Economics and political cues dictate climate change concern for a public that has a remarkably short attention span on the topic, researchers find. Science-based education efforts have 'only a minor effect.'
Weather extremes and efforts to increase scientific literacy have minimal to no impact, the study concluded.
One surprising result of the analysis, said Robert Brulle, the study's lead author and a sociologist at Drexel University in Philadelphia, is the volatility of public opinion.

Half of the 16 scientists who penned a controversial Wall Street Journal opinion piece proclaiming there is "no need to panic" about global warming have ties to either the oil and gas industry or groups dedicated to debunking climate science, a DailyClimate.org investigation has found.
The article, criticized by climate scientists and environmental groups, says that the field of climate science is dominated by opportunists and that "a large and growing number of distinguished scientists and engineers do not agree that drastic actions on global warming are needed."

Carbon emissions from cement are set to grow explosively as developing countries such as India create a "first-world" infrastructure.
Scientists and entrepreneurs are struggling to push alternative technologies out of the lab and onto the street.
As developing countries strive for "first world" living standards, they will be building more sidewalks, roads and housing, the International Energy Agency predicts. In many places, the growth spurt is already underway: Construction in India alone has jumped 10 percent per year for the past decade, according to the World Green Building Council.

Hunted to near extinction in the 19th century, the trumpeter swan is taking advantage of warmer, longer summers to expand its range and numbers - one of the few good news stories of global warming, at least for now.
A warming climate is helping, expanding the swans' summer range northward into habitat never before used in their ancestral boreal forest, allowing populations to flourish, according to new study by Alaska scientists.
"Alaska is warming about twice as fast as the global average. From a swan's perspective, it means greater productivity," says Terry Chapin of the University of Alaska at Fairbanks.

Most media surveys don't look at journalism in India, China, Brazil, Mexico or Africa, where coverage of the issue has recently – and rapidly – increased. But some of the best coverage on climate is now coming from outside Europe and North America.

The applause was raucous. The dancers breathless. But cloaked in the music was a message. Stymied in global climate negotiations, three tiny Pacific island nations used songs and dances to plead for action.
The performers – fishermen, farmers, homemakers and students – traveled 7,000 miles to perform for U.S. audiences.
They tapped their culture and art to tell of their home and plight: While life on their islands centers on fishing and family ties, climate change is intruding, driven by industrialized activities thousands of miles away. Coastlines are eroding and sea level rise is pushing salt water into wells. Families that have lived in the same places for hundreds of years wonder how future generations will subsist.

New data underscores the bleak prospects facing glaciers across the world as emissions continue to rise. In many instances, particularly the tropics, researchers expect the ice serving as key mountain reservoirs will disappear or severely degrade, leaving downstream communities to cope with scarce and unreliable supplies.
Exhibit A is the Andes, where the glacial runoff provides water for hundreds of thousands throughout Peru and Ecuador. Where scientists once thought the region had 10 years to 40 years to adapt to reduced runoff, that time is now up, said Michel Baraër of McGill University in Montreal.

When news broke last week that another cache of emails had been released purporting to show that climate scientists had "cooked the books," parties around the world looked carefully, this time with a doubtful eye. They had a right to doubt. The same ploy won't work again. The science is too robust.
A few things are different this time around. Most importantly, many journalists now realize they were played the fools last time around. They were told that these emails showed scientists "hiding declines in temperature" and conspiring against others. These same media outlets had a lot of work cleaning egg off their face when it became clear that the correspondence said nothing of the sort. In a "fool me once, shame on you; fool me twice, shame on me" manner, the media is largely ignoring these new emails, or they are reporting the real story: The emails are taken out of context, the science is robust and has been upheld by every investigation of the 2009 release, and that climate change is already underway.

Today's IPCC summary on extreme weather makes clear that no one will escape the changes being driven by our greenhouse gas emissions. Change is happening now. Will we act in time?
I helped author the report because I am deeply concerned about what happens to the least advantaged when extreme events hit. As a researcher who has worked with communities impacted by weather disasters, I know how keenly climate-related catastrophes are felt at the most local level - in homes, schools, religious groups and other communities. If people understand the effects of their greenhouse gas emissions, hopefully they will strive to cut these emissions to avoid suffering the consequences of inaction.

A new report concludes that each ton of carbon dioxide emitted in the atmosphere inflicts as much as $900 in environmental harm – almost 45 times the amount the federal government uses when setting regulations. The gap, advocates say, disguises the true value of emissions reductions.
A truer value, according to the analysis, would be equivalent to adding $9 to each gallon of gas. Viewed another way, with the United States emitting the equivalent of close to 6 million tons of carbon dioxide annually, the higher figure suggests that avoiding those emissions could save the nation $5.3 trillion annually, one-third of the nation's economic output.

Preliminary analysis suggests impacts from climate change could run twice as high as previous estimates, giving regulators more firepower to justify emissions-cutting regulations.
Models used to generate current cost impacts contain gaps and, in some cases, outdated assumptions. As those models are refined and updated, they show greater economic harm as global temperatures rise in response to greenhouse gas emissions.
"The big question is how accurate are those models," said Martin Weitzman, a Harvard University economics professor. "There's a lot of fuzziness to them."
Not all economists agree. But a lot is hanging on the outcome.

Our planet's 6.8 billion people include 1 billion hungry and 1.6 billion overweight, and scientists' best predictions have the population rising to 9 billion by 2050 before leveling off. How will we feed so many people without utterly ravaging the Earth?
Here's the dilemma: As people improve their lot, first they start consuming more food, primarily grains and tubers, and then diets shift to energy-rich vegetable oils, sugars, and meat. Raising these foods on large scales - particularly meat - requires more land, water and energy, and it creates more pollution than grain crops or veggies alone.

Shifting freight from trucks to barges could cut U.S. fuel consumption - and provide a big economic boost. But domestic political hurdles block a path being exploited by China, India and Europe.
Among the long-standing obstacles to such a transition, the Merchant Marine Act of 1920 imposes a bit of industrial protectionism that critics contend has outlived its usefulness.
And ship emissions - largely unregulated - are the largest and only growing source of air pollution in many port cities.

After spiking upward in response to the Copenhagen talks and 'climategate' uproar, media coverage of climate change has plummeted to levels last seen in 2005, according to analysis of Daily Climate's archives and other databases.
Despite the trend, some outlets and reporters remain prolific. Reuters lead the pack, publishing 1,683 stories last year - 4.6 stories a day. The New York Times had 1,116; the London Guardian, 941; the Associated Press, 793.
But for network news and other mainstream outlets, the trend was down, down, down.

On the edge of one of the planet's most ice-covered regions, an Alaska glacier is ignoring all climate signals as it advances to the sea. Scientists aim to find out why - and what it means for sea levels around the world.
As the Yahtse glacier advances, it is also thinning, underscoring the mystery behind exactly how tidewater glaciers change over time. Recent research has fingered the ocean as a trigger. Now a team of University of Alaska scientists are investigating what happens when an advancing glacier meets a warmer ocean.

It felt like a sucker punch. Someone had been on our land, cutting trees, heaping up unsightly brush piles, hauling off timber. "My propane bills killed me last winter," offered our neighbor - the culprit. In a carbon-constrained, resource-pinched world, is this our future?
All night, camped amidst the piles of brush, I stewed. I pictured this man working at his leisure, waving at the trucks passing by, stopping to have lunch, sitting on a freshly cut stump, mentally calculating the bills he wouldn't have to pay.
Another thing kept me awake, a foreshadowing of things to come. I thought about the actions people will be driven to by the ripple-effects of climate change and the gathering desperation for cheap, sustainable fuels. What acts will erupt out of the desperation to heat homes, power vehicles, feed families when, for example, cheap oil is no longer cheap, or even available? Never mind the mad scramble from rising oceans, horrific storms, and abrupt climate shifts.

The black metal barrier halted all progress across the four-lane highway, and a phalanx of police emphasized the point: Nobody was getting through. It's a tradition as old as the UN's climate talks themselves - concurrent forums and protests giving voice to those shut out of the opaque official process.
This year three separate forums are lifting that voice. They are centered on a theme - "change the system, not the climate" - and have focused on climate justice, the principle that the globe's poorer nations be accorded full participation and consideration in treaties that have historically been shaped by and, they claim, favor wealthier nations.

New and noteworthy from Daily Climate's news desk. This week: Refinery emissions could double, the Cancun climate talks get 'crowdsourced,' and New York's biggest music video production studio goes solar.

Tidal power may be destined to remain no more than a niche player in the United States' energy portfolio, but the low-carbon energy source has one advantage over wind and solar: It's as dependable as the moon's phases. Investors and public utilities are taking notice.
tidal power is garnering increasing attention as a niche supplier of renewable alternative energy in Washington, Maine and Alaska. The tides, some say, have the potential to light five percent of the nation's homes - nearly nine gigawatts of generating power.

As the Obama Administration prices climate change impacts to help justify emissions limits, it encounters a fundamental problem: Many of the biggest disruptions are impossible to value.
What's the price of giving Sweden the climate of Spain?
I'm loathe to use the numbers derived so far by the working group to evaluate whether or not to limit greenhouse gas emissions.
Why? Because in addition to all the uncertainties, there is no way to capture many aspects of the cultural, social, historical and ecological characteristics that we all value and that will be torn apart by global climate disruption.

Faith communities around the world are taking action - both personal and political - as the moral implications of climate change become more apparent.
While politics is split on climate change and governments worldwide have failed to pass meaningful climate legislation, faith communities are becoming a powerful force in the transition to green energy. By focusing on values rather than politics, they are transcending partisan pigeonholes and taking care of what they see as God's creation, and the people - particularly the poor - who depend on it.
