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 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 hurricanes?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:There has been an increase in hurricane intensity in the North Atlantic since the 1970s, and that increase correlates with increases in sea surface temperature.The observed increase in hurricane intensity is larger than climate models predict for the sea surface temperature changes we have experienced.There is no clear trend in the number of hurricanes.Other regions appear to have experienced increased hurricane intensity as well, but there are concerns about the quality of data in these other regions.It is more likely than not (>50%) that there has been some human contribution to the increases in hurricane intensity.It is likely (>66%) that we will see increases in hurricane intensity during the 21st century.
What does the Fourth Report of the IPCC say about the global temperature and sea level rise?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Global Temperature: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).Sea Level Rise: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.

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 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 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 does the Fourth Report of the IPCC say about projections for the future?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Climate:It is very likely that there will be an increase in frequency of warm spells, heat waves and events of heavy rainfall.It is likely that there will be an increase in areas affected by droughts, intensity of tropical cyclones (which include hurricanes andtyphoons) and the occurrence of extreme high tides.Temperature:Surface air warming in the 21st century:Best low estimate is 1.8 °C (3.2 °F)Best high estimate is 4.0 °C (7.2 °F)Sea Levels:Best low estimate is 18 to 38 cm (7 to 15 inches)Best high estimate is 26 to 59 cm (10 to 23 inches)(The report warns that the sea level estimates may be too low, as the modelling took no account of ice-sheet melting.)

How do you say fourth period?
you say, fourth period!! hahah!!!
What does the 2011 Arctic Monitoring and Assessment program say about rising sea levels?
In its 2011 report the Arctic Monitoring and Assessment Program (AMAP), based in Norway, found that the Greenland ice sheet is melting four times as fast as it was ten years ago. "Sea levels will rise higher and faster than the United Nations predicted just four years ago." "The past six years have been the warmest period ever recorded in the Arctic." The report states that sea levels are projected to rise by 0.9 meters to 1.6 meters by 2100, and that "the loss of ice from Arctic glaciers, ice caps and the Greenland ice sheet will make a substantial contribution". (In 2007 the IPCC put the projected rise at 59 centimeters by 2100) The report goes on to say that each centimeter of sea level rise translates into one meter of beach erosion, meaning that the coastlines will move about 160 meters further inland.
