Space: the crowded frontier

Canadian researchers warn that new constellations of thousands of small communications satellites pose a growing hazard in low earth orbit, threatening other satellites, astronauts and possibly even the planet’s climate. [node:read-more:link]

Disaster bills rising rapidly

The cost to the federal government of dealing with natural disasters would indicate that Canada continues to be seriously affected by climate change. Public Safety Canada says the amount was $309.5 million in the 2018-2019 fiscal year compared with $494.9 million a year earlier and $485.8 million in 2016-2017. The average in the five previous years was $360 million, which was triple the average in the five years before that. [node:read-more:link]

Antarctica warming continues

Researchers say they logged an unprecedented temperature of more than 20°C on an island off the northern most point of Antarctica 09 February. The continent itself saw a record 18.3° last week. [node:read-more:link]

Antarctic melting accelerates

Satellite imagery showing extensive Antarctica snow melt over several days in early February has been released by NASA. The images uphold observed surface temperatures which have reached record levels. [node:read-more:link]

Chinese emissions drop noted

Satellite imagery suggests that China’s emissions of nitrogen dioxide by industry and internal combustion engines have been declining, possibly related to a manufacturing slowdown as part of China’s stop the spread of Covid-19. As the epicentre of the viral outbreak, China itself has reported nearly 80,000 cases, but it has spread to more than 50 other countries. [node:read-more:link]

Arctic research effort resupplied

The Russian polar icebreaker Kapitan Dranitsyn has set a record by going further north under its own power to complete a supply run to a multinational expedition adrift in the high Arctic. The expedition is designed to improve scientific understanding of climate change which evidently is accelerating sea-ice melt. [node:read-more:link]

Global climate summit postponed

Arctic mission confirms ice loss

A German year-long research mission in the Arctic has confirmed that permanent sea ice continues to disappear due to global warming. “The ice is disappearing and if in a few decades we have an ice-free Arctic, this this will have a major impact on the climate around the world,” the chief scientist says.

Arctic ice shelf continues to shrink

New satellite imagery of an already fractured ice shelf north of Ellesmere Island shows that an 80km2 section has broken off and then split into two segments which drifted into the Arctic Ocean in late July. Ellesmere was once bounded by extensive shelves covering 8,600kmbut global warming has resulted in continued shrinkage to less than 500km2. [node:read-more:link]

New GHG targets announced

Prime Minister Justin Trudeau said today that Canada will reduce its greenhouse gas emissions by 40-45 per cent from 2005 levels within the next decade. Announced as the U.S. unveiled a planned 50 per cent reduction, Canada’s latest target is higher than the 36 per cent the government says it currently can achieve by 2030 and the 30 per cent goal initially agreed to in the Paris Agreement.

Supreme Court backs federal carbon tax

The constitutionality of the federal government’s carbon tax was upheld today by the Supreme Court of Canada in a split decision. Several provinces had challenged the policy but the majority of the nine judges agreed that climate change is “a threat of the highest order” and a “threat to the future of humanity.” [node:read-more:link]

Security prominent in Biden budget

President Joe Biden’s first discretionary funding request to Congress sets a $1.5 trillion spending roadmap that includes cash funding for the Cybersecurity and Infrastructure Security Agency and a reserve for “information technology enhancements.” Other key elements include funding for two new research agencies focused on health and climate.
