Answer 9

Has Increased

Question 11

Answer 11

• increasing sea surface temperatures
• ocean acidification
• shifts in currents
• wind patterns

Question 13

Who said?

“a government by the people, of the people, and for the people”

Answer 13

Abraham Lincoln

Question 14

What does it mean when we say?

“a government by the people, of the people, and for the people”

Answer 14

which illustrates the benefits of democratic
participation and helps conceptualize viable
alternatives.

Question 15

The world is groaning; humanity is in
danger due to the global connection is greatly
responsible for its devastation

Answer 15

Climate Change

Question 16

potentially accountable for Earth’s
restoration?

Answer 16

Global Connection

Question 17

Can be learned collectively.

Answer 17

Adaptation and Mitigation

Question 18

6 ways climate change will affect PH cities

Answer 18

• More intense El Niño
• Sea surface temperatures to rise
• Ocean acidification
• Sea levels to rise by 4 to 6 meters
• Tropical cyclones to intensify
• Rainfall, river flow and flooding to intensify

Question 19

phenomenon occurs when the
surface of ocean waters in the southern Pacific becomes abnormally warm. The energy created by this warming is so great that it can create an imbalance in the weather in different parts of the world.

Answer 19

El Niño

Question 20

Are expected to rise by 1 to 4 degrees
Celsius. This can lead to more powerful storms because storms get their strength from heat rising from the sea.

Answer 20

Sea surface temperatures to rise

Question 21

The shift in the Ph levels of our oceans can lead to widespread coral reef death. Because of the imbalance, shrimps are not able to develop skins, oysters cannot develop shells. Fish larvae may not be able to develop bones. This further endangers food security and the livelihood of fishermen.

Answer 21

Ocean Acidification

Question 22

Current data show an increase in sea surface
heights. Scientists say this is due to the melting of ice sheets in northern portions of the globe like Antarctica and Greenland. Sea level rise by 4 to 6 meters can submerge low-lying communities like Tacloban City which stands only 3 meters above sea level.

Answer 22

Sea levels to rise by 4 to 6 meters

Question 23

The creation of tropical cyclones is already
being recorded in areas where the phenomenon had never been observed. On Nov 8, 2013, Super Typhoon Yolanda (Haiyan), said to be the strongest storm in recorded history, devastated cities in Visayas.

Answer 23

Tropical cyclones to intensify

Question 24

Monsoon rainfall in the Philippines will reach
new highs and lows. Some parts of the country will experience an upward trend in rainfall while other parts will experience an intensification of drought. These two
extreme poles of weather will make it more difficult for agriculture and aquaculture sectors which are highly dependent on weather.

Answer 24

Rainfall, river flow and flooding to intensify

Question 25

Are designed to simulate the responses and interactions of the oceans and atmosphere, and to account for changes to the land surface, both natural and human-induced.

Answer 25

Climate Models

Question 26

Greenhouse gases are only part of the story when it comes to global warming. Changes to one part of the climate system can cause additional changes to the way the planet absorbs or reflects energy. These secondary changes are called?

Answer 26

Climate Feedbacks

Question 27

The primary feedbacks are due to?

Answer 27

snow and ice, water vapor, clouds, and the carbon cycle.

Question 28

•Perhaps the most well known feedback comes from melting snow and ice in the Northern Hemisphere. Warming temperatures are already melting a growing percentage of Arctic sea ice, exposing dark ocean water during the perpetual sunlight of summer. • __________ cover on land is also dwindling in many areas. In the absence of snow and ice, these areas go from having bright, sunlight-reflecting surfaces that cool the planet to having dark, sunlight-absorbing surfaces that bring more energy into the Earth system and cause more warming.

Answer 28

SNOW AND ICE

Question 29

• The largest feedback • is a strong greenhouse gas. In fact, because of its abundance in the atmosphere, water vapor causes about two-thirds of greenhouse warming, a key factor in keeping temperatures in the habitable range on Earth. But as temperatures warm, more water vapor evaporates from the surface into the atmosphere, where it can cause temperatures to climb further.

Answer 29

Water Vapor

Question 30

• Closely related to the water vapor feedback is the cloud feedback • cause cooling by reflecting solar energy, but they also cause warming by absorbing infrared energy (like greenhouse gases) from the surface when they are over areas that are warmer than they are.

Answer 30

Clouds

Question 31

• Increased atmospheric carbon dioxide concentrations and warming temperatures are causing changes in the Earth’s natural ____________ that also can feedback on atmospheric carbon dioxide concentration

Answer 31

The Carbon Cycle

Question 32

• Scientists predict the range of likely temperature increase by running many possible future scenarios through climate models. • Although some of the uncertainty in climate forecasts comes from imperfect knowledge of climate feedbacks, the most significant source of uncertainty in these predictions is that scientists don’t know what choices people will make to control greenhouse gas emissions

Answer 32

Emission Scenarios

Question 33

Where have some of the strongest and earliest impacts of global warming occurred?

Answer 33

Northern Latitudes
