What is global warming tell more?

Answer 1

Basically global warming is the earth being heated up due to greenhouse gases from the burning of fossil fuels, eg. the gas coming out of your car contributes to global warming.

Greenhouse gasses are gases like carbon dioxide, methane, water vapor, sulfates, etc. that hold in heat and prevent it from escaping to space. Some are pollutants, some aren't. Without some greenhouse gasses, Earth would freeze completely solid... all the way to the bottom of the deepest ocean valley!

However, when man started to dig up and burn fossil fuels, like coal, oil and natural gas, in transport and for generating electricity, we started releasing all this extra carbon dioxide that had been stored underground for millions of years. This extra CO2 is disrupting the normal carbon cycle and causing the earth to warm.

Deforestation, cutting down the rain forests, is another cause of global warming.

A:The critical factors impacting global warming and climate change are:

(a) the increase in CO2 levels from emissions from burning fossil fuels;

(b) presence of aerosols or particulate matter in the atmosphere which create a cooling effect;

(c) cement manufacture, and

(d) other factors, such as land development, ozone depletion, animal farming and deforestation also have substantial impact on our climate.

We can stabilize our climate by reducing the greenhouse gas levels in the atmosphere. Annual emissions of greenhouse gases can be balanced by biological and geological sequestration of greenhouse gases. Scientists believe that our biosphere needs reduction of C02 from 390 parts per million (ppm) to under 280 ppm. We believe that these challenges can be achieved using modern technology and practices. Global warming and alternative renewable energy sources are discussed at the link below.

Answer 2

Global warming is the long-term increase in Earth's average surface temperature due to human activities like burning fossil fuels. This leads to the trapping of heat in the atmosphere, resulting in climate change and other detrimental effects like sea-level rise, extreme weather events, and loss of biodiversity. It is a critical environmental issue that requires immediate action to mitigate its impacts.
