Global Warming is assumed by leading experts in climate science to be caused by “Greenhouse Effect”. The Greenhouse effect is when particular gases such as water vapour (H20) a gas that acts as a feedback to the climate, it increases as the Earth warms. Nitrous Oxide(N2O) a gas that can be produced by the use of organic and commercial …show more content…
Whilst other scientists have speculated that it is purely humans increase in CO2 concentration through such activities as burning fossil fuels. Livescience.com have reported the increase of temperature present in planet earth is not an exclusive characteristic, there have been numerous studies to show that other planets such as Mars and Pluto have had a dramatic rise in base temperature. This leads scientists to believe that it is not the greenhouse effect that has heated the Earth 's surface, but rather the contribution of heat from the sun. Scientists argue that the sun can be blamed for up to 30 per cent of the Earth 's warming- a study from Columbia university backs this evidence up. In a 75 year study scientists detected no sunspot activity. This study coincided with a ‘mini ice age’. This was called the “Maunder Minimum” and was founded during the coldest part of this ice age, which affected Europe and North America for the most part of 350 years. This study is to be thought to correlate with the increase in solar brightness and could contribute to the Earth’s slow build up to global warming. Around 1990 scientists started to notice the suns increase of heat that reached earth after years of the sun not contributing to any known global warming, the sudden reverse is still being studied, explaining why it is acceptable for scientists who do believe in anthropogenic climate change to argue their
