Global climate change beginning with the Industrial Revolution has led to rising temperatures, warming oceans, shrinking ice sheets, and extreme weather events.
Power generation is a leading cause of air pollution and the single largest source of U.S. global warming emissions. Coal is the worst offender, a dirty energy source that produces less than half our electricity but nearly 80 percent of all power plant carbon emissions,… and (natural gas) is a fossil fuel that generates substantial global warming emissions, and has other health, environmental, and economic risks.

Evidence shows that the atmospheric concentration of carbon dioxide, the largest contributor to industrially-driven warming, has increased by about 90% since 1970, with emissions from fossil fuel combustion and industrial processes contributing about 78% of the increase in total greenhouse gas emissions from 1970 to 2011 (US EPA). This astronomical rise in greenhouse gas emissions has increased the planet’s average surface temperature by about 1.62 degrees Fahrenheit since the late 19th century, with most of the warming occurring in the past 35 years and with the five warmest years on record taking place since 2010 (NASA).
This rise in greenhouse gases and temperature is affecting people all around the world, but especially those most vulnerable such the poor and people living in natural disaster-prone areas. In many parts of the world, climate change has resulted in decreased air quality, agriculture and food scarcity, diminishing water supply, extreme wildfires, and more. If we do not act now to save our home, the impacts of global climate change will only intensify.
