Sentences with phrase «variation over the planet»

They could not determine the variation over the planet because of poor signal and spatial resolution.

Not exact matches

The planet itself was found over a series of nights from January 19 to March 31, 2016, during which Proxima was monitored closely for subtle variations on the European Southern Observatory's HARPS instrument.

Thus, the observed variations of methane levels over the planet are puzzling.

The presence of a second, non-transiting planet was inferred from the transit time variations (TTVs) of Kepler - 19b, over 8 quarters of Kepler photometry, although neither mas... ▽ More We report a detailed characterization of the Kepler - 19 system.

The presence of a second, non-transiting planet was inferred from the transit time variations (TTVs) of Kepler - 19b, over 8 quarters of Kepler photometry, although neither mass nor period could be determined.

As suggested previously, however, the variation of stellar radiation over time and planetary orbital distance are as critical to the development of Earth - type planets as their mass.

I also think your statement about the steady state of the planet and it causing the planet to shine the same amount of energy all the time is vulnarable (think of the variations of distance between the sun and the earth over a year).

First of all, if one examines the complete geological record of global temperature variation on planet Earth (as best as we can reconstruct it) not just over the last 200 years but over the last 25 million years, over the last billion years — one learns that there is absolutely nothing remarkable about today's temperatures!

It is no surprise there is significant disagreement over the amount of warming estimated — as James Hansen and the Goddard Institute for Space Studies explain7, there is no clear definition of what we mean by absolute surface air temperature and wide variation in the estimated mean surface temperature of the planet.

We are not dealing with a beaker in a laboratory here — unless these modelers can explain all climate variation on the planet over the last several billion years.

We do not know with any precision what the actual mean temperature of the planet is at any given time and most of the figures given here are various guesstimations of the «anomaly» (variation from estimated mean for the time of year over some period of the very recent past, commonly 1951 - 1980 but not always).

In other words, the PDO or whatever could pull the surface temperatures out the of the range of variation from the trend line over the preceding 30 years without telling us anything interesting about the overall heat gain of the planet.

Some people wonder if the reason the sea ice is declining and the planet is warming can be explained by sunspots, which are related to variations in the Sun's energy output over time.

Since that variation in the climate sensitivity occurs daily over about a third of the planet, the part of the planet where the energy enters the system, it is not unreasonable to think that the global climate sensitivity should be a function of temperature.

However, we are waiting for a concrete (ie sensible) definition of what climate change means on planet that has seen a massive range of climatic variation over 4.6 billion years.
