Observations that students in the middle of the school year are encountering items that reflect end of the year skills does not indicate a failure in alignment to the standard, but rather demonstrates clear alignment with the standard and indicates the student's current relative mastery of all the skills to be learned.
The impacts on teacher effectiveness and placement are inconclusive during the first couple of years of study; however, majorities of teachers have indicated that the feedback they received, especially from classroom observations, has prompted them to make changes in their practice.
Our analysis of observations from four years of field experiments indicates that seasonal ice undergoes an albedo evolution with seven phases; cold snow, melting snow, pond formation, pond drainage, pond evolution, open water, and freezeup.
Sunspot observations for the last 400 years clearly indicate that current levels of solar activity are very different from the state of the sun during the Maunder minimum (from approx. 1645 to 1715 AD) where almost no sunspots could be observed.
The combination of observation - based estimates... with NCAR CSM1.4 - carbon model projection indicates that 10 % of the surface water along the investigated Arctic transect will become undersaturated for at least one month of the year when atmospheric CO2 exceeds 409 ppm.
The models and observations both also indicate that the amplitude of interannual variability about these longer - term trends is quite large, making it foolhardy, at best, to try to estimate the slope of anthropogenic warming from a few years of data (as you seem to advocate).
Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.
«Satellite observations, which began in 1993, indicate that the rate of sea level rise has held fairly steady at about 3 millimeters per year.
I do think AGW would have been right up his alley had he lived another 10 - 20 years, but his revival on the Kuwait fires indicates that eventually he'd be capable of recognizing that «the most precise observations» demolish his «dearest illusions».
Both the observations of mass balance and the estimates based on temperature changes (Table 11.4) indicate a reduction of mass of glaciers and ice caps in the recent past, giving a contribution to global - average sea level of 0.2 to 0.4 mm / yr over the last hundred years.
This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34
Global sea levels have been rising since the glacial maximum of the last ice age some 18,000 years ago, but observations indicate that the rate of sea level rise is not accelerating and may even be decelerating.
«My interaction (over the years) with a broad segment of AMS members (that I have met as a result of my seasonal hurricane forecasting and other activities) who have spent a sizable portion of their careers down in the meteorological trenches of observations and forecasting, have indicated that a majority of them do not agree that humans are the primary cause of global warming.
