Sentences with phrase «by decreasing solar activity»

«The stagnation of temperature since 1998 was caused by decreasing solar activity since 1998,» wrote Jürgen Lange Heine, a physicist with the German - based European Institute for Climate and Energy (EIKE).

Not exact matches

Sunspot activity, which ebbs and flows on an 11 - year cycle, decreases the cosmic ray flux by periodically increasing the solar wind — a stream of charged particles emitted by the sun.

«It could therefore be concluded that both the decreasing correlation between sunspot number and geomagnetic activity, and the deviation of the global temperature temperature long - term trend from solar activity as expressed by the sunspot index are due to the increased number of high speed streams of solar wind on the decreasing phase and the minimum of sunspot in the last decade.»

The correlation between the two quantities is 0.85 with p < 0.01 for the whole period studied.It could therefore be concluded that both the decreasing correlation between sunspot number and geomagnetic activity, and the deviation of the global temperature long - term trend from solar activity as expressed by sunspot index are due to the increased number of high - speed streams of solar wind on the declining phase and in the minimum of sunspot cycle in the last decades.»

Such lulls in solar activity, which can cause the total amount of energy given off by the Sun to decrease by about a tenth of a percent, typically spur surface temperature to dip slightly.

-- August 16, 2008 — Excerpt: An expert from the National Autonomous University of Mexico predicted that in about ten years the Earth will enter a «little ice age» which will last from 60 to 80 years and may be caused by the decrease in solar activity.

Note, for example, how the temperature trend in the first decade of the 21st century was generally flat because an upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures continued to rise).»

For example, the scientific explanation that temperatures have not risen since 2001 is because an «upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures continued to rise)».

However, so far, they have only used those reconstructions which (a) suggested an early 20th century increase followed by a decrease, or (b) suggested there has been almost no change in solar activity since the 19th century.

Here, we explore possible impacts through two experiments designed to bracket uncertainty in ultraviolet irradiance in a scenario in which future solar activity decreases to Maunder Minimum - like conditions by 2050.

All of this will be over by 2015, when the records of 2010 and 1998 will have been obliterated by increased solar activity, ENSO and decreased albedo as we go into virtually ice free arctic summers, oh and increased GHG concentrations of course.

The ozone process is complex and little understood, but recent finds by Haigh are showing quantities of ozone can increase above 45 km and decrease below during times of weak solar activity, which is no doubt brought about by the chemical changes that fluctuating EUV / FUV brings along.

Decrease of solar activity is harbinger of 1.5 deg C drop by 2020 (3X the rise of the last Century) Warming greatest in past decade Argentina November (2007) frost devastates agriculture.
