Health and Environmental Effects

Various elements of human society and the environment and sensitive to climate change. Human health, agriculture, natural ecosystems, coastal areas, and heating and cooling requirements is an example of climate-sensitive system. Increasing the average temperature is affecting the environment. Some changes include shrinking glaciers.

Global temperatures continue to increase due to human activities continue to add carbon dioxide, methane, nitrous oxide, and greenhouse.Extent the effects of climate change, whether this effect is proved harmful or beneficial? akan different in each region, over time, and with the ability of different communities and the environment from the system to adapt or cope with change.

The Intergovernmental Panel on Climate Change, concluded that "the impact of climate change will vary" will be increased from time to time as the increase in global temperature. estimate that for global mean temperature increase of less than 1-3 ° C (1.8-5.4 ° F) above the 1990 level, and some sectors will see the impact of benefit while others will experience interference. To further increase the temperature of 2-3 ° C (3.6-5.4 ° F), said is likely that all regions will experience either a decrease in net profit or increase net costs. "Taken as a whole," concluded, "that was published a variety of evidence indicates that the net damage costs of climate change may be important to improve and from time to time.

This section provides information and scientific data on climate change in the past and projections for the future. Specific information about the role of government in the conduct and evaluation of science and the role in this effort can be found on the Climate Change Science Program and Research. Climate change refers to climate change in the action (such as temperature, wind or rain) lasted for long period of time (decades or more). Definition for "climate change and global warming,"

Earth's climate is changing now. Now is the summer. Most of the warming in the decades due to human activity. National Oceanic and Atmospheric Administration's (NOAA) State of the Climate Report and the National aeronautics and Space Administration's (NASA) Surface Temperature Analysis shows the average temperature at the earth's surface increased about 1,2-1,4 º F since 1900. Other aspects of climate change such as the rainfall pattern and storminess.dan must be the solution.
