Global Warming Exists
Debate Rounds (3)
First, is global warming actually happening?
According to NASA, the average temperature has raised by 1.4 degrees Fahrenheit since 1880.
According to the United Nations, the past two decades have been the hottest in more than 400 years.
Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.
Glaciers and mountain snows are rapidly melting"for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.
An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.
Second, are humans causing global warming?
The report, based on the work of some 2,500 scientists in more than 130 countries, concluded that humans have caused all or most of the current planetary warming. Human-caused global warming is often called anthropogenic climate change.
Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
Third, what is likely to occur in the future?
Sea level could rise between 7 and 23 inches by century's end. Rises of just 4 inches could flood many South Seas islands and swamp large parts of Southeast Asia.
Some hundred million people live within 3 feet of average sea level, and much of the world's population is concentrated in vulnerable coastal cities. In the U.S., Louisiana and Florida are especially at risk.
Glaciers around the world could melt, causing sea levels to rise while creating water shortages in regions dependent on runoff for fresh water.
Strong hurricanes, droughts, heat waves, wildfires, and other natural disasters may become commonplace in many parts of the world. The growth of deserts may also cause food shortages in many places.

Reasons for voting decision: Conduct was for the forfeit. Pro's contention were on a bunch of topics namely increase in temperature, sea level and the scientific consensus surrounding global warming. All Con did was to ask one question about 'people may be wrong' instead of addressing the issue one by one. Pro then refutes Con's proposed arguments but Con however did not refute PRO multiple contentions whatsoever, So arguments to Pro for the dropped arguments.
