A report of the U.S. Climate Change Science Program June 20, 2008

A joint effort of more than a dozen government agencies for the report, go online to www.usgcrp.gov www.usgcrp.gov

"Heat waves and heavy downpours are very likely to increase in frequency and in intensity.”
10
"Substantial areas of North America are likely to have more frequent droughts of greater severity.”
11
“Hurricane wind speeds, rainfall intensity, and storm surge levels are likely to increase.”
12
The strongest winter storms are likely to become more frequent, with stronger winds and more extreme wave heights."
13
Soil amplification of earthquake ground shaking is likely to be more wide spread.
14
Landslides triggered in earthquakes or by flooding are likely to be more extensive.
15
The impacts of tsunami wave run up is likely to be more extensive.
16
“By the end of this century rainfall amounts expected to occur every 20 years now could be taking place every five years.” y the end of this century rainfall amounts expected to occur every 20 years could be taking place every five years. Such an increase "can lead to the type of events that we are seeing in the Midwest," said Karl, though he did not directly link the current flooding to climate change.
17
“An increase in frequency can lead to more frequent occurrences of flooding events such as those that occurred in the Midwest during 2009 AND 2011.” y the end of this century rainfall amounts expected to occur every 20 years could be taking place every five years. Such an increase "can lead to the type of events that we are seeing in the Midwest," said Karl, though he did not directly link the current flooding to climate change.

20
Drought is the result of the interaction of rainfall, which can be highly variable, and human systems, which can be very vulnerable to changes in rainfall.
21
Drought is related to climatic variability that usually is occurring far from the community or the area being impacted by drought.

24
EARTHQUAKES EARTHQUAKES - Perspectives - Perspectives On Science, Policy, On Science, Policy, And Education And Education
26
Earthquakes occur as the result of interactions between and within tectonic plates in the lithosphere that are slowly converging, diverging, or sliding past each other as a result of stresses created by ongoing heat flow within the Earth.

Flooding occurs when the local river channels, floodplains, wetlands, and water tables are not able to contain, store, or transmit local precipitation and runoff.
