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 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 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 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.

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 we say good afternoon in Antarctic?

There is no Antarctic language. One would say 'good afternoon' generally, and have it acknowledged as an afternoon greeting.
