We should reduce the use of fossil fuels
For	Against
(co) Global warming is bad for the environment The extensive use of fossil fuels contributes significantly to the global warming the use of fossil fuels is a major source of pollution	fossil fuels can be non-polluting the world economy is based on energy from fossil fuels, so reducing their use would damage the economy

For	Against
increased melting will quickly drain up water rivers in particular region of which water sources of dry season rely upon over-melting of polar ice affects the lives of many different animals a reduction of runoff affect the ability to irrigate crops and reduce summer stream flows necessary to keep dams and reservoirs Global warming causes changes in the amount and pattern of precipitation Global warming leads to glacier retreat (co) these changes increase the frequency and intensity of extreme weather events which are destructive, e.g. floods, droughts, heat waves, hurricanes, tornados Global warming causes a rising sea levels (co) these changes lead to an increase in death rates from heatwaves, infectious diseases, allergies, cholera (co) the rising of sea level forces people living in costal city and low-lying Pacific islands to move to other places (co) such population movements often increase nutritional and physical problems and diseases (co) reduction of glacier runoff, in some area such as Norway, the Alps, and the Pacific Northwest of North America, reduces hydropower (co) these changes may lead to failing crops, hence starvation and malnutrition in some regions, especially food insecure population rise in temperature causes serious impacts to the habitats of animals and plant Forest in some regions potentially faces an increased risk of forest fires due to an average increase of temperature	Increasing average temperature and carbon dioxide may have the effect of improving ecosystem’s productivity

increased melting will quickly drain up water rivers in particular region of which water sources of dry season rely upon
For	Against
glaciers lose the ability to retain water on mountains in high precipitation years as snow covering those mountains are seriously depleted due to global warming

over-melting of polar ice affects the lives of many different animals
For	Against
e.g. polar bears have ice as their homes; some freshwater fishes, such as Salmon and Cutthroat trout rely on the cold melt water

(co) these changes increase the frequency and intensity of extreme weather events which are destructive, e.g. floods, droughts, heat waves, hurricanes, tornados
For	Against
	Hurricanes and rising coast associated with weather in general have little to do with global warming

Global warming causes a rising sea levels
For	Against
	Sea levels are not presently rising

(co) reduction of glacier runoff, in some area such as Norway, the Alps, and the Pacific Northwest of North America, reduces hydropower
For	Against
	other forms of power generation can replace hydropower; e.g. solar power

(co) these changes may lead to failing crops, hence starvation and malnutrition in some regions, especially food insecure population
For	Against
	crop production may simply move away from the equator; e.g. more northern Russia and Canada

Increasing average temperature and carbon dioxide may have the effect of improving ecosystem’s productivity
For	Against
Deficient carbon dioxide concentration in the atmosphere causes negative effect to the production of sugar in plants thus hinders their growth	an increase in the total amount of biomass produced is not necessarily good greenhouse effects and warming would continue but there would be no compensatory increase in growth Higher carbon dioxide would only spur growth of plant up to a point, factors like water, nutrients are also essential considerations

an increase in the total amount of biomass produced is not necessarily good
For	Against
biodiversity can still decrease even though a smaller number of species are flourishing

rise in temperature causes serious impacts to the habitats of animals and plant
For	Against
this can lead to the extinction of particular species	species can migrate to cooler climates alteration of habitat is not necessarily a bad thing as a whole to organisms

alteration of habitat is not necessarily a bad thing as a whole to organisms
For	Against
rise in temperature can favor the growth of some other species

Forest in some regions potentially faces an increased risk of forest fires due to an average increase of temperature
For	Against
	there is no evidence supporting a correspondence between forest fire and rise of temperature: jungles in hotter places don't have a higher risk of forest fire This may be due in part to changes in forest management practices

The extensive use of fossil fuels contributes significantly to the global warming
For	Against
(co) Carbon dioxide is one of the major gases which brings about greenhouse effect (methane is a minor greenhouse gas) The combustion of fossil fuels releases carbon dioxide (and methane), increasing the carbon dioxide concentration in the atmosphere The warming is instead primarily a result of variances in solar irradiance	Global warming is not actually occurring

Global warming is not actually occurring
For	Against
The warming is within the range of natural variation

The warming is within the range of natural variation
For	Against
	The annual increase of temperature reaches an unprecedented rating in recent decades

The warming is instead primarily a result of variances in solar irradiance
For	Against
variances in solar irradiance are warming Mars as well	global warming is not connected to cycles of solar activity

variances in solar irradiance are warming Mars as well
For	Against
	Martian warming is caused by changes in it's orbit and axis

fossil fuels can be non-polluting
For	Against
example: pollution caused by coal burning can be removed by filtering

example: pollution caused by coal burning can be removed by filtering
For	Against
	very few coal-fired power stations use filters

the use of fossil fuels is a major source of pollution
For	Against
the combustion of fossil fuel produces large amount of pollutants, e.g. nitrogen oxide, sulphurdioxide, carbon, heavy metals there exists cleaner alternative such as nuclear power, wind power or hydroelectric power

the combustion of fossil fuel produces large amount of pollutants, e.g. nitrogen oxide, sulphurdioxide, carbon, heavy metals
For	Against
	modern technologies can vastly reduce the output of these pollutants; e.g. by filtering

there exists cleaner alternative such as nuclear power, wind power or hydroelectric power
For	Against
	The use of nuclear power is dangerous the uranium needed for nuclear power is running out it is expensive to replace fossil fuel with other energy sources

The use of nuclear power is dangerous
For	Against
	Tens of thousands of people have died drilling for, refining and using petroleum. Far fewer have died from nuclear power generation.

Tens of thousands of people have died drilling for, refining and using petroleum. Far fewer have died from nuclear power generation.
For	Against
	this may be due to less nuclear power being produced: no figure for deaths per kilowatt

it is expensive to replace fossil fuel with other energy sources
For	Against
big sum of money has to invested in developing new technology as well as building new power plants

big sum of money has to invested in developing new technology as well as building new power plants
For	Against
	using other energy source instead of fossil fuel is not expensive in the long run

using other energy source instead of fossil fuel is not expensive in the long run
For	Against
the reserve for fossil fuel is running short, exploration of new energy resources is inevitable in the future money spent in fighting against pollution due to the use of fossil fuel can be saved for new energy resource development

the world economy is based on energy from fossil fuels, so reducing their use would damage the economy
For	Against
	global warming would damage the economy more
