A seismic line (petroleum exploration corridor) traverses a wetland in northern Alberta.
Petroleum exploration in Alberta has disturbed more than 1,900 sq. km of wetlands in Alberta, boosting emissions of methane: a potent greenhouse gas.
Carbon offsetting is one way of doing it – but sometimes the simplest methods work best.
Very beautiful, and useful too.
An expert explains all the wonderful ways the atmosphere protects life on Earth.
It can be tempting to point fingers, but people with other priorities aren’t necessarily bad.

In the end, climate policy didn't swing the federal election, and for those on the losing side it can be tempting to play the blame game. But listening and respect are much better ways to move forward.
The Cape Grim observatory, home of the ‘world’s cleanest air’… and rising greenhouse gases.
Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.
The principles that drive financial markets emphasize short-term profits at the cost of long-term benefits.
Investors are increasingly concerned about climate change, but for the markets to deploy their full capacities, the dominant principles that guide them need to be revised.
Farm ponds can act as greenhouse gas sinks.
New research finds that farm ponds actually capture nitrous oxide; this finding can be useful in combatting climate change.
The exploitation of fossil fuels emits CO₂, the main cause of global warming.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
The Rhenish Brown Coal Field in Germany. Germany is one of 18 developed countries whose carbon emissions declined between 2005-2015.
Reducing emissions doesn't have to conflict with a growing economy, as these 18 developed nations show.
While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.
Corn cobs dried up after a drought in eastern France in 2015.
The climate issue cannot be considered less urgent than the social or economic crisis.
Whether to attending a conferences or giving in to a meeting, the global research community is keen on air travel. That’s a habit that needs to change.
Architects see buildings as a possible solution to the climate crisis.

Buildings are responsible for 40 per cent of energy-related carbon dioxide emissions worldwide. Efforts to reduce emissions should no longer be voluntary.
Steel mills, like this one in Hamilton, Ont. emit greenhouse gases. Ontario must reduce its emissions from 161 megatonnes to 143 megatonnes by 2030.
Ontario's new environment plan scores poorly on conservative ethos.

The country's carbon emissions should level off again soon.
Economists have searched for the mythical balance between the cost of climate action, and the future cost of doing nothing.
For decades, economists have pondered the 'social cost of carbon' - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.
Working together, people and technology companies can make a lot of progress.
Amazon, Facebook and Google have lofty goals for their effects on global society. But people around the world are still waiting for the positive results. Here's what the tech giants could do.
The Internet of Things could improve quality of life, but it will also consume vast amounts of electricity and boost greenhouse gas emissions.
The Internet of Things is contributing to climate change. Innovation in computer design could help mitigate the problem.
Lithium batteries offer renewable energy electricity power storage.
High quality Li-ion batteries could help Africa optimise renewable energy.
The basic principle of ecodesign is the concept of life cycle, which aims to take into account end-of-life considerations.
To reduce the impact of its activity on the environment, a company must take into account not only the effects generated by its production, but also the end of life of its products.
