Global warming is defined as an increase in the average temperature of the Earth’s atmosphere, especially a sustained increase significant enough to cause changes in the global climate. The term global warming is synonymous with an enhanced greenhouse effect, implying an increase in the amount of greenhouse gases in the earth’s atmosphere, leading to entrapment of more and more solar radiations, and thus increasing the overall temperature of the earth.
New greenhouse gas with highest global warming impact discovered
A new discovery by scientists has revealed a new greenhouse gas that appears to have the highest global-warming impact. Perfluorotributylamine (PFTBA) – discovered by Toronto’s Department of Chemistry research team concluded that the compound is most effective in potential to harm the climate, in a30
Effects of Global Warming
Global Warming is the increase in temperature on the earth’s surface due to the greenhouse gas emission. There are innumerable causes of this catastrophe.
- 1. Deforestation, Greenhouse gas emission, overuse of fuels, etc. The effects of Global warming are deadlier than our imagination.
- 2. Global Warming is the root cause of many diseases. Some of these diseases are incurable. The effects of Global Warming prove to be destruction to the human race.
- 3. The most hazardous effect of Global Warming is increase in world temperature. The weather in summer season is extreme arid.
- 4. Another major effect of this global crisis is rise in sea-level. This could result in flooding in low-lying areas.
- 5. Many countries experience rainfall at unexpected times.
- 6. Natural calamities such as hurricanes, storms, floods, etc. are now a routine to people residing in disaster prone areas. The aquatic life is endangered due to change in the temperature of oceanic waters.
- 7. Chemical industries which release dangerous gases such as CFC, CO2, CO mix up with the atmosphere.
These all above, causes the depletion of ozone layer. Greenhouse gases mix up with the rain clouds which give rise to acidic rains. Today, innumerable trees are lying lifeless due to acidic rain. Fire-Brigade personnel control the flumes of fire. Trees perform the same task by lowering the risk of Global Warming. Today hardly 30% of the earth’s surface is covered by trees which is an alarm to the residents of the earth.
How to control
We can’t stop travelling by vehicles but certainly we can opt for CNG as an alternative to petrol and diesel. If we travel by public transport, we can save litres of petrol and also the pollution occurring due to emission of carbon-monoxide.
Tree plantation is the key to save our nature. Trees absorb the atmospheric CO2 and convert it into oxygen which is not a greenhouse gas. If every individual plants a tree per year, the population of the trees on the earth would certainly rise up. Burning of fossil fuel leads to greenhouse gas emission. Another solution of this difficult ‘Equation’ is by using less energy and recycling more products. The solution has numerous benefits.
Lastly, I would conclude by saying that if we put efforts to stop the Global Warming, the following generations wouldn’t be familiar with this term only! We are a part of nature and not apart from it. We must take pledge to ourselves to save our dearest Mother Nature who has always cared us like her progeny. If we try to destroy nature, we’ll have to suffer double the destruction. Nature’s debt is un-repayable.
