What is Climate?

When we talk about climate, the first thing that usually comes to mind is the temperature in an area. Africa typically has a high temperature and therefore, we think of it as having a hot climate. Antarctica is usually cold so it has a cold climate. Climate is an area’s average weather, including temperature, precipitation (rain, snow, etc.), humidity, wind, and even seasons. The problem we face now is human-made climate change. What we are doing is changing our climate much faster than Nature intended and that's what’s causing the problems.

Climate Data

• We are about to look at Earth’s global average surface temperature from 1880 - 2020. But before we do that we should understand some key vocabulary and how to read the visual data.

After looking at NASA's data on Earth's average surface temperature from 1880 to 2020, comment on 2 - 3 things that you noticed.

Multiple Choice

According to that data from NASA, has the Earth's average surface temperature been increasing or decreasing?

• increasing

• decreasing

Greenland Ice Sheet

A large part of Greenland is covered by an ice sheet.

Greenland has been losing large amounts of ice into the sea

The volume of ice lost could fill rafts the size of 14 states 3 feet thick!!

Greenland Ice Sheet

Earth's warming climate causes the ice sheet to melt at a rapidly accelerating rate.

This melting ice enters the ocean, causes rising global sea levels.

Rising Sea levels cause flooding and other damage to coastal communities.

What were some things you noticed in the last video?

We have seen evidence that Earth's average temperature is increasing and in fact the globe as a whole is getting warmer. After watching the last video what are some questions you have or some questions you could ask to find out more about what is causing these rising temperatures?

Are global temperatures actually rising, if so why?
