Halt all carbon emissions by 2050: Worldwatch

To avoid the most catastrophic effects of climate change, world carbon emissions will have to drop to near zero by 2050 and "go negative" after that, the Worldwatch Institute reported on Tuesday.

This is a deeper cut than called for by most climate experts and policymakers, including President-elect Barack Obama, who favors an 80 percent drop in U.S. carbon emissions by mid-century.

Limiting carbon emissions aims to keep global mean temperature from rising more than 3.6 degrees F (2 degrees C) over what it was before the Industrial Revolution -- but one Worldwatch author said even this is too dangerous.

"Global warming needs to be reduced from peak levels to 1 degree (Celsius, or 1.8 degrees Fahrenheit) as fast as possible," co-author William Hare said at a briefing on the "State of the World 2009" report. "At this level you can see some of the risks fade into the background."

Global mean temperature has already risen 1.4 degrees F (0.8 C) since 1850, so drastic cuts in emissions of climate-warming carbon dioxide are needed, according to Hare, now working at the Potsdam Institute for Climate Impact Research in Germany.

Hare said that global greenhouse gas emissions would need to hit their peak by 2020 and drop 85 percent below 1990 levels by 2050, and keep dropping after that. He said carbon dioxide emissions would have to "go negative," with more being absorbed than emitted, in the second half of this century.

The burden of cutting greenhouse emissions should fall more heavily on rich countries than poor ones, Hare said, with industrialized nations reducing emissions by 90 percent by 2050, allowing developing nations to let their economies grow and develop new technologies that will ultimately reduce climate-warming gases.

2009: A PIVOTAL YEAR?

Even with these dramatic changes, the world may face an additional rise of nearly 1.8 degrees F (1 degree C) because the impact of past greenhouse emissions hasn't yet been felt on surface temperatures, the report said.

This year could be pivotal in the movement against climate change, said co-author Robert Engelman, with "scientists more certain and concerned, the public more engaged than ever before, an incoming U.S. president bringing to the White House for the first time a solid commitment to cap and then shrink this country's massive injections of greenhouse gases ... into the atmosphere."

Engelman also noted this year's deadline for a global agreement to craft a successor pact to the carbon-capping Kyoto Protocol. This is set to happen in December at a meeting in Copenhagen.

Engelman said the Copenhagen meeting could put in place a new "financial architecture" that discourages greenhouse emissions and rewards actions that take these emissions out of the atmosphere.

This could take the form of a cap-and-trade system or a carbon tax, he said, and could also include "the best terms of trade, investment and credit" for countries that make the transition to a low-carbon economy.

"However this turns out, we still have some precious time and a clear shot at safely managing human-induced climate change," Engelman said. "What's at stake is not just nature as we've always known it, but quite possibly the survival of our civilization. It's going to be a really interesting year."

Commenting on the report, environmental chemist Stephen Lincoln of the University of Adelaide in Australia said in a statement: "The strongest message from State of the World 2009 is this: if the world does not take action early and in adequate measure, the impacts of climate change could prove extremely harmful and overwhelm our capacity to adapt." 

The Washington-based Worldwatch Institute is an independent research organization.

Years after digital television became normal in Australia, another digital experience is upon us - digital radio. It aims to take the way we listen to the radio to a whole new level. But will it actually take off?

We are now in an age where we have mp3 players allowing us to choose songs at the press of a button. Apple recently posted a quarterly profit of 47% boasting that even in the weak economy, consumers are still buying.

Digital radios have the ability to pause and rewind to their advantage, as well as extra channels. However, I am hesitant as to whether this new listening experience will appeal to listeners. When driving in the car, I feel the listening experience is maximised when listening to an iPod allowing the consumer to choose exactly when they want to listen to their song or podcast.

Hundreds of podcasts are flooding the internet and a lack of radio programs available by podcast is hardly a concern. On the flip side, dedicated news and sports channels can be provided and thus appeal to niche markets. This development would have been well used and suited to consumers lifestyles a decade ago, when iPods were starting to enter the market.

This new development in radio is ahead of countries like Germany, Italy and China. I guess we’ll have to wait to see if Australians adapt to this new form of radio and digital media.

Re: The Pointless Question of "What is Art?"

You're article serves as a blatant example of people's lack of knowledge/interest in the contemporary art scene. Some of the most profound and revealing conversations stem from dicussions of art, politics and religion so why label them taboo subject matter? why not let the idiots add in their artistic two cents, because who knows what could happen? a change of opinion... an education... a flash of interest? Perhaps you and your friends to venture down to the COFA 09 annual exhibit and see some 200 fresh sydney artists emerge onto the art scene, unless it's too boring/inane. - Kara

Re: The Pointless Question of "What is Art?"

I dare say the question is not pointless but rather is made pointless by overcomplications of academia and peripherals of market and status, in which Sean appears to have gotten bogged down notwithstanding the word limit. One of the things we do know about art for a fact is that we humans appear to have always had it around from the caves (who can forget the fetching bison from Alta Mira!) So the issue is cutting through the baggage of history as old as humanity to get back to the fundamentals. It took me about 35 years of research but does not take 100 words. It is this: "Art is something that is designed to communicate thoughts and feelings and to influence our thoughts and feeling through one or more of our senses."(25 words) Since we have space, a rider: "The particular art form is qualified by the particular senses involved in production and reception of that communication. If Sound then Music, If body then Dance. If we use eyes to perceive colour and shape we call it Visual art." How you work the item in question is the matter of objectivity after all some of us eat fruit raw and others make jam. If you choose to make art an investment go for it, if you choose to make it a status symbol you won't be the first. However, in my book, art is really the best at being art and in the immortal words of one Oscar Wilde, for any other purpose "All art is quite useless" - Valerie (Co-incidental author of "Why Art? The Pocket Art Expert)

Re: ETS Voted Down: Rudd Proves Himself An Evil Genius

Nice to see such an insightful article, despite the snide comments.. Did you read the Quarterly Essay by Guy Pearse in writing the first 5 paragraphs- not that that's a bad thing really. Nice of you to widen your vision beyond the road ahead and take in some history- but I would add one thing- that as it stands (in the senate, especially with Steve Fielding) we won't have a real, meaningful ETS passed. The bummer is that even with a double dissolution election and the resultant simultaneous sitting of both houses of parliament (which as you point out, the greens/minor parties and labor would benefit from) would still not change the ETS from it's current configuration- not unless the Greens tripled their vote. Silly that it all came down to labor preferences to a little known party led by a little know bloke named Steve Fielding and Family First- not that that should be the reason we're in this predicament... - Shaun Lambert

Re: Evil Capitalists

In response to the "100 Words" on Psychotic Capitalism: The statement, "only psychotics fail to distinguish right from wrong," has a semantic problem. What makes a person psychotic is the inability to recognize that, theoretically, actions or behavior can be right and wrong. A psychologically normal person can do this by age 5. But well- intentioned people constantly disagree about which actions are right and wrong in particular situations. This evening my husband and I re- watched "Zeitgeist--- Addendum" on youtube. We had to restrain ourselves from a festival of paranoia, anger and frustration at what appears to be an evil plot to enslave us all, to bleed us like pods in The Matrix. I cannot argue against the idea that Capitalism--- looked at as a planetary movement--- seems heartlessly destructive, yet there is no single person or even group of Illuminati to blame --- we are willing participants in this plot to rule the world, exploit the human race, rape Mother Earth. All of us are not psychotic, rather we are doing what seems right, and we are following norms set by our culture and community. I personally do my best to support those lawmakers who help us define right at wrong at the transpersonal level--- where this kind of crime being committed, with vast and ultimately very personal consequences. Indeed people can be stupider and meaner in groups than singly --- but whatever the right word is for that, it is not psychotic. Our real problem is that we seem incapable of seeing consequences beyond the local and immediate, we are selfish and shortsighted. But the writer is right: stupid, mean, selfish, shortsighted --- these terms trivialize the unfathomable crimes of Capitalists and their sheep-like dupes. - Anna Willis

Re: Australia's Swine Flu vaccination plan

The word "pandemic" has absolutely nothing to do with a deadly disease taking over the planet. The definition of "Pandemic" is simply about the SPREAD of a disease. Any disease. It could be a relatively harmless disease like the Swine Flu, to maybe a more harmful type (like normal seasonal influenza). Nothing to do with how bad or how good it is to your health ... just how WIDESPREAD it is. That is the interpretation of "Pandemic". A word that is nothing to be scared about, but just a measure of the SPREAD of any disease (harmful or relatively harmless) around the globe. The original "Spanish Flu" in 1819 killed 50 to 100 million people worldwide. Swine Flu deaths to date? 2,800 or so. Compare this to up to 500,000 deaths worldwide from our ongoing "Seasonal Flu". People need to see things in perspective. Swine Flu is a mild flu. No need for risky & possibly dangerous vaccinations. No need to be scared. In fact NO NEED TO DO ANYTHING. Just stay cool and take whatever vitamins & health supplements that are appropriate. Good luck & stay informed. - Tim

Re: Why we shouldn't care about he loneliness of the University Liberal

While you have managed to approach, with a complete lack of understanding and sensitivity, the complaints of the many people who feel alienated by the overtly leftist university agenda, I also think that you have failed to address the concerns of an increasingly disenfranchised leftist populace. The article was concerning the Left Handed bigots, not the personal politics of either of the 4 people mentioned. Their concern was not with, as you pointlessly attacked, their political beliefs, but rather with their freedom to express their beliefs and how they were treated on campus because of them. I write this as a disenfranchised leftist. Apparently, freedom of speech on campus somehow took a backseat to the far left's bigotry, however well intentioned they thought it was originally. I'm not right; I'm not left. But fuck anybody that tries to censure me and revoke my right to freedom of speech, merely for believing in a political party. Anyone that thinks that's OK, well simply look up the definition of fascist. - I Swing My Vote

Re: Why we shouldn't care about he loneliness of the University Liberal

Sean Maguire makes some useful points in rebutting Paul Sheehan's puff piece about nasty lefties on campus. But he does Socialist Alternative a disservice by suggesting the Liberals stereotype us in the same we stereotype them. We don't stereotype Liberals; we understand the role they play (like Labor) in continuing the exploitative system that is capitalism. The suggestion in Sheehan's article that we would direct anti-semitic language at Liberals is a lie. We are opposed to Zionism, the apartheid philosophy which justifies on-going genocide against Palestinians. We are opposed to racism. We think that the political liberation of both Jews and Palestinians lies in a one state solution - a rainbow nation for all who want to live in a democratic and secular Palestine. To tar those who oppose Zionism with the brush of anti-semitism is cheap trick designed to avoid debate about the reality of Zionism and in this case to smear with a gross lie the Liberals' political opponents on campus like Socialist Alternative. Some leftists may have mistakenly called Liberals fascists. If so this is to misunderstand the class enemy. Liberals are not fascists; they are anti-working class warmongers. It is important to keep that distinction and truth in mind. - John Passant

'Living in denial' The Australian Fim Industry was absolutley the best bit of journalism Ive read in a long time. Robert was spot on in every point of his discussion. IT laso should be noted it also affects our talent pool as well, as they end up heading overseas to find work and make a living in better evolved film enviroments. Hopefully one day the Film Industry, governments (and acting/film schoolsas well) will realise this epidemic and inject some much needed life and diversity in the industry to make us, 'the audience' want to go to an australlian movie.
