Turn down the heat: Global Warming

Almost everyday the news contains reports about global warming. We hear about the millions of cars on the road, releasing carbon dioxide and smog causing pollutants. How and when do we end our relliance on coal-fired electricity generation, the single largest source of greenhouse gases. Deforestation is happening here there and everywhere, depleting the planet's natural ability to regulate the climate.
Human activity has a huuuuge impact on the world's climate.
Pollutants that trap heat in the atmosphere are causing changes to global climate. The average global temperature has rose by 0.7 degrees celsius since the Industrial Revolution. They say its something like the fatest rate of warming the world has seen in the past like... 10, 000 years!
It's been agreed by the science community that if that global temperature rises by 2.0 degrees celsius above pre-industrial levels, that there will be irreversible damage done to our planet. Even though there's some action being taken to reduce greenhouse gas emissions, we're well on our way to that mark. They say by 2050. And will we will continue to exceed this dangerous threshold unless dramatic actions are taken.
Some impacts that have been either predicted or are already upon us are such things as: melting ice caps, rising sea levels, disrupted occean currents, drier droughts, more frequent floods and hurricanes, wider spread of tropical diseases, and food shortages. As it increases, its effects are being felt from the very tip of the highest mountains to deep in the oceans, and from the Equator to the poles. People are at risk. Nature and species are at risk.
People. The heatwave in August of 2003 in Europe was the hottest in 500 years. It killed close to 40, 000 people. Weather invents due to global warming, are more intense and last longer, being more frequent aswell. Not to mention that millions of people around the world live only one metre above sea level. If the heat of global warming melts the Arctic and Antartica ice sheets.... sea levels could rise to nearly 7 metres. Some some islands face complete obliteration. Not to mention that in burning coil and oil, together with high temperatures, more urban smog is becoming more intense and resulting in asthma and other horrible respiratory problems.
Nature. It's been revealed that climate change could potentially result in extinction of more than a million! terrestial species within the next 50 years. Polar bears for example, could become extinct within the next 100 years, due to their natural habitat virtually disappearing. Coral reefs are being damaged by unususally warm ocean temperatures and a decline in them results in fish, sponges, turtles, etc. lacking habitats, and eliminating the livlihood of billions of people. 1/3 of our forests are at risk, aswell as their inhabitants that depend on forests for their survival.
WWF-Canada is working with many stakeholders including government, corporations and individuals to decrease greenhouse gas emissions and ensure the effects of climate change are as minimal as possible.
There are even simple tips any person could easily follow to save energy. Simple changed can make a big difference. Recycle - cardboard, plastic, glass, cardboard and newspapers, 100% of it! Adjust your thermostat - 1 degree celsius down in the winter, and 1 up in the summer. You'll lower your utility bills and reduce gas emissions. If you're not using it, turn it off - Tvs, Dvds, stereos, computers, and lights. Simple, right? Even in standby, atleast 10 to 60 percent of energy is used. If I left my computer on for the whole night tonight, it would produce enough energy to print over 5, 000 copies. Wash economically. Dishwasher not full, don't use it until it is. Same with the laundry. Save even more by trying not to use hot water when washing clothes. Fluorescent bulbs are an idea aswell! Plug up the leaks, that's another. Be garden smart, don't use synthetic fertilizers. Set your hot water stat at 50 degrees C . Don't leave your fridge open for longer than necessary, let food coold down before putting it in the fridge. Where possible, dont stand an oven and fridge/freezer next to each other. See, all these listed above are quite simple actions to take. Bear them in mind, they're all steps forward to fighting this together!
