Millions of kilometers away from Earth, launching trillions of plastic lenses 60 centimeters in diameter, each weighing 1 gram, could form a cloud of 260,000 square kilometers, reducing the amount of sunlight hitting Earth by about 2 percent. Professor Angell believes that the project, which requires the production of 20 million tons of lenses and fired with a giant cannon, can be completed within 25 years and cost several trillion dollars. The problem is that manufacturing and emitting lenses also requires a lot of energy, and how to solve this contradiction has become a new problem.

Global warming is the long-term heating of Earth’s surface 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. This term is not interchangeable with the term "climate change."

Since the pre-industrial period, human activities are estimated to have increased Earth’s global average temperature by about 1 degree Celsius (1.8 degrees Fahrenheit), a number that is currently increasing by more than 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. The current warming trend is unequivocally the result of human activity since the 1950s and is proceeding at an unprecedented rate over millennia.

How climate affects us

global warming

The continued development of global warming threatens human beings not only with the impact of high temperature, but also with extreme rainfall, melting glaciers - rising sea levels and other issues.

Reason

1. Population surge factor The surge in population in recent years is one of the main factors leading to global warming. At the same time, it also seriously threatens the balance between the natural ecological environment. With such a large population, the amount of carbon dioxide emitted by itself every year will be an astonishing number. As a result, the content of carbon dioxide in the atmosphere will continue to increase, and the carbon dioxide "greenhouse effect" formed in this way will directly affect the earth's surface climate. Variety.

2. Causes of atmospheric pollution. The increasingly serious environmental pollution has become a major global problem, and it is also one of the main factors leading to global warming. In the 21st century, research on global climate change has clearly pointed out that the temperature of the earth's surface has begun to rise since the end of the last century.

3. Greenhouse gases, while most greenhouse gases are produced naturally, human activities also contribute to greenhouse gas emissions and their concentrations in the atmosphere. This increase in concentration, in turn, can adversely affect the climate. Its effects include frequent extreme weather events, including floods, droughts, wildfires and hurricanes. This affects millions of people and causes trillions of dollars in economic damage.

Impact

Rising sea levels, rising sea levels also means more disasters. In recent years, the global temperature has gradually increased, and the temperature may increase by 1.5° between 2030 and 2052. The impact of global warming will become more and more harmful to us and even the entire planet. As the world warms, some shocks such as severe heatwaves, fires, droughts and floods become more likely.

measures to mitigate global warming

1. Develop environmentally friendly technology and replace it with renewable energy such as solar, wind and hydroelectric power.

2. Build a sound railway system and encourage citizens to use public transport to reduce vehicle emissions

3. Educate people about the scourge of global warming, and realize that they should take responsibility for it and reduce the release of greenhouse gases.
