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.'"

American markets have no season; if you want a jackfruit, it can and will be delivered more than two thousand miles to you and the ramifications of that is not even a cursory consideration. Drinks are kept cold, constantly. Ice is plentifully and liberally added to nearly any beverage you get. Beer hovers somewhere around the freezing mark. We can do this because the way we approach energy is just as we had in the 50's.

    our rail system is no different than it was in the early 50's. slight modifications have been made to handle larger cargo, but the system runs at around 40 miles per hour and carries only the most cumbersome goods. Cars, Coal, shale oil and natural gas are the chief passengers. toxins too dangerous to transport by semi truck, things like hydrofluoric acid, are also frequently transported. Corridor rail systems used in boston and LA that do in fact transport people are powered exclusively by diesel, as are all our rail systems. We have minimal and fiercely debated electric light rail systems in some cities, and some have transitioned their busses to natural gas, however outside our largest four or five metropolitan areas every transportation request you have will be granted by the automobile.

Tornadoes are way down and have been for several years. We just had a record-setting cold year in the US (with daily cold records outnumber warm records maybe 2 to 1) with a record-setting cold winter. The current projection for midsummer sea ice is pretty close to normal. The antarctic has quietly been setting sea ice records for two or three years running without anyone paying the slightest attention (except maybe when boatloads of tourists travelling there to "document sea ice loss" get trapped for weeks in the ice, the boats that come to rescue them get trapped in the ice, and it takes large amounts of money and risk to rescue them).

    But aside from all of that, the assertion that we could deliver all of the world's current energy requirements at all, with almost unlimited investment, without carbon is almost without foundation. Almost because if we invested sufficiently heavily in nuclear power and successfully developed e.g. LFTR (Thorium) as an alternative nuclear power resource, it is barely possible that with enormous investment and the building of hundreds if not thousands of plants and the extensive mining of e.g. Monazite sand we could make it. Assuming, of course, somebody were willing to foot the bill for the third world and the rapidly developing nations like India and China.

    As for solar, I love it to death, and as time passes and technology develops it might eventually be a prime-time player. In the meantime, it is expensive compared to carbon, useless above a certain latitude, and useless at night. We do not have any mature, cost-effective technology for storing energy from solar to deliver at night, and we are in all probability at least decades away from having one. Wind power is even more problematic -- you can't even be guaranteed of having power during the day, and it has to be stored/buffered on a minute by minute basis as the wind is highly intermittent nearly everywhere. Long range delivery of electricity is also still not feasible, so we cannot generate electricity in Arizona and ship it to Maine, not without a truly monumental investment in e.g. ultra-high voltage trans-continental transmission lines or the development of new technologies. In the meantime, both of these power sources are completely inadequate as standalone energy resources without substantial backing from fuel-burning resources -- either carbon or nuclear. Even things like electric cars, touted as being better than gasoline, suffer from serious energy density storage problems and have pitiful ranges (as well as numerous other issues). Biofuels do better -- I can actually believe that we might manage to break even or win a bit on biofuels within the next decade, especially if new genetically engineered organisms and improved technologies there help out. But not even biofuels are prepared AFAIK to take on the full burden of generating not only automotive power but general electrical demand, and there are major questions about how scalable they will end up being even produced on an industrial scale.

    So precisely how could we eliminate the use of fossil fuels, or carbon based fuels, worldwide, without any negative impact on life style? I track the technologies that are out there pretty closely, and am a physicist (and thereby "probably not an idiot") and I cannot see any possible way we could manage it with a HUGE negative impact as the required technologies simply don't exist yet (and some of the one

    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.
