What is Global Warming? To understand global warming a basic understanding of the greenhouse effect is required. Solar radiation absorbed at the Earth’s surface then heat is lost from the earth’s surface as infra-red radiation. The infra-red radiation cannot easily escape from the atmosphere. Some of it is trapped by a number of gases which resulting in the Greenhouse Effect. Global warming is the increase in average temperature of Earth due to the effect of Greenhouse gases. Greenhouse gases include carbon dioxide, methane, nitrous oxide, hydrocarbons. In 1896 Arrhenius was the first to claim that fossil fuel combustion may at some later time result in enhanced Global Warming.The observed rise in temperature over the 20th century was 0.3 to…show more content…
Ecological Changes strongly influence disease patterns. But a warming and change in climate is playing an ever-increasing role in redistribution of infectious diseases. The effect of global warming depends heavily on the ability of humans’ adaptation the direct and indirect impacts of climate change on human health have a considerable toll on life. Although predictions of exact risk posed by climate change is impossible. Vector-Borne Diseases- Climate change will affect disease vectors, which in turn alter the current patterns of vector-borne diseases. Most common vectors, arthropods, are coldblooded, so their internal temperature is greatly affected by the temperature of their environment. The arthropod-borne diseases will depend on both vector and host factors. Climate affects all factors to some extent but will have its most direct effect on the distribution of the vector population. We know malaria as a tropical disease but because of increase in temperature malaria will creep up the mountains and spread to new high altitude areas.Malaria transmission is influenced by climate. Clearly, transmission does not occur in unfavourable climates where mosquitoes cannot survive. Warm, moist climates are most favourable to mosquito propagation and survival.

Cause by exposure to air pollution and allergen. Climate change affect the duration of season, and these changes causing plants to release pollen earlier and longer. In 1990, 183 million people had asthma and then in 2013, 242million people had asthma and 489000 deaths occur in 2013 because of asthma. Cholera:- It’s an infection of the small intestine. Cholera is a bacterial disease caused by a Vibrio cholerae. 3 to 5 million people every year affected by cholera. Both high temperature and heavy rainfall create favorable condition for bacterial growth. In high temperature, dry condition, river level decrease and bacteria accumulate in high concentration and in heavy rainfall flooding can spread bacteria to regions that not previously been infected, bacteria spread fast in flooding condition. What actions can be taken to reduce greenhouse gas emissions (Global Warming):- • Reduce, Reuse, Recycle:- By recycling waste of household waste save 2400 pounds of CO2 annually. • Use less Heat and Air conditioning:- Adding insulation to walls reduce heat cost more than 25%. • Replace bulb:- Replace light bulb with CFL (Compact fluorescent light). • Use less hot water. • Use the OFF switch. • Plant a Tree. • Use renewable energy (hydro, solar, wind
