Replacing wood stoves is essential but won't solve the indoor air pollution epidemic on its own.
Humanity is destroying Earth’s ability to support complex life. But coming to grips with the magnitude of the problem is hard, even for experts.
The Paris Agreement desperately needs to be updated. Currently the big exporters take no responsibility for the emissions created when those fossil fuels are burned overseas.
The pandemic, along with other recent trends such as the shift towards clean energy, have placed us at a crossroad: the choices we make today can change the course of global emissions.
Joe Biden has sweeping plans for a clean energy revolution. Congress will be a big speed bump, but it can't block everything.
Biden's strong climate change position doesn't appear to have hurt him in the key swing state of Pennsylvania or in the general election more broadly. Here's what it means for Canada.

Recent industry reports indicate that we may be approaching peak global demand for oil. If that's the case, the federal Conservatives may need to rethink their electoral strategy.
Life cycle assessments of electric vehicles show that they cannot fully eliminate the greenhouse gas emissions of personal travel. We also need bikes, buses and trains to solve our climate problems.
What do ammonium nitrate and iodine have in common? Both substances are of immense service to humankind, and the history of their discovery is closely linked to that of the production of explosives.
Molina, who died on Oct. 8, 'thought climate change was the biggest problem in the world long before most people did.' His research on man-made depletion of the ozone layer won the 1995 Nobel Prize.
It's encouraging that the federal government recognises its role in industry policy. But its choice to support some technologies is disappointing.
The pandemic recession has reduced US energy demand, roiling budgets in states that are major fossil fuel producers. But politics and culture can impede efforts to look beyond oil, gas and coal.
Supercomputing, frequent flying and powering up observatories: astronomy has an enormous carbon footprint.
Canada retooled its economy during the Second World War. We must do so again to confront the climate emergency.
A storm-driven chlorine gas release in a vulnerable community is the type of worst-case scenario that scientists and engineers have warned about for decades.
Geothermal reservoirs supply more than 15% of New Zealand's electricity. The heat energy stored in geothermal fields is vast but not infinite.
We are now at the start of the sixth great wave in economic disruption, driven by renewables, electomobilty and smart-city technologies.
