How an enhanced greenhouse effect can harm the planet?
The enhanced greenhouse effect, sometimes referred to as climate change or global warming, is the impact on the climate from the additional heat retained due to the increased amounts of carbon dioxide and other greenhouse gases that humans have released into the earths atmosphere since the industrial revolution.
Why is the enhanced greenhouse effect a problem?
The greenhouse effect traps some of the energy from the Sun, which keeps our planet at a suitable temperature for life. The problem is that our increased release of greenhouse gases is causing an increase in the greenhouse effect called the enhanced greenhouse effect. This is leading to global warming .
How is the enhanced greenhouse effect different from the greenhouse effect?
The lower atmosphere is likely to warm, changing weather and climate. Thus, the enhanced greenhouse effect is additional to the natural greenhouse effect and is due to human activity changing the make-up of the atmosphere. (The enhanced greenhouse effect is often referred to as global warming.)
Why is the natural greenhouse effect necessary to life on Earth?
The greenhouse effect is a natural process that warms the Earth’s surface. The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.
What is bad for the atmosphere?
An air pollutant is a substance in the air that can cause harm to humans and the environment. Through the burning of fuel, motor vehicles, cars and trucks emit a range of health damaging pollutants, such as particulate matter, nitrogen oxides, sulphur dioxide, carbon monoxides and Volatile Organic Compounds (VOCs).
How are we destroying the atmosphere?
Human activities cause ozone depletion and global warming Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below).
Why global warming is a serious threat?
It also refers to sea level rise caused by the expansion of warmer seas and melting ice sheets and glaciers. Global warming causes climate change, which poses a serious threat to life on earth in the forms of widespread flooding and extreme weather.
Why do we need to stop global warming?
“Climate change exerts a de-stabilizing influence on an already-unstable world,” says Peter deMenocal, a climate scientist with Columbia University. “It adds a fundamental insecurity to people’s lives and livelihoods, from small island nations to the most developed nations in the world.
What are the negative effects of global warming?
Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few. Some of Australia’s great natural icons, such as the Great Barrier Reef, are already threatened.
Will humans evolve again?
The short answer is that humans are evolving right now and will continue to do so even if we don’t notice it.
What is the life of Earth?
3.5 billion years
