Climate change includes both global warming caused by human-produced greenhouse gases and the resulting large-scale shifts in weather patterns. Even though there have been periods of climatic change throughout history, since the mid-20th century, humans have had an unprecedented impact on the Earth's climate, causing huge problems on a global scale. And one Facebook page perfectly illustrates how many of us feel about it.
It's called Rare and Endangered Memes for Edgy Environmentalists and it gives people exactly what its name suggests.
"This page doesn't adhere to a specific branch of environmentalism or a specific political ideology, although we have hard left leanings," the admins wrote in its 'About' section. "Our goal is simply to save the planet with the power of edgy green meme comics."
Scientists believe that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.
The IPCC also predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.
"Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time."
Of course, we have to do more than create and share memes. But it's a start.
