Climate Change- Biggest problem of 21st century

Did you notice the days are being warmer and warmer than they used to be? Have you ever realized how come the spring so earlier and aren't the winters short enough? This is all due to the change in climate. Simply understanding, climate change is a change in statistical distribution of weather pattern not only regionally but also globally. It is one of the most serious issues of 21st century which has already started showing observable effects in surrounding. Many of the prediction that scientists made regarding climate change has not gone wrong. And if this issue is not fixed on time, then the future generation is likely to have hazardous effect.

          Climate change occurs due to different reasons. Volcanic eruptions, variations in solar radiation received by Earth, plate tectonics, variation in reflectivity of atmosphere, oceans  etc are some of the causes. Apart from natural and biotic processes, artificial activities by man are another chief cause.  Human beings, being the supreme creature of this planet are primarily responsible for this rising problem.  The main culprit is human induced emission of greenhouse gases. These gases lead to global warming and global warming leads to rise in temperature of our planet that ultimately shows the effects of climate change. 

Increased greenhouse effect and global warming cause polar ice caps and glaciers to melt as well as stimulate the thermal expansion of ocean which results in rise of seal level. Hurricanes, heat waves, floods, drought and tornadoes everywhere are projected to become more intense. The length of frost free season and corresponding growing season are shifting. The number of freezing day is declining. These changes affect the timing and makeup of natural life cycle events.

The change in climate has badly affected forest areas drying out soil moisture which induces forest fire. Firstly, climate change forbids proper growth of trees; secondly, forest fire destroys the available trees. The two way destruction adds further negative impacts on surrounding. Agricultural practices are also not free of the hazards. The net yield of agricultural crops gets decreased and the quality of seeds too gets degraded. Hence, the global price goes down which turn out to be a great loss to farmers. These all signs show that there is going to be a massive challenge for us to maintain food security.

  Human activities such as use of improper drainage, disposal of carcasses, wastage from commercial, household and industrial activities into water bodies have already caused water pollution. In addition to these actions, when climate change combines makes the situation more worsen. Natural calamities such as floods and droughts in their extreme intensity will occur taking the lives of many living beings, polluting environment and causing destruction of infrastructures. Flood contaminates the fresh water resources and there turn out to be the risk of diarrheal diseases. It is expected that two hundred fifty thousand additional deaths occurs per year due to different diseases like malaria, malnutrition, cholera, diarrhea etc. Extremely high temperature produces heat wave of summer and has effect on heart and lungs. Cardiovascular diseases, asthma and respiratory diseases, especially among elderly people are recorded in Europe. Not only human beings but also animals and birds will be losing their habitat. Endangered, threatened, vulnerable and rare species are at risk.  Their existence might extinct for forever, if present situation continues.

 Politically and economically, many countries are trying to solve the problem worldwide through COP but there are still other measures, which we can apply in local level. Highly industrialized countries are more culprits of climate change but the impacts fall upon all the countries that are not developed industrially. That's why it has become a necessity of all people, across the world to search a solution with respect to climate change. We cannot undo the impacts that have been already caused but we definitely can reduce the approaching effects. Alternative sources of energy should be searched. Solar, wind, geothermal and bio energy  must be preferred to non- renewable ones. Consumption of fossil fuels must be reduced. New measures of low carbon and zero carbon technology should be developed.Since, plants absorb carbon dioxide and liberate oxygen for us, afforestation programs must be launched from community to national level. 1 plant (biogas) saves 5 tons fuel wood/year, 1000 installed plants saves 5000 tons of fuel wood per/year.

 Our homes also contribute in emission of gases. Let's try to reduce them. We must not forget to turn off the appliances when not in application, use energy efficient recommended models, insulate the home and try to make lifestyle greener to reduce greenhouse gases. One of the most important steps we can do is raising public awareness. We can teach others about the risks that are being observed globally. It is not sufficient that only few researchers, limited job holders dealing with the issues, intellectual persons and media persons know about climate change. Common people also know about this situation so that they also would join to reduce global warming. Who knows, our small step will inspire other to join with us. So, let's think globally and act locally to reduce severe climate change and save our Earth.
