The two words that are heard a lot lately are – climate change. What is the matter?
The average type of weather in a place over the years is called climate. Climate change is the change in that familiar type of weather.
The world is getting warmer and as a result the long-standing familiar behavior of the weather is changing.
What are the consequences of climate change?
People – First of all, what does this change mean for us? Scientists say that this change in climate will change our way of life. Water crisis will be created. Food production will become difficult.
Some areas will become dangerously hot, and many areas will be flooded by rising sea levels. As a result, all those places will become uninhabitable.
Extreme weather conditions – Extreme heat as well as heavy rains and storms will continue to increase abnormally. As a result, life and livelihood will be threatened. Poor countries are less likely to be hit hard by extreme weather.
Atmosphere – As temperatures rise, ice and glaciers in the Arctic are melting faster. As a result, the sea level rises and the low-lying areas of the coast are at risk of drowning.
In addition, in areas such as Siberia, methane gas trapped under the ice will be released into the atmosphere as the ice accumulates in the soil. As a result, another greenhouse gas like methane will increase the magnitude of climate change. This will increase global warming, and increase the risk of forest fires.
Nature- Many animals will move or try to move to new places due to the change of climate in their everlasting habitat.
But this climate change is happening so fast now that many species will become extinct. For example, the melting of ice is endangering the existence of polar bears or white polar bears.
In addition, salmon fish in the Atlantic Ocean will be endangered, as the waters of the rivers in which they lay their eggs and give birth are warming.
Coral reefs or coral reefs in the tropics may disappear as excess carbon dioxide from the atmosphere mixes with seawater, increasing the acidity of the water.
Why this climate change
Some changes occur naturally in the climate due to natural causes. But the level at which the temperature is now rising is mainly responsible for human activities.
The earth’s temperature has risen by 1.2 degrees Celsius since humans began burning factories, vehicles, or burning oil, gas, and coal to keep their homes warm in the winter.
The amount of carbon dioxide, one of the greenhouse gases in the atmosphere, has increased by 50 percent since the nineteenth century. It has increased by 12 percent in the last two decades.
Emissions of greenhouse gases into the atmosphere are also increasing due to deforestation. Plants hold carbon. As a result, when that tree is cut down or burned, the stored carbon is released into the atmosphere.
What will happen in the future?
Scientists believe that keeping the temperature at 1.5 degrees Celsius, which is higher than the temperature of the world before the beginning of the Industrial Revolution, could avoid major dangers. Failure to do so will endanger nature, the environment and human life.
Many scientists fear that there is no way to prevent this terrible consequence and that by the end of this century, global temperatures will rise by three degrees Celsius. Then the effects will vary from place to place in the world:
Rainfall in Britain will increase dramatically and there will be frequent floods.
Many small islands or islands in the Pacific Ocean could disappear as sea levels rise.
Droughts could escalate in many African countries, resulting in food crises.
Extreme heat and drought are expected in Australia.
What are governments doing?
Countries are being told to reduce greenhouse gas emissions to zero by the middle of the current century, by 2050. In other words, the amount of gas that will be emitted should be balanced with measures such as planting additional trees.
If countries can do that, it is hoped that the catastrophic consequences of climate change can be avoided by slowing down the rapid rise in temperature.
What are scientists doing?
There is a lot of research being done on climate change and knowledge about the subject is growing.
Scientists are now able to find the link between climate change and extreme weather conditions, such as rainfall or overheating. As a result, such extreme weather forecasts are expected to be easier in the future.
What can people do?
Reducing reliance on vehicles can increase the use of bicycles or public transport.
He can take measures to keep the house warm or cold.
Meat and dairy foods can reduce.
Air travel can be reduced.
