That's going to be a very long list. - Or did you mean to title it "Actual effects" - as the two articles suggest?

I'm a bit uncoherent today, so I don't touch the page but just toss in here some collected stuff.

Another already actual effect: **Expansion of the tropical belt**

[Tropical zone expanding due to climate change: study]( (2009)

>Researchers at James Cook University concluded the tropics had widened by up to 500 kilometres (310 miles) in the past 25 years after examining 70 peer-reviewed scientific articles.


>Professor Steve Turton said that meant the subtropical arid zone which borders the tropics was being pushed into temperate areas, with potentially devastating consequences.

> "Such areas include heavily-populated regions of southern Australia, southern Africa, the southern Europe-Mediterranean-Middle East region, the south-western United States, northern Mexico, and southern South America," he said.

> "All of (them) are predicted to experience severe drying.

> "If the dry subtropics expand into these regions, the consequences could be devastating for water resources, natural ecosystems and agriculture, with potentially cascading environmental, social and health implications."

>Climate change is having a dramatic impact on the tropics by pushing their boundaries towards the poles at an unprecedented rate not foreseen by computer models, which had predicted this sort of poleward movement only by the end of the century.


>"Several lines of evidence show that, during the past few decades, the tropical belt has expanded. This expansion has potentially important implications for subtropical societies and may lead to profound changes to the global climate system," the scientists say in their study published online in the journal Nature Geoscience.


>They are particularly concerned about the poleward movement of subtropical dry belts that could affect water supplies and agriculture over vast areas of the Mediterranean, the south-western United States, northern Mexico, southern Australia, southern Africa and parts of South America.

Actual **Vegetation die-off**: [Regional vegetation die-off in response to global-change-type drought](


>Collectively, these observations suggest that the mortality response to the recent drought was greater in magnitude and extent than the mortality response to the 1950s drought. The warmer temperatures associated with the recent drought would have increased the energy load and water stress demands on the trees and may account for the apparently greater resulting mortality.

> The cessation of drought conditions may be insufficient for reestablishment of P. edulis and associated plant species, as documented for landscape response of Pinus ponderosa after the 1950s drought (5). Such rapid shifts in vegetation may represent abrupt, rapid, and persistent shifts in not only ecotones, but also in dominant vegetation cover and associated ecosystem process (5, 7-8).

Here's a [cut-out]( of their fig. 1 illustrating the difference to the 1950 type drought.
