Global Warming

                                      

What is Global Warming

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.

                        What are the reasons behind Global Warming 

Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.

                                     1. Burning fossil fuels

When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.

Electricity generation is the main cause of carbon pollution as 73% of our electricity comes from burning coal and 13% from burning gas

                               2. Deforestation & Tree-Clearing

Plants and trees play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it.

Up to one-fifth of global greenhouse,  gas pollution comes from deforestation and forest degradation.

                             3. Agriculture & Farming

Animals, livestock like sheep and cattle, produce methane, a greenhouse gas. When livestock graze at a large scale, the amount of methane produced is a big contributor to global warming.

                                                                                                                                                             What can be the solutions for these all three reasons of Global Warming   

                           Solutions for Burning Fossils. 

•Reducing the amount of electricity generated from coal and gas

•Increasing the amount of electricity from clean, renewable energy sources like solar and wind 

                      Solutions for Deforestation and Tree-Clearing

•Prevent deforestation and tree-clearing

•Plant more trees through reforestation and afforestation

•Shop sustainably

•Call on our leaders to introduce stronger laws to stop excessive tree-clearing

                  Solutions for Agriculture and Farming

•USING ... different stock feeds can help  reduce farming's contribution to climate change

•WWF is working with leading beef producers through ‘Project Pioneer’ to develop, trial and validate improved livestock and pasture management that can deliver significant economic, social and environmental gains.

                            What’s the Greenhouse Effect

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).

                  

                         Is Greenhouse effect good or bad 

The greenhouse effect is a good thing. It warms the planet to its comfortable average of 59 degrees Fahrenheit (15 degrees Celsius) and keeps life on earth, well, livable. Without it the world would be a frozen, uninhabitable place, more like Mars. The problem is, mankind’s voracious burning of fossil fuels for energy is artificially amping up the natural greenhouse effect.

                What is happening on this planet earth due to Global Warming 

This year is set to be the second hottest year in history and each of the disasters in the report has a link with climate change

                  Natural Disasters and Climate Change that happened recently

These included the floods that ravaged north India, typhoon Lekima in China, Hurricane Dorian in the United States, floods in China, floods in the Midwest and southern United States, typhoon Hagibis in Japan and the California wildfires, the costliest tragedy at $25 billion.

These include Cyclone Idai in Mozambique, typhoon Hagibis in Japan, a deadly, record-breaking heatwave across much of Europe, wildfires in California and eastern Australia and floods in Venice.

        What will happen, if Global Warming keeps increasing               

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.

Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. If all these man- made  disasters continue to happen, more and more glaciers will melt and half of the earth will submerge under seas and oceans

                               Ozone depletion and ozone hole 

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these strastropheric events.

                           

                     Steps needed to avoid Global Warming

•Change a light. Replacing one regular light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year.

•Drive less. ...

•Recycle more. ...

•Check your tyres. ..

•Use less hot water. ...

•Avoid products with a lot of packaging. ...

•Adjust your thermostat. ...

•Plant a tree.

It’s the duty of each and every human being to follow these steps,

and save our planet earth from getting destroyed
