Essays on climate change in canada

But the frequency and severity of extreme weather in recent years points to new instabilities in the global patterns of ocean currents and atmospheric jet streams. More and worse weather extremes can be expected. Even if further greenhouse-gas emissions — notably carbon dioxide — could somehow be stopped overnight, the lingering consequences of atmospheric loadings already in place will send global temperatures higher for centuries, at least.

Even couched in the dispassionate terms of science, the outlook is grim: "Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped. New York City, Shanghai and dozens of other coastal cities that are home to hundreds of millions of people will need massive, expensive protections. It remains unknown whether warming will eventually undermine the vast Antarctic and Greenland ice sheets, sending them sliding into the sea — although, even at vastly accelerated rates, that could take centuries.

The consequences would be sea levels rising by many metres and the disruption of huge, globe-girdling ocean currents such as the Gulf Stream. The report says the "tipping points" in Earth's complex climate system still can't be defined. But, the panel warns, attempts at geo-engineering — the stuff of science fiction like space umbrellas that block sunlight from reaching Earth to cool an overheating planet or new technologies to suck carbon dioxide from the atmosphere and sequestrate it underground — may pose unfathomable risks even as they offer ways to remediate inevitable damage.

Whether halting the heat will come too late for many species — from coral reefs cooked by hotter water to polar bears doomed by a lack of sea ice — is also unknown.

Essay on We Must Prevent Climate Change -- Global Warming Essays

For example, many zero waste restaurants popped up that used animal products created in-vitro, and instead of city lights, the streets began to use bioluminescent bacteria that did not require electricity. The transportation sector was vastly improved so that people could essentially go from one end of a city to another using nothing but bikes, elevated, aboveground and underground hydrogen trains or frictionless vehicles.

By radically changing the way it fuels our homes and our economy to making large improvements to our cities and businesses, it has demonstrated its capacity in tackling this challenge along with other countries. In fact, many other countries followed in its footsteps and adopted its drive for innovation and problem-solving.

I clap my hands twice to stop the music and head to the washroom, where I get undressed and take a steam shower. After five minutes, the water jets stop and the fans dry me with warm air. I get ready and go downstairs.

Outing with Sami downtown at 10 a. I enter the kitchen and make myself a salad of locally grown blueberries, strawberries, and cherries. I savour my breakfast, brush my teeth, and leave to pick up my grandson.

After walking a half-hour, I find young Sami in the doorway waiting for me. I signal to his mother, and we head toward the train station.

Most ran on gas. They were noisy and polluting. But fortunately, the government invested heavily in finding renewable energies. We get to the station after 15 minutes, I buy our tickets and we board the maglev magnetic levitation train. Sami takes the window seat and I sit beside him.

How fast are we going now? Before, trains were much slower, polluted more, and were less efficient. Sami looks out the window and notices that the urban landscape has become a magnificent forest. Forty years ago, hundreds of forests were planted where there were once cattle ranches. We get off the train and explore the city centre. The time passes quickly and it is soon lunchtime. Sami is hungry, so we head for the nearest restaurant, Vegemiam.

I order two vegetarian hamburgers and grilled potatoes. We sit down and Sami devours his meal. Watching him eat, my memory takes me back 60 years, when I was 8 years old and ate ground beef hamburgers and French fries. Industrial livestock farming emitted more greenhouse gasses then the entire transportation sector, and discarded frying oil destroyed aquatic ecosystems. Thanks to a national awareness campaign and government taxes on the meat industry, we were able to dramatically reduce our emissions of pollutants.

I remember like it was yesterday when I went with my friends to celebrate the th anniversary. Back then, the future seemed dark, and humanity was heading straight for its own destruction. Environmentalists were sounding the alarm, but we turned a deaf ear.

Our lifestyle was focused on consumption and profit, to the detriment of the planet. All the melting glaciers, droughts, and species extinctions should have awakened our consciences. Today, thanks to our engagement and perseverance, we have managed to change directions. We have reduced our consumption of water, innovated our means of transportation, replanted our forests, and changed our eating habits to reduce our ecological footprint on earth. Our efforts stopped the hemorrhage of species extinctions and stabilized climate change.

Je rentre dans la cuisine et me sert une salade de bleuets, fraises et cerises locaux. Sami a faim, on se dirige donc vers le resto le plus proche, Vegemiam. The fight to prevent climate change was successful, based on two international fronts; energy and agriculture. Each had their winners and losers. The energy front was based off the transition between fossil fuels to renewable sources.

Essentially, moving away from fossil fuels was a painful transition, both economically and politically.

In , Canada had one of the most emissions intensive economies in the world, and had earlier dreamed of using its vast Athabasca oil sands to become an energy superpower.
