Thanks to humans, the concentration of planet-warming carbon dioxide in the atmosphere is now 50% higher than before the industrial era. These gases are raising Earth’s temperature.
The war in Ukraine threatens to turn back the clock on Russia’s climate progress, with some calling on the country to leave the Paris Agreement and roll back environmental regulations.
Drained peatlands contribute five per cent of global carbon emissions. Paludiculture, or agriculture on wet peatlands, protects peatlands and allows farmers to maintain their livelihoods.
When groundwater comes to the surface, sunlight and air convert organic molecules to greenhouse gases. That’s going to be a problem as we will need this water more as the world warms.
It is time to acknowledge and address the rapid shifts in Canada’s oceans. To meet this challenge, Canada’s marine conservation toolbox — starting with the Oceans Act — needs an overhaul.
Canada’s greenhouse gas emissions decreased by only one per cent between 2005 and 2019. A new climate plan charts the path to deep cuts in carbon emissions in only eight years.
