This debate is about Global warming existence,16kadams is arguing that global warming doesn't Exist and I to prove its Existence.
Here are some parameters.
1.The bird is the Word.
2.All sources must be posted.
3.No theories,ONLY FACTS.
4.Circular logic may be used.
5.The opponent must not contradict themselves.

Round 1:Acceptance and First arguments.
Round 2:Other arguments and proof.
Round 3:Rebuttals
Round 4:Closing arguments and statements.
Voters are Recommended to choose wisely.



Opening arguments are allowed in r1 according to the layout, I accept this debate btw (duh).

C1: No warming in the last decade and more!

Now for global warming to be real, we must currently (or in the last decade) be seeing a large increase in global temperatures as well as other local anomalies. These anomalies include melting glaciers and icecaps. Before weget into that, lets ask is the current warming really warming?

From 2003 -2007, although there are basic ups and downs in temperature, we see there is an overall downward trend. That's a downward trend of 7 years! (for those who believe in man made global warming, note this cooling/flat line was the same time CO2 is emitted. Now this cooling trend is significant as IPCC data cannot explain this and fails in their predictions. A few facts: If we assume the greenhouse theory is correct, it is still dependent on the suns heat getting here to be trapped. If we assume it is false, then well its false. Either way it supports my next claim. Solar activity is declining. Magnetic convection currents are declining, fast. in 2008 there where 266 days with no sun spots. And global temperatures are falling at a rate of 6 degrees per century if the current trends continue. "If that cooling were to persist, there would be an Ice Age by 2100. Scafetta & West (2008) conclude that the Sun caused 69% of the global warming that ceased in 1998."[1]

Now we must also point out many emails, a scandal now known as climategate (its clever lol) reveals this sentence: "The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't."[2]

Yes, they deleted and hid this information as they cant justify scientifically this cooling/flat line! "Given the widely noted increase in the warming effects of rising greenhouse gas concentrations, it has been unclear why global surface temperatures did not rise between 1998 and 2008."[3] (Kaufmann et al 2011 paper)

"Recently US meteorologist Anthony Watts showed that the continental U.S. has not warmed in the last 10 years, and in fact has grown cooler in the summer and colder in the winter. The climate data numbers come from the National Climatic Data Center. ... Regionally 7 of the 11 regions reported by Environment Canada showed declining or flat winter temperature departures over the last 10 years. ... The Northern Hemisphere, North Atlantic, North Pacific and East Pacific SST Anomalies are all dropping."[4]

Graphs to sum up:

I will argue more on this later if needed.

C2: Ice caps melting?

For there to be overall melting, there needs to be large portions of the artic to melt. As heating means oceans heat, artic melts, and overall tempertures rise. Now looking into glaciers, many of them are in the alps and himalayas. Now a study confirmes my thoughts/predictions since last year, the himalayas lost no ice. Although the lower areas are melting, the peaks are gaining ice so its a 50-50 measurment. [5]

Lets quote for a while:

"ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap."[6]

"A report from the US National Snow and Ice Data Center in Colorado finds that Arctic summer sea ice has increased by 409,000 square miles, or 26 per cent, since 2007."[7]

"Though the ice may be melting around the edges of the Greenland Icecap in recent years during the warm mode of the AMO much as it did during the last warm phase in the 1930s to 1950s, snow and ice levels continue to rise in most of the interior. Johannessen in 2005 estimated an annual net increase of ice by 2 inches a year."[8]

Ice caps not melting.


Global warming? Not currently. The earth is cooling and is expected to keep cooling. [1] VOTE CON

Sorry be i'm really considering conceding due to small Time frame i have to do this,but i'll give it a shot.

C1: CO2 emissions

Wolrdwide Co2 have increased 26% from 1990 to 2005,that a extra 10,000! tons of Co2,

"In 2008, U.S. greenhouse gas emissions totaled 6,957 million metric tons of carbon
dioxide equivalents, a 14 percent increase from 1990"

"During the period from 1990 to 2008 (see Figure 1):
o Emissions of carbon dioxide, the primary greenhouse gas emitted by human
activities, increased by 16 percent.
o Emissions of fluorinated compounds, released as a result of commercial,
industrial, and household uses, rose by 66 percent. Although fluorinated gases
accounted for only 2 percent of all greenhouse gas emissions in 2008, they are
important because they have extremely high global warming potential values and
long atmospheric lifetimes.
o Methane emissions decreased by 7 percent, largely because of reduced emissions
from landfills and coal mines.5
o Nitrous oxide emissions, largely derived from agricultural soil management,
nitrogen application, and vehicle emissions, declined by 1 percent.
• Electricity generation has accounted for about 32 percent of total U.S. greenhouse
gas emissions since 1990. Transportation is the second largest source of greenhouse
gas emissions, accounting for 27 percent of emissions since 1990 (see Figure 2).
• In 2008, 14 percent of U.S. greenhouse gas emissions were offset by uptake of
carbon and “sequestration” in forests, trees, agricultural soils, and landfilled yard
trimmings and food scraps (these are referred to as sinks, as shown in Figure 2
beneath the axis).
• Emissions per capita have remained nearly level since 1990 (see Figure 3), as emissions
have increased at about the same rate as the population"All this from the Epa(yes i'm using this for my main source) Could they be Lying?But Why?

C2:Climate Change

The climate is changing the U.S and other places around the world, Not going down but increasing by 2-5 degrees Farinheit each year.The heat outside is getting hotter and hotter.And it's not the Sun its the depletion of the Ozone Layer and the Increase in Co2.Still not conviced? Well I've got something for you.Over the past years .......................... Forget it I don't have enough time for this i have about 8 finals to study for.



C1: CO2

My opponents argument proves NOTHING. It has nothing about warming trends, just argues CO2 is rising. This is likely an appeal to the greenhouse theory, but fails for a few reasons:

1.) According to climate models and the greenhouse theory, if we increase CO2 the higher atmospheres should heat up faster then the ground temperatures. The problem is using air baloon data, they found the atmosphere had no/little heating. [1] This already refutes the fact global warming has an impact.

2.) There is little correlation it is even causing the warming! There is not even a century of data supporting the point! In 1940-70s we saw a decrease in temperatures, 1914-78 all decrease. Almost 4 decades. Why is this important? At the same time the economy was booming and CO2 was raising. According to greenhouse theory, it would be rising consistently. It was not. Before 1940 was when most of the warming occurred, also a time of little CO2 and depression lead to lower industry emissions. THERE IS NO CORRELATION. My opponents argument may work if there was correlation, but there is NOT.

3.) There is no historical correlation, if there where natural increases in the past there would also have to be natural increases due to CO2. Few problems. First, historically CO2 came AFTER the warming by about 800 years. [2] "To establish a causal relationship it must be demonstrated that the presumed cause precedes the presumed effect. [...] In thus considering the seven greatest temperature transitions of the past half-million years - three glacial terminations and four glacial inceptions - we note that increases and decreases in atmospheric CO2 concentration not only did not precede the changes in air temperature, they followed them, and by hundreds to thousands of years!"[3]

Yes, ~800-1000 years wait period. Also there is no correlation even with the precede/follow effect. To make it easier to understand my sentence here is this:

Source is printed on the graph.

Further the cycle is predictable (Not through CO2 as shown) but by natural factors. As this 1990 IPCC graph shows:

As we can predict, our temperture will fall as we are flatlining. In the medivial period, they flatlined then fell. It is predictable through natural factors, and not co2, hence the argunment fails for reasons above. And cooling/flatline is predicted.

C2: Climate change

No proof was brought of this data, no source no anything. As there is no proof behind this, just assumption, I will quote to refute:
"According to Dr. Roy Spencer, climatologist and former NASA scientist, satellite data for June shows that global temperatures are falling. The Earth has cooled an astounding .74°F since former Vice President Al Gore released his propaganda piece "An Inconvenient Truth" in 2006."[4]
