More heat, drought and longer fire season in Canada’s future

Montreal Gazette / Anna Junker / 18 August 2018

Heat and drought. A longer fire season with more frequent wildfires and larger areas burned. That’s what’s in store for Canada, especially the prairie provinces, in the coming years, experts say, a situation that is being directly attributed to climate change.

In Canada, 2.5-million hectares — equivalent to about half the size of Nova Scotia — burn every year from wildfires on average. The annual destruction has more than doubled since about the 1970s, where numbers were around one million hectares.

Current projections forecast even warmer, drier conditions across the country, creating the perfect catalyst for more wildfires in the future.

The message of a scorching 2018: Scientists were right

National Post / Somini Sengupta / 13 August 2018

This summer of fire and swelter looks a lot like the future that scientists have been warning about in the era of climate change, and it is revealing in real time how unprepared much of the world remains for life on a hotter planet.

The disruptions to everyday life have been far-reaching and devastating. In California, firefighters are racing to control what has become the largest fire in state history. Harvests of staple grains like wheat and corn are expected to dip this year, in some cases sharply, in countries as different as Sweden and El Salvador. In Europe, nuclear power plants have had to shut down because the river water that cools the reactors was too warm. Heat waves on four continents have brought electricity grids crashing.

And dozens of heat-related deaths in Japan this summer offered a foretaste of what researchers warn could be big increases in mortality from extreme heat. A study last month in the journal PLOS Medicine projected a fivefold rise for the United States by 2080. The outlook for less wealthy countries is worse; for the Philippines, researchers forecast 12 times more deaths.

Extreme temperatures ‘especially likely for next four years’

The Guardian / Jonathan Watts / 14 August 2018

The world is likely to see more extreme temperatures in the coming four years as natural warming reinforces manmade climate change, according to a new global forecasting system.

Following a summer of heatwaves and forest fires in the northern hemisphere, the study in the journal Nature Communications suggests there will be little respite for the planet until at least 2022, and possibly not even then.

Rising greenhouse gas emissions are steadily adding to the upward pressure on temperatures, but humans do not feel the change as a straight line because the effects are diminished or amplified by phases of natural variation.

From 1998 to 2010, global temperatures were in a “hiatus” as natural cooling (from ocean circulation and weather systems) offset anthropogenic global warming. But the planet has now entered almost the opposite phase, when natural trends are boosting man-made effects.

Tips for success in germinating seeds in hot weather

Mother Earth News / Pam Dawling / 27 July 2018

In an earlier post I wrote general themes for starting seeds in hot weather. Here are some specific tricks.

Seed Storage

Viability and vigor of seeds deteriorates when they are stored in warm places, especially if containers are not airtight, and the air is humid. If you have crops you grow in spring and again for the fall, store those seeds in a cool place over the summer.

Chilling lettuce seed can help germination in hot weather. We make a practice of putting our spinach seed in double ziplock bags and putting it in the freezer for two weeks before we attempt late summer sowings. This can trick the seed into germinating better.

The world is hot, on fire, and flooding. Climate change is here.

Grist / Eric Holthaus / 24 July 2018

The worst ravages of climate change are on display around the world.

Wildfires have ripped through towns in Greece, floods have submerged parts of Laos, and heat waves have overwhelmed Japan. These are striking examples of climate change playing out in its deadliest forms, and they’re making the term “natural disaster” an outdated concept.

Heatwave sees record high temperatures around world

The Guardian / Jonathan Watts / 13 July 2018

Record high temperatures have been set across much of the world this week as an unusually prolonged and broad heatwave intensifies concerns about climate change.

The past month has seen power shortages in California as record heat forced a surge of demand for air conditioners. Algeria has experienced the hottest temperature ever reliably registered in Africa. Britain, meanwhile, has experienced its third longest heatwave, melting the roof of a science building in Glasgow and exposing ancient hill forts in Wales.

The World Meteorological Organization (WMO) said the rising temperatures were at odds with a global cyclical climate phenomena known as La Niña, which is usually associated with cooling.

The Transition Framework

Transition initiatives share many of the same goals as other groups, and work collaboratively with a variety of organizations in their local areas. Transition differs in that it focuses specifically on preparing communities for the changes associated with unprecedented resource depletion and transitioning away from fossil-fuel dependency.
