In this section you may speak about anything in any way you
like.
If you have no idea of what to say, answer one of these questions
or have a look at the relevant links at the bottom of the list. (Most of these questions were borrowed from those pages.)
What is global warming?
What is global warming?
What is climate change? Is the climate warming?
What is the greenhouse effect, and is it affecting our climate?
Are greenhouse gases increasing?
How does the presence of carbon dioxide and other greenhouse
gases in the atmosphere behave like a greenhouse?
What do greenhouse gases do?
What are the sources of gases that are also considered “greenhouse”
gases? How significant are their effects?
Do man-made greenhouse gases matter compared to water vapor?
What is an “El Niño?” Are El Niños related to
Global Warming?
Is the hydrological cycle (evaporation and precipitation) changing?
Is the atmospheric / oceanic circulation changing?
Is the climate becoming more variable or extreme?
How important are these changes in a longer-term context?
Is the sea level rising?
What is the combustion reaction? What is the important by-product
of this reaction that is important for this issue? How much
carbon dioxide is being produced by various energy producing
reactions?
What is the evidence that temperature and carbon dioxide concentrations
are correlated? What do the ice core samples tell us about
past climates?
How good is the temperature data that is being used to support
the theory of global warming? Can this data be used as an absolute
proven fact that global warming is already occurring or will
occur?
Has the Sun been more active in recent years, and could it be
responsible for some global warming?
Can the observed changes be explained by natural variability,
including changes in solar output?
Haven’t satellites actually observed cooling temperatures in
the lower atmosphere?
Are the ozone hole and global warming related?
Are the unusual or extreme weather events in my area caused
by global warming?
Are there natural processes that will amplify or limit global
warming?
Is global warming connected to the hole in the ozone layer?
History
Has the climate changed during the 20th and 21st century? What
is and is not known with certainty about climate change? Is
global warming already happening?
If the Earth has warmed and cooled throughout history, what
makes scientists think that humans are causing global warming
now?
Causes
What is the evidence that global temperatures are increasing?
Or can we really not tell? Are recent extreme weather events
due to global warming?
What causes this climate change? What is causing global warming?
What does the greenhouse effect have to do with global warming?
Are humans contributing to global warming?
What is the evidence that the use of fossil fuels, which produce
carbon dioxide, is causing climate change? How much carbon dioxide
is being produced by various energy producing reactions?
What technologies are used to provide energy in a modern society?
What types of fuels are used for these energy sources? How much
carbon dioxide is being produced by various energy producing
reactions?
Are fossil fuels being used excessively in the industrialized
countries to provide for the convenience of society? Should
people pay more for fuels or do they have a "right"
to cheap gasoline?
What is the cause of sea level rise? How many inches has the
sea level risen so far?
Consequences
if Global Warming actually exists
What about the future?
How much warmer is the Earth likely to become? How many degrees
is global warming expected to raise temperatures?
Would a temperature rise of a couple of degrees really change
the global climate?
Do extreme events such as heat waves and floods have anything
to do with global warming?
What climate changes are expected for the future? How could
climate change affect us in the future?
What are some of the consequences or impacts to the environment
should global warming occur? What are the likely consequences
of climate change to ecosystems? Can ecosystems adapt to Climate
Change?
What are some of the consequences or impacts to human society
should global warming occur? What are the likely consequences
of climate change to human societies?
What if global warming isn’t as severe as predicted?
Why is global warming a problem?
Adaptation, prevention or cure - Political and economic obstacles
How long does carbon dioxide remain in the atmosphere?
Where are we heading with atmospheric carbon dioxide?
How much in carbon emissions does the U.S produce?
How do you get 20 pounds of CO2 out of a gallon of gasoline
that weighs about 6 pounds?
If we stabilized greenhouse gas emissions at today’s rates,
would global warming stop?
If we immediately stopped emitting greenhouse gases, would
global warming stop?
What can we do about global warming? Is there anything we can
do about global warming?
Can societies adapt to Climate Change?
How could greenhouse gas emissions be reduced?
What are the economic ramifications of a reduction in carbon
dioxide emissions mandate? Is it possible to switch over to
"clean" technologies while still using fossil fuels?
Can alternative energies realistically be brought on line fast
enough that the use of fossil fuels would be discouraged?
Will responding to global warming be harmful to our economy?
As currently proposed in the agreement in Kyoto, Japan, December
1997, the industrialized nations committed to reducing carbon
dioxide emissions, while the undeveloped nations such as China,
India, and others did not commit to any reductions. Is this
correct and fair?

Should the U.S. Senate ratify the Kyoto Treaty and agree
to quantified legally-binding objectives for greenhouse gas
emission limitations and significant overall reductions within
specified timeframes?
Should people be charged a tax to more accurately reflect the
damage done to the environment by the use of excessive energy?
In other words should taxes be brought to a level where gasoline
costs $3-4 per gallon as they are in Europe to discourage gas
guzzling cars and SUV's?
