Deforestation is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity. For example, in the Amazon, around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. Deforestation in this region is chiefly rampant near more populated areas, roads and rivers, but even remote areas have been encroached upon when valuable mahogany, gold and oil are discovered.
Some 46-58 thousand square miles of forest are lost each year–equivalent to 36 football fields every minute… read more.
Current and Future Impact In the United States alone, a large majority of the population recognize that the worsening effects of climate dysfunctions on water, food, land, and wildlife are evident. They also seem to agree that climate change is not a fatality. read more.
Early in the morning on August 29, 2005, Hurricane Katrina struck the Gulf Coast of the United States. When the storm made landfall, it had a Category 3 rating on the Saffir-Simpson Hurricane Scale–it brought sustained winds of 100–140 miles per hour–and stretched some 400 miles across. The storm itself did a great deal of damage, but its aftermath was even more catastrophic. Levee breaches led to massive flooding, and many people charged that the federal government was slow to meet the needs of the people most affected by the storm. Hundreds of thousands of people in Louisiana, Mississippi and Alabama were displaced from their homes, and experts estimate that Katrina caused more than $100 billion in damage.
Around Lake Chad in West-Central Africa for instance, unsustainable projects have continued to divert water from the bassin. Lake Chad has been a source of freshwater for irrigation projects in each of these countries. Maps drawn from a series of satellite images show a dramatic decrease in the size of the lake over the past 30 years. Since 1963, the lake has shrunk to nearly a twentieth of its original size, due both to climatic changes and to high demands for agricultural water. Since 1963, the surface area of Lake Chad has decreased from approximately 25,000 km2 to 1,350 km2 (Scientific American, 2001).
In Costa Rica 175 mm of rain fell in 24 hours between Monday July 6 and Tuesday July 7, 2015 heavy rainfall and flooding on. The World Meteorological Organization (WMO) http://www.wmo.int/ reported that Puerto Limon saw 174.9 mm of rain fall in 24 hours during that period. Costa Rica’s National Meteorological Institute have warned that the heavy rainfall will continue.
Rising temperatures will speed up the melting of glaciers for years to come. According to NASA, the polar ice cap is now melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s.

US Clean Air Act – the comprehensive federal law that regulates air emissions from stationary and mobile sources… read more.
One of the goals of the Act was to set and achieve National Ambient Air Quality Standards (NAAQS) in every state by 1975 in order to address the public health and welfare risks posed by certain widespread air pollutants. The setting of these pollutant standards was coupled with directing the states to develop State Implementation Plans (SIPs) applicable to appropriate industrial sources in the state, in order to achieve these standards. The Act was amended in 1977 and 1990 primarily to set new goals (dates) for achieving attainment of NAAQS since many areas of the country had failed to meet the benchmarks and the deadlines.
