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.

CO2 has soared to levels not seen in 800,000 years

Common Dreams / 03 August 2018

As temperatures bust heat records across the globe and wildfires rage from California to the Arctic, a new report produced annually by more than 500 scientists worldwide found that last year, the carbon dioxide concentrations in the Earth’s atmosphere reached the highest levels “in the modern atmospheric measurement record and in ice core records dating back as far as 800,000 years.”

While the most significant jump was the global average for carbon dioxide (CO2)—which, at 405.0 parts per million (ppm), saw a 2.2 ppm increase from the previous year—concentrations of other dominant planet-warming greenhouse gases, methane (CH4) and nitrous oxide (N2O), also hit “record highs,” according to State of the Climate in 2017 (pdf) released Wednesday.

June 2018 ties for third-warmest June on record

NASA Global Climate Change / 17 July 2018

June 2018 continued the warming trend of the past 40 years. According to the monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York, the past month surpassed the 1951-1980 June mean by +0.77°C. It tied with June 1998 as the third warmest June in 138 years of modern record-keeping, with only June 2015 and 2016 (+0.80°C and +0.79°C) being warmer.

The mean temperature anomalies of +0.77°C for both June 1998 and June 2018 cannot be distinguished from each other given the uncertainty of the measurement. However, June 1998 was exceptionally warm at the time due to the then prevailing strong El Niño conditions — about 0.33°C above the trend line of the late 1990s. In contrast, the current El Niño phase is considered neutral. The temperature anomaly for June 2018 is similar to other recent monthly mean temperature anomalies, and lies within the expected range of +0.75±0.05°C.

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.

Changemakers: Embracing hope, taking action …

New Society Publishers

With every news report, the world seems to be careening off the rails. It’s all too easy to slip into despair waiting for co-opted, self-serving governments to act.

The antidote to fear and despair is hope and action. We each hold the power to make personal changes that can drive local changes and cascade into large-scale social transformation.

This is the guidebook for ordinary people who want to create a new society now. The first section explores the idea of transformative change — what it is, what difference it makes, and how it is connected to learning.

The second section explores powerful new stories of everyday people who have challenged traditional understandings of food, shelter, energy, transportation, waste, and economics, and transformed aspects of their lives, their communities, and wider society.

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
