If we reduced the rate that we add carbon dioxide to the atmosphere from 10.6 to 9 gigatons of carbon per year, how would Earth's global temperature change?

The diagram below represents the Earth's heat flow.

#1 Heat Flow In: heat coming from the sun

#2 Heat Flow Out: Heat being release back into space from the Earth

#3 Heat Flow Out being interrupted by greenhouse gases, causing heat to be trapped in the atmosphere.

If the amount of greenhouse gases increase in the atmosphere, which variable would NOT change?

The average temperature of the Earth's surface has increased by about 2 degrees Fahrenheit (1 degree Celsius) since the late 1800s.

What is the primary cause for this change?

Match the greenhouse gas to the correct description

Match the greenhouse gas to the correct description

Without the greenhouse effect, what would Earth's temperature be like?

Which communities often face the worst effects of climate change?

Why is the community you selected in the previous question more affected by climate change than others?

What produces the majority of Washington's greenhouse gases?

What is a major consequence of the decreasing amounts of sea ice at the North Pole?

Which organism that is essential to the culture of the Swinomish and other Washington tribes is being threated by climate change?

What is the primary source of greenhouse gases?

What is a major source of methane emissions?

Earth's global temperatures have risen and fallen in the past.

How does the rate of today's global temperatures compare to the past?

Modern instruments have only been around for a little over 100 years.

So how do we know what greenhouse gas concentrations (and temperature) were in Earth's past?

In some parts of the world, rainstorms have become more intense over the past several decades. Is that a change in weather or climate?

When you hear it’s unusually hot today, is that about the climate or weather?

What consequence of climate change is threatening Washington's salmon populations?
