflicting. The developed nations want the less developed nations to commit to cutting a percentage of their emissions, but those countries say that the developed nations are the ones responsible for climate change and also have the money to make the cuts, so they should have to do most of the work. In a way, both groups have a good point and are right in a lot of respects.

However, debate over how the new agreement should be structured and what it should contain aside, if leaders fails to agree on a new climate change treaty, many green projects around the world are in danger of being shut down after 2012. Obviously, this would be a travesty, as much of the progress those projects have made would be lost.

Global warming debate heats up

With the landmark Copenhagen climate conference just a little more than two months away, news surrounding a potential successor to the Kyoto Protocol is heating up. Last week, representatives of the so-called G20—finance ministers and central bank governors of 20 major national economies—met in Pittsburgh to discuss global warming, among other things.

As the pivotal conference approaches, scientific reports are coming out that are raising the stakes. The U.N. released a report this week that states that the world is on course for a 6.3 degree temperature increases even if all the proposed actions are implemented by every government worldwide. Part of the report is particularly scary as it states that the worst-case scenarios for global climate disasters are actually worse—and not as far in the future—as previously thought.

For a good summary of all the recent news in the global warming debate, check out this story from The Daily Green that contains links to six items that are making news.

U.S. and China make climate change pact

U.S. State Department and Chinese officials signed a pact today to work together to cut down on greenhouse gas emissions by promoting environmentally-friendly technologies.

The U.S. and China are the two leading emitters of greenhouse gases in the world. While the deal is almost entirely symbolic because it contains few specific details, the fact that the two countries can agree on this is a good thing as the U.N.-led climate change negotiations approach later this year. At the negotiations, countries from around the world will meet in Copenhagen in an effort to form a treaty to succeed the Kyoto Protocol.

Secretary of State Hillary Clinton had this to say of the pact: "[The agreement] provides our countries with direction as we work together to support international climate negotiations and accelerate the transition to a low-carbon economy."
