Sentences with phrase «small changes in the mass»

David Pyle of Oxford University said small changes in the mass of the earth's surface seems to affect volcanic activity in general, not just in places where ice receded after a cold spell.

Not exact matches

The sum total or added knowledge in the sixty years following Cook's voyages had led to a general belief that around the South Pole was a scattered archipelago and not a continental mass, a state of geographical information that was not materially changed until the discovery by Charles Wilkes that after all there is a great Antarctic land, even if it is smaller than the land of legend.

The small increase in the high - dose group did not translate into beneficial effects because authors found no difference between the three study groups for changes in spine, average total - hip, average femoral neck or total - body bone mineral density, trabecular bone score, muscle mass or sit - to - stand tests.

For those who aren't familiar with it, the «tipping point» is a concept from epidemiology (popularized by the best - selling book by Malcolm Gladwell) that suggests that small changes accumulate innocuously until a critical mass is reached, at which point a large - scale, irreversible change occurs in the system under study.

By combining GOCE's high - resolution measurements with information from Grace, scientists can now look at changes in ice mass in small glacial systems — offering even greater insight into the dynamics of Antarctica's different basins.

«What is most interesting is that there are big shifts in the surface mass balance that occur from only very small changes in radiative forcing,» said Ullman, who is in OSU's College of Earth, Ocean, and Atmospheric Sciences.

Consistent with observed changes in surface temperature, there has been an almost worldwide reduction in glacier and small ice cap (not including Antarctica and Greenland) mass and extent in the 20th century; snow cover has decreased in many regions of the Northern Hemisphere; sea ice extents have decreased in the Arctic, particularly in spring and summer (Chapter 4); the oceans are warming; and sea level is rising (Chapter 5).

Making small dietary changes and meeting the recommended 3 servings of dairy per day can significantly aid in building and maintaining a healthy bone mass, leading to improved bone health and prevention of disease such as osteoporosis.

And this is just one element in the sea level rise — small ice caps are melting faster, thermal expansion will increase in line with ocean heat content changes and Antarctic ice sheets are also losing mass.

It would take a greater catastrophe to move the masses in such a way as you laid out, smaller changes are adaptable.

As for how this could be — and in light of the findings of the references listed above — Rankl et al. reasoned that «considering increasing precipitation in winter and decreasing summer mean and minimum temperatures across the upper Indus Basin since the 1960s,» plus the «short response times of small glaciers,» it is only logical to conclude that these facts «suggest a shift from negative to balanced or positive mass budgets in the 1980s or 1990s or even earlier, induced by changing climatic conditions since the 1960s.»

The ice mass loss observed in this research was a change from the trend of losing 113 ± 17 gigatons per year during the 1990s, but was smaller than some other recent estimates (Luthcke et al. 2006).

There was a small consistent change in mass balance when either 194 points / km2 or 388 points / km2 (169 - 338 measurment points) are utilized, in comparison to the smaller measurement densities.

Once I do some double checking, you should be able to «see» how the slow and relatively small changes in SST are amplified by the lower capacity land masses and the atmospheric effect, to produce larger temperature swings with the same energy.

Striking changes in salinity are found from the surface to the bottom in the northern North Atlantic near water mass formation sites that fill the water column (Section 5.3.2); bottom changes elsewhere are small, being most prevalent at the under - sampled southern ends of both sections.

So, if these currents have mass, and these currents are looping through a periodically changing barycenter, all that is needed to affect something else in the sun — and whether that symptom of the change is a change in sunspot number, or sunspot cycle intensity, or change in the sun's net magnetic field, or corona «height», or ejected masses, or whatever is a small change in the position of the barycenter.

In the final analysis we are arguing about a temperature record made by volunteers with little oversight over many generations on continents where a truly massive amount of land use change due to industrialization and agriculture and where said land mass is but a small fraction of the globe's surface one might wonder why we bother with it.

The limited resolution of GRACE affects the uncertainty of total mass loss to a smaller degree; we illustrate the «real» sources of mass changes by including satellite altimetry elevation change results in a joint inversion with GRACE, showing that mass change occurs primarily associated with major outlet glaciers, as well as a narrow coastal band.

Perhaps we spent too much time watching Monty Python movies and singing «Always look on the bright side of life,» but we thought that there was perhaps a good side to high gas prices, that people would change their habits to adapt, and suddenly the world would be filled with small efficient cars, lots of mass transit, all food would be locally grown and every new home would be New Urbanist or multifamily, mainly in reborn Buffaloes or Detroits with a bicycle in every garage and an organic chicken in every pot.

For crying out loud the gravitional mass of Jupiter makes small changes in the eccentricy of the earth's and depending on whether eccentricity max / min is in or out of phase with earth axial tilt min / max spells the difference between glaciers a mile thick covering everything north of Washington, DC and whether grass is able to sprout in Montreal.

To quote from AR5 WG1: «While surface melting will remain small, an increase in snowfall on the Antarctic ice sheet is expected (medium confidence), resulting in a negative contribution to future sea level from changes in surface mass balance.»

«Scientists can now look at changes in ice mass in small glacial systems,» ESA said.
