Climate and Weather part 5

More from “The Weather of the Future”, By Heidi Cullen, Harper, 2011

Chapter 7: Central Valley, California

“Sacramento, which is among the fastest-growing cities in the United States, is the major metropolitan area at the highest risk of flooding.  The Problem is that Sacramento’s infrastructure is inadequate.”  (p. 122) (California with Sacramento marked)

I was a little confused about this at first, but then I realized that rivers flood also and Sacramento is located where the Sacramento River and the American River join.  Groundwater is only 30 feet down.  The area has historically dealt with flooding.  What surprised me was the fact that Sacramento has a deep-water port which connects it to the San Francisco Bay.  The channel is 30 feet (9m) deep, 200 feet (61m) wide and 43 miles (69 km) long.

“During the past century, the sea level along California’s coast has risen about 7 inches.”  (p. 129)

Chapter 8: The Arctic, Part One: Inuit Nunaat, Canada

“(M)any scientists believe that cultural preservation, along with housing and infrastructure improvements, is an important way to help the Inuit simultaneously tackle the issues of climate change and cultural erosion.” (p. 163)

“Average temperature has risen almost twice as fast across the Arctic as in the rest of the world during the past few decades. And it’s not just the temperature that is moving fast.  There is also a widespread melting of glaciers – and a thawing of permafrost, ground that was until now permanently frozen. Permafrost has warmed almost 3.5°F in recent decades.” (p. 166)

“Winter temperature in Alaska and western Canada has increased about 5°F to 7°F during the past fifty years.” (p. 167)

Chapter 9: The Arctic, Part Two: Greenland

“Only 500 miles from the shores of Iceland…” (p. 173)

You can see in this picture how close Greenland and Iceland are.

Quote by J.P. Steffensen, a scientist at the Center for Ice and Climate at the University of Copenhagen’s Niels Bohr Institute. “We have to get used to the word change.  That’s why we have a past, why we have a future – time is flowing forward. We should never strive to re-create the past.”

Chapter 11: New York, New York

“(A)s with Y2K, fixing the climate bug is an opportunity to be seized sooner rather than later.” (p.230)

“(W)e were missing what climate change would do to us.  (W)e had better find out how climate change is going to affect cities, because that’s where the people are.  (Cynthis Rosesnzweig) “… Rosenzweig’s research began to shift from studying the impact of climate change on nature to the impact of climate change on human nature.” (p.231)

“Cities cover less than 1 percent of the Earth’s surface, but they hold half the population and produce about 70 percent of the total greenhouse gas emissions.” (p. 231)

“For New York, climate change means blackouts.” (p. 232)

“Energy systems are generally rated for a certain temperature and power load.  If you keep running your power plant full blast for ten days during a heat wave, that’s when things begin to break down.” (p. 233)

“And as the number of hot days begins to increase, materials begin to break down: concrete, bridges, rail lines.”  “For example, the capacity to transmit electricity over power lines drops with higher temperatures due to increased resistance.”  (p. 234)

My question here is: What is different for the South?
