Death and decay are winning in Canada's vast managed forest lands. And this victory is unleashing a rising flood of climate pollution. Put simply, our forests are dying and being cut down faster than they can grow back.

In 2018, the flood of CO2 pouring out of them reached record levels, at nearly a quarter billion tonnes of CO2 in a single year. That's more than Canada's once biggest climate pollution source — the oil and gas sector — emitted that year.

Researchers map ‘beginning of new ecosystem’ as algae bloom across surface of melting snow [Not The Green We Had In Mind!]

Scientists have created the first large-scale map of microscopic algae on the Antarctic peninsula as they bloom across the surface of the melting snow, tinting the surface green and potentially creating a source of nutrition for other species.

May 13, 2020 - The wheels we humans have set in motion concerning carbon dioxide emissions and climate change are going to take some stopping, and the latest data from Hawaii's Mauna Loa Observatory are another clear indicator of this. Scientists there have logged record concentrations of CO2 in the atmosphere, in line with a steady trend that defies even the widespread and stringent slowdown in global activity as a result of the coronavirus pandemic.

Polluting industries around the world are using the coronavirus pandemic to gain billions of dollars in bailouts and to weaken and delay environmental protections.

A recent landmark study of massive ice loss in Antarctica and Greenland fulfills the “worst case” prognosis, as outlined by the Intergovernmental Panel on Climate Change (IPCC). It’s a nightmare come true, as the impact of global warming on the planet’s most significant/biggest masses of ice multiplied six-fold in only 30 years. It wasn’t supposed to happen so unexpectedly, so suddenly.

The gas plays a powerful role in driving up global temperatures.

A new study published in Nature may have ended a long scientific debate about the key source of rising methane levels in the atmosphere.

It found that methane emissions from human activities — mainly fossil fuels — are probably 25 to 40 per cent higher than previously estimated, while natural sources of methane emissions are up to 90 per cent lower than previously estimated.

All new projects that enable fossil fuel growth are an affront to our state of climate emergency. It is a disgrace Canada is considering them

Dear Prime Minister Trudeau and Deputy Prime Minister Freeland,
