Peat fires will become more common in Canada

CBC News / Sonya Buyting, Emily Rendell-Watson / 01 August 2020

As a result of climate change, peatlands are becoming hotter and drier, and thus more susceptible to the type of blazes we’re witnessing in Siberia.

“We now know that peatlands around the world, from the Arctic all the way to the tropics, are indeed vulnerable to wildfire,” said [ecosystem ecologist Merritt] Turetsky.

Calling peat-burning one of the most important environmental topics, Turetsky said “the Arctic literally has a fever and is literally on fire.”

Peat fires not only release CO2, but other, more potent greenhouse gases such as methane, as well as particulate matter, “which is the stuff that gets into our lungs, it can cause respiratory disease and asthma attacks,” said Turetsky.

Best and worst case scenarios less likely than thought

The Guardian / Jonathan Watts, Graham Readfearn / 22 July 2020

Doomsayers and hopemongers alike may need to revise their climate predictions after a study that almost rules out the most optimistic forecasts for global heating while downplaying the likelihood of worst-case scenarios.

The international team of scientists involved in the research say they have narrowed the range of probable climate outcomes, which reduces the uncertainty that has long plagued public debate about this field.

Their increased confidence about the sensitivity of the climate should ease the job of policymakers and diminish the scope for scepticism but it is far from reassuring for the future of the planet.

IEA: ‘Green’ recovery would keep emissions below 2019 peak

Carbon Brief / Josh Gabbatiss / 18 June 2020

The world has a “once-in-a-lifetime opportunity” to pour investment into clean energy and create millions of new jobs, according to the International Energy Agency (IEA).

Its “sustainable recovery plan” for the coronavirus pandemic lays out a series of measures that the agency says would ensure 2019 was the “definitive peak” for global emissions.

Launched in cooperation with the International Monetary Fund (IMF), the new report presents a strategy for economic growth that includes mass home renovations, fossil-fuel subsidy reforms, renewables and the expansion of power grids.

More extreme rainfall due to climate change, study confirms

CBC News / Emily Chung, Alice Hopton, Tashauna Reid / 03 June 2020

Warmer temperatures due to climate change lead to wetter air, and we’ve seen more extreme rainfall and flooding across North America. But is there really evidence that the two are related?

Yes, there is.

A new study from researchers at Environment and Climate Change Canada found that climate change has made:

  • Rainfall more extreme.
  • Storms with extreme rainfall more frequent.

Canadians still support climate action: poll

BIV / Jeremy Hainsworth / 28 May 2020

COVID-19’s economic and health challenges have not diminished support for infrastructure changes to create a cleaner Canadian economy, a new poll finds.

Results from the Abacus Data-Clean Energy Canada poll released May 28 found an equal number of those surveyed believed a change to a cleaner economy was possible and that such considerations should come after health and economic concerns.

‘The human fingerprint is everywhere’: Met Office

The Guardian / Jonathan Watts / 27 May 2020

Scientists at the Hadley Centre, which has been on the global frontline of climate monitoring, research and modelling since it opened in 1990, said early theories about fossil-fuel disruption have been proven by subsequent facts.

“The climate now is completely different from what we had 30 years ago. It is completely outside the bounds of possibility in natural variation,” said Peter Stott, a professor and expert on climate attribution science at the centre.

The Transition Framework

Transition Towns are in the forefront of those preparing for the changes ahead. Transitioners understand that the climate-changed future is hugely unpredictable and unstable. They feel keenly the dilemma of our daily life dependence on a dominant economic system that is threatening that very life with its insistence on unending material consumption and use of fossil fuels.
