That is the ultimate version of Evening Owls, a themed open thread
that has appeared at Each day Kos since 2007. 


Bob Berwyn at Inside Local weather Information writes—Climate Change is Weakening the Ocean Currents That Shape Weather on Both Sides of the Atlantic. The change in the primary ocean warmth pump may convey extra warmth waves to Europe, improve sea stage rise in North America and pressure fish to maneuver farther north:

For the reason that finish of the final ice age, a swirling system of ocean-spanning currents has churned constantly within the Atlantic, distributing warmth vitality alongside the ocean floor from the tropics towards the poles, with heavy, chilly water slowly flowing again towards the equator alongside the underside of the ocean.

Collectively referred to as the Atlantic Meridional Overturning Circulation, the currents performed a key function in shaping the local weather of jap North America and Western Europe, and thus the event of civilizations there. However within the twentieth century, the circulation has weakened greater than at some other time throughout no less than the final 1,000 years, new analysis exhibits.

Along with other studies displaying that world warming is driving the weakening, the brand new findings counsel that the circulation will lose much more energy within the a long time forward. That might trigger warmth and chilly extremes in Europe and fast sea stage rise alongside the East Coast of the US. Because it weakens, swimming pools of heat water type. That may result in ocean heat waves, with increasing evidence that overheating oceans are linked with droughts and warmth waves on close by land areas. […]

“If we proceed to drive world warming, the Gulf Stream System will weaken additional, by 34 to 45 p.c by 2100 in response to the most recent technology of local weather fashions,” mentioned co-author Stefan Rahmstorf, a local weather scientist with the Potsdam Institute for Climate Impact Research.  […]

It’s additionally necessary to think about how the modifications will have an effect on ocean ecosystems, he mentioned. A few of the currents related to the overturning circulation are necessary for dispersing coral larvae, and since modifications to the present additionally have an effect on temperature and salinity, they’re prone to shift the manufacturing of plankton, the inspiration of the ocean meals chain.  […]

QUOTATION

The environmental motion may do a greater job incorporating the message in regards to the connection between poverty and environmental degradation, and constructing that message on the grassroots stage. That can assist environmental advocates see the human face of environmental points —internationally in addition to domestically—and perceive how that connection shapes priorities. For example, understanding what poor populations worth within the surroundings (which is probably not what’s deemed “globally beneficial” by supporters within the world north) or the problem poor folks face when making an attempt to steadiness quick must feed a household and the medium and long-term want to guard environmental assets. When a toddler is ravenous, a household is probably not ready to consider long-term sustainability or injury to ecosystems that assist endangered species. You’ll be able to assist the environmental motion see that dilemma so we are able to come collectively round world and native options that tackle brief time period challenges as properly.”

BLAST FROM THE PAST

On this date at Each day Kos in 2009The Truth, Yes, But Hold Back the Cop Out, Please:

“Reality and reconciliation” has a nice, post-partisan, get-it-all-behind-us attract to it. With its ties to these icons of resistance and justice Nelson Mandela and Desmond Tutu, the idea comes geared up with heavy armor in opposition to anybody who would dare criticize it. However the proposed commission of inquiry introduced right now by Senator Pat Leahy to analyze the detention, switch and remedy of detainees by the US ought to not be referred to as, as Leahy has instructed, the Truth and Reconciliation Commission, with all such a reputation conjures.

Torture Fee resonates succinctly. Or title it for whomever is picked as co-chairs.  

To make sure, the reality should be uncovered. Or, moderately, we should add to the truths we already learn about what occurred and who ordered it to happen. However it’s untimely – at finest – to wed reality and reconciliation earlier than even calling the primary witness in what must be a relentlessly thorough investigation. Let no matter is in the end uncovered within the probe decide what must be the correct course of subsequent motion.

Proof already well-known demonstrates conclusively that the Cheney-Bush administration violated the Geneva Conventions and dedicated warfare crimes. That this was completed beneath the colour of “authorized” memos which most probably had been crafted not independently by the Workplace of Authorized Counsel however moderately with the complete connivance of these whom the memos sought to guard makes it all of the extra crucial that no T&R-style pardon be granted earlier than the Torture Fee’s microphones are even turned on.
