But in some parts of the world it is less than this and some more. Called greenhouse gases, their levels are higher now than at any time in the last 800years. Over the past years, the average global temperature has increased at the fastest rate in recorded history.

See full list on nrdc. And scientists say that unless we curb global-warming emissions, average U. Fahrenheit over the next century. Normally, this radiation would escape into spacebut these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. Coal-burning power plants are by far the biggest polluters.

The countrys second-largest source of carbon pollution is the transportation sector, which generates about 1. Curbing dangerous climate change requires very deep cuts in emissions, as well as the use of alternatives to fossil fuels worldwide. COemissions a year. Likewise, while under the Obama administration, the U. The earths ocean temperatures are getting warmer, toowhich means that tropical storms can pick up more energy.

So global warming could turn, say, a category storm into a more dangerous category storm. The impacts of global warming are being felt across the globe. Extreme heat waves have caused tens of thousands of deaths around the world in recent years.

Fortunately, state leadersincluding in car country itselfrecognize that clean transportation must remain a priority if we are to address the costly risks of climate change and protect public health. Our clean energy economy is growing too, despite federal efforts to derail it. To help make the deal happen, the Obama administration pledged $billion to the Green Climate Fun an international organization dedicated to helping poor countries adopt cleaner energy technologies.

Even better, a new initiative by former New York City mayor Michael Bloomberg gives the urban layer of this movement a boost. Hes asked mayors from the 1most populous cities in the country to share their plans for making their buildings and transportation systems run cleaner and more efficiently.

The that show the greatest potential for cutting the dangerous carbon pollution thats driving climate change will share a total of $million in technical assistance funding provided by Bloomberg Philanthropies and partners. A: Wondering how to stop global warming?

Reduce your own carbon footprint by following a few easy steps. Make conserving energy a part of your daily routine and your decisions as a consumer.

When you buy a car, look for one with the highest gas mileage and lowest emissions. You can also reduce your emissions by taking public transportation or carpooling when possible. And while new federal and state standards are a step in the right direction, much more needs to be done.

Voice your support of climate-friendly and climate change preparedness policies, and tell your representatives that transitioning from dirty fossil fuels to clean power should be a top prioritybecause its vital to building healthy, more secure communities. Some parts of Earth are warming faster than others.

In fact, the past five years have been the warmest five years in centuries. Many people, including scientists, are concerned about this warming. A greenhouse (or glasshouse) is good for growing things because it traps heat inside and stays hotter than the atmosphere around it. Global warming is caused by a phenomenon known as the greenhouse effect.

It has to do with the overall climate of the Earth rather than the weather on any given day. History of Global Temperatures The Earth has gone through changes in temperature before. Scientists are more than 95% certain that nearly all of global warming is caused by increasing concentrations of greenhouse gases (GHGs) and other human-caused emissions.

Global Warming Glaciers melting – Many glaciers are already melting and shrinking throughout the world. If the temperature increases. Ocean levels will rise – As the glaciers melt, the ocean levels will rise. This could cause flooding in cities located.

Migration of animals – Animals will. And the explanation is really very simple. Carbon has sources and sinks. A source adds Cto the atmosphere, a sink removes it.

Some of the big sinks are trees and plant life (they breath C02), and the oceans. Climate change (or global warming), is the process of our planet heating up. Scientists estimate that since the Industrial Revolution, human activity has caused the Earth to warm by approximately 1°C. While that might not sound like much, it means big things for people and wildlife around the globe.

Contents Human factors contribute Research version 3. Comprehensive and meticulously documented facts about global warming. Learn about greenhouse gases, global temperatures, causes and effects, politics, and more.

Although global warming is connected to scary scenarios featuring soaring temperatures and worsening hurricanes and monsoons, it’s also a link to a better future. The temperature of the earth is increasing significantly after 20th Century when there was the start of the industrial era which is known to be the most responsible for this cause.
