Planetwatch series – Are climate change theories overestimated

Planetwatch IV

Climate Change Theories Over-estimated?
Recent research by a team of scientists at Bristol, UK has established that atmospheric CO2 levels have not changed substantially since 1850 even though emissions have increased 17 fold. This indicates that nature’s capacity to soak up atmospheric CO2 have not diminished contrary to previous projections which signalled a reduction in the capacity of oceans to absorb CO2 as temperatures rise. The study also concluded that green house gas emission figures currently attributed to deforestation is grossly overestimated.

Dalai Lama on climate change
During a speech delivered at Tawang, Arunachal Pradesh the Dalai Lama exhorted people to protect environment and be mindful of the risks of global warming. Good to see that religious leaders are taking cognizance of climate change. Also brings to mind Al Gore’s efforts to introduce a religious twist to his future documentaries to gain wider audience.

Climate change impact on small glaciers
While Antarctic ice melts and retreat of large glaciers have been in the spotlight, effects of climate change on small glaciers have been largely ignored. Recently a team led by glaciologist Prof. Syed Iqbal Hasnain from TERI has undertaken a study to establish benchmark data and measure the recessionary trends of small glaciers across the Himalayas. The team shall also examine the effects of black carbon deposition on glacier melt. Initial results from the study indicate that small glaciers and their tributaries are retreating at a faster rate. Large glaciers like Gangotri are also receding. Since the region is dependent on glacial melt water, the adverse impact of glacial retreat on the environment could be significant.

Jute Geotextiles
Geotextiles are permeable fabrics used to strengthen the soil or protect soil against erosion. Geotextiles were typically made from polypropylene and polyester. Eco-friendly geotextiles made of jute and coir are becoming more popular. The new materials are “earth-friendly” and bio-degradable and have a life span of 3 – 5 years.

Plasticki
 

Plastiki logoThe Plastiki is a catamaran made of reclaimed plastic bottles and recycled material getting ready to set sail from San Fransisco, USA on its way Sydney, Australia. En Route the vessel shall visit 12 ecologically susceptible locations, including the Great Pacific Garbage Patch. On board shall be a team of scientists and artists led by David de Rothschild, a prominent ecologist. The purpose of the journey is to bring to attention the enormous amount of garbage being disposed in the sea.
