The United Nations' Intergovernmental Panel on Climate Change (IPCC)'s scientific consensus is that global warming is being caused by anthropogenic means, that it, it is caused by man's actions, especially those that add to the greenhouse gases in the atmosphere. Man does this by the burning of fossil fuels (coal, oil and natural gas) and by deforestation.Combustion of fossil fuels releases long-stored carbon dioxide into the atmosphere, and deforestation has removed the carbon sinks of the great forests that used to absorb and store carbon.

Do all scientists believe there is a link between human activity and global warming?
As with all issues, not ALL scientists believe in the link between human activity and global warming. However, the majority of scientists feel that the evidence for global warming is adequate to prove its existence. The majority of scientists who reaffirm the theory of global warming believe there is a link between climate and human activity. According to the Union of Concerned Scientists, "The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) states: it is a greater than a 90 percent certainty that emissions of heat-trapping gases from human activities have caused "most of the observed increase in globally averaged temperatures since the mid-20th century." "
What was alarming about the 1990s in regards to global warming?
In the 1990s, there was growing scientific consensus on the impact of human activities on global warming, and evidence showed that greenhouse gas emissions were contributing to rising global temperatures. This raised concerns about the long-term effects of climate change, such as sea level rise, extreme weather events, and threats to ecosystems and biodiversity. The urgency to address global warming and its potential consequences became increasingly alarming during this time.
What are the world leaders doing about global warming?
The UN has established the InterGovernmental Panel on Climate Change (IPCC) to gather and share information about global warming. The Kyoto Protocol is an agreement that all countries signed to limit their emissions of greenhouse gases.
What is the relationship between halocarbons and climate change?
Halocarbons are synthetic chemicals that contribute to ozone depletion and also have a greenhouse effect, trapping heat in the atmosphere and contributing to climate change. They are potent greenhouse gases that can have a significant impact on global warming potential. Regulations have been put in place to phase out the use of certain halocarbons to mitigate their impact on both ozone depletion and climate change.
What is IPCC in relation to global warming?
IPCC stands for the United Nations' Intergovernmental Panel on Climate Change.The Intergovernmental Panel on Climate Change (IPCC) is an organization set up by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988. Its aims are to assess the impacts of human-induced climate change and report the impacts and possible adaptation and mitigation.The IPCC, which is made up of many scientists (152) who are in the climate-related fields, and who perform their work on a voluntary basis, does not conduct any research itself. It makes periodical assessments based on all the available information, i.e., mostly peer-reviewed, scientific studies, papers and research published to that date by world-wide scientists in the climate-related fields (e.g., climatologists, biologists, paleo-climatologists, oceanographers, physicists, etc.).The latest IPCC assessment, from 2007 (sometimes referred to as the Fourth Assessment), was written by 620 authors and editors from 40 countries. The Panel's next assessment is due in 2014.
What has the IPCC got to say about global warming?
The InterGovernmental Panel on Climate Change (IPCC) states that global warming is happening, and that it is being caused by the human activities of deforestation and the burning of fossil fuels. Deforestation means that removed trees can no longer remove carbon dioxide from the atmosphere. Burning of fossil fuels releases carbon dioxide into the atmosphere that has been long hidden underground.
What pressure groups are stating the dangers of global warming?
Lots of groups are starting to speak out about the dangers of global warming, including the government, the NRDC (Natural Resource Defense Council), IPCC (Intergoverment Panel on Climate Change), and the WWF (World Wildlife Fund).
Where can you find a record of the changes from global warming?
Records of changes from global warming can be found in scientific reports, studies, and data collected by organizations like the Intergovernmental Panel on Climate Change (IPCC), NASA, NOAA, and other research institutions. These records include temperature measurements, sea level rise, ice melt, and changes in ecosystems that provide evidence of the impacts of global warming.

What are the findings of the ipcc?
The Intergovernmental Panel on Climate Change (IPCC) finds that human activities are the primary driver of global warming, leading to unprecedented levels of greenhouse gases in the atmosphere. The IPCC also warns that urgent action is needed to reduce emissions and limit the impacts of climate change such as rising temperatures, sea level rise, and extreme weather events.

What do you understand by global warming?
Global warming is the way the Earth is getting warmer. The word 'global' means 'worldwide' and the warming is of the atmosphere, the oceans and the surface of the earth. According to the Intergovernmental Panel on Climate Change (IPCC), temperatures, averaged over all land and ocean surfaces, have warmed roughly 1.33°F (0.74ºC) over the last century, (see page 2 of the IPCC's Climate Change 2007: Synthesis Report Summary for Policymakers Link below.). More than half of this warming, about 0.72°F (0.4°C), has occurred since 1979.
What does the Fourth Report of the IPCC say about the warming of the planet?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Cold days, cold nights, and frost events have become less frequent. Hot days, hot nights, and heat waves have become more frequent.Eleven of the twelve years in the period (1995-2006) rank among the top 12 warmest years in the instrumental record (since 1880).
What are the world leaders doing about global warming?
The UN has established the InterGovernmental Panel on Climate Change (IPCC) to gather and share information about global warming. The Kyoto Protocol is an agreement that all countries signed to limit their emissions of greenhouse gases.
What do people think is making polar ice caps melt?
because of the effect of global warming. the temperature of the earth increases therefore melts the polar caps. The Arctic has seen some ice loss, although we have also seen record growth as of late. The Antarctic is still growing in terms of ice and according to the IPCC report, it is expected to keep doing so for many decades to come.

People that believe in global warming?
Have the very slimmest of Hope. That Hope depends, ironically, upon technology. We have lots of Technology so let us Hope and work towards the Day when Technology may undo what technology has done.
