Climatic changes

“It’s not that the world hasn’t had more carbon dioxide, it’s not that the world hasn’t been warmer. The problem is the speed at which things are changing. We are inducing a sixth mass extinction event kind of by accident and we don’t want to be the ‘extinctee.’”
– Bill Nye, ‘The Science Guy’
Changes in environment worldwide has had an effect on climate. The amount of ice whether on streams or lakes have vastly reduced throughout the ages. Researchers have anticipated several effects of changes in worldwide environmental changes. Among them are contraction of icy masses, separation of ice in streams and lakes, moving plant and creature ranges and early growth of trees. Other such effects include loss of ocean ice, sped up ocean level ascent and warm ocean waves. Worldwide temperatures are expected to rise soon and are expected to keep rising to a great extent mainly due to human by-products that effect the ozone layer of the atmosphere.
“One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn’t any more available.”
– Stephen Hawking, Physicist & Author



Some of the future effects of climate changes are:
• Changes will continue in the future – the extent of these changes across the following years relies principally upon the measure of heat-trapping gasses discharged globally amd how sensitive the Earth is to these emanations.
• Since it is human-induced, warming is superimposed on a naturally varying climate. Thus the temperature rises across countries will not be level over time.
• Frost-free season will lengthen – This will effect the ecosystem and agriculture. As globally emissions will increase much slowly if the emission of heat-trapping gases are reduced.
• Changes in precipitation patterns – changes in precipitation patterns contribute to sudden heavy precipitation
• More droughts and heat waves – Summer temperatures are expected to continue rising and hereby reduce moisture in the soil. This reduces heat and projected and contributes largely over long time periods.
• Hurricanes – The frequency and duration of hurricanes are increasing with time. Although the contributions of humans towards increasing intensity of hurricanes has been unknown, it recent hurricanes have been quite intense.
• Rise in sea levels – The global sea level has risen by about 8 inches since starting record keeping since 1880. This is due to the melting of ice and polar ice caps. With combined effects, storm surges and high tides cause massive floods in many regions. Rise in sea level will continue and this rate is estimated to rise in future. With such occurences, the arctic ocean will essentially become ice free in summer before the mid century.
Frequent climatic changes are highly damaging to the country’s economy. Several people cannot work properly in these harsh climatic conditions. Businesses are also effected in such conditions. We must take care of Nature in order to prevent such harsh climatic conditions and such frequent climatic changes. The only way to do so is through education of young people in these topics. Schools and colleges should make these topics compulsory in their curriculum. Seminars and practical sessions should be held on the topic of the conservation of Nature.
