The greenhouse gases absorb the infrared radiation from the sun, and further on send radiation back to the planet's surface. The greenhouse gases are essential for life on earth, however they become a problem when humans emit excessive greenhouse gasses, like carbon dioxide, through using fossil fuels. With excessive greenhouse gases in the atmosphere, more of the sun's warmth will be trapped, which will lead to global warming.]]> 2016-10-28 12:33:38 UTC https://padlet.com/andreasnygard/climatechange/wish/133866767 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/133866869 2016-10-28 12:34:02 UTC https://padlet.com/andreasnygard/climatechange/wish/133866869 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/133867332 Large scale volcanic eruptions are known for having a powerful impact on our climate.

The amount of absorbed and reflected sunlight depends on the Earth's atmosphere and surface; light-colored surfaces like snow and clouds reflect more sunlight, where as oceans and forests absorb it instead. This amount of absorbed and reflected sunlight is referred to as "albedo".]]> 2016-10-28 12:55:42 UTC https://padlet.com/andreasnygard/climatechange/wish/133872568 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/133875086 2016-10-28 13:03:54 UTC https://padlet.com/andreasnygard/climatechange/wish/133875086 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/133875215 Below are the consequences that follow climate change, whether they are man-made or natural]]> 2016-10-28 13:04:18 UTC https://padlet.com/andreasnygard/climatechange/wish/133875215 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/133875829 One consequences of climate change is higher temperatures, which lead to more extreme weather. with the global warming, stronger storms, more draught, heavier downpours and more frequent heatwaves are expected. ]]> 2016-10-28 13:06:02 UTC https://padlet.com/andreasnygard/climatechange/wish/133875829 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/133876154 Our global economic system is dependant on clean water, fresh air and a stable climate.

Our rainforests will suffer from high levels of extinction, and as trees begin to wither due to rising temperatures, CO2 emissions will increase, resulting in a runaway greenhouse effect.]]> 2016-10-28 13:14:43 UTC https://padlet.com/andreasnygard/climatechange/wish/133878325 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/133879165 Because of the big climate changes some parts of the world, like the antarctic,  will experience, many species are endangered.

Because of earth's natural amount of CO2 in it's atmosphere, som of the reflected light is trapped by said CO2 which prevents it from escaping into space and thus warms the planet further. Pro-climate change activists claim that since 1751, 337 billion metric tons of CO2 has been released into the atmosphere as part of fossil fuel burning. They argue that the atmospheric CO2-levels have risen from the preindustrial 280 ppm (parts per million) to 400 in 2013. 

On the other hand, skeptics argue that the temperature fluctuation we see today is natural, since the earth's climate has always warmed and cooled. A study from 2003 by the Harvard-Smithsonian center for Astrophysics found that "many records reveal that the 20th century is probably not the warmest nor a uniquely extreme climatic period of the last millennium."]]> 2016-11-01 07:48:15 UTC https://padlet.com/andreasnygard/climatechange/wish/134399277 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/134399666 The Anderegg study from 2010 found that 97%-98% of climate researchers believed climate change was real. The cook review of 2013 found that only 78 studies (0.7%) rejected that climate change is man made. However, more than a thousand climate scientists do not believe that human activity is the primary source of the climate change. Amongst those scientist are several former UN IPPC scientists. ]]> 2016-11-01 07:50:49 UTC https://padlet.com/andreasnygard/climatechange/wish/134399666 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/134402824 The rise of atmospheric levels of co2 must be man made because the rise in co2 levels occurred in a faster rate than natural climate change is able to produce. The atmospheric level of co2 did not surpass 300ppm in the last 650 000 years. This changed in the mid 1900's. The level of co2 has risen from 317ppm in 1958 to 400ppm in 2013. However, the earth's climate record can show that global warming has preceded a rise in co2. Former director of Greenpeace, Patric Moore said; " there is some correlation, but little evidence to support a direct casual relationship between co2 and global temperature through the millennia". ]]> 2016-11-01 08:18:08 UTC https://padlet.com/andreasnygard/climatechange/wish/134402824 andreasnygard https://padlet.com/andreasnygard/climatechange/wish/134405476 Those who believe climate change is man made ]]> 2016-11-01 08:43:57 UTC https://padlet.com/andreasnygard/climatechange/wish/134405476 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/135308310 The global temperatures has been rising in a much faster rate than natural climate changes are able to cause. the natural climate changes are unable to cause such a big change in temperature on their own, thus human activity must contribute to these changes. According to William Happer, professor at Princeton university, additional co2 emissions will not affect the average global temperature. That is because there is already so much co2 in the atmosphere, and the co2 has blocked most of the infrared radiation possible.]]> 2016-11-04 09:14:28 UTC https://padlet.com/andreasnygard/climatechange/wish/135308310 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/135312745 2016-11-04 09:41:18 UTC https://padlet.com/andreasnygard/climatechange/wish/135312745 nataliehenriksencreed https://padlet.com/andreasnygard/climatechange/wish/135313098 Hillary Clinton things climate change si an urgent threat which may implement that she takes the environmental issues very seriously.
