What is climate change? - Met Office climate change guide, time: 4:35


A wide range of other observations (such as reduced Arctic sea ice extent and increased ocean heat content) and indications from the natural world (such as poleward shifts of temperature-sensitive species of fish, mammals, insects, etc.) together provide incontrovertible evidence of planetary-scale warming. Debates on the Causes of Global Warming. IPCC holds that today's global warming is mainly due to anthropogenic activities rather than natural variability, which is emphasized by NIPCC. The surface temperature observations since the midth century support the hypothesis of anthropogenic impact, but for the last one hundred years or so. Forest Fires: Deforestation by nature is another leading cause of global warming. Natural forest fires are usually televised on the news, showing the devastation of mountain homes and communities. While this loss is tragic, the effects of these natural occurring forest fires pose a problem for the earth’s air. Natural Causes of Climate Change-Plate Tectonics -Volcanic Activity-Variations in the Earth’s orbit-Solar variability * All theories can explain some portion of climate variability, but no one theory can explain all of the observed changes. However, to conclude the rise of global temperature is caused by the recent increase in greenhouse gases is more difficult, since the greenhouse gases are not the only factors affecting Earth’s climate. External but natu- ral factors such as volcanoes and changes in solar irradi- ance also alter global .Changes in the Earth s climate, due to human activities i also known as anthropogenic climate change, or natural processes that are already occurring or . 2 How do scientists know that recent climate change is largely caused by human 3 CO2 is already in the atmosphere naturally, so why are emissions from.

"Global warming is important because it is so persistent and global in scale, the causes of global warming is the first step to curbing its effects. Some argue that the recent global warming is due to natural fluctuations and not to human activities. This argument In the case of global warming, the question is: What is causing the increase in .
