is global warming true or false?

Question

just say true or false and exsplain

Answer 1

It is clearly established:

- that CO2 concentrations increased as a result of human activity

- that CO2 is gas which has a greenhouse potential and increases the radiative forcing

- that the temperature is already starting to increase as a result of the greenhouse effect

* that most people denying global warming here are profiles which are very recent... and disappear shortly after.

CHECK the credentials of any scientist denying anthropogenic (man made) global warming
CHECK every source

Answer 2

The other dude gave a lot of websites. I'm here with my own, but explanations so you don't have to bother going to them.



I actually have SCIENTIFIC DATA to support my claim: Global Warming in the 21st century is a natural phenomenon.



Here is some scientific data I collected over the past few years.

1) 'From 1986 to 2000 central antarctic valleys colled .7 degrees C per decade with serious ecosystem damage from cold' (Antarctic climate cooling and terrestrial ecosystem response, Nature 415, 517-520)

2)the mean temperature in Punta Arenas (closest city to Antarctica) has decreased by roughly .7 degrees C from 1888 to 2004 (giss.nasa.gov)

3) 1940 to 1970, the mean temperature went DOWN while CO2 lvs RISED (giss.nasa.gov)

4) "although it's tempting to blame the ice loss on global warming, researchers think that DEFORESTATION of the mountain's foothills is more likely the culprit" (www.nature.con/nsu/031117/031...

5) hurricane strikes by the decade 1900-2004: the number of hurricanes is going down (www.nhc.noaa.gov/pastdec/shtm...

6) according to the United Nations Intergovernmental Panel on Climate Change, "Examination of meteorological data fails to support the perception [of increased frequencly and severity of extreme climate events] in the context of a long-term climate change"

7) "Overall, there is no evidence that exptreme weather events, or climate variability, has increased, in a global sense, throughought the twentieth century" (IPCC, Climate Change 1995)






Sorry, i have a LOT more, but I just used 30min re-finding these instead of studying for AP calc test tomorrow. Cheers.

Answer 3

We've known for over 100 years that humans have been affecting the climate, it's only in the past few years since it became a political and mainstream issue that some people have been claiming it's false or entirely natural. Such claims are out of synch with the evidence and what scientists have been saying since 1896.

Human induced global warming commenced with the onset of industrialisation approx 200 years ago, natural global warming commenced most recently some 18,000 years ago. Today the human contribution is far in excess of the natural one.

Answer 4

Its very very true. Everyday when the sun comes up the earth gets warmer. Then it cools off at night when the sun goes down ( Global cooling )

Answer 5

Every single scientist actually doing research on it has come to the conclusion that it is real. There is no longer a debate. Those who claim their is a debate are propagandist paid by the energy companies. Read what the real researchers are saying it is real and much of it is not unstoppable regardless of what we do -- just as predicted by computer models back in the 1960s.

Answer 6

Man made global warming is false. Natural global warming is true. The truth is we cant stop it because it is a natural cycle. There are other planets in our solar system warming up also.

Answer 7

global warming might happen in 50 million ye but it happens because the ozone layer is breaking apart making holes or gaps in the layer and if the whole layer breaks apart the it might hit 2,000 degrees farenhiet!!!!!

Answer 8

Well...the sun is getting hotter and a lot of hurricanes are happening throughout the world even my mom's birth place which is in China

Answer 9

Global Warming is false. However, global climate change is happening. There is nothing that you can to to prevent it. Watch The Great Global Warming Swindle.

Answer 10

its true
who or what is the cause is in question.
some say it is only the world
but the evidence suggests that humans are responsible for a part of it
how great a part is the big controversy
Humans have big problems with taking the blame

any blame
Truth hurts
