What Is Climate Change, Bill Nye?

We hear about climate change all the time, but what exactly is it?

Posted on

"Climate change is characterized by an abrupt increase in the Earth's temperature."

National Geographic

Earth's temperature "is estimated to have gotten 1.2 to 1.4℉ warmer in just the last century."

National Geographic

"10 out of the last 13 years were the warmest on record."

National Geographic

97% of climate scientists say climate change is caused by human activities.

National Geographic

Since the Industrial Revolution, we have "learned how the natural resources around us can be used for our benefit."

National Geographic

Our increase in consumption has led to the increase of greenhouse gases we emit into the atmosphere.

National Geographic

"Modern human activities have increased the release of non-naturally occurring greenhouse gases" due to burning fossil fuels.

National Geographic

"The composition of greenhouse gases traps heat radiated from the sun." More trapped heat = warmer planet.

National Geographic

"As our planet gets warmer, we begin to feel the effects."

National Geographic

"One of climate changes biggest victims is our oceans."

National Geographic

"Climate change has increased the global temperature of the oceans by more than .3℉ since 1969."

National Geographic

A warmer ocean "has devastating consequences for supporting life at sea."

National Geographic

A 30% increase in ocean acidification "means species are at risk," which affects the entire ocean food web.

National Geographic

"This is bad news for the 1 billion people relying on the ocean as its primary source for protein."

National Geographic

"Climate change has also caused sea level to rise 6.7 inches just in the last century, but the rate in the last decade is nearly double."

National Geographic

One reason sea level is rising is because "glaciers and ice sheets are melting."

National Geographic

"Troubling signs of climate change are increased extreme weather events."

National Geographic

So what can we do?

Recycle and reuse. Walk or use public transportation. Turn off your electronics. Eat less meat. Eat more locally grown foods. Spread your knowledge about climate change with others!
