Climate Change Conclusions: Is It Real?

Conclusions

The bottom line is the preponderance of reliable data seems to say that the climate has changed since the 1800's, in the direction of a warming earth. Variations are substantial and complex, so new studies are constantly refining the scientific perspective

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

As we find studies that quantify the contributions of each, we will add them!

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.

• 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.
