Who wants to bet that the global warming and climate change gaggle that blames mankind for the warming, if they even bother to read these reports will say the IPCC was bought off by *THEM*
[IPCC Draft report echoes Climate Depot's Extreme Weather Report]: 'No significant observed trends in global tropical cyclone frequency...does not support AR4 conclusions regarding global increasing trends in droughts...low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale...there is currently no clear and widespread evidence for observed changes in flooding'
Debunking the persistent myth that global warming stopped in 1998
"The latest climate change denial claim ahead of the release of the Intergovernmental Panel on Climate Change assessment report is that global warming stopped in 1998. A slowing in the observed rate of global warming has prompted dubious suggestions that temperatures have not increased significantly in the past 15 years.
It's true that after rising rapidly in the 1990s, global average temperature increases at the earth's surface have slowed since 1998. But warming hasn't stopped.
The last decade was the hottest on record globally. Each year from 2000 to 2010, except 2008, was in the 10 warmest recorded globally.
What's most concerning is that it should be considerably cooler than average, not hotter. Since 1997, several natural climate factors have aligned that should have produced a discernible cooling effect on global temperatures.
A lull in solar activity from 2005 to 2010, combined with two very strong La Niña episodes from 2010 to 2012, would be expected to produce a strong decrease in global temperatures.
Yet the world hasn't cooled. On the contrary, global surface temperatures are moving in the opposite direction to natural climate variations, due to greenhouse gas warming.
To understand recent changes in the rate of heating, we need to look beyond surface temperatures. Warming at the earth's surface is a narrow measure of climatic change, with only a fraction of greenhouse gas warming heating the two meters above the ground encompassed by surface thermometers. Ocean heat content provides a more comprehensive measure of global warming, because the oceans are vast heat reservoirs. The oceans absorb about 93 per cent of the additional heat trapped in the atmosphere by greenhouse gases such as carbon dioxide.
Recent studies show that natural cooling in the Pacific Ocean has counteracted some of the warming effect of greenhouse gases as heat is pumped down into the deep ocean.
Changes in the Pacific Decadal Oscillation can help explain the slowing of warming at the surface. This is a natural ocean cycle that plays out over decades and has been in a cooling phase since 1998.
There have been several similar decades in the recent past when the rate of surface warming slowed. But after each of these ended, there was a marked ramp up in heating at the surface.
Greenhouse gas warming certainly won't be linear, with the same increase in heat recorded in each successive decade. But the overall trend is clear – global warming hasn't paused and the climate system continues to warm."
Dr Sophie Lewis is a research fellow in climate science, based the University of Melbourne and the ARC Centre of Excellence for Climate System Science.
"The Earth has warmed significantly over the last century, and particularly strongly since 1970 up to the present. The global average air temperature has risen by 0.89 degrees Celsius over the 1901-2012 period, and the decade 2001-2010 was the warmest on record.
But global average air temperature is only a very small part of the warming story, as the atmosphere absorbs only 3 per cent of the additional heat trapped by the increasing concentration of greenhouse gases. By far the biggest player in the climate system is the ocean.
Over 90 per cent of the warming since the mid-20th century has occurred in the ocean, and the heat content of the ocean has risen steadily since about 1970 with no pause or slowing of the rate over the past 15 years. That is really the "smoking gun" of warming. But there is even more evidence of a strongly warming Earth.
The ice cover over the Arctic Ocean is decreasing rapidly, at a rate of about 4 per cent per decade since 1979. Such rapid ice loss is unprecedented in the last 2,000 years.
Sea level has risen by 19 cm over the 1900-2010 period. This observed rate of rise over the past century is unusually high in the context of the last 2,000 years.
Glaciers and ice sheets around the world are shrinking and losing mass. The combined rate of mass loss from the large polar ice sheets on Greenland and Antarctica was about 350 billion tonnes per year for the period 2002-2011, and is accelerating.
It is even more telling that the rate of sea-level rise, the rate of decrease of Arctic sea ice extent, and the rate of mass loss from Greenland and Antarctica have all increased in the period from the 1990s to the present, compared to earlier periods. This is exactly the opposite of what one would expect if warming of the Earth is slowing or has stopped.
All of this evidence points to the continued strong warming of the Earth since the mid-20th century up to the present, in stark contrast to the erroneous reports purported to be based on leaked drafts of the IPCC assessment."

That's the problem when people motivated by politics and not science cherry-pick from things they don't understand. They usually get it wrong. Just like this ^^^.
Or we could just go watch Al Gore's Oscar winning documentary in the English schools. Oh wait...no we can't. Their courts found it contained so many falsehoods and inaccuracies that they ordered it stopped from being shown.
Thank you, I already did. Unfortunately, you don't seem to know how to read a graph.
You clearly "read" things that don't exist.
Please show me where your claim that "even the IPCC reports admit" that "the global temperature has not risen since 1998" exists?
(Not that you can read the report yet - only the Summary was just released)
