Scientists strive for negative emissions

A Greener Life

Human activity adds more than 50 gigatons of carbon dioxide to the atmosphere each year. New Solid Carbon technology might be able to lock climate-warming carbon dioxide below ocean bedrock. Basalt is a porous rock formed from cooling lava. Large-scale solutions are urgently needed. By Dr Kate Moran.

Delayed harm and the politics of climate change, reconsidered

Legal Planet

But what happens when we achieve the goal of zero carbon dioxide emissions from human actions? Does the climate keep warming, stay the same, or even cool? It turns out this is a critical question for understanding what carbon budgets we have in terms of emissions, if we seek to meet temperature thresholds like 2 degrees Celsius.

The Health, Environmental and Financial Risks of Oil Sands Carbon Capture Projects Need to be Adequately Assessed by Alberta

Enviromental Defense

They are proposing a major carbon capture and storage (CCS) project in northeast Alberta. The project will capture carbon dioxide (CO 2 ) from 13 oil sands facilities in the Fort McMurray, Christina Lake, and Cold Lake regions and transport the CO 2 to the Cold Lake area where it will be injected underground (just south of St.

New Study Finds Low Awareness Among Ontarians About Eco-friendly Technologies that can Cut Energy Bills

Enviromental Defense

Heat pumps, a simple but effective technology, use electricity to remove heat from inside your home to cool it in the summer and pull heat in from outside to heat your home in the winter. Gas is made mostly of methane – a climate-damaging fossil fuel that is over 80 times more potent than carbon dioxide.

A Dangerous Disruption

Legal Planet

Last week, MIT’s “Technology Review” reported that a small startup firm is proposing to spray reflective aerosols in the stratosphere commercially as a climate corrective. They say they have thus far launched two small weather balloons, which each released a few grams of sulfur dioxide gas (SO 2 ) in the stratosphere.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

Responsible for 12 percent of all US global warming emissions from human activities, methane traps significantly more heat per molecule than carbon dioxide, making it 86 times more harmful for the first 20 years after it is released into the atmosphere. Its primary component is methane.

volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone. The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio) and oxygen (20.9%
