what is the recorded increase in world temperatures and sea levels world wide due to global warming up to now.?
In all these 30 - 35 years of the so called global warming I have not found any discernible increase in sea level at the Visakhapatnam's beach (Andhra Pradesh, India) or a reduction of beach area. Neither are the temperatures noticeably warmer. Has anybody noticed such changes.

After 1998 temperatures increases started to ease off and after 2005 they started to decline, resulting in a 0.1C decrease in average global temperatures in the last decade.
There is now an emerging scandal where emails from the Hadley Centre (The uk met office department dealing with climate change) show staff discussing how to present the temperature data in a way that disguises the temperature drop.

Over the past 30 years the global temperature has fluctuated approximately 0.5°C and sea levels have risen nearly 9 millimeters.
It is not much, the global temperature difference between an ice age and a warm interglacial period is only about 8°C, and the current rate of sea level rise is right on par with the average over the past 7,000 years, and they're is no acceleration so there is nothing to do anything about.Source(s): Non-Alarmists science.

Don't believe anything you read and only 1/2 of what you see. Of course, Global warming is real. The last Ice age has gone away, has it not? So, we must have global warming. Do people contribute to global warming? Probably some small amount, after all we ARE Warm and we breath in oxygen and breath out CO2, we must be part of the problem. What is Al Gore going to do about it? Kill a whole lot of people? Invariably that is what Socialists do when they take control of a country. Is that better than destroying their economy and causing millions to starve to death?

In all the 4 south Indian states,the difference between the 2 successive tides,i.e.the tidal amplitude is very small,as compared to other maritime states.If the coast is steep,the rise in sea level will not be noticed.If the exposure is vast,say on a mudflat,and if the tide level is same for 2 days with a difference of 10 years(this data can be got from satellite imagery)or even 20 years,then the difference can be seen.Wind also plays a major role in lowering or stepping up the exact tide level at a place,& therefore,one cannot notice it easily.As Vizag is situated on a coastal belt,there will be the effect of sea breeze also & one may not notice the rise in temperature due to humidity.But in maritime states in still higher latitudes,even the coastal temperatures are warmer than what it was earlier.This data can be got from Meteorological Department,for each of the centres.

I've been to several coastal towns where its obvious from buildings and sea walls that many years ago the sea was much higher, so my observations would suggest that sea levels have fallen.Source(s): If you can't see it happening then it isn't

"Current sea level rise has occurred at a mean rate of 1.8 mm per year for the past century, and more recently at rates estimated near 2.8 ± 0.4 to 3.1 ± 0.7 mm per year."
From Science Daily:
"The results are published in Nature Geoscience and predict that the amount of sea level rise by the end of this century will be between 7- 82 cm – depending on the amount of warming that occurs – a figure similar to that projected by the IPCC report of 2007."
"The IPCC used sophisticated climate models to carry out their analysis, whereas Siddall and colleagues used a simple, conceptual model which is trained to match the sea level changes that have occurred since the end of the last ice age."
I don't have data on Visakhapatnam's beach and can't comment on the temperatures on your area, but global warming is concerned with global trends and not so much with temperature variations at certain geographic points. Despite the fact that in 2009 it has been cooler where I live, internationally it will be one of the hottest years on record.

well all i know is that it is slowing down global warming is a function of how fine megan fox looks

Well doing some fancy search and math, I get about 30 years of 3mm/yr to come out to 90mm=9cm= about three and a half inches of sea level rise. Don't feel bad, I probably wouldn't have noticed it either.
If we take the last 10 years at 1/8mm/yr we get less than one inch.
Perhaps we should include this in inserts to the "An Inconvenient Truth" DVD so people can get some perspective (especially Floridians). Maybe we could also include the latest hurricane trends.

No, can't say I have, in fact the satellite records show no warming for ten years. And the independent, non government funded science I've seen suggests sea levels to be as usual.

NASA records it here.
Look for the banner at the top - "Vital signs of the planet." The changes are gradual in human terms, but very fast in geological and ecosystem terms.
Jerry, if you are capable, read the article. It says "2009 is set to be one of the 5 hottest years on record, climate scientist have PREDICTED." In a couple of months, well know where it ranks.
