Climate Change and Global Warming
What is it and what’s wrong with it?
The “climate” of a geographic location can be defined as the average weather observed in that place. Elements of a climate include temperature, precipitation, humidity, wind, and seasonality. Climatic patterns affect the makeup of natural ecosystems and the lives and activities of humans. Scientists and governments largely agree that the climate is rapidly changing.
Anthropogenic global warming is the gradual warming of the earth over time caused by human activities, namely, the burning of fossil fuels. Pollution from burning carbon releases greenhouse gases like carbon dioxide and methane into earth’s atmosphere, which traps heat from the sun and warms the earth. Global warming leads to climate change.
According to Dr. James Hansen (formerly of NASA) and 97% of climate scientists worldwide, manmade production of CO2 is the leading cause of global warming and climate change. Global warming threatens our human future on this earth, and the future of all living beings.
One of the most outspoken leaders of the movement to halt global warming is Bill McKibben. According to McKibben's organization 350.org, “[for all of human history] until about 300 years ago, our atmosphere contained 275 parts per million (ppm) of carbon dioxide. About 300 years ago, humans began to burn coal and oil to produce energy and goods. By now—the planet has reached 391 parts per million—and this number is rising by about 2 ppm every year.”
What’s been done?
McKibben warns that the dangers that face us as a result of global warming are immense; unless we make drastic changes to reduce our carbon dioxide (CO2) emissions, life on earth as we know it will disappear in the very near future. Natural disasters will increase, land mass will be reduced, islands and countries will vanish. We will see famine, clean water depletion, excessive heat and intense weather patterns. As we have seen with Hurricanes Katrina (2005) and Sandy (2012), and the earthquake and tsunami in Fukushima (2011), natural disasters increase with an extreme change in our climate. According to McKibben, we've passed the tipping point, but we don't want to make things worse by sitting on our hands. Despite our clear climatic catastrophe, the U.S. government refuses to sign important commitments to reduce C02 emissions--such as the KYOTO agreement.
Actions to radically reduce carbon emissions must take place immediately or the consequences will be dire in the near future and for years to come. In recognition of this fact, hundreds of thousands of people took to the streets in New York City on September 21, 2014, to take part in the People's Climate March. Around the world, hundreds of similar climate-action events took place that same day to bring attention to the issues of climate change.
Other key leaders in this movement: Al Gore. Gore's movie An Inconvient Truth, brought great worldwide attention to the crises of global warming. Dr. Heidi Cullen of Climate Central educates on this issue. Elizabeth Kolbert, author of “Field Notes from a Catastrophe” (2006) writes about global warming for The New Yorker. Naomi Klein, author of The Shock Doctrine: The Rise of Disaster Capitalism is an outspoken opponent of the Keystone Pipeline and a climate change activist.
Tim DeChristopher, an important global warming activist, recently went to jail for three years for his protest of climate change. Read about his powerful story and the large community of activists who support him here: http://www.peacefuluprising.org/
What you can do?
Consume less! Conserve your energy!
-Walk, bike, carpool, or use public transportation
-Live close to your job or school to reduce or eliminate your commute
-Turn down your heat & ensure your home/windows/doors are well insulated and sealed
-Unplug what you are not using
-Use LED light bulbs
-Don't waste electricity or leave your car running
-Don't eat meat--believe it or not, meat production is one of the largest sources of greenhouse gas emissions
-Reduce, reuse, recycle
-Encourage businesses to burn less carbon!
