Global Warming Global Warming is the increase in temperature across the earths surface over time.

Glossary

Greenhouse gases: a gas that can hold in heat which leads to the atmosphere to become hot.

Consecutive: continuously or happening repeatedly.

Revise: reconsider or change something due to new ideas brought to light.

Temperature: the amount of heat trapped in a substance measured by a thermometer.

Retain: to hold in.

Deforestation: the reduction in size of native vegetation.

Bill Nye explains the effects of climate change, an effect of increased surface temperature on Earth otherwise known as global warming.

Why Should We Be Concerned About Global Warming?

Global warming can have many devastating effects, this can range from drought to floods with the ability to reach new and more dangerous results. Actually “A study published in the scientific journal Nature Climate Change in 2015 predicted lethal heatwaves would ‘routinely sweep the region by 2070’, that people could die within six hours without air-conditioning and it would be so hot machinery could malfunction and aircraft would be unable to take off.” says Shahlaa Ahmed a publisher at TCA Regional News. The tremendous heat would not just come in waves but in constant force all year around the world. “The warming was truly global. ‘Some part of every continent, and some part of every major ocean basin was warmest on record,’ Arndt says, adding that in the United States, only Georgia and Alaska had record-setting warmth but ‘pretty much the entire country was above normal, and well above normal.’” according to Nell Greenfieldboyce an NPR science correspondent. This record-setting warmth may feel like it's a gradual thing that progresses slowly over time, but scientists claim it's been accelerating for years.

Why Has Global Warming Been Accelerating?

The rapid emission of carbon dioxide into the air has caused surface temperatures on Earth to rise. Scientists have proven the emission rates have been increasing for a while. In fact, “Ever since the industrial revolution began factories, power plants, and eventually cars burn fossil fuels such as oil and coal releasing huge amounts of carbon dioxide and other gases into the atmosphere” states National Geographic's video on global warming. This has been happening for a long time until we realised the harm it did to the atmosphere, so we started to change to clean coal and healthy energy alternatives. But these alternatives haven’t been the answer for the crisis we still face today. “When the researchers corrected the data to take this "cold bias" into account, they concluded that the oceans had warmed 0.12C per decade since 2000, nearly twice as fast as previous estimates of 0.07 degrees.” says Matt McGrath, a environment correspondent at BBC news. Switching away from fossil fuels to alternative or green energy may seem like an easy thing to do but why don't we do it?

How Can We Slow Global Warming and Lower Our Carbon Dioxide Footprint on the World?

We can slow global warming and lower our carbon dioxide output by consuming and using less fossil fuels while also reducing the amount wasted energy. In reality “Many organizations advocate cutting greenhouse gas emissions to reduce the impact of global warming. Consumers can help by saving energy around the house switching to compact fluorescent light bulbs and driving fewer miles in the car each week. These simple changes may help keep the earth cooler in the future” says National Geographic's informative video on the issue of global warming. If people start to make these changes it can inspire others to do the same so we can make a difference. Businesses commonly adapt to popular trends in the public if they see how serious we are. “We need to protect and preserve the Arctic by creating a global sanctuary for the uninhabited regions of the Arctic. The oil and gas reserves need to stay put under the seabed. We can’t afford to burn more fossil fuels. If the Obama administration seriously wants to tackle climate change, it needs to stop violating international climate commitments.” claims Faiza Oulahsen an activist at Greenpeace. Slowing our carbon footprint seems simple enough but what would happen to us if we didn’t make the change.

How Would Global Warming Affect Daily Life?

Global warming would negatively impact many necessary utilities we need to survive on a daily basis. Such as increases in natural disasters like wildfires, flooding, etc. More problems like “Drought will also cause water shortage and serious damage to agriculture.” says Shahlaa Ahmed a member of TCA Regional news. Rising surface temperatures can cause an array of problems on land. But what happens to those that have homes near the shore would face an even bigger problem. “If the Earth's climate warms by 2 or 3 more degrees by 2100, global sea level will rise 3 feet, displacing almost 56 million people around the world” states Suzanne Didier an online publisher whose work has appeared on National Geographic's website. This information can be very profounding to people but the data being used to tell us how global warming is happening can now be reassuring to some.

How can Global Warming be Measured by Scientists?

Scientists are able to measure the speed of rising surface temperatures by measuring the amount of carbon dioxide in the atmosphere or by taking the temperature of the surface of earth. We can measure carbon dioxide in ways such as land, water, and air samples. “Ingredients taken from ice cores show that the greenhouse gases carbon dioxide and methane have hit their highest levels in the past 420,000 years” mentioned national geographic's video on global warming. High levels of carbon dioxide and methane are greenhouse gases that cause the earth to heat up. There has been debate whether the earth has actually been getting hotter but recent studies show past data was multiple data sets mashed into one. “Back in the 1990s, ship measurements made up the vast majority of the data, whereas now the more accurate and consistent buoys account for 85% of measurements” state's Matt McGrath an environmental correspondent for BBC News. This means that faulty evidence for global warming will hopefully be no more and can be factually proven and accepted by all so we can make a change to stop global warming.
