After the Montreal Protocol treaty banned chlorofluorocarbons, or CFCs, almost 30 years ago, world leaders are once again meeting to discuss a possible treaty amendment that would target hydrofluorocarbons, or HFCs . Many turned to HFCs to use in air conditioners and solvents after CFCs were banned, but HFCs are said to warm the planet even more than carbon dioxide. Diplomats will meet in Vienna this month to consider an amendment which would ” phase down ” HFCs. HFC-134a, which the Institute for Governance and Sustainable Development says is the ” most abundant and fastest growing ” of the HFCs, stays in Earth’s atmosphere for 13.4 years. Granted, that’s not as long as carbon dioxide stays in the atmosphere, but over 100 years, HFC-134a results in ” 1,300 times as much warming as carbon dioxide .” A 2015 study revealed if HFC emissions continue to grow as they are today, by 2050, they could contribute the ” equivalent to nine to 19 percent of carbon dioxide emissions .” Related: Antarctic ozone layer shows “first fingerprints of healing” Scripps Institution of Oceanography climate scientist Veerabhadran Ramanathan told The Washington Post, “The HFCs effect now is very small. The problem with the HFCs is it’s the fastest-growing greenhouse gas . So by banning HFCs, you prevent another disaster downstream. It could be as high as half to one degree [Celsius] by the end of the century.” According to a press release from the United Nations Environment Programme, if parties agree on an amendment to phase down HFCs, the world could avoid the equivalent of around ” 150 gigatonnes of carbon dioxide .” Paul Bledsoe, Former Director of Communications in the White House Climate Change Task Force under President Clinton, told The Washington Post, “The phase out of HFCs will achieve the largest temperature reduction in this century – 0.9 degrees Fahrenheit – of any available policy action.” Via The Washington Post Images via Schezar on Flickr and Coryn Wolk on Flickr

Data from NASA shows that this year’s hole in the ozone layer above Antarctica remains largely unchanged. On September 9, 2014, it measured 24.1m square km, which is roughly the size of North America; only a little smaller than the largest hole ever observed, which occurred in the same spot in 2000, and much the same as it was at its peak in 2010, 2012 and 2013.

Image Credit Our Ontario We Canadians love our maple syrup and have been making it for a long time, but in the end, I would have said that, like the argument over real sugar vs high fructose corn syrup , it’s all just another kind of sugar and no good for you. Then Discovery News tells us to Pour on the Syrup- it’s good for you. ..
