Steadily increasing levels of seawater acidity could re-shape strategic food chains in the polar and sub-Antarctic marine ecosystems earlier than predicted, according to research published in Nature.

 “Within 50 to 100 years, there could be severe consequences for marine calcifying organisms, which build their external skeletal material out of calcium carbonate, the basic building block of limestone,” says Australian scientist, Dr Richard Matear of the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

Atmospheric CO2 is created by combustion.

by Dave Stevens 

Stellar processes excepted, carbon is neither created nor destroyed. As an element it enters readily into combinations with other elements but is not destroyed. Its compounds are sometimes broken down or altered but this does not destroy or create carbon. All ordinary chemical processes are carbon neutral.

Carbon capture and storage is the latest trendy “solution” to the impacts of burning oil and gas. Poli­ticians and many environmental or­ganizations around the world and in Canada are banking on it. The idea is to capture cabon dioxide (CO2) from refineries and coal burning power plants, and pipe it to geologi­cal deposits where it will be injected underground and stored forever.

The best thing we can do with a beetle altered forest is to leave it alone. The beetle pandemic is a problem we can’t fix and anything we do to the forest will just make CO2 emissions worse, especially burning the trees.

Everyone knows we have a carbon dioxide problem. In recognition of this, suppose you wanted to make some lifestyle changes to help reduce these emis­sions and be part of the solution to the climate change issue. Would you use a fuel that quadrupled your CO2 footprint, destroyed habitat, reduced job opportunities and required large government subsidies to produce? 

Paradoxically, that is exactly what the BC government

While governments and industry draft pages of policy to try to clean up the issue of reducing greenhouse gases, the bid for a zero waste approach just got stronger. Stop Trashing the Climate, a report released in June by the US-based Global Alliance for Incinerator Alternatives, reveals that significantly decreasing waste sent to landfills and incinerators will reduce greenhouse gas emissions equal to closing one-fifth of US coal-fired power plants. 

Wasting directly impacts climate change because it is directly linked to global resource extraction, transportation, processing and manufacturing.

For instance, landfills are the largest source of

Like a reck­less gambler, the federal govern­ment’s plan to deal with our emissions of climate-altering carbon dioxide is to put most of our money on an unproven, risky and expensive long shot called “carbon capture and sequestration,” CCS for short. In a pair of October an­nouncements, the Alberta and federal governments com­mitted $1.6 billion to use this untested technology to reduce carbon emissions from an Alberta coal plant and a Shell Oil tar sands upgrader. Billions more are promised. 

Canada puts 600 million tonnes of carbon dioxide into the atmosphere every year. That has to stop. This genera­tion, you and me, must deter­mine what methods and tech­nologies offer permanent CO2 reduction at the scale we need, and do so quickly, safely and at the lowest cost. And we must act on that knowledge as if the future of children’s lives de­pend it because we are shaping the world they will inherit.   

We cannot rely on political and business leaders to make these decisions on their own, as will become evident. What other ways could we reduce our CO2

In 2007, billionaire Sir Richard Branson (chairman of Virgin Group) and Al Gore (former US vice-president) spearheaded a competition called the Virgin Earth Challenge - a contest offering $25 million "to find commercially viable designs to permanently remove greenhouse gases from the atmosphere." As Branson put it, "If we could come up with a geoengineering

A combination of federal government subsidies, changes in the pulp and paper market and questionable energy policies threaten British Columbia forests as they come to be viewed as bioenergy.

Tough times for the pulp and paper industry have called for change, and the industry appears to have diversified to energy production. Pulp mills already have the facilities for energy production, they have been given $1 billion in federal funding for the capital upgrades required, and they have a willing partner with BC Hydro offering lucrative power purchasing agreements. [See "BC's Bio Boondoogle," Watershed Sentinel.] Further, there's a profitable future in saleable carbon credits.

The entire scenario is founded on the use of ‘biomass' as renewable energy and it's become a bit of a gold rush.

Increasing emissions on CO2 are resulting not only in climate change, but also in ocean acidification.

Forty per cent of the world's electricity comes from coal, and 40 per cent of the world's CO2 pumped into the atmosphere is from the burning of coal for electricity. It was a resource on the verge of being considered passe a decade ago, as many countries were phasing
