Climate change
In general, precipitation falls on the ? ? Side of mountain ranges
Windward
Predict what will happen to precipitation patterns around the world as a result of climate change
In some areas, precipitation will probably increase, but in other areas, precipitation will probably decrease
What do scientists believe is the main cause of global warming
The increase of greenhouse gases in the atmosphere
Scientists can extract samples of ancient air from ice core. True or False
True
The United States has not signed the Kyoto protocol . True or False
True
Warm water is drawn away from the equator towards the poles by
thermohaline circulation
Elevation and the presence of features such as mountains and rivers make up an area's
topography
Global warming is only aspect? ? Which refers to many characteristics such as temperatures, rainfalls, wind patterns and storms frequency
Global climate change
Gases such as water vapor and carbon dioxide that trap heat near earth are known ass
Greenhouse gases
About what percent of the fuel burned by automobile actually moves the car down the road
14%
What killed about 35,000 people in Europe in 2003
A severe heat wave
How does the greenhouse effect work?
Greenhouse gases in the atmosphere sunlight pass through and when the sunlight reaches earth Surface, much its energy is converted to heat and retaliated back into the atmosphere where some of it absorbed by greenhouse gases thus keeping earth warm
During? ? Equatorial winds weaken and the surface water in the eastern pacific oceans becomes warmer than usual, which has major effect on weather worldwide
El Niño
What is the largest source of United States greenhouse gases
Electricity generation
Generally, the farther a place is from the equator, the warmer its climate climate will be. True or False
False; cooler
One indicator of global warming is that sea levels are dropping in many parts of the world. True or False
False; rising
As oceans temperatures increase, the amount of carbon dioxide dissolved in oceans water has deceased. True or False
False;increasing
How do volcanic eruptions affect weather?
Gases and particles may block sunlight and lower temperatures.
What are two weaknesses of using carbon offsets
It is often difficult to establish effective systems of exchange, and the offset may not accomplish what it is intended to do
What is one of the criticisms of the Kyoto Protocol
It only requires developed nations to reduce emissions.
How was the Kyoto Protocol an improvement over the United Nations Framework Convention on Climate Change
It was binding not voluntary
A carbon? ? Is a voluntary payment made when one industry or person, instead of reducing its own greenhouse gases emissions, pays another group or person to do so
Offset
Minor changes in earths? ?and in the tilts of earths surface axis can affect the distribution of solar radiation over earths surface and cause climate changes that can last for thousands of years
Orbit
How was global warming made it more difficult for polar bears to hunt seals they feed on
Polar bears are forced to swim longer distance between ice sheets
To learn what climate were like in the past scientist investigate the following types or indirect evidence that serve as substitutes for Direct measurement
Proxy indicators
What was happened to global precipitation patterns during the last 100 years
Some parts of the world are seeing more precipitation than ever before while others are parts are seeing less
Prevailing winds move
Warm air away from the equator
Name one effect thermohaline circulation has on weather
Warm surface water flowing northward from the equator carries heat toward Europe keeping it warmer than it would otherwise be.
Which human activity contributes the most carbon dioxide to the atmosphere
burning fossil fuels
Factory A is allowed to release 100 units of carbon dioxide, but it only needs to release 75 units, so it plans to sell its 25 extra allowances to Factory B. What type of program does this demonstrate
cap and trade
