GLOBAL WARMING
Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. In recent usage, especially in the context of environment policy, it is more generally known as "global warming", which occurs due to increasing levels of greenhouse gases in the atmosphere.
Most of the observed temperature increase has been caused by increasing concentrations of greenhouse gases, which result from human activity such as the burning of fossil fuel and deforestation.
An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts.
Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields.
The atmospheric concentrations of several greenhouse gases are rising as a result of human activities on earth. Carbon Dioxide, one of the most important industrial gases today, is released in the atmosphere largely by burning of fossil fuels like coal, natural gas and oil. Its concentration in the atmosphere is known have increased by 30% over the past centuries. Like CO2 other greenhouse gases such as methane, nitrous oxide have been increasing as well.
Its impacts can be broken down into the following:
Human Health
Human health will be severely at risk if global warming continues to grow. Scientists say that warmer weather will create ideal conditions for the insects and rodents that carry malarial and several other viruses. Heat related illnesses and deaths could increase because of hotter weather and longer heat waves. Rising temperatures could also significantly reduce air quality. This would create ideal conditions for the increase in
