Sentences with phrase «orbit changed such»

Michael, think about what would happen as small variations in earth's orbit changed such that the northern polar region received increasingly less sunlight each summer, preventing all of the previous year's snowfall from melting.

Holman says the changes in the transit times of these planets were enhanced by the fact that one of the planets orbits the star in almost exactly half of the time that it takes the other, as such «orbital resonances» increase their gravitational interaction.

John Ahlers at the University of Idaho in Moscow wondered how gravity - darkening might change the seasons on a planet orbiting such a squished star.

Objects with chaotic rotations (such as Hyperion) are also problematic, as their synchronous orbits keep changing unpredictably.

Black hole hair would change how such objects orbit near the hole, and these changes could be detectable by telescopes that will come online within the next decade.

Once retrieved the tug would use the boulder's extra mass to act as a «gravity tractor,» orbiting the asteroid in such a way as to subtly change the asteroid's trajectory.

«It is true that there are other factors (such as volcanism, the changes in the orbit and the axis of the Earth, the solar cycle), but numerous scientific studies indicate that most of the global warming in recent decades is due to the large concentration of greenhouse gases (carbon dioxide, methane, nitrogen oxide and others) mainly emitted due to human activity.»

Confirming previous modelling of the Alpha Centauri system, the RECONS astronomers found that Alpha Centauri A and B orbit in such a way that when the light and heat of the two stars was combined, neither star in the innermost AB system significantly changed the size of their respective habitable zones, regardless of where each was currently located in its orbit.

There is evidence that Earth has gone through at least one globally frozen, «snowball» state in the last billion years, which i... ▽ More Although the Earth's orbit is never far from circular, terrestrial planets around other stars might experience substantial changes in eccentricity that could lead to climate changes, including possible «phase transitions» such as the snowball transition (or its opposite).

The comet appears to have undergone visible changes, including the changes in the size and number of surface features such as smooth patches, pits, and craters, and the loss of ice vaporized by the Sun or blasted off its surface by the Solar Wind into its tail as well as failing back on the object like snow, so that it appears to shrink, on average, by 25 to 50 centimeters (9.2 to 19.7 inches) with each orbit around the Sun.

Confirming previous modelling of multiple star systems with relatively wide orbits such as the Alpha Centauri system, the RECONS astronomers found that Alpha Centauri A and B orbit in such a way that when the light and heat of the two stars was combined, neither star in the innermost AB system significantly changed the size of their respective habitable zones, regardless of where each was currently located in its orbit.

It has passed safely before and scientists have calculated at least a couple of centuries out that, even with the slight changes that can occur in the orbits of such objects, this particular space rock won't add to the planet's pockmarks.

It is true that there are other factors (such as volcanism, the changes in the orbit and the axis of the Earth, the solar cycle), but numerous scientific studies indicate that most of the global warming in recent decades it is due to the large concentration of greenhouse gases (carbon dioxide, methane, nitrogen oxide and others) mainly emitted due to human activity.

He also claimed that «other factors such as sun spot cycles and oscillations in the Earth's orbit are at least as important for climate change as this trace gas — which, far from being pollution, is actually essential for life to exist.»

For example, some people consider astrophysical factors such as changes of the Sun in its orbit around the Milky Way, some are considering the implications of magnetism, and others changes in the Length of Daylight (LOD).

Some apparent problems with the predictions of climate models, for example, have actually turned out to be due to problems with real - world data caused by the failure to correct for factors such as the gradual changes in orbits of satellites.

If you studied the effects on climate of mountains formation and the Miin your geology modules, you shoule be aware that the variations of CO2 during Earth's geological record were all caused by rapid temperature changes by means other than CO2 variations, such as cycles in the Earth's orbit or geological processes that created large mountain ranges.

Such rapid change — much faster and larger than slow changes in orbit or solar intensity — is the marker for internal variability.

The answer is that CO2 is only one of several factors that influence temperature, such as volcanic eruptions, solar variability, sulfur dioxide emissions (see Figure 1), and small changes in the earth's orbit.

Since such models can not account for the climate system's apparent sensitivity to small perturbations in solar energy apparently brought about by the very long term changes in the Earth's orbit about the Sun, they may also underestimate climate sensitivity to energy output fluctuations caused by solar activity, even during the eleven - year Schwabe cycle.

Before humans, changes in climate resulted entirely from natural causes such as changes in Earth's orbit, changes in solar activity, or volcanic eruptions.

The ocean surface is not level, but «lumpy» for various reasons; local gravity, density (temperature, salinity), air pressure, currents, wind, outflow from rivers, rotation of the Earth, tides, changes in Moon's orbit, ocean cycles such as the Pacific Oscillation, North Atlantic Oscillation, and a few others I can't remember just now.

Professor Plimer said climate change was caused by natural events such as volcanic eruptions, the shifting of the Earth's orbit and cosmic radiation.

The rock record reveals that such rainfall changes occur at the same time as general alterations in the relative strength of sunlight hitting the planet thanks to periodic shifts in Earth's orbit, known as Milankovitch cycles.

While the Earth's atmosphere has seen higher levels of carbon dioxide than it does now, as well as higher temperatures and far greater sea levels, those instances were due to natural drivers of climate change, such as periodic variations in the planet's orbit and in solar energy output.

There are also problems with the MSU / AMSU warm targets, such as the effects of moving from from the sunlit side to the night side during each orbit and changes in LECT, etc..
