Adéu a Nihil Obstat | Hola a The Catalan Analyst

Després de 13 anys d'escriure en aquest bloc pràcticament sense interrumpció, avui el dono per clausurat. Això no vol dir que m'hagi jubilat de la xarxa, sinó que he passat el relleu a un altra bloc que segueix la mateixa línia del Nihil Obstat. Es tracta del bloc The Catalan Analyst i del compte de Twitter del mateix nom: @CatalanAnalyst Us recomano que els seguiu.

Moltes gràcies a tots per haver-me seguit amb tanta fidelitat durant tots aquests anys.

El mar no es menja Bangladesh

La massa terrestre ha augmentat a Bangladesh a un ritme de 22 km quadrats per any en els últims 32 anys. Ho diu un estudi científic elaborat per investigadors d'aquell país.
DHAKA (AFP) - New data shows that Bangladesh's landmass is increasing, contradicting forecasts that the South Asian nation will be under the waves by the end of the century, experts say.

Scientists from the Dhaka-based Center for Environment and Geographic Information Services (CEGIS) have studied 32 years of satellite images and say Bangladesh's landmass has increased by 20 square kilometres (eight square miles) annually.

Maminul Haque Sarker, head of the department at the government-owned centre that looks at boundary changes, told AFP sediment which travelled down the big Himalayan rivers -- the Ganges and the Brahmaputra -- had caused the landmass to increase.

The rivers, which meet in the centre of Bangladesh, carry more than a billion tonnes of sediment every year and most of it comes to rest on the southern coastline of the country in the Bay of Bengal where new territory is forming, he said in an interview on Tuesday.

The United Nations Intergovernmental Panel on Climate Change (IPCC) has predicted that impoverished Bangladesh, criss-crossed by a network of more than 200 rivers, will lose 17 percent of its land by 2050 because of rising sea levels due to global warming.

The Nobel Peace Prize-winning panel says 20 million Bangladeshis will become environmental refugees by 2050 and the country will lose some 30 percent of its food production.

Director of the US-based NASA Goddard Institute for Space Studies, professor James Hansen, paints an even grimmer picture, predicting the entire country could be under water by the end of the century.

But Sarker said that while rising sea levels and river erosion were both claiming land in Bangladesh, many climate experts had failed to take into account new land being formed from the river sediment.

"Satellite images dating back to 1973 and old maps earlier than that show some 1,000 square kilometres of land have risen from the sea," Sarker said.

"A rise in sea level will offset this and slow the gains made by new territories, but there will still be an increase in land. We think that in the next 50 years we may get another 1,000 square kilometres of land."

Aquesta informació m'hauria passat desapercebuda si no fos perquè Anton Uriarte la revela en el seu blog. Pocs mitjans l'han publicada.
Si el resultado hubiese sido el contrario nos hubiesen abrasado. Pero como los hechos refutan la teoría, lo silencian. La BBC y el New York Times sí han recogido el informe, pero de una forma tan confusa, que parece que no importa, que el país se acabará hundiendo y se harán realidad las predicciones catastróficas del IPCC, cada vez más negadas por los hechos.

Si se hiciese un estudio semejante referido a la costa española (evolución en los últimos 30 años) apuesto a que el resultado sería el mismo: el mar no ha ganado terreno, lo ha perdido. Pero no lo harán.
