What effect will climate change have on the economy?

From a recent report by the Union of Concerned Scientists:

Agriculture: By late-century under the higher-emissions scenario, heat stress in cows is projected to cut milk production across much of the region by 5 to 20 percent in certain months, with the greatest losses in the key dairy state of Pennsylvania. Parts of the Northeast are projected to become unsuitable for growing certain popular varieties of apples, blueberries, and cranberries by mid-century, since they require long winter-chill periods to produce fruit. Meanwhile, weed problems and pest-related damage are likely to escalate, increasing pressures on farmers to use more herbicides and pesticides. By contrast, changes expected under the lower-emissions scenario are generally much less extensive.

Marine fisheries: As ocean temperatures continue to rise, the range of suitable habitat in the Northeast for many fish and shellfish species such as cod and lobster is projected to shift northward. Cod are expected to disappear from the region's waters south of Cape Cod during this century, under either emissions scenario. With higher emissions, the renowned fishing grounds of Georges Bank will likely lose its cod stocks. The lobster populations in Long Island Sound and the nearshore waters off Rhode Island and south of Cape Cod are expected to be lost by mid-century under either scenario.

Winter recreation and tourism: Under the higher-emissions scenario, only western Maine is projected to retain a reliable ski season by the end of the century, and only northern New Hampshire would support a snowmobiling season longer than two months. Under the lower-emissions scenario, reliable ski seasons can be expected through this century in the North Country of New York and parts of Vermont and New Hampshire, in addition to western Maine.

Richard Linden, enviromental journalist was asked...

Are we prepared for sudden environmental changes?
If climate change was gradual and incremental, societies could deal with it and adjust their behavior to the risk. But if it’s rapid and extreme, there’s no society on earth that can deal with it. In fact, economists can’t even model the impact. Most of the economic modeling you see about climate change is built on a gradual and incremental model, which doesn’t exist in the environmental record. Even an economy that could absorb the cost of Katrina would have difficulty with a cluster of intense weather shocks—droughts, floods and ice storms and hurricanes.

issue prior to revisions:

I like the revision -- "Will climate change affect the economy?"

But, I think the stands should go back to Positively, Negatively and No Effect. So I guess I think it should be "How will climate change affect the economy?"

This looks good to me.

great.  Many are hesitant to act abruptly in reaction to global warming out of fear that it could destroy the economy.  I would say positively. 

I suppose that "climate change" makes it more neutral, but it seems rather vague. (Would anyone say no to this?)

issue revision:

How will a shift towards more renewable energy affect the economy?

-positively
-negatively
-no effect

Renewables could supply one-quarter of US energy by 2025, with no harm to economy, a study says.

You're a frame artist!  Ahah.

positively

negatively

no impact

How will global warming effect the economy?

this might be terrible bc it assumes climate change exists.  let me know how i can fix it.
