Trees and lengthy drought

The Edible Garden / Edythe Falconer / September 2018

Large trees shelter humans, understorey trees, shrubs, flower beds and vegetable gardens. Besides providing shelter, shade and privacy, trees are psychologically beneficial. And trees hold soil in place. In order to provide all of these benefits, a tree must take its own fair share of moisture and nutrition from the soil it grows in. In dry times they may compromise the welfare of other trees and plants within their growing space as they reach out for what they need. The root systems of large trees are vast.

How should we face the challenge of climate change?

Al Jazeera News / 14 September 2018

Much of the world’s attention this week has been focused on two powerful storms: Hurricane Florence in the United States and Super Typhoon Mangkhut in the Philippines.

The signs of climate change are everywhere, and what were once rare forces of nature are becoming almost regular events.

The Atlantic hurricane season lasts longer, and the storms are more powerful than they were a generation ago.

Across the continent, wildfires in California have burned one million acres (404,685 hectares) of land this year. Experts say the US wildfire season is 87 days longer than it was 30 years ago.

Europe has just come through a summer of record heat that saw wildfires break out above the Arctic circle.

Record rainfall in Japan triggered landslides that smashed homes and forced evacuations. That was followed by two weeks of severe heat.

But what can we do to tackle climate change?

Hot enough for you?

David Suzuki Foundation / David Suzuki, Ian Hanington / 22 August 2018

If you follow climate news (and you should), you’ve likely heard of the global warming “hiatus.” In attempts to keep the world hooked on diminishing reserves of polluting fossil fuels, climate science deniers seized on that phenomenon to claim the warming they once argued didn’t exist stopped. Others took up the false claim out of ignorance and fear.

Global warming didn’t stop. Quite the opposite: it accelerated. According to all legitimate scientific agencies that study climate, the past four years have been the warmest on record, and 2017 was the 41st consecutive year with global average temperatures higher than in the 20th century.

This year is also shaping up to be a record-breaker. But as the old saying goes, “You ain’t seen nothing yet!” That’s because warming didn’t stop. The rate slowed slightly. And that’s over now.

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.

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.

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.
