August 23, 2015 - I'm listening to cicadas outside my apartment window this morning. The steady high-pitched buzz saw singing that often is mistaken by those who are uninformed for the sound of electricity passing through wires. On my morning walks these past few weeks with Maya, my red miniature poodle, it has been hard not to notice cicadas.
August 21, 2015 - If we could directly harvest carbon dioxide (CO2) from the air and separate and capture the carbon while converting what's left to oxygen then that would really be a technology breakthrough of consequence in our fight against global warming. Sounds like science fiction? Well it's not.
August 19, 2015 - I am often asked by readers if it is worth putting solar panels on the roof of their homes. Here in Toronto solar powered houses are few and far between.

August 14, 2015 - If you live in Canada it sometimes is hard to believe that our world will see an almost doubling of population between the beginning and end of the 21st century. That's because the population growth being experienced globally is not reflected locally in this country.
August 13, 2015 - Whatever we are doing to the atmosphere by adding greenhouse gases will take centuries to repair. But the damage to the ocean makes these atmospheric perturbations look like a sideshow.
August 10, 2015 - Developers of new beach resorts in tropical locations are very familiar with mangroves and they hate them because they take up valuable beachfront real estate. But hating mangroves makes little sense in a world facing many environmental challenges because these trees perform an amazing series of functions.
August 7, 2015 - One trillion is a big number. And when it comes to carbon dioxide emissions it represents what scientists believe is the absolute limit of that gas in our atmosphere. One trillion translates to a peak of 450 parts per million (ppm).
August 4, 2015 - Yesterday the President of the United States released the revised Clean Power Plan with a focus on fossil-fuel burning power plants. Why that focus? Because these power plants are the largest carbon dioxide (CO2) emitters in the U.S. contributing 31% of total greenhouse gas (GHG) emissions.
August 2, 2015 - Tomorrow the United States will announce regulations to cut greenhouse gas (GHG) emissions from power utilities nationwide.
