Climate change is caused by abiotic and biotic factors.
The climate has changed over time.
Many of the changes were caused by small variations in the Earth's position around the sun.
The amount of solar energy received by various regions shifted.
The current changes to the Earth's climate are most likely human-caused and occurring at a faster rate than the past 1,300 years.
When the Earth's atmosphere traps the heat that should be returned to space, this is a warming trend.
Water vapor, carbon dioxide, nitrous oxide, chlorofluorocarbons, and methane are some of the gases that contribute to the greenhouse effect.
As the Earth's atmosphere warms, it produces more water vapor.
The feedback mechanism associated with the greenhouse effect is formed by the retention of additional heat that should have been sent back into the atmosphere.
Consider how warm a summer night is if there is an abundant cloud cover.
Figure 45.22 shows how carbon dioxide is released through processes such as cellular respiration and decomposition and then absorbed through photosynthesis and stored in the bodies of the organisms.
Fossil fuels have significant amounts of carbon in them.
The burning of fossil fuels has created an imbalance in the carbon cycle by releasing more carbon dioxide than can be absorbed.
Modern agricultural practices include the burning of fossil fuels and the production of nitric acid.
There are a wide variety of commercial and residential applications for chlorofluorocarbons.
The destruction of the ozone layer has been aided by the destructive nature of chlorofluorocarbons.
Natural and human activities produce methane.
Page 869 is contributing to global climate change as humans alter landscapes.
On a global scale, deforestation is occurring at an alarming rate.
It deprives the forest of the canopy when large regions of forest are cleared.
This causes the soil to dry out, preventing the growth of new trees.
The regions can become more desertlike due to the lack of mature trees.
Millions of tons of carbon dioxide are released into the atmosphere when the trees are burned.
Climate change is caused by rain forest destruction.
Within the next hundred years, the world's rain forests could be gone.
The scientific community believes that human activities are the main cause of the climate changing events currently being experienced by the Earth.
Over the past 150 years, atmospheric levels of carbon dioxide have increased due to industrial activities that are necessary to support modern society.
Climate change is expected to have a wide variety of consequences.
The Intergovernmental Panel on Climate Change predicts that the Earth's temperature will increase between 2.5 and 10degF in the next century.
Over 1,300 scientists from the United States and other countries make up the IPC.
They think that the rise in temperature may benefit some regions and hurt others.
The growing season will begin earlier in some regions.
This could mean that crops will be planted earlier with the possibility of increased harvests.
Changes in precipitation patterns may affect the potential for longer growing seasons and increased harvests.
California has been experiencing a severe dry spell for most of the past several years.
Major flooding resulted in significant environmental and property damage after a period of intense rains.
Climate change has made hurricanes and other precipitation events stronger and more intense.
The North Atlantic region has seen an increase in the number of Category 4 and 5 hurricanes.
The storm intensity associated with hurricanes is projected to increase.
The Louisiana flood of 2016 was the worst natural disaster to hit the United States since Hurricane Sandy.
As the Earth's temperatures continue to increase, it is predicted that there will be a decrease in the amount of ice found in the northern part of the planet.
The decrease in ice pack and the warming of the ocean has led to a global increase in sea level.
Projections show that the sea level will rise between 1 and 4 feet by the year 2200.
Major coastal cites like Miami, New York, and New Orleans are expected to be flooded by this increase, along with stronger storm surge and higher tides.
Everyone is responsible for contributing to the issue of climate change.
In developed countries like the United States, Germany, and Great Britain, individuals play a larger role in the production of greenhouse gases.
It is up to each of us, individually, to make small changes that can add up to large scale benefits towards decreasing the impact of climate change.
Small changes at home that can help reduce your personal impact and contribution to climate change include things like replacing light bulbs with ENERGY STAR products.

Scientists around the world are working on collecting and interpreting environmental data that will help them understand how and why the Earth's climate is changing.
The United States has seen an increase in the average temperature since 1901, with the most recent decade being the warmest on record.
Over the past century, precipitation rates have increased.
States have had 8 of the top 10 years of extreme precipitation.
A more active Hurricane season is caused by increases in sea surface temperatures.
The Atlantic Ocean, the Caribbean, and the Gulf of Mexico have seen 6 of the 10 most active hurricanes.
Sea levels have risen an average of 1 inch per decade due to the increase in the surface temperature of the world's oceans.
Climate models show a rise in sea levels of 3 to 4 feet over the next century.
The Florida Keys are an average of 3 to 4 feet above sea level, while New York City is an average of 5 to 16 feet above sea level.
Even if the rising waters don't cause flooding, many coastal areas will be exposed to storms and storm surge that could lead to significant economic losses.
China and the EU are the second and third largest producers of carbon dioxide emissions per person.
The global problem we are facing requires global cooperation in order to be solved.
The Kyoto Protocol entered into force on February 16, 2005. stabilization and reduction of the greenhouse gas concentrations in the atmosphere was the goal of the protocol.
The goal of the protocol is to reduce emissions by an average of 5.2% by the year 2012.
There are concerns that the United States will no longer participate in the structure of the agreement if we don't ratified the agreement.
Many developed nations agreed to raise 30 billion dollars to help poor nations cope with the effects of climate change.
The UN Climate Change Conference in Warsaw was successful in establishing ways to help developing nations reduce greenhouse emissions as well as establishing finance commitments to assist developing nations.
The Paris Climate Change conference was the most successful of the meetings to date.
The Paris agreement would limit greenhouse emissions to levels that would keep the increase in global average temperature to less than 2degC over preindustrial levels.
The main concern of the conferences is that the hard decisions of making significant changes to our greenhouse emissions continue to be pushed off into the future.
The higher the risks, the longer we delay in making changes.
Changes in global climate patterns have been caused by increased CO2 emissions in the past hundred years.
The United States produces more CO2 per person than China.

Correcting the problems that are causing climate change are not things that can be solved quickly, but without making some form of concerted efforts, we can be sure that the problems we face will only continue to get worse.
Three factors are contributing to climate change.
Increased niche specialization occurs when resources are partitioned between two or more species.
When warblers feed at different parts of the tree canopy, the difference between species can be more subtle.
There are barnacles on the Scottish coast.
The amount of resources available for the prey and the size of the predator population affect this type of interaction.
Population densities may change.
One species has the warning color but lacks the defense.
Mullerian mimicry occurs when two species have the same defense.
If parasites are benign or aggressive, it depends on which results in the highest fitness.
When a relationship benefits both species, mutualism occurs.
There is no soil present where the primary succession occurs.
When soil is present, certain plant species can grow.
The types of soil and temperature are some of thebiotic components.
Energy flow and chemical cycling are part of the ecology.
Each population makes energy conversions that result in a loss of usable energy when food passes from one population to the next.
Chemicals are passed from one population to the next until they are returned to the producers.
Food chains begin with trash.
Chemical cycling involves a community.
There are bodies of fresh water and underground water in the result of precipitation over land.
