Over the last one to two centuries, the phenomena of rising average air temperatures near the Earth’s surface. Climate scientists have been collecting extensive data on numerous weather events (such as temperatures, precipitation, and storms) and associated effects on climate (such as ocean currents and the chemical makeup of the atmosphere) since the mid-twentieth century.

These findings show that Earth’s climate has changed on virtually every possible period from the beginning of geologic time and that human actions have been profoundly woven into the fabric of climate change since at least the beginning of the Industrial Revolution.

Causes of Global Warming

Global warming is a type of climate change that refers to the rise in global temperatures over time. Increased levels of greenhouse gases in the atmosphere, primarily from human activities such as burning fossil fuels and farming, are to blame.

1. The use of fossil fuels

We emit CO2 pollution into the environment when we burn fossil fuels like coal and gas to generate energy or power our automobiles.

  • In comparison to the rest of the world, Australians are major CO2 polluters. Our CO2 emission per person is roughly double that of other industrialized countries and more than four times that of the rest of the globe.
  • In Australia, power generation is the leading source of carbon pollution, with coal accounting for 73% of our electricity and gas accounting for 13%. The remaining 14 percent comes from carbon-free renewable energy sources, including hydro, solar, and wind.

Solutions:

  • Reducing the proportion of coal and gas-fired power.
  • Increasing the quantity of power generated from clean, renewable sources such as solar and wind.
  • Join the call for more climate action and encourage key Australian leaders to put Australia back on track to fulfill the Paris Agreement’s goals.

2. Deforestation and Tree Removal

Plants and trees play an essential role in climate regulation because they take carbon dioxide from the air and release oxygen back into it.

  • Forests and bushland function as carbon sinks, helping to keep global warming below 1.5 degrees Celsius.
  • On the other hand, humans clear large swaths of land all over the world for farming, urban and infrastructural development, and the sale of tree products like wood and palm oil.
  • When vegetation is cut down or burned, the stored carbon is released as CO2, contributing to global warming.
  • Deforestation and forest degradation are responsible for up to one-fifth of worldwide greenhouse gas emissions.

Solutions:

Stop tree-clearing and deforestation.

  • More trees should be planted through reforestation and afforestation.
  • Shop with a conscience.
  • Demand that our politicians pass stricter legislation to prevent excessive tree-clearing.

Agriculture and farming are three of the most important industries in the world.

Methane, a greenhouse gas, is produced by animals such as sheep and cattle. The quantity of methane generated by cattle grazing on a vast scale, such as in Australia, contributes to global warming.

  • Some of the ones used by farmers also emit nitrous oxide, which is a greenhouse gas.
  • Agriculture accounts for 16% of Australia’s total greenhouse gas emissions.

Solutions:

  • Using a variety of animal feeds can assist decrease agriculture’s impact on climate change.
  • Through ‘Project Pioneer,’ WWF is collaborating with leading beef producers to design, test, and evaluate enhanced cattle and pasture management that can result in major economic, social, and environmental benefits.

This is why fighting climate change is so urgent…..

How Can You Help to Prevent Global Warming?

Even though President Trump just declared the United States’ departure from the Paris Agreement, countries worldwide are raising their game in the battle against climate change. Despite this rash decision, American mayors, state leaders, county officials, governors, large corporations, and millions of individuals have sworn that they are “still in” on the accord, supporting the objective of keeping future warming far below 2 degrees Celsius.

Even better, a new project spearheaded by former New York City mayor Michael Bloomberg bolsters the movement’s urban component. He’s invited mayors from the country’s top 100 cities to discuss their proposals for making their towns’ buildings and transportation systems cleaner and more efficient. Bloomberg Philanthropies and partners will award a total of $70 million in technical assistance financing to the 20 organizations that show the most promise in reducing the hazardous carbon pollution that is causing climate change.

The objective is straightforward. The biggest enemy of the climate is carbon dioxide. When oil, coal, and other fossil fuels are burnt for energy—the energy that powers our houses, vehicles, and smartphones—it releases carbon dioxide. We can reduce our personal impact on climate change while simultaneously saving money by using less of it. Here are a dozen simple, practical ways that every one of us may help:

1. Take a stand!

What is the single most important thing you can do to help combat global climate change?

  • “Talk to your friends and family about it, and make sure your representatives are making the right decisions,” You may show that you care about global warming by sharing your concerns on social media or, better yet, directly to your elected leaders.
  • Encourage Congress to pass new legislation limiting carbon emissions and requiring polluters to pay for their pollution.
  • “Elected politicians do tough things because their constituents force them to,” explains. Here’s where you can help save public lands, stop offshore drilling, and more.

2. Use sustainable energy to power your home.

Choose a utility that gets at least half of its energy from wind or solar and has been certified by Green-e Energy, a non-profit that evaluates renewable energy choices. If that isn’t an option, check your power bill; many companies now include information on additional methods to support renewable energy on their monthly statements and websites.

3. Weatherize, weatherize, and weatherize some more.

Building heating and cooling are among the most energy-intensive activities,

Heating and cooling account for about half of all household energy consumption. Sealing draughts and maintaining proper insulation can help you make your room more energy efficient. Many energy-saving home renovations are also eligible for federal tax incentives.

4. Purchase energy-saving appliances.

Since 1987, efficiency requirements for hundreds of appliances and goods have prevented 2.3 billion tonnes of carbon dioxide from entering the atmosphere. That’s almost the same amount of carbon pollution produced year by approximately 440 million automobiles. “The most cost-effective method to cut emissions is to improve energy efficiency.” Look for the Energy Star logo on refrigerators, washing machines, and other appliances while purchasing. It will inform you as to which are the most effective.

5. Cut down on water waste.

Conserving water also helps to minimize carbon emissions. That’s because pumping, heating, and treating your water uses a lot of energy. So take shorter showers, turn off the faucet while brushing your teeth, and replace your fixtures and appliances with WaterSense-labelled models. According to the EPA, retrofitting one out of every 100 American houses with water-efficient fixtures would save roughly 100 million kilowatt-hours of energy each year, preventing 80,000 tonnes of global warming pollutants.

6. Consume the food you purchase—and eat less meat.

Approximately 10% of the energy used in the United States is used to cultivate, prepare, package, and distribute food, with about 40% of it ending up in landfills. “If you waste less food, you’re probably consuming less energy. Eating meat-free meals may also make a huge difference because animal products are among the most resource-intensive to manufacture.

7. Upgrade your light bulbs.

LED lightbulbs consume up to 80% less energy than incandescent lights. They’re also more cost-effective in the long run: A 10-watt LED bulb that replaces a 60-watt bulb will save you $125 over the life of the bulb.

8. Remove the plug (s).

The outlets in your house are likely powering around 65 different gadgets when combined, which is the typical load for a home in the United States. Even when they aren’t charging, audio and video gadgets, cordless vacuums and power tools, and other electronics consume energy. This “idle load” in the United States is equivalent to the output of 50 major power plants. So disconnect seldom-used gadgets or plug them into power strips and timers when not in use, and set your computers and displays to automatically power down to the lowest power mode when not in use.

9. Get behind the wheel of a fuel-efficient car.

Gas-efficient vehicles, such as hybrids and completely electric vehicles, save both money and gas. They’ll be a mainstay until all automobiles and light trucks reach the clean car requirements of 2025, which require an average of 54.5 miles per gallon. There’s a solid reason for this: In comparison to a national fleet of cars that averaged just 28.3 miles per gallon in 2011, Americans will save $80 billion per year at the pump and reduce their vehicle emissions by half. Compare fuel economy efficiency before you buy a new set of wheels.

10. Keep your bike in good shape.

We could save 1.2 billion gallons of gas each year if all Americans kept their tires properly inflated. A simple tune-up may increase your miles per gallon by 4% to 40%, and a new air filter can increase your mileage by 10%.

11. Planes, railroads, and cars should all be rethought.

Living in walkable smart-growth communities and towns with good public transit means less driving, less money spent on gas, and less air pollution. Flying less frequently can also make a huge effect. “Air travel is a significant source of climate pollution,”

“If you can, take the train instead.”

12. Reduce your carbon footprint.

You may reduce your carbon footprint by purchasing carbon offsets, which are clean energy credits that you can use to supplement the nation’s energy system instead of fossil fuels. However, not all carbon offset firms are created equal. To locate the best provider, do your research.

Plants and animals affected by global warming

Global warming is predicted to have a significant and broad impact on the Earth’s ecosystems. According to research from the National Academy of Sciences, many plants and animals are already shifting their range northward or to higher elevations as a result of rising temperatures.

  • They’re not just heading north; they’re heading for the poles from the equator.
  • They’re merely following the comfortable temperature range, which is shifting toward the poles as the world average temperature rises.
  • Finally, this becomes an issue when the rate of climatic change velocity (the rate at which an area changes in space) exceeds the rate at which many creatures can move.
  • Many creatures may be unable to compete in the new climatic regime and may become extinct as a result.

According to the Environmental Protection Agency, migrating birds and insects arrive in their summer eating and breeding areas many days or weeks earlier than they were in the twentieth century.

  • Warmer temperatures will also increase the range of many disease-causing organisms previously restricted to tropical and subtropical climates, resulting in the extinction of formerly disease-resistant plant and animal species.
  • According to a 2013 research published in the journal Nature Climate Change, these and other impacts of global warming would likely contribute to the extinction of up to half of Earth’s plants and one-third of its animals from their existing range by 2080 if allowed uncontrolled.

Social ramifications

Climate change is predicted to have significant consequences on the natural world, but the projected changes to human society may be much more destructive.

  • Agricultural systems will almost certainly be crippled.
  • Despite the fact that some growing seasons will lengthen, the combined effects of drought, severe weather, lack of accumulated snowmelt, increased number and diversity of pests, lower groundwater tables, and the loss of arable land could result in severe crop failures and livestock shortages around the world.
  • Carbon dioxide affects plant development, according to North Carolina State University.
  • Although CO2 might help plants grow faster, it can also make them less nutritious.

According to several analyses from sources as diverse as the US Department of Defence, the Centre for American Progress, and the Woodrow Wilson International Centre for Scholars, this loss of food security could cause havoc in international food markets, sparking famines, food riots, political instability, and civil unrest around the world.

Human Health Is Being Affected by Climate Change

In addition to less nutritious food, global warming is predicted to hurt human health.

  • An increase in mosquito-borne diseases like malaria and dengue fever and cases of chronic disorders like asthma has been documented by the American Medical Association, most likely as a result of global warming.
  • The 2016 Zika virus outbreak, a mosquito-borne disease, brought attention to the consequences of climate change.

When pregnant women are afflicted, the disease causes catastrophic birth abnormalities in their fetuses. Researchers believe climate change will make higher-latitude locations more liable for the mosquitoes that carry the sickness. Longer, hotter summers may contribute to the spread of tick-borne diseases.

It is now or never! Act now as your future generation needs to be secured.
