That is the ultimate version of Evening Owls, a themed open thread
that has appeared at Every 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 degree rise in North America and power fish to maneuver farther north:

Because the 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 position 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 not less than the final 1,000 years, new analysis reveals.

Along with other studies exhibiting that world warming is driving the weakening, the brand new findings counsel that the circulation will lose much more power within the many years forward. That might 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 world warming, the Gulf Stream System will weaken additional, by 34 to 45 p.c by 2100 in accordance with the newest 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 essential to think about how the adjustments will have an effect on ocean ecosystems, he mentioned. Among the currents related to the overturning circulation are essential for dispersing coral larvae, and since adjustments to the present additionally have an effect on temperature and salinity, they’re more likely 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 concerning the connection between poverty and environmental degradation, and constructing that message on the grassroots degree. 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 atmosphere (which will not be what’s deemed “globally worthwhile” by supporters within the world north) or the problem poor folks face when attempting to steadiness rapid must feed a household and the medium and long-term want to guard environmental sources. When a toddler is ravenous, a household will not be in a position to consider long-term sustainability or injury to ecosystems that assist endangered species. You may assist the environmental motion see that dilemma so we will come collectively round world and native options that tackle brief time period challenges as properly.”

BLAST FROM THE PAST

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

To make sure, the reality should be uncovered. Or, somewhat, we should add to the truths we already learn 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 finally 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 battle crimes. That this was achieved beneath the colour of “authorized” memos which probably have been crafted not independently by the Workplace of Authorized Counsel however somewhat 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.
