A New Way to Assess ‘Global Warming Potential’ of Short-Lived Pollutants

by

Comparing greenhouse gases with each other using GWP* preserves the link between emissions and warming or cooling of the atmosphere. Therefore, GWP* is better suited than GWP100 to assessing whether the world is on track to limit warming to well below 2C.

Tourism Responsible for 8% of Global Greenhouse Gas Emissions, Study Finds

by

Worldwide tourism accounted for 8% of global greenhouse gas emissions from 2009 to 2013, new research finds, making the sector a bigger polluter than the construction industry. The study, which looks at the spending habits of travellers in 160 countries, shows that the impact of tourism on global emissions could be four times larger than previously thought.

Nine Uncomfortable Canadian Energy Facts

by

Hughes, whose reliable research is cited by the likes of Bloomberg, Nature, The Economist and The Tyee, has been analyzing energy trends for industry and government for more than 30 years. Unlike many environmentalists, Hughes does not believe that a transition to renewables or even reductions in greenhouse gases will be seamless, easy or cheap.

Politics versus the Future: Canada’s Orwellian Energy Standoff

by

Industry extracts the lowest-cost, highest-quality, least emissions-intensive fossil fuel resources first. Knowing that fossil fuels will likely be needed for a long time to come, and that producing them is very emissions-intensive, Canada’s current de facto strategy of selling them off at rock bottom prices with declining revenues to government makes little sense.

Stunning New Research Finds Fracking a Major Source of Carbon Pollution in Pennsylvania

by

The evidence is now overwhelming that natural gas is not part of the climate solution, it is part of the problem. A new study finds that the methane escaping from Pennsylvania’s oil and gas industry “causes the same near-term climate pollution as 11 coal-fired power plants.”

Quantifying our Faustian Bargain with Fossil Fuels

by

The climate system will heat well past 1.5 degrees Celsius (°C) and perhaps up to 2°C without any further fossil fuel emissions. That’s the conclusion to be drawn from new research which should also help demystify the rhetoric from the 2015 Paris climate talks of keeping warming to below 1.5°C .

Analysis: Why Scientists Think 100% of Global Warming is Due to Humans

by

The extent of the human contribution to modern global warming is a hotly debated topic in political circles, particularly in the US.During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”. However, the science on the human contribution to modern warming is quite clear. Humans emissions and activities have caused around 100% of the warming observed since 1950, according to the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report.

Hoboken Resolves to Mobilize

by

Last week was a turning point for our movement: the first big win for mobilization on the city level. After a year of work by members of the Climate Mobilization Hoboken, a resolution passed unanimously through the Hoboken City Council on November 1 calling for mobilization to city-wide carbon neutrality by 2027.

Is Greenhouse Warming a Good Pretext for Selling Driverless Cars?

by

The automakers and IT giants are predicting that autonomous vehicles (AVs or “driverless cars”) will play a big role in reducing America’s currently extravagant emissions of greenhouse gases. In this claim (as in the assertion that flying cars will be more energy efficient than helicopters), climate mitigation is serving not as a goal but as a selling point for a lucrative new technology that society doesn’t need.
