Varsovia: Se calientan las conversaciones sobre el cambio climático (COP19)

[Visto: 591 veces]

El enfrentamiento entre los países en desarrollo y los desarrollados en la COP19 en Varsovia es solo el principio del sálvese quien pueda. Nadie hará nada por nosotros, solo nos tendremos a nosotros mismos para enfrentar las consecuencias del cambio climático.

Desde principios de 2013 se cocinaba una propuesta para crear una nueva división de las Naciones Unidas con dos objetivos, establecer un programa por país para fijar metas en las emisiones de gases de efecto invernadero, y uno segundo constituir un fondo que permita financiar programas de adaptación, transferencia de tecnologías, supervisión y regulación del mercado de bonos de carbono, y socorro frente a las consecuencias del cambio climático en los países en desarrollo.

Puede al respecto leerse el artículo de Nancy Birdsall, luego de Doha 2012, sobre el posible papel de China y los BRIC en la lucha contra el cambio climático. La idea inicial supone un organismo financiado por la países en desarrollo, y hasta ubicado en la segunda ciudad de alguno de los países en desarrollo o emergentes, pero las cosas siempre son más complejas, a la mayoría sino a todas las potencias (incluyendo Rusia) no les gustaría tener a China como el nuevo líder mundial.

La discusión en Varsovia de este fin de año se ha puesto tensa luego de que los países en desarrollo liderados por China y los BRIC propusieran compensaciones por los daños producidos por los fenómenos climáticos extremos, como el tifón Yolanda en Filipinas, y que los países desarrollados se niegan a discutir hasta después del 2015. Y menos dispuestos están a crear una agencia de naciones unidas que maneje el tema de las indemnizaciones, o que establezca límites a las emisiones futuras.

Todo esto demuestra que los escépticos siguen dominando las políticas en los países desarrollados, que si bien reconocen su responsabilidad (en particular la UE), no tienen propósito de enmienda. Hay un año para tratar de encontrar un camino y comenzar a preparar en Lima 2014 las bases de lo que debe ser un nuevo acuerdo mundial sobre el cambio climático.

Estados Unidos se prepara para enfrentar cambio climático

La previsión de desastres por exacerbación de eventos naturales ha persuadido a la administración del presidente Obama para crear un consejo que estudie y ponga en marcha mecanismos para que las comunidades del país estén preparadas frente a eventos extremos.

Obama orders US communities to prepare for climate change

November 02, 2013

In another move to address the impact of climate change, President Barack Obama ordered a bipartisan task force on Friday to help U.S. communities brace for longer heat waves, heavier downpours, more severe wildfires and worse droughts.

Friday’s executive order set up a panel of governors, mayors, county officials and tribal leaders to advise the White House on how the federal government can respond to communities hit by the effects of a changing climate.

Federal agencies were also directed to modernize their programs in ways that will support investments that will help cities and towns gird against extreme weather. More than two dozen agencies will form a council on climate preparedness.

Because no federal legislation to curb climate-warming greenhouse gas emissions is likely to get through Congress due to widespread Republican opposition, the president has been using his executive authority as an alternative to new laws.

Friday’s White House order builds on a Climate Action Plan unveiled in June, the centerpiece of which was new regulations to be applied to power plants, and comes three days after the anniversary of the landfall of Superstorm Sandy, which caused more than $US60 billion in damage along the U.S. Atlantic coast.

Energy Secretary Ernest Moniz on Friday cited the damage caused by Sandy as a “stark reminder of how disruptions to our nation’s critical infrastructure have far-reaching economic, health, safety and security impacts.”

The task force is to report to the White House within a year on how the government can best “remove barriers, create incentives and otherwise modernize federal programs to encourage investments, practices and partnerships that facilitate increased resilience to climate impacts, including those associated with extreme weather.”

No new federal funds were offered to support the task force.

Eight Democratic but no Republican governors are on the bipartisan panel, even though some of the states hardest hit by extreme weather conditions, including New Jersey, Florida, Arizona, New Mexico and Texas, are governed by Republicans.

States like Florida and Texas face acute financial exposure from extreme weather and climate-related events, according to a report this week by Ceres, a coalition of investors, companies and public interest groups that advocates for sustainable business practices.

Extreme weather events in 2012 cost U.S. taxpayers more than $US300 apiece, or $US100 billion ($106 billion)  in total, most of it to pay for federal crop, flood, wildfire and disaster relief, Ceres President Mindy Lubber said in a statement.

Daniel Weiss, a climate strategy expert at the Center for American Progress, said the task force should assess future costs to make communities better prepared and less vulnerable to extreme weather.

“This bipartisan group of state and local officials could be persuasive advocates to an otherwise recalcitrant Congress that federal investments in community resilience will reduce spending on disaster recovery,” Weiss told Reuters.

The progressive think tank estimates that in fiscal 2011-2013, the U.S. government spent $US6 on disaster recovery for every dollar on community preparedness.

A fact sheet on the new task force is available at

Separately on Friday, the Environmental Protection Agency released its draft climate change adaptation plan and called for public review and comment.

“EPA must help communities adapt to a changing climate,” said EPA Administrator Gina McCarthy. “These implementation plans offer a roadmap.”

Existe un mapamundi que permite ver que ocurre si se eleva el nivel del mar, uno puede hacer el cálculo tomando como vase 6, 18 y 100 pulgadas (15.24, 45.72, 254 centímetros). De acuerdo con el IPCC podría subir por encima de 30 púlgadas (82 cm).

Con el cálculo del IPCC Australia ha comenzado a tomar algunas previsiones:

Coast protection costs rise with sea levels 

Anne Davies November 03, 2013
Sydney councils and the state government are facing a multibillion-dollar bill to strengthen and maintain sea walls around the harbour and beaches in the face of rising sea levels.
But despite the threat to low-lying areas, housing densities are increasing in high-risk areas. New developments are being constructed in areas that depend on sea walls around Manly lagoon, at Rushcutters Bay, Double Bay and along the Parramatta River.
If the 82-centimetre rise in the sea level predicted by the Intergovernmental Panel on Climate Change is realised by 2100, coastal developments the length of the NSW coast will be at risk.
In Sydney, the hundreds of kilometres of walls around the harbour will become increasingly vulnerable to stronger wave action in deeper water. These waves can scour out the footings and cause ”overtopping”, when waves slop over a retaining wall and erode it from behind.
The threat comes not just from seawater advancing onto land. Sydney Coastal Councils executive director Geoff Withycombe said higher sea levels are likely to raise the water table and alter the flow of stormwater into the harbour.
This has been a concern during the approval process for the Kiaora Lands development at Double Bay.
