Sentences with phrase «orbital changes»

The change in water vapour content will reinforce the warming from orbital change until cloud increases and sets in the negative feedback.

The data show that the sun's variations have been small over the times we care about, the climate responds to variations in sunshine caused by orbital changes, but these are slow.

To compensate for this and other orbital changes a series of adjustments must be applied to the data.

I could go through a dozen... examples: the skill associated with solar cycles, changing the ozone in the stratosphere; the skill associated with orbital changes over 6,000 years.

It made a big difference when only solar orbital changes did anything.

That means the tip is particularly good at mapping out the «nodes» or places where the molecule's orbital changes sign.

The effect of these small orbital changes was amplified by positive feedbacks, such as changes in greenhouse gas levels.

We're told that in the depths of an ice age orbital changes provide a small forcing which warms the planet a tad, causing natural systems to release a small amount of CO2.

The research team now plans to apply their method to the study of deep - sea temperatures elsewhere to investigate how orbital changes affected the climate in different parts of the world.

This positive feedback is necessary to trigger the shifts between glacials and interglacials as the effect of orbital changes is too weak to cause such variation.

> More sunshine from orbital changes produces warming.

Therefore, it would be impossible to attribute any particular orbital change in the future to Deep Impact.

In a substantive sense, because orbital changes have different effects on NH -LSB-...]

A more pronounced orbital change would confound the accuracy of the pulsar timing experiment.

But subsequent collisions, «weathering» from space radiation, and ongoing orbital changes have erased most traces of their ancestry.

The answer, according to theorists, is planetary migration: dramatic orbital changes due to the gravitational interaction of the young giant planet with the remains of the disk, or mutual interactions between planets.

The observed orbital changes took place in the southern components of the system, displaced from the visible star by about one hundred times the distance between the Sun and the Earth.

It seems clear that when something like a change in the sun warms up the Earth, or the Earth's orbital changes warm it up, that's followed by an increase in carbon dioxide released.

Since we know by now that the lunar orbital changes are a driver of tidal forces and thus should not be surprised to find this cycle appearing in various climate records, including the THC (and the AMOC).

Climate science «consensus» claims that spring will arrive this year and there is some kind of «theory» involving orbital changes that explains that.

Glacial periods during the 100,000 - year cycles have been characterised by a very slow build - up of ice which took thousands of years, the result of ice volume responding to orbital change far more slowly than the ocean temperatures reacted.

Some may object that ice - core and sediment - core records are often «tuned» to orbital variations, i.e., the timing is adjusted to match orbital changes.

All this drove home that it scarcely mattered which came first, for the chief effect of the Milankovitch - cycle orbital changes was to initiate a powerful feedback loop.

We know how the planets behave in relation to the sun and to each other today, but venturing millions or billions of years into the past, it can be tricky to figure out what orbital changes may have impacted the Earth's climate.

(The modern view has glaciation initiated by cyclical orbital changes and amplified by a strong CO2 feedback.)

Though Milan Milankovitch would not perform his definitive calculations of the Earth's orbital cycles for three decades yet, the Serb was not the first to consider the effects of cyclic orbital changes.

The albedo and CO2 feedbacks amplified weak orbital forcings, the feedbacks necessarily changing slowly over millennia, at the pace of orbital changes.

Deep - sea cores show a dominating influence from 100,000 - year Milankovitch orbital changes, emphasizing the role of feedbacks.

[Response: the Milankovitch timescale is long and the forcing barely varies due to orbital changes over 100 years so no, they aren't included (they would be for people modelling the last glacial maximum); solar forcing is modelled by change in total solar irradiance (probably as a total number; not sure if changes at different wavelengths are included)-- William]

These are thought to be driven by the large regional changes in insolation driven by orbital changes.

«We know that the only thing changing in the Northern Hemisphere [20,000 years ago] were these orbital changes» that affect the amount of sunlight striking the far north, explains geologist Peter Clark of Oregon State University, who guided Shakun's research.

Scientists knew about the warming effects of greenhouse gases, but proponents of global cooling argued that greenhouse warming would be more than offset by Earth's orbital changes.

In other words, if you argue that the Earth has a low climate sensitivity to CO2, you are also arguing for a low climate sensitivity to other influences such as solar irradiance, orbital changes, and volcanic emissions.

So far as I can see, he could be right about that, without being right about the long - term / Earth System climate sensitivity being as high as 6 degrees C. He's suggesting that previous ice - sheet melting episodes were slow because the forcing due to orbital change was slow, not due to inherent inertia, and that recent observation suggests ice - sheets can melt much faster if the forcing is faster.

As better methods to adjust for biases in instruments and orbital changes have been developed, the differences between the surface temperature record and the troposphere have steadily decreased.
