1524) Aquecimento global: um pouco de gelo na fervura

Um amigo, Pedro Erik Carneiro, funcionário federal em afastamento para estudos em Cambridge, mandou uma mensagem a seus amigos para alertar sobre a novidade do momento: o esforço (aparente) de alguns cientistas para minimizar os dados que contrariam a visão do momento de que a Terra está em fase de aquecimento global.
Eis o que ele nos escreveu:

Caros,
O assunto de hoje é quase uma bomba: um hacker invadiu um importante centro de pesquisa climático na Inglaterra (University of East Anglia's Hadley Climatic Research Centre) e pegou vários emails de importantes cientistas. Em muito desses emails se mostra uma tentativa de se esconder a perspectiva de queda nas temperaturas e não global warming, por meio ínclusive de manipulação. Isto está em muitos jornais e blogs. Abaixo, vai o texto do Wall Street Journal sobre o assunto.

Se quiserem conhecer alguns emails, é só ir na página da notícia do jornal (http://blogs.wsj.com/environmentalcapital/2009/11/20/hacked-sensitive-documents-lifted-from-hadley-climate-center/) e clicar nos links que dão acesso aos emails.
Ou para uma visão geral acessem o blog de um dos mais conhecidos céticos ingleses (http://jamesdelingpole.com/2009/11/21/climategate-the-final-nail-in-the-coffin-of-anthropogenic-global-warming/) - James Delingpole
Abraço,
Pedro


Hacked: Sensitive Documents Lifted from Hadley Climate Center
By Keith Johnson
The Wall Street Journal, November 20, 2009

Well, this should get interesting.

The Hadley Climate Research Unit in Britain was hacked yesterday, apparently by Russian black hats, and thousands of sensitive documents, including emails from climate scientists dating back a decade, were posted online. More here.

Officials at Hadley, a leading global-warming research center, have apparently confirmed to an Australian a Kiwi publication that the documents are genuine.

The whole affair has much of the blogosphere alight. Blogs skeptical of man-made global warming see blood in the water.

Some of the old emails from scientists made public apparently make references to things like "hid[ing] the decline," referring to global temperature series and different ways to slice and dice climate data.

In all, it seems there are more than 3,000 files in the hacked folders, which have been reposted in various places on the Internet.

The big Copenhagen summit had lost a lot of its appeal in recent days, as world leaders kept dialing down expectations for the climate talks. Maybe this will spice things up.

PS.: Eis o que Rolandes Voador, um leitor deste blog, me mandou:

Alleged CRU Emails - Searchable

Enter keywords to search (no need for quote marks)

On 20 November 2009, emails and other documents, apparently originating from with the Climate Research Unit (CRU) at the University of East Anglia.

If real, these emails contain some quite surprising and even disappointing insights into what has been happening within the climate change scientific establishment. Worryingly this same group of scientists are very influential in terms of economic and social policy formation around the subject of climate change.

As these emails are already in the public domain, I think it is important that people are able to look through them and judge for themselves. Until I am told otherwise I have no reason to think the text found on this site is true or false. As of today, Saturday 21 November, there have been no statements that I have seen doubting the authenticity of these texts. It is here just as a curiosity!

some minor tweaks to the search and browsing functions:
You can now search for a filename by typing the number (with or without the .txt extension)
Results have had some tweaks to the weighting, you still get exact matches first, and then keywords from your phrase. Still removing some common English words from this, but getting there!
Added a basic keyword counter which will show you the kind of the texts that are being looked for.
There is an option when browsing to show 10, 25, 50 or 100 emails at a time. (Hint, you can put any number less than 100 in the pp= part of the query to get that number of results. I'm limiting this to 100 at the moment, on current usage the search will use about 2Gb transfer per day, I don't want it to go much farther than this.

* Page 1 (...) * Page 43

I really just made this because I really couldn't see me going through the sheer number of text files in any realistic fashion. This will help me find emails that are being discussed on forums and blogs I read.

But this page is now being hit a lot, so I feel it only fair that I tell you what I am hoping to get done - and for you to send me suggestions or ideas (or tips). I'm hoping to get the time tomorrow to also make the various Word and Excel files online and searchable, and also to do what I can with the text from the PDF files (some might be easier than others). I am also hoping to get some improvements done to the overall search box to make the results weighted to number of hits for main keywords / filter out unimportant words (you, me and I) and make the tool more useful.

The entire thing is running off a single mysql database and three main php scripts, the emails are parsed automatically into the database and there is also another file that I made earlier that generated hard copy html files just to get something online. If anyone wants to host a copy all you need is a php/mysql system - drop me a line and you can have all the source.
