That is the ultimate version of Evening Owls, a themed open thread
that has appeared at Day by 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 might carry extra warmth waves to Europe, improve sea degree 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 persistently 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 another time throughout at the least the final 1,000 years, new analysis reveals.

Along with other studies exhibiting that international warming is driving the weakening, the brand new findings recommend that the circulation will lose much more power within the many years forward. That would trigger warmth and chilly extremes in Europe and speedy sea degree rise alongside the East Coast of america. 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 international warming, the Gulf Stream System will weaken additional, by 34 to 45 % by 2100 in line with the most recent era of local weather fashions,” mentioned co-author Stefan Rahmstorf, a local weather scientist with the Potsdam Institute for Climate Impact Research.  […]

It’s additionally essential to contemplate how the modifications will have an effect on ocean ecosystems, he mentioned. A number of the currents related to the overturning circulation are essential for dispersing coral larvae, and since modifications to the present additionally have an effect on temperature and salinity, they’re more likely to shift the manufacturing of plankton, the muse of the ocean meals chain.  […]

QUOTATION

The environmental motion might do a greater job incorporating the message concerning the connection between poverty and environmental degradation, and constructing that message on the grassroots degree. That may assist environmental advocates see the human face of environmental points —internationally in addition to domestically—and perceive how that connection shapes priorities. As an example, understanding what poor populations worth within the surroundings (which will not be what’s deemed “globally precious” by supporters within the international north) or the problem poor individuals face when attempting to steadiness instant must feed a household and the medium and long-term want to guard environmental sources. When a baby is ravenous, a household will not be in a position 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 will come collectively round international and native options that tackle brief time period challenges as properly.”

BLAST FROM THE PAST

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

“Reality and reconciliation” has a pleasing, 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 immediately by Senator Pat Leahy to research the detention, switch and therapy of detainees by america ought to not be known as, as Leahy has steered, 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 certain, the reality should be uncovered. Or, slightly, we should add to the truths we already find out about what occurred and who ordered it to happen. However it’s untimely – at greatest – to wed fact 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 right course of subsequent motion.

Proof already well-known demonstrates conclusively that the Cheney-Bush administration violated the Geneva Conventions and dedicated conflict crimes. That this was achieved underneath the colour of “authorized” memos which most probably have been crafted not independently by the Workplace of Authorized Counsel however slightly with the total 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.
