Global warming has become one of the most serious problems facing humanity in the twenty-first century.
What is global warming?
Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth , which modifies the weather balances and ecosystems for a long time. It is directly linked to increase of greenhouse gases in our atmosphere too.
Since the industrial revolution , the global annual temperature has increased. Between 1880-1980 it rose on average by 0.07 degrees Celsius every 10 years. Since 1981 the rate of increase has more than doubled: for the last 40 years global annual temperature rise by 0.18 degrees of Celsius per decade. Climate scientists around the world have concluded that we must limit global warming to 1.5 Celsius by 2040. Failure to do so could lead to disasters such as droughts , floods , wildfire tropical storms and heat waves. It would be harmful for the humanity and the biosphere.
What causes global warming ?
Humans are the primary contributors to global warming .However , there are some natural causes as well.
The greenhouse effect is a natural phenomenon . The increase of greenhouse gases such as carbon dioxide , methane , nitrous oxide and CFC cause the Earth’s temperature to rise. It has a direct bearing on the disruption on the human activities on Earth.
The massive use of fossil fuel is the main human activity which causes global warming. It produces carbon dioxide as well as nitrous oxide. Deforestation and intensive farming cause global warming too. Trees help to regulate the climate by absorbing carbon dioxide from the atmosphere . When they are cut down, the carbon stored in the trees is released into the atmosphere.
What are the effects of global warming ?
Global warming is having a profound effect on the physical environment, both on humans and the animal kingdom.
Climate change can be identified as an impact on the environment. Hence there are droughts in some areas and heavy rainfall in some areas. This condition is caused in the wind pattern in those areas. In addition, global warming can cause wildfires and heat waves. Glaciers melt and fall into the sea raising sea levels and causing habitat loss.
Global warming is causing an energy crisis around the world . Under this, global warming will accelerate , especially by increasing the efficiency of thermal power plants.
The adverse effects of global warming on human activities can be attributed to the adverse effects on agriculture .In this case, problems such as improper watering , soil infertility , improper planting of crops and reduces yields can lead to crop failure and even a food crisis.
It can be seen that global warming is adversely affecting all the inhabitants of the world.
What are the solutions for global warming ?
Today, various measures are being taken around the world to mitigate global warming.
The creation of an environmentally friendly cover can be described as an important step. Reforestation activates carbon dioxide , which plays a key role in greenhouse gases and it controls global warming.
It also controls global warming by recycling as much as possible , reusing , using energy sparingly , and adopting eco-friendly farming methods.
Humans have a great responsibility to overcome this global warming crisis, one of the main crisis facing mankind today.
