Climate Change: Why We Can't Wait

Image
James Hanson, The Nation This is an adaptation of a talk delivered February 26 at the National Press Club. Comments relating to policy are Dr. Hansen's personal opinion and do not represent a NASA position. There's a huge gap between what is understood about global warming by the relevant scientific community and what is known about global warming by those who need to know: the public and policy-makers. We've had, in the past thirty years, one degree Fahrenheit of global warming. But there's another one degree Fahrenheit in the pipeline due to gases that are already in the atmosphere. And there's another one degree Fahrenheit in the pipeline because of the energy infrastructure now in place -- for example, power plants and vehicles that we're not going to take off the road even if we decide that we're going to address this problem. The Energy Department says that we're going to continue to put more and more CO2 in the atmosphere each year -- not just a...

Arctic Sea Ice is Shrinking in ‘Downward Spiral’

Image
Winter sea ice in the Arctic has failed to reform fully for the third year in a row. Scientists said yesterday that the area of ocean covered by Arctic ice at the end of the winter months was lower only in March 2006. Researchers fear that the floating sea ice is now on a downward spiral of shrinkage that cannot recover fully even during winter because of warmer temperatures. Walt Meier of the US National Snow and Ice Data Centre in Boulder, Colorado, which released the satellite data yesterday, said: “We’re seeing near-record lows and higher-than-normal temperatures. We expect the downward trend to continue in future years.” More...

Top Scientists Warn of Water Shortages and Disease Linked to Global Warming

Top Scientists Warn of Water Shortages and Disease Linked to Global Warming By THE ASSOCIATED PRESS WASHINGTON, March 11 (AP) — The harmful effects of global warming on daily life are already showing up, and within a couple of decades hundreds of millions of people will not have enough water, top scientists are likely to say next month at a meeting in Belgium. At the same time, tens of millions of others will be flooded out of their homes each year as the earth reels from rising temperatures and sea levels, according to portions of a draft of an international scientific report by the authoritative Intergovernmental Panel on Climate Change. Tropical diseases like malaria will spread, the draft says. By 2050, polar bears will mostly be found in zoos, their habitats gone. Pests like fire ants will thrive. More...

The Big Green Fuel Lie

Image
by Daniel Howden in Sao Paolo, lndependent/UK The ethanol boom is coming. The twin threats of climate change and energy security are creating an unprecedented thirst for alternative energy with ethanol leading the way. An ethanol plant is seen by sugar cane fields in Piracicaba, Brazil, Friday, March 2, 2007. Just an hour's drive outside this traffic-choked metropolis where U.S. President George W. Bush kicks off a Latin American tour Thursday, sugar cane fields stretch for hundreds of kilometers, providing the ethanol that fuels eight out of every 10 new Brazilian cars. That process is set to reach a landmark on Thursday when the US President, George Bush, arrives in Brazil to kick-start the creation of an international market for ethanol that could one day rival oil as a global commodity. The expected creation of an "OPEC for ethanol" replicating the cartel of major oil producers has spurred frenzied investment in biofuels across the Americas. But a growing number of ...

UK Plans to Cut CO2 Doomed to Fail - Scientists

Image
by James Randerson, UK Guardian An independent scientific audit of the UK's climate change policies predicts that the government will fall well below its target of a 30% reduction in carbon dioxide emissions by 2020 - which means that the country will not reach its 2020 milestone until 2050. The report condemns government forecasts on greenhouse gas emissions as "very optimistic" and projects that the true reduction will be between 12 and 17%, making little difference to current CO2 emission levels. The report is based on an analysis of the government's attempts to meet climate change targets. The authors argue that because much policy is based on voluntary measures, the predicted outcomes cannot be relied upon. It is released on the day the environment minister, David Miliband, delivers a speech on the UK's transition to a "post-oil economy". More...

China About to Pass US as World's Top Generator of Greenhouse Gases

Image
by Robert Collier, San Franciso Chronicle Far more than previously acknowledged, the battle against global warming will be won or lost in China, even more so than in the West, new data show. A report released last week by Beijing authorities indicated that as its economy continues to expand at a red-hot pace, China is highly likely to overtake the United States this year or in 2008 as the world's largest emitter of greenhouse gases. This information, along with data from the International Energy Agency, the Paris-based alliance of oil importing nations, also revealed that China's greenhouse gas emissions have recently been growing by a total amount much greater than that of all industrialized nations put together.

Study Questions Prospects for Much Lower Emissions

Image
WASHINGTON, Feb. 14 — As Democratic leaders in Congress prepare to put climate change legislation on the agenda, some in the utility industry are arguing that it will take decades of investments and innovation to get substantial reductions in their emissions of greenhouse gases. A Path to Reduced Emissions Electric power companies, which emit about one-third of America’s global warming gases, could reduce their emissions to below the levels of 1990, but that would take about 20 years, no matter how much the utilities spend, according to a new industry study.

Boycott America?

Image
The fact that humans have contributed to the current problem of global warming is “unequivocal” according to the recent report from the Intergovernmental Panel on Climate Change. Webster’s definition of “unequivocal” tells us: not equivocal; unambiguous; clear; having only one possible meaning or interpretation; absolute; unqualified; not subject to conditions or exceptions. This is the most definitive information we have on the issue of global warming and ends the speculation about causal effects of our activities. Doubters will now have to get down to the business of securing our future. There is no more “us and them” in regards to our next evolutionary step and all indications are that we must act quickly and decisively. The damage we have created up until now will be felt for the next 1.000 years and so too will be the significance or our future actions or inactions. History has called on us with challenges in the past and we have risen to the occasion. Reducing our carbon output ...

Millions to Go Hungry, Waterless: Climate Report

Image
by Rob Taylor, Reuters, Posted on Commondreams Rising temperatures will leave millions more people hungry by 2080 and cause critical water shortages in China and Australia, as well as parts of Europe and the United States, according to a new global climate report. By the end of the century, climate change will bring water scarcity to between 1.1 and 3.2 billion people as temperatures rise by 2 to 3 Celsius (3.6 to 4.8 Fahrenheit), a leaked draft of an Intergovernmental Panel on Climate Change (IPCC) report said. The report, due for release in April but detailed in The Age newspaper, said an additional 200 million to 600 million people across the world would face food shortages in another 70 years, while coastal flooding would hit another 7 million homes. "The message is that every region of the earth will have exposure," Dr Graeme Pearman, who helped draft the report, told Reuters on Tuesday. "If you look at China, like Australia they will lose significant rainfall in ...

Electric cars the answer for the future -- and the present

Image
By Candace Page Free Press Staff Writer MONTPELIER -- Electric cars will "inevitably" replace gasoline-powered vehicles in coming decades, a Vermont researcher told lawmakers Wednesday, and the state can take steps now to prepare for and help speed the transition to a cleaner transportation system. "The plug-in hybrid is the car of the future," Prof. Steven Letendre of Green Mountain College testified, "but this isn't futuristic stuff. These cars are out there now. Companies are taking the (Toyota) Prius hybrid and altering them to plug into the electric grid. They'll get 100 miles to the gallon." Letendre was one of three speakers on the fourth day of a legislative inquiry into climate change and the ways Vermont can reduce its contribution to the greenhouse gases blamed for global warming.

A Coalition for Firm Limit on Emissions

Image
By FELICITY BARRINGER , NY Times WASHINGTON, Jan. 18 — Ten major companies with operations across the economy — utilities, manufacturing, petroleum, chemicals and financial services — have banded together with leading environmental groups to call for a firm nationwide limit on carbon dioxide emissions that would lead to reductions of 10 to 30 percent over the next 15 years. Introduction of this group, which includes industry giants like General Electric , DuPont and Alcoa , is aimed at adding to the recent impetus for Congressional action on emissions controls and the creation of a market in which allowances to emit carbon dioxide could be traded in a way that achieves the greatest reduction at the lowest cost.

Behold the Rise of Energy-Based Fascism

Image
The Pentagon is helping to create a grim future for all of us: a struggle for energy primacy abroad and Big Brother at home. By Michael T. Klare , Tomdispatch.com ., post on Alternet. It has once again become fashionable for the dwindling supporters of President Bush's futile war in Iraq to stress the danger of "Islamo-fascism" and the supposed drive by followers of Osama bin Laden to establish a monolithic, Taliban-like regime -- a "Caliphate" -- stretching from Gibraltar to Indonesia. The President himself has employed this term on occasion over the years, using it to describe efforts by Muslim extremists to create "a totalitarian empire that denies all political and religious freedom." While there may indeed be hundreds, even thousands, of disturbed and suicidal individuals who share this delusional vision, the world actually faces a far more substantial and universal threat, which might be dubbed: Energo-fascism, or the militarization of the gl...

Vegetarian is the New Prius

Image
by Kathy Freston, Huffington Post, posted on Commondreams Last month, the United Nations published a report on livestock and the environment with a stunning conclusion: "The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global." It turns out that raising animals for food is a primary cause of land degradation, air pollution, water shortage, water pollution, loss of biodiversity, and not least of all, global warming. "According to the UN report, it gets even worse when we include the vast quantities of land needed to give us our steak and pork chops. Animal agriculture takes up an incredible 70% of all agricultural land, and 30% of the total land surface of the planet. As a result, farmed animals are probably the biggest cause of slashing and burning the world's forests. Today, 70% of former Amazon rainforest is used for pastureland, and feed crops cover m...

100-Mile Diet: Your Body Will Thank You

Image
By Jeff Nield, The Tyee. Posted on Alternet Is eating locally through the winter more a matter of survival than of pleasure or good health? The surprising answer is an emphatic "no." Vancouver-based registered holistic nutritionist Paula Luther is an adherent of year-round local eating for the sake of nutrition. "If we look at what's in abundance right now, we have lots of squash, carrots, things like that, which are actually beneficial at this time of year," she says. These winter foods are rich in beta-carotene, antioxidants, vitamin A -- just the sort of nutrients our bodies need to fight off colds and maintain energy levels for the season. More..

Dire Warning From China's First Climate Change Report

Image
Agence France Presse, posted on Commondreams Temperatures in China will rise significantly in coming decades and water shortages will worsen, state media has reported, citing the government's first national assessment of global climate change. "Greenhouse gases released due to human activity are leading to ever more serious problems in terms of climate change," the Ministry of Science and Technology said in a statement. "Global climate change has an impact on the nation's ability to develop further," said the ministry, one of 12 government departments that prepared the report. In just over a decade, global warming will start to be felt in the world's most populous country, and it will get warmer yet over the next two or three generations. Compared with 2000, the average temperatures will increase by between 1.3 and 2.1 degrees Celsius by 2020, the China News Service reported, citing the assessment. More>

By 2040, Greenhouse Gases Could Lead to an Open Arctic Sea in Summers

Image
By ANDREW C. REVKIN, NY Times New studies project that the Arctic Ocean could be mostly open water in summer by 2040 — several decades earlier than previously expected — partly as a result of global warming caused by emissions of greenhouse gases. The projections come from computer simulations of climate and ice and from direct measurements showing that the amount of ice coverage has been declining for 30 years. The latest modeling study, being published on Tuesday in the journal Geophysical Research Letters, was led by Marika Holland of the National Center for Atmospheric Research in Boulder, Colo. More

The Cost of an Overheated Planet

Image
Steve Lohr, NY Times The iconic culprit in global warming is the coal-fired power plant. It burns the dirtiest, most carbon-laden of fuels, and its smokestacks belch millions of tons of carbon dioxide, the main global warming gas. James E. Rogers, chief executive of Duke Energy and chairman of a leading utility trade group, at an electrical substation in Charlotte, N.C. So it is something of a surprise that James E. Rogers, chief executive of Duke Energy, a coal-burning utility in the Midwest and the Southeast, has emerged as an unexpected advocate of federal regulation that would for the first time impose a cost for emitting carbon dioxide. But he has his reasons. “Climate change is real, and we clearly believe we are on a route to mandatory controls on carbon dioxide,” Mr. Rogers said. “And we need to start now because the longer we wait, the more difficult and expensive this is going to be.” More

Moonbase Planned While Earth is in Peril

Image
According to NBC news today, NASA is in the planning stages of building a moonbase. The moonbase is a step towards a mission to Mars. Though it appears that a base to the moon may be possible, the news broadcast indicated that there is no master plan or funding for a future Mars mission. I for one have never been fond of the NASA program. I have also never bought the marketing ploy that the billions spent on space exploration have brought us wonderful inventions that have greatly improved our lives. I would like to know which of the religions practiced in this country espouse the worship in material goods over the helping of the poor and disadvantaged? I seek knowledge, understanding and enlightenment concerning the ethics that drive us to spend vast public funds on "space exploration" at the expense of our most vulnerable. Is this a shining example of a representative democracy? James E Hansen, the eminent NASA scientist has clearly stated that if we do not DRASTICALLY reduc...

Taming King Coal

NY Times China will surpass the United States as the world's largest emitter of carbon dioxide by 2009, a decade ahead of previous predictions. A big reason is the explosion in the number of automobiles, but the main reason is China's ravenous appetite for coal, the dirtiest of all the fuels used to produce electricity. Already, China uses more coal than the United States, the European Union and Japan combined. Every week to 10 days, another coal- fired power plant opens somewhere in China. What's frightening about this for those worried about the long-term consequences of warming is that nearly all of these plants are being built along traditional lines, burning pulverized coal to make electricity. And what's sad about it is that there's a much cleaner coal-burning technology available. Known as IGCC - for integrated gasification combined cycle - this process coverts coal into a gas before it is burned. These plants produce fewer of the pollutants that cause smog ...

Crude Impact

CRUDE IMPACT is a powerful and timely story that explores the interconnection between human domination of the planet and the discovery and use of oil. This new documentary film exposes our deep-rooted dependency on the availability of fossil fuel energy and examines the future implications of peak oil - the point in time when the amount of petroleum worldwide begins a steady, inexorable decline. Journeying from the west African delta to the heart of the Amazon rainforest, from Washington to Shanghai, from early man to the unknown future, CRUDE IMPACT chronicles the collision of our insatiable appetite for oil with the rights and livelihoods of indigenous cultures, other species and the planet itself. A thought-provoking story of discovery, sorrow, outrage, humor and ultimately, hope. More
