What Is Climate Change?

Climate change happens when a location’s usual weather is altered. This could be a change in rain levels or usual temperatures. Climate change is also a global phenomenon, including changes in global temperatures or where snow falls on the planet. Climate change takes hundreds to millions of years. 

In one sense, Earth’s climate changes frequently. There have been times in history when Earth’s climate has been warmer and times when it has been cooler. These eras can last for an era or an eon.

Current climate change scientists say that the Earth’s temperature has gone up about one degree (F) during the last century. Though it doesn’t seem like a big deal, even small changes in global temperatures can cause big changes.

We are seeing evidence of the Earth’s Warming right now, with rising oceans and altered life cycles for certain plant life. 

American scientists have been involved in a concentrated effort to determine how quickly our current technology can be deployed to slow and stop global warming.

The researchers looked deep into the specifics of converting from fossil fuels to clean energy. Numbers show that about four-tenths of one percent of America’s landmass could produce renewable, solar energy. But to make that work, we would need to build the factories necessary to churn out thousands of acres worth of solar panels, as well as wind turbines and electric cars and buses.

It’s important to remember that global mobilization to rout climate change would provide a host of economic and social benefits. Deaths from air pollution would be greatly reduced and there would be safer, better-paying employment for energy workers.

In America, a widespread campaign has stymied Arctic drilling and banned fracking in key states. Cities and counties are building more bike paths. Legislators and lobbyists are proposing several ideas, including a carbon tax, a worldwide fracking ban, mandating that federal agencies get their power from green sources, and a prohibition against mining or drilling on public lands.

Should these initiatives be implemented, major fossil fuel companies face the risk that large parts of their reserves will be worthless, leaving BHP Billiton, Anglo American, and Exxaro’s coal reserves in the ground and BP, Lukoil, ExxonMobil, Gazprom and Chevron’s huge gas and oil reserves untapped.

If the nations of the world honor their pledge to fight climate change, the prospects are dreariest for coal, the mother of all polluting fossil fuels. Eighty-two percent of the global supply would have to stay underground.

For gas, 50% of global reserves would have to remain unburned. Geographical variations mean that colossal gas producers in Russia and the Middle East must leave huge quantities underground, while the US and Europe can use more than 90% of their reserves in place of coal.

And while the politicians and policy makers bicker about the solutions for the future, progress had been made in several areas: cutting ozone-damaging chemicals and increasing energy from renewable sources – but these are small steps.

Nevertheless, in the past 25 years, according to the UK’s Independent:

The amount of fresh water available per head of population worldwide has reduced by 26%.
The number of ocean “dead zones” – places where little can live because of pollution and oxygen starvation – has increased by 75%.
Nearly 300 million acres of forest have been lost, mostly to make way for agricultural land.
Global carbon emissions and average temperatures have shown continued significant increases.
Human population has risen by 35%.
Collectively the number of mammals, reptiles, amphibians, birds and fish in the world has fallen by 29%.
Conclusion
The evidence is overwhelming. The burning of oil and other fossil fuels have had a significant impact on the environment. And while oil and coal companies have made efforts to encourage development of cleaner, renewable energies, they still rely on their mainstay products.

The generations inhabiting the Earth in 2018 may or may not see any significant climate changes in their lifetimes. The goal is to preserve the planet for the generations yet to come.
