Climate change report: Expect warmer and wetter Ottawa, shorter winters

The National Capital Commission (NCC) and the City of Ottawa commissioned the report to improve the region’s resilience to extreme weather events and other impacts related to climate change. The NCC approved a five-year sustainability plan back in 2018, and Ottawa city council officially declared a climate emergency in the capital last year.

The report projects that, assuming global carbon emissions continue to grow at the current pace, Ottawa will likely see average temperatures 1.8 C warmer in the next three decades as compared to the study’s baseline time period of 1981-2010.

Two-sided solar panels that track the sun produce a third more energy

Double-sided solar panels that tilt based on the sun’s position could boost the amount of energy collected. The two approaches existed independently before, but researchers have now looked at the effects of combining them.

Carlos Rodríguez-Gallegos at the Solar Energy Research Institute of Singapore and his colleagues found that double-sided solar panels that track the sun would produce 35 per cent more energy and reduce the average cost of electricity by 16 per cent.

Heat-trapping carbon dioxide in air hits new record high

KENSINGTON, MD. – The world hit another new record high for heat-trapping carbon dioxide in the atmosphere, despite reduced emissions because of the coronavirus pandemic, scientists announced Thursday.

Measurements of carbon dioxide, the chief human-caused greenhouse gas, averaged 417.1 parts per million at Mauna Loa, Hawaii, for the month of May, when carbon levels in the air peak, the National Oceanic and Atmospheric Administration said. That’s 2.4 parts per million higher than a year ago.

Even though emissions of carbon dioxide from the burning of fossil fuels dropped by as much 17% in April, it was a brief decline. Carbon dioxide can stay in the air for centuries, so the short-term reductions of new carbon pollution for a few months didn’t have much of a big picture effect, said NOAA senior scientist Pieter Tans.

Atmospheric CO2 levels rise sharply despite Covid-19 lockdowns

Carbon dioxide levels in the atmosphere have risen strongly to a new peak this year, despite the impact of the global effects of the coronavirus crisis.

The concentration of CO2 in the atmosphere reached 417.2 parts per million in May, 2.4ppm higher than the peak of 414.8ppm in 2019, according to readings from the Mauna Loa observatory in the US.

Federal Officials Express Doubts on Post-COVID Recovery Package as Cabinet Seeks Free Consulting Advice – The Energy Mix

No green recovery for Canada. Billions for oil & gas — same old, same old…

Federal government department officials may be throwing cold water on the idea of a green recovery package—or any economic recovery package at all—the Globe and Mail reported last Friday, in a story that focused mainly on the Trudeau government turning to one of the world’s biggest management consulting firms for free advice on its post-pandemic strategy.
