Looks like a comment on today’s EPA carbon rule, but we do hope you’ll notice that this cartoon is seven years old. Thanks to the artist and the University of Colorado—Boulder for being ahead of their time! (Or not.)
US “clean gas” wells in operation (Irekia-Eusko Jaurlaritza in blogs.lse.ac.uk) Turns out that just about everyone (including President Obama) has been hugely underestimating the methane pollution levels of so-called “clean gas.” The booming American economy now seems to come at a greater cost than we originally thought when we found out that natural gas produces […]
A firefighter pauses at the $2013 Rim Fire in Yosemite National Park, August-September 2013 (Calfire photo on facebook). President Obama released the federal budget for 2015 last week. Overall, it involves the lowest deficit ($514 billion) of his five-year tenure in office and restores some funding cut in last year’s sequester. Parts of the new […]
I remember seeing the first pictures of the North Pole marker underwater last summer, and being immediately, irreconcilably bummed out.
It’s a question that comes up every few “friendly debates” over environmental issues like suburban sprawl, wetland conservation, etc. Which is really better for the environment, cities or suburbs? The answer, of course, depends on who you ask and what you mean by “better”. In the case of climate-altering greenhouse emissions, though, I think we […]
You probably heard wrong. Many in the media neglected to report the story completely. And the graph above doesn’t describe the distortions in coverage very clearly, either. Here’s a simpler statement of the results…. In case you haven’t been following the recent UN report on climate change* in the media, you may be surprised that […]
Officials open the 2013 UNFCCC meetings with determination and louder warnings…. (Photo source: http://ow.ly/qL43P) It’s time for the governments of the world to struggle with climate change policy again. Every year, late in November and early in December, representatives of 195 nations gather for two weeks to try to negotiate global responses to the increasingly […]
New research has shown that rising sea levels could be greatly slowed if certain fast cycling pollutants are cut from the numerous emissions being pumped into the atmosphere. According to the research, published in the journal Nature Climate Change this week, cutting levels of methane, soot, refrigerants, and gases that lead to the formation of ground-level ozone, […]
Climate change deniers are often want to pronounce the current trends in our climate as being part of a larger cycle of warming. Despite the overwhelming lack of evidence for such a claim, it is always important to look at climate cycles to see where and how they might play a part. New research published in […]
Understanding the carbon cycle is a vital part of understanding how our planet will react to a continually warming planet, especially because that warming is caused by increasingly high levels of carbon dioxide in the atmosphere. One tantalisingly elusive aspect of the carbon cycle is the carbon stored deep in the Earth’s mantle. “We are […]
A team of scientists from Britain, Russia, Mongolia, and Switzerland have released a report which finds that evidence obtained from Siberian caves suggest that a global temperature rise of 1.5 degrees Celsius could result in permanently frozen ground end up thawing across a massive swathe of Siberia, threatening a release of carbon dioxide. Such a […]
Republicans don’t want taxes at all, whereas Democrats want to tax everything. It might be an oversimple explanation but it’s definitely going to be right more than it’s wrong. It’s also a good indicator of your allegiance when you hear that US Senators Barbara Boxer and Bernie Sanders have proposed a tax on carbon emissions. The […]
Permafrost covers almost a quarter of the northern hemisphere, and according to recent calculations contains 1,700 gigatonnes of carbon – that’s an amount twice what is currently in our atmosphere. A new report released by the UN Environment Programme (UNEP) entitled ‘Policy Implications of Warming Permafrost’ warns that the release of this permafrost carbon could seriously amplify […]
In an attempt to determine the density of our planet’s core, scientists have attempted to simulate Earth’s formation, and found that Earth’s core contains the largest reservoir of carbon on the planet. Or should we say in the planet … I’m sorry. I’ll shut up now.
Researchers have found that previous estimates about the total mass of life on our planet have been a little too generous, having to decrease the estimate by one third. The study behind the discovery was published in the current online issue of the journal Proceedings of the National Academy of Science and was led by Dr. Jens […]
British and Australian researchers working on data collected over a ten-year period from robotic probes wandering around the Southern Ocean have discovered an important method of how carbon is drawn from the surface of the Southern Ocean to the deeper waters below. The research shows that carbon is not drawn down uniformly by the ocean […]
We're At 400 Carbon PPM Now. Thank You To The Climate Change Trio Of Fossil Fuels: Oil, Gas, And Coal.
Scientists with the National Oceanic and Atmospheric Administration have recently measured levels of CO2 in the atmosphere at 400 parts per million. This is the first time in 800,000 years this has happened on planet Earth.
The global levels of carbon dioxide emissions from fossil-fuel combustion reached a record high of 31.6 gigatonnes (Gt) in 2011, only 1 Gt beneath the necessary levels required to keep global temperatures to a 2°C increase. The figures are part of the preliminary estimates provided by the International Energy Agency (IEA) released Thursday. Global […]
Scientists from the Woods Hole Oceanographic Institution (WHOI) have concluded a study to measure levels of carbon at various levels in the Arctic Ocean, providing a baseline for further understanding. The study was recently published in the journal Biogeosciences. It provides data that will help researchers in the future as they try to better […]
A new study shows that tropical vegetation contains 21 percent more carbon dioxide than previous similar studies had suggested.The study produced maps of carbon storage of forest, shrub lands, and savannas in the tropics of Africa, Asia and South America. Published in the journal Nature Climate Change, the study was conducted by scientists from Woods […]
Human land use of the Amazon basin has begun to change the regional water and energy cycles, says a new report, which also notes that continued interaction between deforestation, fire, and climate change have the potential to drastically alter carbon storage, rainfall patterns, and river discharge on an even larger basin-wide scale. All of these […]
The massive levels of greenhouse gasses left in the atmosphere as a result of human burning of fossil fuels is liable to disrupt normal patterns of glaciation say scientists in a new study. If humans had not arrived and interrupted things, science tells us that the Earth’s current warm phase would have given way to […]
Not for as long as mercury and other toxic pollutant standards have been delayed in the U.S. (21 years), but for about 14 years, regulation of international airline carbon emissions has been delayed. Well, after about 10 years, the E.U. got fed up with waiting around and decided it needed to take action unilaterally. While […]
Climate change is expected to increase the frequency and severity of drought in many of the world’s peatlands which, in turn, is liable to release far more carbon dioxide than had previously been assumed. This new discovery comes as a result of a report published in the journal Nature Geosciences by Dr Nathalie Fenner and […]
Following the initiative of Prime Minister Julia Gillard, Australia’s Parliament passed a plan to cut carbon to 5 percent below 2000 levels by 2020 this week.
As drafted, Australia’s 500 leading greenhouse gas emitters will pay $23 (AUS$1 = US$0.99) for every ton of carbon they emit. The carbon pricing is set to take effect next July, assuming the Senate agrees in November, as expected.
There have been hopes in the scientific community that as the increased levels of carbon dioxide in the atmosphere warmed the planet’s climate, the forests would grow and increase their carbon storage capacity. But new research suggests that another factor – increased litterfall – may turn about turn about any increased carbon storage.
Enacted in 1993, the Northwest Forest Plan consists of a series of federal policies and guidelines which govern the use of federal lands in the Pacific Northwest. Researchers have just concluded, however, that as a result of these same guidelines – which were initially introduced in an effort to conserve old growth forests and preserve species like the northern spotted owl – protection of the land increased carbon sequestration as well.
“The ocean is taking up less carbon because of the warming caused by the carbon in the atmosphere.”
Many studies have shown that people who live in the city help the environment by having a much smaller carbon footprint than those living in the country. However a new study shows that this is not the case, and that no matter where you live, your carbon footprint will be pretty much the same.
The Paleocene-Eocene Thermal Maximum (PETM), which took place some 55.9 million years ago, is the best analogue that we currently have for understanding what might happen if greenhouse gas emissions are not curtailed soon, and according to a new study, the rate of release of carbon dioxide into the atmosphere today is 10 times as fast when compared to the PETM.
Yes, it’s more complicated than that — this was a hard story to come up with a title for — but this is the gist of a new proposed plan (or several new plans) for balancing the nation’s budget that would ALSO, by chance, cut CO2 emissions considerably, thus slowing or stopping human-caused global warming and saving us trillions of dollars in damage and healthcare costs in the process. Here’s a little more…
