Quantifying climate hypocrisy – the Canada file

An Outside Chance / Bart Hawkins Kreps / 28 November 2018

It was within the first few weeks of the Justin Trudeau administration that Canada surprised most observers by backing a call from island nations to hold global warming to 1.5°C, as opposed to the 2°C warming threshold that had been a more widely accepted official goal.1

Yet according to a new peer-reviewed study2 of countries’ pledged emissions reduction commitments following the Paris Agreement, Canada’s level of commitment would result in 5.1°C of global warming if all countries followed the same approach to carbon emissions. In this tally of the potential effects of national climate commitments, Canada ranks with the worst of the worst, a select club that also includes Russia, China, New Zealand and Argentina.

Two ‘clean growth leaders’ to lead climate advisory panel

CBC News / Salimah Shivji / 24 November 2018

The federal government is turning to a longtime environmental activist and the CEO of the country’s largest community credit union as it seeks advice on how to reach its climate change targets, particularly in the transportation and buildings sectors.

The newly named panel chairs are Steven Guilbeault, co-founder of Equiterre, a Quebec-based non-profit that promotes sustainable agriculture and solutions to environmental degradation, and Tamara Vrooman, president and CEO of Vancity, a member-owned financial cooperative.

Finance Minister Bill Morneau announced the establishment of the panel in his fall economic update on Wednesday. Its mandate has not yet been fully defined, said Guilbeault.

Fourth National Climate Assessment (US)

U.S. Global Change Research Program / 23 November 2018

The Global Change Research Act of 1990 mandates that the U.S. Global Change Research Program (USGCRP) deliver a report to Congress and the President no less than every four years that “1) integrates, evaluates, and interprets the findings of the Program…; 2) analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and 3) analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years.”

The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report (CSSR). Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods.

Municipalities must improve climate change adaptation planning

Waterloo Region Record / James Jackson / 13 November 2018

Mitigation may no longer be enough to prevent climate change impacts from occurring. A UN report released last month found global emissions must drop by 45 per cent before 2030 and reach net zero emissions by 2075 to avoid surpassing the 1.5 C threshold in global temperatures.

Adaptation to climate change varies, but it can include: building flood defences and raising dykes; placing a moratorium on new construction in flood-prone areas; and choosing tree or plant species that are more drought-resistant.

“The gap in adaptation planning is concerning, because cities are more exposed to climate change risk than other levels of government due to high concentrations of people, property, and infrastructure,” [researcher Dave] Guyadeen’s study found.

His analysis also says implementation, monitoring and evaluation is relatively weak in Canada, and that many municipalities haven’t put enough emphasis on stakeholder engagement. Only one province — Nova Scotia — has mandated municipalities to create climate change plans.

The many ways climate change worsens California wildfires

Yale Climate Connections / Dana Nuccitelli / 13 November 2018

California has been ravaged by record wildfires in recent years. 2017 was the state’s costliest and most destructive fire season on record. The Mendocino wildfire in July 2018 was California’s largest-ever by a whopping 60 percent.

Even though California’s wildfire season has traditionally ended in October, the Camp Fire raging in November 2018 is the state’s most destructive on record.

The data tell the story: Six of California’s ten most destructive wildfires on record have now struck in just the past three years.

Earth is in a death spiral. It will take radical action to save us

The Guardian / George Monbiot / 14 November 2018

Only one of the many life support systems on which we depend – soils, aquifers, rainfall, ice, the pattern of winds and currents, pollinators, biological abundance and diversity – need fail for everything to slide. For example, when Arctic sea ice melts beyond a certain point, the positive feedbacks this triggers (such as darker water absorbing more heat, melting permafrost releasing methane, shifts in the polar vortex) could render runaway climate breakdown unstoppable. When the Younger Dryas period ended 11,600 years ago, temperatures rose 10C within a decade.

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.
