California

Baja California

Baja California is a desert.

Page 3: California and Climate Change

Baja California is part of Mexico.

Page 4: California and Climate Change

The ocean is never far away, yet the land is very dry.

Pacific Ocean

Southern California is also very dry.

Page 6: California and Climate Change

Southern California’s Mojave Desert

Page 7: California and Climate Change

Interstate 15 to Las Vegas—through the Mojave Desert

Page 8: California and Climate Change

However, northern California is NOT desert.

Our San Joaquin Valley

Page 9: California and Climate Change

Can you see WHY our San Joaquin Valley is not a desert??

Page 10: California and Climate Change

Here’s why!

Page 11: California and Climate Change

Snowpack in the Sierra Nevada Mountains keeps our valley lush all year!

Page 12: California and Climate Change

California was home to a large number of Native American Indian tribes

Page 13: California and Climate Change

Early settlers to California believed it to be PARADISE!

Page 14: California and Climate Change

But…how will global warming affect our San Joaquin Valley?

Page 15: California and Climate Change

To begin with, our Sierra Nevada Mountains will receive RAIN instead of SNOW.

Page 16: California and Climate Change

Why is this a problem? Isn’t rain GOOD??

Page 17: California and Climate Change

Rain flows down the mountains IMMEDIATELY, into the Delta, and out into the Pacific Ocean.

Page 18: California and Climate Change

It’s much better to have gradual snowmelt. Then we can capture it in reservoirs and have a

year-round water supply.

Page 19: California and Climate Change

As California grows, it’s increasingly difficult to supply enough water for its farms and people.

Page 20: California and Climate Change

So we drill more and more wells.

Page 21: California and Climate Change

As the water table falls, each year we must drill deeper and deeper.

Page 22: California and Climate Change

Before long, the wells go dry.

Page 23: California and Climate Change

Another consequence of global warming will be rising sea levels.

Page 24: California and Climate Change

Why will rising sea levels be a problem for us in Stockton?

Page 25: California and Climate Change

Weber Point, Stockton

Hint: Do you know the elevation above sea level of Stockton?

Page 26: California and Climate Change

Do you realize that parts of Stockton (e.g. Brookside) are already BELOW sea level?

Now please read “The Race to Save Civilization.”

What it describes is ALREADY HAPPENING here in California.
