Geographical Conference 2013 Lecture Snipets: Chironomids & Hazards in Kathmandu


Lecture 1: The past is the key to the future for understanding climate change: the importance of chironomids as temperature indicators

In recent years, the use of midges as quantitative indicators of past temperatures has greatly expanded.

Below is a brief summary of Dr Barbara Lang's Lecture on  'Changes in temperature and Society over the last 15,000years' (Edge Hill University):

Favourite line: Need to explore and understand the past in order to see how the system works.

-          Always been natural climate vulnerability; important to look at past to see how system works

-          Chironomids: non-biting midges found in most environments as pioneer species used as evidence

-          Paleo records also used like Pollen and hunan bone/hunting records.

Q: What lessons can we learn from the past for now?

Q: How is climate change going to affect the human population differently (winners & losers)

Lecture 2: Future trends in natural hazard loss


Below is a brief summary of Professor David Petley's Lecture on  'Future Trends in Natural Hazrad Loss' (Durham University)


Favourite line: Geography is the key discipline which integrates the physical and human world.

-          The next big plus 8.0 earthquake - 1million fatality or $1 trillion dollar loss.

-          Regarding unpredictable earthquakes, the future will be the same as past, just more expensive!

-          Increasing vulnerable population with a false sense of security (low hazard perception).

-          There has been a clustering of earthquakes overt time (1950s/60s cluster; now 2005 since Sumatra).

-          Next big one, Kathmandu
Q: Research why Kathmandu is so vulnerable?

Clipperton Project Update

For those of you that have been following the progress of the Clipperton project will be please to watch the new trailer which shows the findings of the group's recent expedition earlier this year!


The Clipperton Project is a multi-disciplinary, international arts and science project which aims to take outstanding practitioners in the arts and sciences on expeditions to little-studied, inaccessible and complex territories which have been isolated by history.

Rio 2012: 20years on from sustainable development

How has our attitude to the environment moved on from Rio 1992 when the paradigm of sustainable development was first publicy showcased.

Have we become a more globally and environmentally aware society?
Are we looking after the environment better and has our attitude to it changed from consumption to protection?

We will move towards a green economy in the next 50years? and more possibly are we on track to achieve the MDGs?

Arctic melt releasing ancient methane

Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere.This article is a good link to Edexcel Unit 1 World at Risk to show the possible impacts of global warming and positive feedback mechanisms...

An Ocean of troubles - our attitude to the ocean environment

To what extent does the state of our oceans depict the global attitude to the environment?


Last night Simon Reeve's Indian Ocean programme  highlighted the state of the oceans in the tourist hot spot of the Maldives and how some islands are being used for waste dumping!

Ecological footprint

An ecological footprint measures the total amount of land and resources used, it includes your carbon footprint but goes further.See how your choices affect the environment and whether you are living beyond the capacity of the planet by clicking here - http://www.ecologicalfootprint.com/

Whose water is it?

Fred Pearce's article provides an excellent service in highlighting the chronic problems around the world of excessive groundwater exploitation - but it may not be taking us much further forward in finding solutions...what's your opinion?

Check out this month's New Scientist - Whose water is it? Very good for water security and conflicts.

Brazil's new forest law: short term economic gains over long term environmental security?


A\member of Congress protests as the Chamber of Deputies holds a plenary vote on the forest code 25 April 2012Despite the countless geographical case studies, the radical environmental groups and lobbyists and a global increased environmental awareness, it saddens me to read that yet another emerging superpower, one of the BRICs nonetheless, has chosen to put economics over environmental protection.  After over a year of political wrangling Brazil's government have passed a law ( 247-184) which eases rules on how much land farmers must preserve as forest. Now, i know it is easy for me with my Western perspective to sit here an chastise the Brazilian government for following the lead of the hegemonic USA and post industrial attitude of China, but having been and for a short timed lived in the Amazonian rain forest i feel it will be the TNC loggers rather than the indigenous tribes who will reap the rewards.


Once again this issue touches upon the wider themes of how societies (and cultures) view and subsequently protect the environment. With the law now passed it will be interesting, yet very sad to watch how deforestataion rates possibly increase even more over the coming decade and taking a particular morbid line i wonder how many more incidents of this will occur: Loggers 'burned Amazon tribe girl alive'

Ice climbing: Tim Emmett

Frozen limit of endurance: Canadian ice-climber Gadd, with Londoner Tim Emmett, spent four hours battling temperatures as low as -25c to become the first men ever to ascend the 450ft Helmcken Falls in British ColombiaTim Emmett - one of the world's best ice climbers and deep water soloists as well as part time surfer, flying suit jumper and adventure junkie is seen photographed below on the 450ft Helmcken Halls. Tim spent four hours battling temperatures as low as -25c to become the first men ever to ascend the 450ft Helmcken Falls in British Colombia.


This is one of my favourite photographs...ever. The ice is 'spray ice' formed from the splash black of the waterfall.





Long way down: If either of the climbers lost their grip, they faced a 100ft drop into an ice hole

Moss helped cause Climate Change...


The invasion of the land by plants was a pivotal time in our history. It brought about huge changes to our climate”

Finally some common sense...?

Is another  national white elephant about to fall to the axe of common sense? I for one hope so as I am fed up how the debate on alternative energy, especially WIND, has droned on in background like the sound produced from the very turbines themselves!

Alternatives in principle are good (but which alternatives) and yes wind can make a positve contribution in specific geographic areas, but for the masses - simply no!

Davos 2012: Who's afraid of China?

A good one for superpowers: http://www.bbc.co.uk/news/education/

Farmer pulling a cart
China is already the second-largest economy in the world - and yet most of its population is poor

First report on UK climate impact


Headlines for possible negative outcomes, assuming nothing is done in preparation, include:
  • Hotter summers leading to between 580-5900 deaths above the average per year by the 2050s.
  • Water shortages in the north, south and east of England, especially the Thames Valley area by the 2080s.
  • Increased damage from flooding could cost between £2.1bn-£12bn by the 2080s.
The report's positive findings include:
  • The melting of Arctic sea ice opening shorter shipping routes to Asia.
  • Milder winters leading to 3,900-24,000 fewer premature deaths by the 2050s, significantly more than those forecast to die as a result of hot weather.
  • Wheat yields to increase by 40-140% and sugar beet yields by 20-70% because of longer growing seasons by the 2050s.

Durban: an overview

So, they did it, or did they? Ministers worked through the night in a desperate bid to salvage a new global climate deal to tackle climate change at the conference in Africa.

In a week in which India, China and the US had consistently taken a hard line in opposition to proposals for action to curb global emissions and continue/adhere to the Kyoto legacy, it appears that the strong sense of urgency from other nations has brought them round to a legally binding commitment.

So in it's simplest form Durban achieved it's goal - to bring the key polluters, players and stakeholders round a table and agree on a set agenda to tackle global climate change - the barometer of success, as ever, will be who will stick to it 6months, 1year and 5 years down the line...

Why the UN climate change summit is our last chance to save the world


U.N. Secretary-General Ban Ki-moon, climate change summit

A little bit sensationalist for the metro but it is not too bad - aside from the doom and gloom and catchy headlines it turns out that there is a reasonable summary and if you click website there are some excellent links to more recent stories...http://www.metro.co.uk/news/newsfocus/884202-why-the-un-climate-change-summit-is-our-last-chance-to-save-the-world

Poorer countries overtake rich world's consumption carbon footprint

The financial crisis of 2009 saw the developing world's carbon emissions from consumption shoot past the developed world's years earlier than expected, new research shows...

The carbon footprint from consumption in the developing world has overtaken that of the developed world, according to research published on Monday. The change happened years earlier than expected due to the fact that the developing world's emissions were largely unaffected by the global financial crisis.
Emissions within the borders of developing countries outstripped those emitted in developed countries (as defined by the Kyoto Protocol's 'Annex B') in around 2005. But the rich world still accounted for the majority of the carbon footprint of consumption due to the goods it imports from China and other developing economies.
