Heat waves, storms, sea levels, glaciers, and wildlife migrations are just a few of the environmental indicators that show measurable signs of climate change, according to a new Environmental Protection Agency (EPA) report.
"Climate Change Indicators in the United States," looks at 24 key indicators that show how climate change impacts the health and environment of the nation’s citizens.
Some of the key findings include:
Greenhouse gas emissions from human activities are increasing. Between 1990 and 2008, there has been about a 14% increase in emissions in the United States.
Average temperatures are rising. Seven of the top 10 warmest years on record for the continental United States have occurred since 1990.
Tropical cyclone intensity has increased in recent decades. Six of the 10 most active hurricane seasons have occurred since the mid-1990s.
Sea levels are rising. From 1993 to 2008, sea level rose twice as fast as the long-term trend.
Glaciers are melting. Loss of glacier volume appears to have accelerated over the last decade.
The frequency of heat waves has risen steadily since the 1960s. The percentage of the U.S. population impacted by heat waves has also increased.
The information included in this report is meant to inform future policy decisions and help evaluate the success of climate change efforts. The data used in this report were collected by several government agencies, academic institutions, and other stakeholder organizations.
