Sentences with phrase «radiation levels over»

March 11, 2018: On the 7th Anniversary of Fukushima Disaster, It's Still a Long Way From Over 7 years on, the decontamination process scheduled for March 2018 has been suspended due to «extremely high» radiation levels (one hour, you're dead).

What's next: Weber and Gao and their colleagues hope to apply the work to more complex materials to look at how trapped electrons affect the way defects move and interact with each other when the material is exposed to more than one blast of radiation over longer times in much larger systems and at higher levels of radiation.

Microwaves do, make no mistake, emit radiation, and the FDA has established what it considers «safe» levels for microwaves: over the machine's «lifetime» the allowable level is «5 milliwatts of microwave radiation per square centimeter... approximately 2 inches from the oven surface.»

UV radiation can decrease hyaluronic acid levels in the skin, over decades of sun exposure.

Miami seems to fall in a nice zone where you still get the heat and humidity water and fat loss benefits of hot weather, but they are turned up a notch over, say, NY, with the almost tropical level UV radiation on top of it.

But a change of -1.7 % in (high level) clouds over 1 decade caused a change of 1.2 W / m2 in reflected SW and ~ 3 W / m2 more IR radiation to space over the 30N / S band.

Trends as a function of CSD, Saturation: If the temperature varies monotonically over the distance from which most of the radiation reaching that level is emitted, then increasing the CSD will bring the upward and downward fluxes and intensities (at a given angle) toward the same value, reducing the net intensities and fluxes, until eventually they approach zero (or a nonzero saturation value at TOA).

All Levels of Radiation Confirmed to Cause Cancer The National Academies of Science has released an over 700 - page report on the risks from ionizing radiation.

Since the 1980s the most severe ozone layer depletion has been regularly observed over Antarctica during spring, when ozone levels drop by over 95 % and UV radiation reaching Earth's surface increases substantially.

Even though radiation from the troposphere is much slower, the heat is much more widely distributed; a lot of it is moved over what would have been much cooler ground — it isn't just low level atmospheric heat transport that matters.

Global sfc temperatures declined (or leveled depending on series) over 1950s, 60s and 70s due to declining sfc solar radiation (that temperature decline / leveling unexplained by CO2).

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

[44] a reduction of 1/7 of the water vapour content of the air near 300 mbar pushes down by a factor 1 / (1-1/7) 4.7 = 1.03 the P80 % level and the P80 % temperature increases by a factor 1.030.19 = 1.006 that is by about 1.5 K for the radiation temperature over the far infrared spectral range

While actual scientists are trying to piece together every little part of an otherwise almost un-piecable long term chaotic and variable system in response now to a massive increase in net lower atmospheric energy absorption and re radiation, Curry is busy — much like most of the comments on this site most of the time — trying to come up with or re-post every possible argument under the sun to all but argue against the basic concept that radically altering the atmosphere on a multi million year basis is going to affect the net energy balance of earth, which over time is going to translate into a very different climate (and ocean level) than the one we've comfortably come to rely on.
