•“Overall, the most robust global changes in climate extremes are seen in measures of daily temperature, including to some extent, heat waves. Precipitation extremes also appear to be increasing, but there is large spatial variability"
•"There is limited evidence of changes in extremes associated with other climate variables since the mid-20th century”
•“Current datasets indicate no significant observed trends in global tropical cyclone frequency over the past century … No robust trends in annual numbers of tropical storms, hurricanes and major hurricanes counts have been identified over the past 100 years in the North Atlantic basin”
•“In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale”
•“In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems”
•“In summary, the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century due to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice. Based on updated studies, AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated. However, it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950”
•“In summary, confidence in large scale changes in the intensity of extreme extratropical cyclones since 1900 is low”

I don't think the tune is changing very much.


IPCC Sharpens Warnings in Draft of New Climate Change Report

Global warming is here, human-caused and probably already dangerous — and it's increasingly likely that the heating trend could be irreversible, a draft of a new international science report says. The United Nations' Intergovernmental Panel on Climate Change on Monday sent governments a final draft of its synthesis report, which combines three earlier documents. There is little in the report that wasn't in the other more-detailed versions, but the language is more stark and the report attempts to connect the different scientific disciplines studying problems caused by the burning of fossil fuels, such as coal, oil and gas.

The 127-page draft paints a harsh warning of what's causing global warming and what it will do. "Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems," the report says. It mentions rising sea levels and extreme weather, such as heat waves, flooding and droughts. The final report will be issued after governments and scientists go over the draft in October in Copenhagen.

I started my thread before I read this one. Amazing how two people can refer to the same report and have views that are 180 degrees apart. As in my thread I am not judging anyone here either.

If any of you people really believe that there is anything mankind will do to prevent the next ice age or any other type of climate change then do it and leave the rest of us alone. There isn't a dam thing we can do that will prevent the climate from changing, it is going to happen, it has happened before, many times and will again no matter what humans do. could we possible slow it down from happening by a few years if everyone every where stopped doing everything. Sure, but that ain't going to happen ether.

So leave me the fk alone !

Actually, yes I do because we have unlocked far more carbon and other pollutants than people can fathom. I know it's hard to wrap our minds around just how much but it a lot since the industrial revolution. No amount of comparison to volcanic eruptions will change the fact that we have added to the emissions and we have added things that earth normally doesn't because we figured out chemistry. Yea us. Can earth out do us? I assume yes but we are certainly competition.

So, yes. I think we have. The impact? I guess we will just wait and see but as some scientist say, if we are causing a problem, it's probably too late to fix and we will enjoy the outcome. But to assume we can't compete with earth is pretty myopic. We can and we do - really well.
