Toronto's Women4Climate Mentorship Programme City of Toronto Are you a woman with a great idea to reduce greenhouse gas emissions in Toronto and/or improve the city’s resilience to climate change? The City of Toronto, in partnership with C40 cities, has launched the Women4Climate Toronto Mentorship Programme to support the next generation of female climate leaders. The programme, presented locally by RBC and supported by EY, will pair 12 participants with a senior professional in their field for a seven-month mentorship and offer networking events, knowledge labs and more. Following the mentorship programme, a pitch competition will award the best female-led climate idea with $20,000 towards professional and idea development. Women age 18 and over with a project or great idea to reduce greenhouse gas emissions and/or improve Toronto’s resilience to climate change are encouraged to apply. Learn more and apply by July 31!

U.S. geoscience programmes drop controversial admissions test Nature Geoscience graduate programmes across the United States are increasingly dropping a controversial standardized test from their admissions requirements. The graduate record examinations (GRE), which was introduced in 1949, aims to measure verbal and quantitative reasoning, analytical writing and critical thinking. In recent years, academic researchers and others have criticized the test, claiming that it unfairly weeds out capable students and restricts the flow of women and people from minority ethnic groups into the sciences.

McIntyre Powder serves as ‘cautionary tale’ about workplace toxins, says researcher Northern Ontario Business Dr. Paul Demers believes McIntyre Powder can serve as a “cautionary tale” about the dangers of exposing workers to toxic substances in the workplace. It was his report, commissioned by the Workplace Safety & Insurance Board (WSIB) and released in early May, that confirmed miners that inhaled the finely ground aluminum powder while on the job between 1943 and 1980 were more likely to develop Parkinson’s disease.

All five Great Lakes are currently trending warmer than normal The Weather Network via Yahoo! News With prolonged stretches of at-times extreme heat, nobody would deny it's been hotter than normal in southern Ontario — and warmth extends to the waters of the Great Lakes. The week of July 6-10th in particular featured one of the greatest anomalies so far this season, with temperatures trending 5-10 degrees above normal. And while surface water temperatures have subsided slightly since, they are still generally trending 2-3 degrees above normal. READ MORE

Drinking water advisory finally lifted Sault Star After almost six years of a drinking water advisory due to the elevated trihalomethane levels (THMs), the municipality has announced the advisory was lifted. Algoma Public Health (APH) issued the advisory in November 2014 after THMs in the Wawa drinking water supply were found to be 112.9 micrograms per litre whereas the Ontario Drinking Water Quality Standards allowable level is 100 micrograms per litre.

The next threat: A high-level nuclear waste dump near Lake Huron voicenews.com No sooner than the Saugeen Ojibway Nation had voted overwhelmingly against Ontario Power Generation's effort to build a deep geological repository for low and intermediate nuclear waste the repository on the lip of Lake Huron, a similar, perhaps more lethal threat has emerged.

Arizona rock core sheds light on triassic dark ages University of Texas at Austin A rock core from Petrified Forest National Park, AZ, has given scientists a powerful new tool to understand how catastrophic events shaped Earth’s ecosystems before the rise of the dinosaurs. The quarter-mile-long core is from an important part of the Triassic Period when life on Earth endured a series of cataclysmic events: our planet was struck at least three times by mountain-sized asteroids, chains of volcanoes erupted to choke the sky with greenhouse gases, and tectonic movement tore apart Earth’s single supercontinent, Pangea.

A new idea on how Earth's outer shell first broke into tectonic plates University of Hong Kong The activity of the solid Earth — for example, volcanoes in Java, earthquakes in Japan, etc. — is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits that Earth’s outer shell (Earth’s “lithosphere”) is subdivided into plates that move relative to each other, concentrating most activity along the boundaries between plates.

On the correlation between solar activity and large earthquakes worldwide Scientific Reports Large earthquakes occurring worldwide have long been recognized to be non Poisson distributed, so involving some large scale correlation mechanism, which could be internal or external to the Earth. Until now, no statistically significant correlation of the global seismicity with one of the possible mechanisms has been demonstrated yet. READ MORE
