What is the video all about?

We hear it so much that it feels like a buzzword but it is far from it. is a real and serious issue. But isn't the climate always changing? What exactly is climate change? Why should we care? Well, the Earth's climate has changed throughout history. Most of these slight changes are caused by in the Earth's orbit. But climate change as we know it today, is characterized by . It is estimated to have gotten 1.2 to 1.4 degrees Fahrenheit warmer in just the last century. 10 out of the last 13 years were the warmest on record. 97% of climate scientists agree that this new tendency is not caused by the variations of the Earth's orbit but rather very likely caused by . That means YOU, and ME! And since the Industrial Revolution, we have come a long way. Humans built airplanes, faster cars, developed remarkable technology, and learned how the natural resources around us can be used for our benefit, although this has led to like the device you're using to watch this video or the ability to take a plane halfway around the world. It also means we've increased our consumption of natural resources and in turn, released a lot of into the atmosphere. Now, greenhouse gases occurred naturally, but in excess can be dangerous to our planet. Modern human activities have increased the release of non-naturally occurring greenhouse gases because we have stepped up our demand for . The composition of greenhouse gases traps heat radiated from the sun. The more heat they trap, the warmer our planet gets and as our planet gets warmer, we begin to feel the effects. One of climate changes biggest victims is our oceans. Oceans regulate through earth's temperature and provide 50 percent of the Earth's oxygen. A climate change has increased the of the oceans by more than 0.3 degrees Fahrenheit since 1969. Although a warmer ocean might seem inviting to a beach goer, it actually has devastating consequences for supporting life at sea.

One of those consequences is , a direct effect of increased dissolved CO2 since the late 18th century, ocean surface acidification has increased by 30%. A means calcifying species like oysters and clams and shell water corals are at risk - putting the entire ocean food web at risk. This is bad news for the one billion people relying on the ocean as its primary source of . Climate changes also caused the sea level to rise. Just in the last century, sea levels have risen six point seven inches but the rate in the last decade, has nearly doubled. Sea levels have risen because as the ocean gets warmer, it . On top of that, are melting. An article lost 36 cubic miles of ice between 2002 and 2005 and since 1994, each year on average, the earth has lost 400 billion tons from its glaciers. That's like an ice cube seven and a half kilometres on a side, four miles on a side - melting and flowing into the sea. When all that ice melts, it fills up our oceans and just like filling up a bathtub, the shores can't hold all that water and get flooded. Troubling signs of climate change are increased extreme weather events. like floods, tornadoes, and deadly heat waves are more obvious to humans because of their immediate impact and their sharing of the images in the media. Climate change as we know it today is change in our with massive and permanent . Although its consequences can be planet threatening, scientists still believe there are things we can do on a personal level to help -- recycle and reuse things; walk or use public transportation to get to work; turn off your electronics when you're not using them; eat less meat - while you're at it, eat more locally-grown vegetables and foods; and last but not least, about climate change with others. When it comes to climate change, the main takeaway is that it's real and although we are part of the cause, we can also be part of the solution.
