3. Tidal gauge estimates Figure 6. Photo of a tidal gauge at a harbour in Alaska, by Daniel Cornwall. Taken from Flickr, under Creative Commons (BY-NC-SA 2.0). Click to enlarge. The main data sources available for estimating sea level changes are records from tidal gauges, such as the one in...

Once again you comeup empty.. Maybe you will have better luck with sea levels. Hollywood and the media have helped created a popular perception that humans are causing dramatic sea level rises by man-made global warming. This perception comes from an exaggeration of more modest, though...

Yes but he is subtly doing what he does best. He is becoming a 'victim' post by post, 8 posts of fluff after making baseless claims, he is being pressed on to substantiate, and within another 2 or 3 posts he will declare himself as being bullied and harassed. As I said I think that the...

Your done becase you cannot fault their conclusions, or back up any of your claims about bias, data manipulation or conclusion. You have been 'done' since you made the false claims, they were baseless, and they still are. And thats the 8th reply you have made, thats devoid of any sign of...

Think ive seen that even over here, im going to google it.

Look it is simple, are their conclusions sound so far. Yes or no. If not then show us where they are in error, its such a simple request, that you have spent 7 posts pretending to have answered, but have not yet even attempted in reality, speaks volumes for the integrity you bring to this debate.

Again you fail to grasp the nettle, its not written for you, its a summary of an essay written for fellow scientists, they have no interest in your opinion. Altho they will be polite and courteous if you can ever actually find fault with their conclusions, all your responses consist of fluff...

That would be a mistake. Some scientists argue that there has been a natural global warming trend. Other scientists argue that there has been some man-made global warming, but that most of the global warming is natural in origin, and that man-made global warming will only gradually become...

4. Why do people think there is a scientific consensus? It seems that instead of there being a 97% scientific consensus amongst climate scientists on man-made global warming, there are actually a lot of different views. This shouldn’t actually be surprising. Science is a dynamic subject in which...

Now, can you please explain why, if all the scientists in the world believe that AGW is a myth, Many people (including many scientists) believe that there is a strong scientific consensus that increases in atmospheric CO2 concentrations cause dangerous man-made global warming, and that if we...

Once again we fall back into the trap of quoting my scientist vs. your scientist, my data vs. your data No we dont, theres nothing factually incorrect about their conclusions as you claim. If there is, please show me clearly and concisely. If there is data manipulation as you claim, please...

Welcome to the debate Pickles.

As I said I think that the Connolly's, like both sides of the climate debate, manipulate data for their own means so I can't agree that there is definitive science being presented here. Yes we know you said, but you didnt say what, how or where you dont agree, all you are demonstrating is...

Its actually A Science overview of science for science, not us, we are just lucky they put in 100s of hours putting the summaries together for none science folk.

7. Conclusions The main basis for the claim that there has been “unusual” global warming since the late 19th century is that the global temperature estimates constructed from weather station records suggest a warming trend of about 0.8-1.0°C since about 1880. Man-made global warming theory...

6. Paper 3. How heavily urbanized are the stations used in the global temperature estimates? Summary of Paper 3In Paper 3, we carried out a detailed assessment of the extent of urbanization bias in the Historical Climatology Network datasets. These are the main weather station archives used for...

5. Paper 2. An assessment of the NASA GISS urbanization adjustment method Summary of Paper 2 The NASA Goddard Institute for Space Studies (NASA GISS) is the only group using weather records to construct global temperature estimates that explicitly adjusts their data to correct for urbanization...

3. Isn’t there other evidence for global warming? At this stage, you are probably thinking “…but, it’s not just the weather record analysis – there’s loads of other evidence for global warming – the Arctic sea ice is melting, the oceans are heating up, sea levels are rising, etc.” You’re right –...

The paper was on ice trends. This is urbanisation bias. In this essay, we summarise the results of our three “Urbanization bias” papers, which we have submitted for peer review at the Open Peer Review Journal. Urban areas are known to be warmer than rural areas. This is known as the “urban...

3. The pre-satellite era A few groups have attempted to construct sea ice estimates for the pre-satellite era using various combinations of land, ship, submarine, buoy and aircraft measurements made over the years, e.g., the Chapman & Walsh dataset or the Zakharov dataset (Note that the server...
