When Paris's Notre Dame caught fire on April 15, the flames threatened more than eight centuries of culture and history. The fire evoked shock, horror and grief worldwide. While the cathedral burned, French President Emmanuel Macron expressed determination to rebuild what the French regard as a sacred site.

It's heartening, in the midst of the human-caused sixth mass extinction, to find good wildlife recovery news. As plant and animal species disappear faster than they have for millions of years, Russia's Siberian, or Amur, tigers are making a comeback. After falling to a low of just a few dozen in the mid-20th century, the tigers now number around 500, with close to 100 cubs — thanks to conservation measures that include habitat restoration and an illegal hunting crackdown.

Weather and climate aren't the same. It's one thing for people who spend little or no time learning about global warming to confuse the two, but when those we elect to represent us don't know the difference, we're in trouble.
For a U.S. president to tweet about what he referred to as "Global Waming" because parts of the country are experiencing severe winter conditions displays a profound ignorance that would be embarrassing for an ordinary citizen, let alone the leader of a world power.

Global warming isn't a partisan issue—or it shouldn't be. The many experts issuing dire warnings about the implications of climate disruption work under political systems ranging from liberal democracies to autocratic dictatorships, for institutions including the U.S. Department of Defense, World Bank, International Monetary Fund, and numerous business organizations and universities.
In 1988, when NASA scientist James Hansen reported to Congress that evidence for human-caused global warming was near undeniable, conservative politicians including the UK's Margaret Thatcher, U.S. President George H.W. Bush and Canada's Brian Mulroney agreed that action was needed. In my home province of British Columbia, a right-leaning government, the British Columbia Liberal Party, introduced a carbon tax in 2008.

During the holiday season, people often drink toasts to health. There's something more we can do to ensure that we and others will enjoy good health now and into the future: combat climate change.
In a 1965 speech to members, American Petroleum Institute president Frank Ikard outlined the findings of a report by then-president Lyndon Johnson's Science Advisory Committee, based in part on research the institute conducted in the 1950s.
Canadian climate change opinion is polarized, and research shows the divide is widening.The greatest predictor of people's outlook is political affiliation. This means people's climate change perceptions are being increasingly driven by divisive political agendas rather than science and concern for our collective welfare.

People in Canada discard about 57 million plastic drinking straws every day. In my hometown of Vancouver, we toss out 2.6 million disposable cups every week. It's a global problem. Plastic products are choking landfills and waterways and causing devastation in the oceans. In 2014, scientists even found a new kind of stone in Hawaii, made of sand, shells, coral, volcanic rock and plastic.
Over the past few months, heat records have broken worldwide.
In early July, the temperature in Ouargla, Algeria, reached 51.3°C (124.34°F), the highest ever recorded in Africa! Temperatures in the eastern and southwestern U.S. and southeastern Canada have also hit record highs. In Montreal, people sweltered under temperatures of 36.6°C (97.88°F), the highest ever recorded there, as well as record-breaking extreme midnight heat and humidity, an unpleasant experience shared by people in Ottawa. Dozens of people have died from heat-related causes in Quebec alone.
AstroTurf looks and feels like grass—in an all-too-perfect way. But it's not grass.
Now the well-known artificial turf's brand name has taken on a new meaning, referring to purported "grassroots" efforts that are actually funded and supported by industry and political entities.
A warm summer day, a cold drink and fish on the grill. It doesn't get much better. But how do you know if your fish is sustainable? It can be a challenge—especially considering SeaChoice found just 11 per cent of seafood available in Canada in 2016 was rated as a "best choice." Many retailers have sustainable seafood policies, but how good are they?
