Local weather change weakens the ocean currents that form the climate

This is the final edition of Night Owls, an open topic
that has been published by Daily Kos since 2007.

Bob Berwyn at Inside Climate News writes:Climate change is weakening the ocean currents that shape the weather on both sides of the Atlantic. The change in the ocean’s main heat pump could bring more heat waves to Europe, increase sea level rise in North America, and force fish to move further north:

Since the end of the last Ice Age, a swirling system of cross-ocean currents has been constantly changing in the Atlantic, distributing thermal energy along the surface of the ocean from the tropics to the poles, with heavy, cold water slowly flowing back to the equator at the bottom of the sea.

Collectively known as the Atlantic Meridional Overturning Circulation, the currents played a key role in shaping the climate in eastern North America and western Europe and thus in the development of the civilizations there. But in the 20th century the edition did weakened more than any other time in at least the last 1000 years shows new research.

Along with other studies The new findings show that global warming is driving the slowdown and that the circulation will become even more weak in the coming decades. This could lead to extremes of heat and cold in Europe and a rapid rise in sea levels along the east coast of the United States. When it gets weaker, pools of warm water form. That can lead to it Ocean heat waves, with increasing evidence that overheated oceans are linked to droughts and heat waves on nearby land areas. […]

“If we continue to drive global warming, the Gulf Stream system will continue to weaken by 34 to 45 percent by 2100, according to the latest generation of climate models,” said the co-author Stefan Rahmstorf, a climate researcher with the Potsdam Institute for Climate Impact Research. […]

It’s also important to consider how the changes will affect ocean ecosystems, he said. Some of the currents associated with the overturning of the circulation are important in the spread of coral larvae. Because changes in current also affect temperature and salinity, they likely shift the production of plankton, the bedrock of the ocean’s food chain. […]

QUOTE

“The environmental movement could do better to take the message about the link between poverty and environmental degradation and get that message across to the ground. This will help environmental leaders see the human face of environmental problems – both internationally and domestically – and understand how this connection shapes priorities. For example, understanding what poor people value in the environment (which may not be viewed as “globally valuable” by supporters in the Global North) or the challenges poor people face in trying to address the immediate needs of a family and the medium and the Medium’s long-term need to protect environmental resources. When a child goes hungry, a family may not think about long-term sustainability or damage to ecosystems that support endangered species. You can help the environmental movement recognize this dilemma so that together we can find global and local solutions that also address short-term challenges. “

BLAST FROM THE PAST

That day at Daily Kos in 2009– –The truth, yeah, but please hold the cop back::

“Truth and Reconciliation” has a pleasant, non-partisan appeal that lies behind everything. With its links to icons of resistance and justice Nelson Mandela and Desmond Tutu, the concept is armed with heavy armor against anyone who would dare to criticize it. But the proposed commission of inquiry today announced Senator Pat Leahy is investigating the United States’ detention, transfer and treatment of detainees Not be called as Leahy suggested that Truth and Reconciliation Commission, conjured up by all these names.

The torture commission resonates in a nutshell. Or name it whoever is chosen to be the co-chair for.

To be sure, the truth Got to to be revealed. Or rather, we need to add to the truths we already know about what happened and who ordered it. But it is premature at best to marry Truth and Reconciliation before even calling the first witness in a relentlessly thorough investigation. Let everything that is ultimately uncovered in the probe determine how the subsequent action should take place properly.

Already known evidence conclusively shows that the Cheney-Bush administration violated the Geneva Conventions and committed war crimes. That this was achieved under the color of “legal” memos, most likely not created independently by the legal department, but with the full consent of those who wanted to protect the memos, makes it all the more imperative that there is no T&R style, sorry before the torture squad’s microphones are even turned on.
