In the past few years, science has lurched closer to envisioning habitable Mars, though at the moment estimates for creating breathable oxygen range from hundreds to 100,000 years in the future, the soil is currently toxic to astronauts, and travel is so unwieldy that scientists have proposed "printing" humans on Mars. Meanwhile, I wondered why not make Earth's increasingly inhospitable deserts greener.[more inside]
Writing for The Guardian, Charles Eisenstein argues that regenerative agriculture is crucial to an effective response to climate change, which in his view includes both technological and philosophical shifts: [more inside]
Three visualizations of CO2 emissions: Here’s a cool way to visualize carbon emissions. New York's carbon emissions - in real time. NASA found a way to visualize the most important process behind global warming.
UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]
The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees as many global leaders have hoped. [more inside]
The prospects of keeping climate change below that (2-degree goal) are fading away. Scientists track carbon pollution both by monitoring what comes out of factories and what winds up in the atmosphere. Both are rising at rates faster than worst-case scenarios that climate scientists used in their most recent international projections.
"Speaking for many scientists and engineers who have looked carefully and independently at the science of climate, we have a message to any candidate for public office: There is no compelling scientific argument for drastic action to "decarbonize" the world's economy. Even if one accepts the inflated climate forecasts of the IPCC, aggressive greenhouse-gas control policies are not justified economically." Link. [more inside]
Forum for the Future, a UK-based non-profit, has produced a series of short videos depicting possible future scenarios for sustainable urban mobility. Titled "Megacities on the move," the series explores "how we will live and travel in the cities of 2040". The four scenarios are (links to Vimeo): Planned-opolis , Communi-city, Renew-abad, and Sprawl-ville. [more inside]
The Australian Government has committed to a price on carbon from 1 July 2012, prior to a likely full emissions trading scheme within three to five years. The Opposition are outraged, predicting a people's revolt. This should clearly define the next election.
With the climate bill dead and blame portioned, Ezra Klein asks what happens when congress fails? He concludes that "regulations to reduce carbon emissions are alive and well. The Environmental Protection Agency can attack carbon as a pollutant, and the Obama administration's announcement that efforts to hamstring the EPA will be vetoed suggests that they mean to do exactly that."

Whales are the largest animals on the planet, and when it comes to storing carbon, they act like trees in a forest. A new study suggests that industrial whaling, over the past 100 years or so has released as much carbon into the atmosphere as "burning most of Oregon's forests, or driving 128,000 Hummers for 100 years."

Sucking CO2 out of the air has long been a holy grail for solving global warming; Richard Branson has promised $25m to anyone who succeeds. Of course it's already been done, but the amount of energy required doesn't make it net carbon positive. Now a team in Arizona, led by Klaus Lacknet under the company of Global Research Technologies, says it has made a significant breakthrough that massively reduces the amount of energy required - the "project has reached the stage where it is quite clear we can do it." The planned prototype, which will be finished in two years, will cost $200,000 USD, be smaller than a shipping container and be capable of eliminating around 1 ton of CO2. Even if it works many hurdles remain but it portends a cooler future for air-capture technology.
"So by this analysis dead-tree magazines have a smaller net carbon footprint than web media. We cut down trees and put them in the ground. From a climate change perspective, this is a good thing" explains Chris Anderson, Wired Magazine's editor-in-chief. While some decry this type of carbon footprint accounting as "cheating", the paper industry has lately been eager to convince the public that they are carbon-neutral.
CARMA, released today, is a map/database that shows the carbon emissions of more than 50,000 power plants and 4,000 power companies in every country on Earth, showing not only the worst but the best. Find out how much CO2 comes from electricity plants in a particular city, county, congressional district, company, town, ZIP code, or an individual plant.
