Be CSI an omission or not, examination of those graphics suggests the size of the CSI effect AD1000 to AD2000 amounts to +2 Wm ^ -2 insolation (+0.002 Wm ^ -2 / year) over high northern latitudes during the merry months of April & May and -2 Wm ^ -2 insolation -LRB--0.002 Wm ^ -2 / year) over higher northern latitudes during the jolly months of July & August.

Not exact matches

To achieve these desirable qualities, greenhouse growers in northern latitudes must rely on supplemental lighting from high - pressure sodium lamps during winter months.

During the last deglaciation, and likely also the three previous ones, the onset of warming at both high southern and northern latitudes preceded by several thousand years the first signals of significant sea level increase resulting from the melting of the northern ice sheets linked with the rapid warming at high northern latitudes (Petit et al., 1999; Shackleton, 2000; Pépin et al., 2001).

Another seemingly useful clue is that, during a period of methane doldrums (no rise) from 1999 - 2002, the N / S gradient of methane relaxed a bit [Dlugokencky et al., 2003], suggesting that the doldrum was due to a decline in a methane source in the northern high latitudes.

And for a little historical perspective: «It will without doubt have come to your Lordship's knowledge that a considerable change of climate, inexplicable at present to us, must have taken place in the Circumpolar Regions, by which the severity of the cold that has for centuries past enclosed the seas in the high northern latitudes in an impenetrable barrier of ice has been during the last two years, greatly abated.

Figure 2.24: Variation of winter storm frequency and intensity during the cold season (November - March) for high latitudes (60 - 90 ° N) and mid-latitudes (30 - 60 ° N) of the Northern Hemisphere over the period 1949 - 2010.

The Royal Society ``... a considerable change of climate, inexplicable at present to us, must have taken place in the Circumpolar Regions, by which the severity of the cold that has for centuries past enclosed the seas in the high northern latitudes in an impenetrable barrier of ice has been during the last two years, greatly abated....

Despite the accompanying colder winters, getting melting going during those long hot summers is how we got rid of the ice sheets at high northern latitudes.

It will without doubt have come to your Lordship's knowledge that a considerable change of climate inexplicable at present to us must have taken place in the Circumpolar Regions, by which the severity of the cold that has for centuries past inclosed (sic) the seas in the high northern latitudes in an impenetrable barrier of ice has been during the last two years greatly abated.

It is likely that large rapid decadal temperature changes occurred during the last glacial and its deglaciation (between about 100,000 and 10,000 years ago), particularly in high latitudes of the Northern Hemisphere.

A new study in the Arctic north shows that water at the higher latitudes are undergoing as serious changes as other areas, but they're changing at an even faster rate.Physorg writes that researchers from nine European countries have turned a coal mine village off the coast of Ny - Aalesund, just shy of 750 miles from the North Pole, into a laboratory site during July in a major effort to understand how ocean acidification is altering the northern water.

Hence, atmospheric GEM concentrations inferred from Greenland firn air and global anthropogenic Hg emissions have exhibited consistently similar trends during the most recent decades (Fig. 2), suggesting that the atmospheric reservoir of mercury at mid - and high - northern latitudes has been driven mainly by anthropogenic emissions during the last decades.

Much of the warming seen during DJF over high northern latitudes is strongly controlled by each model's simulation of ice and snow cover during the preindustrial period, and how they respond to a warming climate.

Our ability to place the recent temperature increase in a longer paleoclimate perspective is also hampered by an apparent change in the sensitivity of recent tree - growth to temperature at high northern latitudes where trends in TRW and MXD have been reported to increasingly diverge from the instrumental records during the second half of the twentieth century (Jacoby and D'Arrigo 1995; Briffa et al. 1998a, b; D'Arrigo et al. 2007).

During this period the Northern Hemisphere remained ice - free, and paleobotanical studies show cool - temperate Pliocene floras at high latitudes on Greenland and the Arctic Archipelago.
