Sea level rose 200 mm (~8 in) from 1900 to 2000. It's expected to rise more than twice that much by 2100. 800 mm is the number I've heard lately.
Also, apparently the SLR from thermal expansion has been about equal to that from ice sheet and glacier melt but thermal expansion is expected to contribute more than half of it in the current century.
Never the less if you compare the cost of electricity from public power supplies to private power companies the cost from public power is nearly always cheaper.
Actually, if paeleoclimate evidence is to be believed the maximum temperatures were reached about 8,000 years ago and has been slowly declining since then until recently.
Of course, a study of terran evolution would quickly show that icy polar caps is not the average behavior for earth.
Of course a study of human evolution would show that homo sapiens has not existed on the planet when were not icy polar caps. We're not evolved for your significantly warmer planet. (But humans are very adaptable so we'd probably be able to survive on it.)
At no time since the genus homo evolved has the CO2 level of the atmosphere been higher than about 300 ppm until now. During the Little Ice Age (about 1500-1850) the CO2 level was about 280 ppm. The last time CO2 levels are thought to be higher than they are today was over 15 million years ago. Yes, Mother Nature will find a new equilibrium but the transition to that new equilibrium may not be pleasant for those going through it.
Three fourths of the big power transmission lines in the Northwest are run by the Bonneville Power Administration (similar to the TVA) and aren't subject to the whims of the free market. It's one thing that keeps our electricity costs lower here.
The reservoirs along the Columbia River between Oregon and Washington are what they call Run-of-the-river reservoirs that don't have a significant amount of storage relative to the flow of the river. When they're not generating electricity the water is just spilled. Most of the run-of-the-river power stations on this list are located on the Lower Columbia or its tributary the Snake River.
Actually, a large chunk of sea level rise so far is simply because of water expanding as it heats up. It think the rise from expansion is greater than the rise from land based ice melting so far. That won't be true forever though.
Well, actually we do need to stop burning fossil fuels altogether. But a realistic look at it says it's going to take 30 or 40 years to get there at best.
Radio waves don't penetrate the soil much. Unless the Faraday cage was tapered down to barely big enough to go around the trunk as it comes out of the ground I imagine it would shield the root area reasonably well anyway.
The vast majority of the Sun's EM radiation is in the visible and ultraviolet range. The worst of the UV is intercepted by the ozone layer and life on Earth is well adapted to the visible light range. It would be interesting to compare the relative strength at ground level of the Sun's radio frequency emissions to those from terrestrial sources.
Temperature variations may come from a variety of causes including astronomical causes and no climate researcher will tell you anything different. However orbital changes occur over thousands of years and are a minuscule factor in the current situation. CO2 levels are both a cause and an effect (forcing and feedback in climatology speak) of temperature variations, it's not an either or thing.
Well, the whole point of "An Inconvenient Truth" was to publicize the issue. I guess you'd have to say it did a decent job.
The rhetoric has been flying for well over a decade already, very little of it favorable to the "anti global warming" crowd. How long should we wait to act?
I believe the research funding Dr. Mann brings to Penn State is less than 2% of its total research grants. Do you seriously think they would jeopardize the other 98%+, risking their reputation for good science to protect Mann and his research? Not likely.
There are many things beyond our control which influence climate change.
And there are some things we can control that influence climate change, greenhouse gas emissions, deforestation and land use changes for example. It's probably to our benefit to do what we can about the things we can control.

Don't Californicate Oregon!

As I mentioned above the reservoirs along the Columbia are run-of-the-river and as such don't have a lot of storage capacity.

Heppner has less than 1,500 population. It's more like a neighborhood in most towns.
Why is the fossil fuel industry so heavily subsidized? They get far more subsidies than green energy, at least in the US.
For most of Earth's history there were no humans. Maybe we are the anomaly.
BTW, there have always been polar ice caps during the existence of humans on the planet.
Of course the answer to the mercury problem in fish is also part of the answer for AGW. Stop burning coal.

Wait! I thought it was the humans that got infected with malaria and the mosquitoes were just carriers.
Iran is another country we could turn into a sheet of radioactive glass long before they could build enough nuclear weapons to seriously threaten US.
Even more apropos to this subject is Heinlein's The Roads Must Roll.

They only paint that picture for someone preprogramed to believe it.
