Climate change? Global warming? What do we call it?

Both are accurate, but they mean different things.

You can think of global warming as one type of climate change. The broader term covers changes beyond warmer temperatures, such as shifting rainfall patterns.

It ..^V.. that scientists stopped referring to global warming and started calling it climate change because “the weather has been so cold” in winter. But the claim is false. Scientists have used both terms for decades.

How much is the Earth heating up?

Two degrees is more significant than it sounds.

As of early 2017, the Earth had warmed by roughly 2 degrees Fahrenheit (more than 1 degree Celsius) since 1880, when records began at a global scale. The number may sound low, but as an average over the surface of an entire planet, it is actually high, which explains why much of the world’s land ice is starting to melt and the oceans are rising at an accelerating pace. If greenhouse gas emissions continue unchecked, scientists say, the global warming could ultimately exceed 8 degrees Fahrenheit, which would undermine ..^VI.. to support a large human population.
