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 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).


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.


How credible is the IPCC?

They have flip flopped and been caught lying on many issues. The hockey stick graph was the focal point of the first report. It was discovered that the data was just not factual. They made no retraction. Climategate proved that many of the leading experts were lying about data. No retraction was made. The IPCC has very few actual scientists and even fewer climate experts in their working group. The leader is an Economist. Of the 3000 people involved, only fewer than 60 are involved with science at all. There models ignore and negative feed backs of water vapor and have managed to be unable to reproduce the past. (An essential element of the models ability to reliably predict the future). They place 90% realiability on models that are 60% accurate. There projections have continuously been far more extreme when compared with the real weather patterns. They claimed we should see an increase in the size and scope of hurricanes. Level 5 hurricanes are currently lower in number and NASA claims we are seeing a 30 year low in storms. Arctic is is predicted to melt. Since 2007 Arctic summer ice has grown by 26%. The 2007 report claimed a sea level rise of 3 to 5 mm. Less than 1 mm has been seen. Would you trust a group that has no background in the subject and been wrong every time they suggested an event? The IPCC has also been involved in other scandals including: Himalaya-Gate - Alarmist report by the IPCC that the Himalyan glacier will have melted by 2035. As it transpired the report was without any scientific basis. Amazon-Gate - The IPCC claimed that up to 40% of the rain forests in the Amazon were at risk from global warming and would likely be replaced by "tropical savannas" if temperatures continued to rise. The scientific-looking report, on which this claim was based, was a non-peer reviewed article for the WWF, by an Australian policy analyst and a freelance journalist for the Guardian newspaper (not even experts let alone scientists!). But the biggest scandal to date is the IPCC's claim, made in 1995, that it had found "a "discernible human influence" on the earth's changing climate. The claim was inserted by the report's lead author, Ben Santer of the Lawrence Livermore government laboratory, after the IPCC's consulting scientists had agreed a draft that specifically said no such "human fingerprint" had been found. Due to this deliberate reversal of the report's findings, Santer also altered the trajectory of every IPCC document since. He argued that the alteration that it was justified based on two of his own studies, which "cherry-picked" the earth's temperature record from 1963-1987, deliberately ignoring temperatures that didn't confirm the Greenhouse theory. Thus the "discernible human influence" as claimed by the IPCC remains without scientific support to this day.

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.
