Climate Change Conclusions: Is It Real?

Conclusions

If you were looking for just the bottom line, you'll have to wait. We're still gathering the references, studies and data from all sides in the debate. As we find one study or report from one side or the other, which appears to be conclusive, we then find evidence refuting that study. So until we complete that process, we'll only say that the preponderance of reliable data seems to say that the climate has changed since the 1800's, in the direction of a warming earth.

Whether this is directly or primarily caused by mankind is yet to be proven.

Conclusions: Climate Change is Caused by...Man? Nature? Some of each?

We're not there yet. Stay tuned.

Response to Climate Change Should be...

Regardless of whether climate change is caused by mankind, the localized effects of pollution, waste and inefficiency, on people, society and nature are so detrimental that it ought to be obvious that we should not pollute and should not waste. We should move toward cleaner sources of energy. The question about how fast to move in that direction, how to pay for it, how to incent; these are not scientific questions, but rather belong in the realm of society and human costs.

More about Climate Change

Climate Change Research

    EPA research improves knowledge of the impacts of climate change on human health and the environment. The scientific information and tools can be used by communities to effectively and sustainably manage the impacts from a changing world.

  • Climate Change Research
  • EPA conducts research to understand the environmental and health impacts of climate change and to provide sustainable solutions for adapting to and reducing the impact from a changing climate.

  • Agriculture and Climate
  • Climate change affects agricultural producers because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause crop planting dates to shift. Droughts and floods due to climate change may hinder farming practices.

  • Air Quality and Climate Change Research
  • EPA is conducting research to understand the relationships between climate change and air quality by advancing the understanding of temperature changs on ozone and particulate matter concentrations and changes in pollen and allergic disease patterns.

  • King Tides and Climate Change
  • The highest predicted high tide of the year at a coastal location can bring unusually high water levels and can cause flooding. Learn about these tides including what they are, when they occur, and what they can mean for the future.

  • Climate Change in Coastal Communities
  • Estuaries and coastal areas are vulnerable to many impacts of climate change such as sea level rise and ocean acidification. Learn about these impacts and how resource managers can prepare for them.

  • Climate Change and Children's Health
  • In 2007, sixteen percent of children lived in counties exceeding the annual fine particulate matter standard. Exposure to higher levels of ambient particulate matter and ozone may increase school absences and hospital admissions due to respiratory illness.
