∙ 11y ago
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).

Where can you find a record of the changes from global warming?
There is a basic quiz on global warming at the link below.
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 average Northern Hemisphere temperatures?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1300 years (including both theMedieval Warm Period and the Little Ice Age).
What is global warming and how does styrofoam contribute to global warming?
Global warming, according to the United Nations through the IPCC (Intergovernmental Panel on Climate Change) means that the earth is gradually warming because of actions of the human race. Specifically by adding to the greenhouse gases in the atmosphere, and cutting down the world's forests. When we burn coal and oil, which we do to produce electricity and drive our transport, we release carbon dioxide that has been hidden away for millions of years. This is warming the planet. The second part of the question is related to this. Styrofoam (polystyrene) is a plastic. Plastics are made from oil, mostly fossil fuel oil. Styrofoam is usually made with hydrochlorofluorocarbons (HCFC) as blowing agents. These affect ozone depletion and global warming. They are not as harmful to the ozone layer as chlorofluorocarbons (CFC) which were formerly used, but as a greenhouse gas HCFCs are about 1000 times more powerful than carbon dioxide.
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.
What does the Fourth Report of the IPCC say about levels of methane in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of methane in the atmosphere in 2005 (1774 ppb) exceeds by far the natural range of the last 650,000 years (320 to 790 ppb).
What does the Fourth Report of the IPCC say about levels of carbon dioxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of carbon dioxide in the atmosphere in 2005 (379 ppm) exceeds by far the natural range of the last 650,000 years (180 to 300 ppm).
What does the Fourth Report of the IPCC say about levels of nitrous oxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Nitrous oxide concentrations have risen from a pre-industrial value of 270 ppb to a 2005 value of 319 ppb. More than a third of this rise is due to human activity , primarily agriculture.
What does the Fourth Report of the IPCC recommend for Waste and Garbage?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, recommends:Commercial Technologies currently available:Landfill methane recovery;waste incineration with energy recovery;composting of organic waste;controlled waste water treatment;recycling and waste minimizationCommercial Technologies projected by 2030:Biocovers and biofilters to optimize the oxidation of methane (CH4).

What does the Fourth Report of the IPCC say about levels of carbon dioxide methane and nitrous oxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:"Carbon dioxide, methane, and nitrous oxide are all long-lived greenhouse gases.andCarbon dioxide, methane, and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values."
What does the Fourth Report of the IPCC say about the Arctic?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:"Average Arctic temperatures increased at almost twice the global average rate in the past 100 years.""Sea-ice is projected to shrink in both the Arctic and Antarctic … In some projections, Arctic late-summer sea ice disappears almost entirely by the latter part of the 21st century."

What does the Fourth Report of the IPCC say about the Antarctic?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Antarctic sea ice shows no significant overall trend, consistent with a lack of warming in that region.Losses from the land-based ice sheets of Greenland and Antarctica have very likely (>90%) contributed to sea level rise between 1993 and 2003.Climate change has resulted in changes in some Arctic and Antarctic ecosystems."Sea ice is projected to shrink in both the Arctic and Antarctic … In some projections, Arctic late-summer sea ice disappears almost entirely by the latter part of the 21st century."
What does the Fourth Report of the IPCC say about sea levels?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Losses from the land-based ice-sheets of Greenland and Antarctica have very likely (>90%) contributed to sea level rise between 1993 and 2003.Ocean warming causes seawater to expand, which contributes to sea level rising.Sea level rose at an average rate of about 1.8 mm/year during the years 1961-2003. The rise in sea level during 1993-2003 was at an average rate of 3.1 mm/year. It is not clear whether this is a long-term trend or just variability.
What does the Fourth Report of the IPCC say about average Northern Hemisphere temperatures?

What was alarming about the 1990s in regards to global warming?
The first two reports (1990 and 1995) of the International Panel on Climate Change (IPCC) confirmed that the world is definitely warming and this warming is being caused by human activity.
