US Climate Report Says Global Warming Impact Already Severe
Hugh Pickens DOT Com writes: "Darryl Fears reports in the Washington Post on the U.S. government's newest national assessment of climate change. It says Americans are already feeling the effects of global warming. The assessment carves the nation into sections and examines the impacts: More sea-level rise, flooding, storm surge, precipitation and heat waves in the Northeast; frequent water shortages and hurricanes in the Southeast and Caribbean; more drought and wildfires in the Southwest. 'Residents of some coastal cities see their streets flood more regularly during storms and high tides. Inland cities near large rivers also experience more flooding, especially in the Midwest and Northeast. Insurance rates are rising in some vulnerable locations, and insurance is no longer available in others. Hotter and drier weather and earlier snow melt mean that wildfires in the West start earlier in the spring, last later into the fall, and burn more acreage. In Arctic Alaska, the summer sea ice that once protected the coasts has receded, and autumn storms now cause more erosion, threatening many communities with relocation.' The report concludes that over recent decades, climate science has advanced significantly and that increased scrutiny has led to increased certainty that we are now seeing impacts associated with human-induced climate change. 'What is new over the last decade is that we know with increasing certainty that climate change is happening now. While scientists continue to refine projections of the future, observations unequivocally show that climate is changing and that the warming of the past 50 years is primarily due to human-induced emissions of heat-trapping gases.'"
No. It's not even that.
The really big problem is, "Okay. It's happening. Now what do we actually DO about it?"
Right there the knives start coming out. Because everyone has a different idea of what should happen.
And there are very few concrete plans, based on actual, proven science.
Most are just variations on "lets tack on a bunch of fines and taxes to make doing certain things unpopular". Which doesn't ACTUALLY address the problem.
Then you have all the people proposing stuff like carbon sequestration through iron doping of algae and all sorts of unproven schemes based on pseudoscience.
Not to mention the fact that we STILL don't have a computer simulation that ACCURATELY models the phenomenon. In short, we can't even properly quantify THE PROBLEM. How the hell are we supposed to come up with a "solution"?
On top of that, everyone in the US could stop producing greenhouse gasses RIGHT NOW, and it wouldn't do a damn thing. Because everyone else is still putting the stuff out. SPECIFICALLY China. Unless we have government buy-in representing the majority of the world's population all that's happening is that we're trading one set of bad actors for another.
And everyone's so precondition to fight over the smallest detail on this that I honestly feel that nothing will ever TRULY be done about it.
Not through lack of care for the long term. But over-abundance of inflexible actors working at cross purposes.

THANK GOD!!!
Fascinating. While I can't comment on all of these points, I did a bit of searching regarding the second LINK about global sea ice: That graph shows the global sea ice area, not the volume. The area slightly increased while the volume has steadily gone down over the same period of time.
This is what makes it impossible for the armchair scientist to understand this. Inevitably, someone will reply telling me why my link is a bunch of dumbutts and how that graph is irrelevant, we should be looking at something else.
So if you and your denialist friends want a seat at the table and want your ideas to be heard, then by all means, bring your extrapolations to the table, if indeed, you have any.
The Arctic sea ice has melted much faster than anyone was predicting just a decade ago. Ice, aerosols, and cloud cover are not very well understood, when you get a bunch of experts together to agree on a statement about those things in a report like the IPCC, the statement is almost certainly going to be conservative. What has changed recently is our ability to measure the changes in the ice mass of the Antarctic and Greenland ice caps to a high level of precision using the GRACE satellite. It doesn't really help scientists make better predictions but it does provide a better test, and allow them to make more confident statements about what is happening now.
A silver lining? - I heard what could be considered good news to everyone (except coal barons). Here in Oz we're busily industrialising the great barrier reef by building a controversial coal mine and the largest coal port in the world. The multi-nationals who were behind the project (BHP, Rio, some banks,..) have all walked away from the project. It's now been reported (on a local business show) that the mine will probably not have the customers in India it expects. Why? - Because wind and solar are now roughly at parity price with imported coal in India and prices are dropping at a rate such that in 2-3yrs time renewables in India will be 10% cheaper than imported Aussie coal. What's is sounding even better is that coal exports have dropped significantly in price since the project was announced and yet it is still neck-to-neck with the price of renewables in India.
If those reports are not a gross exaggeration then it looks like some developing nations really will leapfrog the west and go straight to renewables.
And did you exchange a walk on part in the war for a lead role in a cage? - Pink Floyd.
