Bill is the founder of the worldwide 350 degrees movement, and he recently gave a presentation at the Embassy theatre in Wellington, which I attended. If you would like to know more google 350.org or google Bill McKibben.
Basically, Bill contends that scientists have calculated that no more than 565gigatonnes (billion tonnes) of fossil fuels can be burned before 2050, if the world wants to limit global temperature rise to no more than 2 degrees as agreed in the 2009 Copenhagen Climate Conference. However, according to the British Carbon Tracker initiative, present known reserves of oil, gas and coal already on company books total 2795 tonnes.
Bill is promoting divestment in fossil fuel companies. Apparently this is a growing movement in the USA, with many churches, universities, local government bodies and some private foundations going down this path.
My issues with this approach is that it ignores the current realities…

We Will Not Run Out of Fossil Fuels
Fossil fuels are formed from the remains of plants and animals that died hundreds of millions of years ago, buried and transformed by heat and pressure. Since these fuels require millions of years to form, for human purposes, the supply of fossil fuels on Earth is effectively fixed. This has led to predictions — such as those based on the “peak oil” theory first proposed by geologist M. King Hubbert in 1956 — that the world will experience an economically damaging scarcity of fossil fuels, particularly oil.
However, new technologies for oil and gas exploration and extraction have upended the notion of fossil fuel scarcity: The limiting factor on humans’ fossil fuel use will not be the exhaustion of economically recoverable fossil fuels, but the exhaustion of the Earth’s capacity to withstand the harmful byproducts of fossil fuel combustion.
For decades, energy…

June 16, 2013—-Producing oil from tar sands is “scraping the bottom of the barrel”, and so it is with the KeystoneXL Pipeline, a pipeline owned by a company named TransCanada, that would double the tar sands currently being transported from the oil fields of Alberta, Canada to the U.S.. The tar sands are under the Boreal Forests of Alberta, home to many species of plants and animals.The Boreal Forest not only cools the earth with its shade, it also plays an important role in preventing global warming, as the trees store and use carbon dioxide (the global warming culprit) in photosynthesis. Under the TransCanada leasing conditions, the company would have the option to lease an area the size of Florida for tar sand production.
Tar sand (or oil sand) consists of sand, sandstone, clay, and water, which are saturated with an extremely thick form of petroleum. These…

(1) CO2 is an important part of the greenhouse that keeps the earth’s average temperature stable. The earth’s atmosphere allows in radiation from the sun, warming the oceans and land. This heat is then radiated back into space with a different wavelength. CO2 absorbs this heat as it is radiated from earth, and retains some of it in the atmosphere. National Geographic has a great explanation of the greenhouse effect at http://greenliving.nationalgeographic.com/description-greenhouse-effect-2501.html . Scientists have proven that the increased CO2 comes from burning of fossil fuels. They can prove this by measuring the percentage of CO2 in the atmosphere that can be carbon dated as very old (so it came from fossils) versus natural carbon that is very new. The amount of CO2 from fossil fuels is the cause of the increase in CO2. See http://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth’s_atmosphere . Current levels of CO2 at 400ppm retains far more energy in the…

What did the Founding Fathers use to power the American Revolution? Pretty much one fuel source: wood. And until the late 19th century, forests remained America’s chief energy source. Since then, it’s been mostly fossil fuels — coal, oil and natural gas — with a little bit of hydroelectric, nuclear and a smidgen of renewables like wind and solar.
That’s the takeaway from a neat infographic put out yesterday by the Energy Information Administration (EIA), the invaluable — and too often underappreciated — statistics arm of the Energy Department. The EIA has been keeping close tabs on U.S. and international energy use going back several decades, but obviously there was no U.S. of A in 1776, let alone an EIA. So Tyson Brown, the analyst who put together the brief, estimated energy use in the colonial era based on population at the time. Wood was just about the only fuel source…

By Lin Smith May 5, 2013—In the past 6 months organizers have begun campaigns on universities and in cities across the U. S. to divest in fossil fuels. Over 300 campuses and 100 cities are now looking at divesting and this movement has spread to Australia, Nederlands, and Britain. University students have stated, “It’s wrong for public institutions to teach and support environmental awareness but yet profit from damaging the environment.” The goal of the Divestment Campaign 350 is to “Challenge individuals and institutions to sell their stock in oil, gas, and coal producing companies because their current business model is leading to global catastrophe.” It’s the opposite of investment. It’s the movement currently taking place across the United States to divest their endowment funds from fossil fuels and place them in investments that support a healthy planet. What is a university endowment fund? Each university has money that is…

If the link between geology, plate tectonics, and climate change seems obscure to you, I would recommend reading the whole thing. However, if you’re busy, let me jump straight to the important bit – what I see as being the implications for humanity today:
Just because it has been much warmer in Earth’s distant past does not change the facts that:
(1) All life on Earth is adapted to the relative climate stability that preceded the Industrial Revolution; and
(2) Most life on Earth will not adapt to the unnatural change now underway unless we stop causing it.
Now we know we are in a hole, I think it would be a good idea to stop digging.

It would seem that economies that reduce heavy reliance on the extraction of natural resources and encourage more sustainable industries are justly considered ‘green’. Often, however, the reality of the so-called ‘green states’ differs significantly from the claims of various labelling initiatives. The process of economic greening is somewhat superficial, and heavily based on the outsourcing of emissions. Alice Fitzsimons examines this in the context of two Australian states, and calls into question the legitimacy of ‘greenness’ of South Australia and other pioneer states.
Australia’s economic prosperity is widely ascribed to its abundant natural resources. The development of the mining, processing, and manufacturing industries that utilise these resources have brought considerable wealth to the nation. The response of resource-based economies, such as Australia’s, to the environmental movement is thus of particular interest. Environmentalism has gathered influence in Australian politics and policy from the 1970’s onwards. At the same time, mining…

They are fully formed works of art, sculpted by nature, ancient yet vibrant.
This year, the sliver of ocean that runs between Newfoundland and Labrador’s Northern Peninsula is teeming with icebergs.
The Canadian Coastguard estimates there are more than 300 icebergs in and around the Strait of Belle Isle — three to four times more than in the previous five years.
The first iceberg we encountered — after our long helicopter flight across the peninsula — resembles a pure, white mountain.
Filled with a sense of child-like wonder, I found myself mouthing an over-used word I generally avoid — awesome.
I soon realize these chunks of glacier, that take up to three years to float from western Greenland to the Strait of…

From CSIRO and “increased CO2 has benefits” department:
Increased levels of carbon dioxide (CO2) have helped boost green foliage across the world’s arid regions over the past 30 years through a process called CO2 fertilisation, according to CSIRO research.
In findings based on satellite observations, CSIRO, in collaboration with the Australian National University (ANU), found that this CO2 fertilisation correlated with an 11 per cent increase in foliage cover from 1982-2010 across parts of the arid areas studied in Australia, North America, the Middle East and Africa, according to CSIRO research scientist, Dr Randall Donohue.
“In Australia, our native vegetation is superbly adapted to surviving in arid environments and it consequently uses water very efficiently,” Dr Donohue said. “Australian vegetation seems quite sensitive to CO2 fertilisation.

The Obama administration, increasingly frustrated by Congressional hostility to any efforts to contain greenhouse gases, has turned to the EPA as a tool for reining in carbon emissions. The agency is developing regulatory standards under the Clean Air Act to reduce carbon pollution on a number of fronts. It is coordinating with the National Highway Traffic Safety Administration to promote new technologies with the goal of reducing carbon dioxide emissions from motor vehicles by 3,100 million metric tons by the year 2025. It is implementing rules requiring minimum amount of renewables in transportation fuel, setting national limits on carbon emissions by power plants, and implementing rules which are expected to bring about a 95% reduction of volatile organic compound emissions from fracking gas wells. Where Congress has refused to act, the Agency has embarked on an aggressive and far-reaching effort to fill the void.
But the agency’s efforts to curb…

When I mentioned to my Gran that we were in an ice age she was immediately worried. “Should I get my boiler serviced?” she wanted to know. With varying reports in the media of global warming having ‘stopped’ and extreme weather events dominating headlines this worry is hardly surprising. But is there a genuine need for concern?
We are currently living through the Pleistocene Ice Age, although thankfully we’re experiencing an interglacial period – a respite from the type of cold periods that spring to mind when talking about an ‘ice age’. But how long will this warm period last?
The historical record suggests that within the Pleistocene (roughly the last 2.5 million years) the onset of warm eras such as the one we’re currently in have been controlled by the Earth’s orbit. On scales of 100,000’s of years the shape of the Earth’s orbit changes, becoming more or less…
