CLIMATE CHANGE

A.

Causes of Cl!a"e C#a$%e

`There are several causes of climate change on the planet due to global

warming . including the greenhouse gases responsible for warming , and

humans emit them in various ways . Most come from burning fossil fuels in

cars, factories and power production. gas that is responsible for most of the

warming is carbon dioxide , also called CO2. Other contributors include

methane released from landfills and agriculture especially of the digestive

system of gra!ing animals " , nitrous oxide from fertili!ers , gases used for

refrigeration and industrial processes , and the loss of forests that would

otherwise store CO2 .

mountain glaciers, ice sheets covering &est 'ntarctica and (reenland, and'rctic sea ice.

)esearcher *ill +raser has traced the decline of the 'd-lie penguins on

'ntarctica, where their numbers have fallen from 2,/// breeding pairs to00,/// in / years.

1ea level rise became faster over the last century.

1ome butterflies, foxes, and alpine plants have moved farther north or to

higher, cooler areas.

recipitation rain and snowfall" has increased across the globe, onaverage.

1pruce bar beetles have boomed in 'lasa thans to 2/ years of warm

summers. The insects have chewed up 3 million acres of spruce trees.

could add between 3 and 5 inches 0/ to 2/ centimeters".

8urricanes and other storms are liely to become stronger.

1pecies that depend on one another may become out of sync. +or

example, plants could bloom earlier than their pollinating insects become

active.

where droughts are already common, could decline by 0/ percent over the

next 6/ years.

thousands of people who rely on it for drining water and electricity

without a source of either.

E$e(%* 'o$se(-a"o$ will show the earliest paybac in terms of CO2

reductions > in many cases an investment in energy conservation made

this year will show CO2 reductions this year, and every year thereafter.

*ecause we?ve been living in a world of artificially cheap energy for

decades, there are huge opportunities for energy conservation.

Re$e,ale e$e(%* including energy from wind, solar, wave, biofuels,etc., substitutes directly for fossil fuels and eliminates CO2 emissions

entirely. ' small note of caution is needed > in a few cases, most

notoriously certain biofuels, a large amount of energy input is re;uired to

create renewable energy, in some cases even exceeding the resulting

energy output. Most renewable energy, however, is extremely efficient,

and is poised to grow in importance due to the rising costs of fossil fuels.

#n many places where governments have stepped in to help this process

along, renewables are already playing an important role.

Se/ues"(a"o$, or the long>term trapping of carbon dioxide before it

enters the atmosphere, is an intermediate step along the way, but is not a

solution in and of itself. Carbon dioxide can be se;uestered as a gas by

pumping it underground or into the ocean, or it can be se;uestered by

plants > however carbon se;uestered by plants is, in most cases, ;uicly

released to the atmosphere again. The global carbon budget of plants can

be changed to se;uester a greater amount of CO2 from the atmosphere,

but so far we have been doing the opposite > cutting and burning forests

for instance has released vast amounts of CO2 into the atmosphere, and

poor agriculture has resulted in CO2 being released from the soil. 1ome

of these changes are reversible in the long run.
