Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. It is most commonly measured as the average increase in Earth’s global surface temperature. Since the pre-industrial era, human activities are estimated to have increased Earth’s global average temperature by about 1 degree Celsius or 1.8 degrees Fahrenheit per decade.
The advantages of global warming is firstly, the upcoming ice age could possibly prevented. Fewer deaths or injuries would occur to arctic conditions. Longer growing seasons could mean that agricultural production would be expanded partly in some areas, and previously untapped oil and gas reserves might become available.
The disadvantages of global warming include higher sea levels which lead to flooding of low lands, transitions in ocean circulation and the resulting warmer temperatures disrupt the normal weather patterns in the entire world an expansion of frequency in terms of catastrophic storms.
Countries are addressing this global warming to attempt to discover a solution to the worldwide phenomenon. The increase in the amount of carbon dioxide in the atmosphere is considered as the contributing factor for the global phenomenon.
Evidence demonstrates that currently, the world emits about 50 billion of greenhouse gases into the atmosphere yearly.
The goal is to lower emissions net zero, which means attaining an equal balance between the greenhouses put into the atmosphere and the greenhouse gases which are taken out. It would not be easy to cut the emissions out for some underdeveloped countries since it would be costly to try and change the atmosphere, and to use green products such as solar geysers and solar panels. Bill Gates said, ‘‘we need to have price signals to tell the private sector that we want green products’’ which was a statement mentioned from a wealthy individual’s perspective, although he said it is not impossible to change the world’s atmosphere. Another idea which could possibly change the atmosphere is recycling and getting rid of unwanted waste materials which is quite challenging for underdeveloped countries which have busy places such as markets.
It could have been life changing if more than half of the countries (half of 195 countries) could afford to lower emissions to net zero by having a proper budget to purchase green products which do not impair the atmosphere and the earth’s surface, and as a result the diseases of individuals on Earth would also be flattened.
