Sentences with phrase «pattern of warming remained»

For instance, Mojib Latif of the Leibniz Institute of Marine Sciences in Germany and his colleagues published a paper in 2008 that suggested ocean circulation patterns might cause a period of cooling in parts of the Northern Hemisphere, even though the long - term pattern of warming remained in effect.

James E. Hansen, the head of Goddard and an outspoken campaigner for prompt cuts in greenhouse - gas emissions, explained that the decades - long global warming trend and patterns of warming remain consistent with a growing influence on climate from the planet's building blanket of heat - trapping greenhouse gases.

Not exact matches

Current work1 has provided evidence of the increase in frequency and intensity of winter storms, with the storm tracks shifting poleward, 2,3 but some areas have experienced a decrease in winter storm frequency.4 Although there are some indications of increased blocking (a large - scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere, 5 the assessment and attribution of trends in blocking remain an active research area.6 Some recent research has provided insight into the connection of global warming to tornadoes and severe thunderstorms.7, 8

All these stations indicate the same pattern of changes in annual mean temperature: a warm 1930s, a cooling until around 1970, and thereafter a warming, although the temperature remains slightly below the level of the late 1930s.

Wind and ocean circulation patterns are conspiring with a warmer climate to reduce the amount of year - round (multi-year) ice, transforming the remaining ice into a younger, thinner version of its old self.

There is new information that lack of sea ice causes storms to produce larger waves and more coastal erosion.5 An additional contributing factor is that coastal bluffs that were «cemented» by permafrost are beginning to thaw in response to warmer air and ocean waters, and are therefore more vulnerable to erosion.22 Standard defensive adaptation strategies to protect coastal communities from erosion such as use of rock walls, sandbags, and riprap have been largely unsuccessful.23 There remains considerable uncertainty, however, about the spatial patterns of future coastal erosion.

In the report, the panel emphasized that the significant remaining uncertainties about climate patterns over the last 2,000 years did not weaken the scientific case that the current warming trend was caused mainly by people, through the buildup of heat - trapping greenhouse gases in the atmosphere.

USA Today «s house editorial today bemoans the fact that Climategate «gives ammunitiion to the skeptics,» but concludes that «the overwhelming scientific consensus remains that the Earth is warming, largely because of human activity, with potentially calamitous consequences involving melting ice caps, rising sea levels and shifting agricultural patterns.»
