Carbon Emissions - one problem among many

The debate on climate change often focuses on the level of Carbon Emissions (CO2) and global warming but the overall complexity of the earth's environment means there are several other possible serious factors to consider. Some of  these are listed below - 
Acid Oceans: the amount of carbonic acid in the oceans and the loss of aragonite,
Ozone Depletion: this was the environmental issue of the 1970s and remains a current concern as trapping warmer air closer to the surface of the planet means a colder stratosphere and hence ozone comes under threat again from those chemicals still is use which deplete it.
Fresh Water: Water is becoming so scarce in many parts of the planet, despite unseasonal periodic flooding that underground aquifers are being pumped out and cannot be replenished,
Biodiversity: continued mass extinction of species has considerable impact on ecosystems and on human habitation - the current rate of change has far exceeded levels of adapatability,
Nitrogen and Phospherus cycles: agriculture and fertilisers, burning fossil fuels/timber/crops and human sewage have contributed nitrogen in such quantities that dead zones and algae blooms are now more frequent in the oceans,
Aerosol Loading: dust, sulphates and other particles created by human activity continue to affect air quality and hence have a negative impact on agricultural crops and human health,
Chemical pollution: There are almost 100,000 different human made chemicals now in use on the planet among these are toxic heavy metals (such as lead) and persistent organic pollutants (such as DDT, PCBs and dioxins).  These have strong detrimental effects on humans.

Many of these factors are causally linked to each other and only a comprehensive strategy on climate change togther with a wider linkage to other aspects of pollution has any hope of succeeding.

Up in the Air - George Clooney hits home again


George Clooney's latest film directed/written by Jason Reitman (and based on the novel by Walter Kirn) is another clever subtle and ultimately ironically funny observation on the usually sad spectre of corporate restructures. Clooney's character is corporate downsizing expert Ryan Bingham, whose specialty is to help ease the transition of long-term employees to unemployment. Clooney's character takes his job very seriously and loves the 290 days spent travelling away from home. His only problem is the 70 days at home in his rented empty apartment. His professional world is up-ended when a young Ivy League graduate comes to  the company and threatens to ground the downsizing consultants by the innovative and cost cutting idea of firing people via the internet.

Ryan Bingham is not standing for a change in life, nor the chance of missing the goal of reaching total airline miles to gain lifetime status recognition ("Let's just say I have a number and I haven't hit it yet"). His mission becomes one of proving how personal his job really is and how important a face to face meeting can be to talk down an emotionally unstable person facing unemployment.

In this travelling story both Ryan and the recent college graduate, Natalie, played by Anna Kendrick, both reach realisation as to what has been lacking in their lives, how to become better people and open themselves to love, heartbreak, and the need to mature. The film touches on the many elements of modern corporate life and relationships in this electronic interconnected world.
