Climate Change to blame for Pakistan floods?

by admin on Aug.27, 2010, under Environment, News

I asked a similar question just over a year ago, with regards to Bangladesh’s annual floods. Although Bangladesh has flooded this year, as it does most years, and caused hardship and disruption for many thousands of the nation’s poorest citizens it has gotten off relatively lightly compared to the impact that the monsoons have had on Pakistan this year.

Satellite images from last year (left) and earlier this month (right) give an indication of the extent of this year's Pakistan Floods. Terrible though they are, are they just a taste of things to come?

Really, you’d have to be living in a complete news vacuum to have missed the awful disaster which this year’s monsoon floods have caused in Pakistan; The UN has now declared that the scale of the crisis is greater than the combined effects of the Haiti earthquake (Jan ‘10), the Kashmir earthquake (Oct ‘05) & the Asian tsunami (Dec ‘04) and has left over 14,000,000 without food or shelter and at risk of falling victim to the host of diseases which commonly occur in the aftermath of major flooding.
One bright note is that this disaster has seen an unprecedented response from the public, with donations actually increasing as the crisis entered it’s second, then third week; very different from the usual pattern seen in these kinds of cases, where “donor fatigue” tends to kick in after the first week irregardless of how well the effects of the disaster are being dealt with at that stage.
However, for all that the response, both in the UK and internationally, has been amazingly generous so far there is still much work for the aid agencies to do, and many, many flood victims who still need the help of the international community if they’re to have any hope of returning to a normal way of life any time in the foreseeable future!
Unfortunately there are many despicable scammers in this world, and in particular on the internet, who’ll take any chance to profit from the misery of others, so if you’re planning on making a donation it’s best to go through the DEC, or one of their well known, reputable members such as Oxfam who, like most of the major UK charities, now have a page dedicated to the Pakistan Flood appeal.

Anyway, that was all a bit of an aside, an incredibly important aside, but a tangent none the less.
The real question I wanted to ask in this blog post was whether these floods, described as a “once in a century” event, are another sign that Climate Change is indeed a real and pressing problem which should concern the whole global community?

I understand the principle that climate is a long term pattern, and that it can’t judged by single isolated events, no matter how catastrophic, but it seems to me that we’ve been getting more and more of these “once in century” type of weather events over the past decade or so, and I truly wonder how much longer the climate change deniers will be able to keep their heads in the sand and continue to refute that there is a shift occuring in the planet’s weather patterns?
I can accept that there’s still a lot of debate to be had over the extent of anthropogenic climate change, and, in turn, how much humanity can do to mitigate the global climate change, but surely we’re now getting to a stage where denying the existance of a pattern of climate change is a thoroughly asinine position, and one which is only likely to be held by either the woefully gullible or those who are motivated by profound self-interest.

Corpse Flower causes a stink

by admin on Jul.14, 2010, under News, Science, Weird stuff

With a name like “The Corpse Flower” it’s no surprise that Amorphophallus titanium isn’t a big seller for online florists, and that’s before one even considers it’s massive size (they can grow to up to 8m tall) or the bloom’s putrid smell, a trait which evolved to lure insects, responsible for pollination, to the plant.

The Corpse Flower (Amorphophallus titanum)

Flowering only very rarely the Corpse Plant is guarenteed to cause a stink in the botanical world whenever it blooms.

However, amongst botany geeks the Corpse Flower appears to be quite a hit; There aren’t many of them to be found outside the plant’s natural habitat, the rainforests of Indonesia, and they rarely flower in the wild, let alone in cultivation, so maybe it shouldn’t be a surprise that whenever one of these bizarre organisms blooms in captivity flora-philes come flocking to see the unusual sight, and “experience” its unique scent.

On this occasion it’s the specimen held at the Houston Museum of Natural Science (HMNS) which is due to flower, and such has been the buzz it’s created that not only have the HMNS set up a webcam, & a “Corpse Flower Watch” on their blog, complete with daily updates on the plant’s progress and measurements of its growth, but, with the fragrant flower due to open its petals any time this week, they’re also planning on opening the museum 24hrs a day while it’s in bloom.

The plant, named Lois, has also become a bit of a celebrity on Twitter, so if you’re a would-be botanist, but not based within travelling distance of the HMNS you can still keep up to date with its progress minute to minute.

Dubai Airshow 2009- Flights of fancy?

by Mort on Nov.17, 2009, under News, Science

Coming as it does during a period when many of the world’s major economies are still crawling their ways out of recession there have been question marks about how successful the 2009 Dubai Airshow would be in terms of generating sales for it’s exhibitors.

However, as the show progresses it would appear that it’s not all doom and gloom for the aviation industry. It seems that this year’s big winner will most likely be the military hardware sector, and it’s no surprise that companies which produce military aircraft are lining up to take part in the show, one consultancy recently estimated that Middle Eastern spending on military aircraft would top £100bn by 2014.
Amid all the clamour and competition it’s nice to see a British company, BAE, managing to grab it’s share of the sales. It would appear that so far they’re having a pretty good show, as part of the consortium which makes the Eurofighter Typhoon they’ll no doubt have been buoyed up by how much interest the jet fighter has generated from Gulf States during the airshow.

BAE have also generated quite a bit of buzz with the annoucement that their unmanned Mantis aircraft completed it’s maiden test flight recently. This is particularly significant since the Mantis is the first ever fully autonomous, twin-engined UAV. It hasn’t all been military hardware for BAE though, their Avro Business Jet has also proved popular; not only has it been selected by the governments of Bahrain, Abu Dhabi and Dubai as their VIP aircraft, it’s also won orders from the British firm Infinite Engineering Services.

Another big piece of news from the show is the annoucement by the UAE’s national carrier, Etihad, of a £750m investment package to enhance their operations across the board; no doubt they’ve got a few quid to splash around after all the flights to Dubai which they sold to those attending the airshow.

So, maybe the doom mongers are wrong; some sections of the civilian aviation industry might still be looking a little flat but overall it’s obviously far from penniless, and military spending never seems to go out of fashion. Overall it looks like the speculation that the Airshow would be a complete and utter flop may have been a little premature.

Forget the experts, Nanny (state) knows best!

by Mort on Nov.06, 2009, under Health, News, Rants, Science

It’s not the first time we’ve seen the Govt reject the advice of experts when they fail to come to the conclusion’s which the Govt would like them to, but to me the sacking of Dr Nutt, chair of the Govt’s Advisory Council on the Misuse of Drugs, last weekend, when he had the termerity to give an expert opinion which contradicts the Govts uninformed, but official, line, sums up the hubris & utter arrogance which have been hallmarks of both the Brown and Blair govts.

It also quite clearly reveals that the govts objections to cannabis and ectasy seem to come down to “drugs are illegal because they’re bad, and they’re bad because they’re illegal”. Don’t get me wrong, I’m not saying that these drugs are 100% harmless, but if an expert, whose job it is to know, is stating that they’re less harmful than substances which are legal and freely available then surely that has to be a pretty good arguement for their legalisation?
OK, you could take the opposite tack and say that maybe tobacco and alcohol should be made illegal instead, but apart from being a non-starter in terms of getting the populace to accept such a move, not to mention how much it would cost the exchequer in terms of lost duty, there comes a point where govt has to butt out and let people make their own choices (and take responsibility for them) even if there is some risk involved; Else we’ll eventually end up as a society of joyless wage slaves whose only purpose is to be good little workers. I mean, if you want to start talking about banning anything which is dangerous then lets start by looking at privately owned vehicles; how many deaths and injuries do they cause each year on our roads? By contrast we’re talking about cannabis & ectasy, susbstances which routinely kill less people each year than bed related misadventures!

There’s also the fact that history has shown that prohibition doesn’t work, where someone stands to make a profit you’ll just get a black market economy spring up to meet consumer demand for prohibited goods. As things stand in this country millions of otherwise perfectly law abiding, productive members of society are criminalised because they want, and choose, to smoke cannabis. If the govt truly represented the people they’d accept that for most users cannabis is a relatively benign substance with minimal knock on effects for wider society, and they’d legalise it.
Yes I said legalise it, forget decriminalisation, although it’s often touted as an acceptable method for govt to look the other way and quietly accept that maybe cannabis isn’t such an evil drug after all, decriminalisation is in fact the worst of both worlds from a societal point of view. Users are still forced to interact with the black market, organised criminals, in order to get the stuff, and this has a number of wider implications. It means that there aren’t any safe guards on quality, no product information in terms of the strength of any particular batch, and most importantly of all, money spent on cannabis is going to support organised crime!
On the other hand if it were legalised these issues could all be eliminated; users could be sure they knew what they were getting, and wouldn’t be funding criminals, but on the contrary could be providing revenue for govt.

At a time when we’re being told that, due to the banking bail out, our country is going to be in debt for decades to come you’d think that the govt might be open to new means of raising revenue. The Home Office estimates that in 2006 the UK drug trade was worth between £3.5 and £5.8 billion, not enough to solve the country’s money woes, but getting a slice of any figure which is measured in the billions isn’t to be sniffed at!

Really it seems like a no brainer to me. Now that “the genie’s out of the bottle” it’s never going away, people are going to take these drugs, they’ll find a way to get them because someone else can make money from supplying them. When even the experts are saying that dope is less harmful than substances which society already makes freely available, why can’t the govt just get over the outdated dogma that “drugs are bad m’kay” and do the thing which would benefit everbody except the organised criminals?

This piece in the New Scientist lays out the wider picture, in terms of the govt’s rocky relationship with it’s own Advisory Council on the Misuse of Drugs. There’s also a petition running on the No. 10 site here, if you want to join the call to re-instate Dr Nutt.

Global Warming says it with Flowers

by Mort on Oct.05, 2009, under Environment, Science

While doing my rounds of various news sites during a quiet spot earlier, I came across an article called Study Predicts Effect of Global Warming on Spring Flowers, on NASA’s Earth Observatory site.

The study in question was carried out by British and Australian academics & investigated the likely effects of global warming on flowers, and other plant species. My first reaction was actually pedantic rage brought on by NASA’s use of the phrase “Global Warming“. All too often this term is used incorrectly as a synonym for climate change, and it’s one of my pet hates, since the label “global warming” implies that climate change will lead to warmer weather globally; whereas the reality of climate change is that some places will get hotter while others get colder, or that specific locations will become hotter in the summers but get colder winters than they’ve previously experienced.

In short, climate change comes down to much more than the idea that everythings going to get warmer, & I believe imprecise use of the term “global warming”, when one is talking about climate change as a whole, only adds confusion to a debate which is already bogged down in misunderstanding, statistical chicanery, &, at times, downright dishonesty.
For a start it implies that everywhere is going to get warmer, which makes some people wonder “What’s the problem, hotter summers would be nice!”, but it also gives especially ignorant anthropogenic climate change sceptics an excuse to crow on about how “global warming” is a myth, whenever it snows badly, or there’s a cold snap. Of course, what the poor fools are missing is that climate change could very well lead to much hotter, wetter summers for us in the UK, but leave us (in worse case scenarios) with winters they’d be more familar with in Moscow; London’s only a few degrees of latitude south of Moscow, and if the Gulf Stream &/or Jet stream were to pack up it’s likely that the UK would become a good deal colder!

In anycase misuse of “global warming” to mean “climate change” it’s one of my pet hates, and it especially grates when a source which should know better does it, hence my initial reaction to the piece. However, on reading through it I discovered that I had perhaps been too hasty, as the piece in question appears to be looking at a “global warming” scenario, rather than climate change as a whole; Of course how much validity there is in a study which is predicting an overall warming pattern, rather than considering the possibility that weather will become more extreme, and erractic, all round is another question entirely, and one which I’ll maybe rant about another day.

Think of the flowers! wont somebody please think of the flowers?

Think of the flowers! won't somebody please think of the flowers?

OK, “sloppy use of precise terms” rant aside, what did the study actually conclude. Essentially the results shouldn’t be a surprise to anybody, in the sense that generally speaking, it found that warmer winters would lead to plants flowering earlier; However, the predicted scale of these changes is quite surprising. Roughly speaking, for every 1oC that average air temperature rises, plants will start flowering 11 days earlier, although this figure could vary between 7 and 16 days per oC, depending on whether the local climate is oceanic or continental, and how exactly it’s effected by climate change in the longer run.
Near the start of the article it’s stated that flowers could be appearing “as much as 50 days” earlier, than they currently do, by 2080, but, cynic that I am, I assume this figure is based on more extreme climate change predictions, in order to produce an eye-catching headline.

“So what’s the problem?” you may be asking; how do flowers appearing earlier in the year have a negative impact on anyone, except for possibly shops which sell flowers losing sales around Valentine’s day. The answer is that, most likely, there wouldn’t be any direct negative effects for humans, but when one thinks about the numbers of other species, particularly insects, whose life cycles rely in some way on flowers, and other species who, in turn, rely on those species, it’s clear that ecologically this could be a pretty big deal.
A great deal of effort is spent on highlighting how climate change might end up directly effecting humans, and while that is definitely a worthy goal, I think that too often it’s wider ecological effects are only vaguely touched upon. The stark truth is that, despite all of our scientific advances, humanity’s welfare is still, very much, tied to the ecosphere which we inhabit, and if other species which play important roles in the ecosystem start to fail then the overall impact of climate change could be far greater than many realise.
