Climate change means a long-term change in the temperature and weather around the atmosphere. These changes may be natural or man-made. Since the 1700s, human activities have contributed a lot to climate changes more than anything. For example, burning fossil fuels emits greenhouse gas and raises the temperature, depletion of natural resources, and air pollution from industries, buildings, and transport. Here’s the Climate Change Report 2021 to give us a better analysis of the present climate change situation.
Climate change can affect everyone globally with their health, food, housing, and work. This is the world where everything is interconnected, and if climate change begins with an increase in temperature, it can be far more catastrophic than our imaginations.
Greenhouse gas emission causes climate changes in every part of the world, affecting everyone. According to the reports in the last decade (2010-2020), earth temperature has increased by about 1.1°C.
Suppose emission and climate changes continue to change. In that case, people must keep in mind that the consequences of climate changes must be destructive, like intensive droughts, fires, flooding storms, declining biodiversity, and rising sea level.
Climate change is a global crisis that is totally beyond borders. So what will happen to climate changes in 2021?
-On 25 January, Cryosphere reported that the global sea level rose by 3.1mm due to melting glaciers.
-On 9 February, environmental research concluded that the burning of fossil fuels causes 8.7 million premature deaths by airborne particles.
-For the first time, Mauna Loa Observatory says that the peak CO2 level reached 50% higher than the pre-industrial level.
-On 26 February, The United Nations synthesis report under The Paris agreement said to ” estimated reduction in the green grass house emissions to strengthen their commitment.”
-On 28 April, Nature concluded that melting glaciers rose 21% of sea level from 2000 – 2019.
-On 31 May, a nature climate change report says there has been a 37% heat-related death in the last two decades due to climate change.
-On 21 June, according to The World Meteorological Organization, 2021 will face the worst impacts of climate changes with droughts and intense floods.
On 28 July, as a warning of a climate emergency, we have already crossed the tipping point for the critical point of the earth.
-On 1 September, Nature published that fire in the Amazon forest has reduced biodiversity by about 77% to 85%.
-On 6 September, over 200 journals published a global increase in temperature by 1.5°C.
-On 16 February, Bill Gates published the book How to avoid the climate disaster.
-On 17 February, Ford sales began to decrease the use of petrol and diesel and will offer only batteries and electric cars by 2030.
– On 25 March, the supreme court of Canada passed the greenhouse gas pollution pricing act 2018.
In 2018, the UN reported that all would be acceptable if we curb the human activity affecting the climate; temperatures need to be lowered by 1.5°C to avoid the worst effects of climate change. Use renewable resources in the place of conventional resources, cut fossil fuels, and replace them with biofuels.
However, if emissions continue at the current rate, global temperatures will rise by 4.4°C by the end of the century.
The scientist observed changes in the earth’s climate and concluded the report, but if human activities continue unchecked, the effects could be disastrous in the coming years. The return rate of human activities can be very high and may be a risk for human life.
