ECOLOGY AND ENVIRONMENT

Environmental News Network
The mission of this network is to
create environmental awareness
on critical issues
   EPA Curriculum and Resources
Resources for teachers on topics ranging from conservation, air and water pollution to waste and recycling
EPA Student Center
At the student center, youngsters
in the middle and high school grades can explore a wide range
of environmental issues
  The GLOBE Program
The GLOBE (Global Learning and Observations to Benefit the Environment) is a hands-on environment science and education program that unites students, educators, and scientists from around the world in studying 
the global environment.

Earth Island Institute

Earth Island Institute (EII), founded in 1982 by veteran environmentalist David Brower, fosters the efforts of creative individuals by providing organizational support in developing projects for the conservation, preservation, and restoration of the global environment.

Journey to Planet Earth
Hosted and narrated by Matt Damon
World Resources Institute
WRI is an environmental think tank
that goes beyond research to find practical ways to protect the earth and improve people’s lives.

 Climate Change

      Earth's climate is changing. Multiple lines of evidence show changes in our weather, oceans, ecosystems, and more. Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather.The evidence is clear. Rising global temperatures have been accompanied by changes in weather and climate. Many places have seen changes in rainfall, resulting in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. The planet's oceans and glaciers have also experienced some big changes - oceans are warming and becoming more acidic, ice caps are melting, and sea levels are rising.

Natural causes alone cannot explain all of these changes.

       Human activities are contributing to climate change, primarily by releasing billions of tons of carbon dioxide (CO2) and other heat-trapping gases, known as greenhouse gases, into the atmosphere every year. 

     Climate changes will continue into the future. The more greenhouse gases we emit, the larger future climate changes will be.

        Changes in the climate system affect our health, environment, and economy. We can prepare for some of the impacts of climate change to reduce their effects on our well-being.

       The global average temperature has increased by more than 1.5°F since the late 1800s. Some regions of the world have warmed by more than twice this amount. The buildup of greenhouse gases in our atmosphere and the warming of the planet are responsible for other changes, such as:

  • Changing temperature and precipitation patterns Increases in ocean temperatures, sea level, and acidity

  • Melting of glaciers and sea ice 

  • Changes in the frequency, intensity, and duration of extreme weather events

  • Shifts in ecosystem characteristics, like the length of the growing season, timing of flower blooms, and migration of birds

  • Increasing threats to human health

         As these and other changes become more pronounced in the coming decades, they will likely present challenges to our society and our environment.
