Prof. Bothun, In answering your question, methane is removed from the atmosphere by reacting with atmospheric trace species such as OH, O(1D), and Cl. The atmospheric lifetime of methane varies with time and location, depending on the abundance of the other reactants. ... Measurements have shown a declining atmospheric methane growth rate since early 1980s. The decline of the growth rate in the 30-90N semi-hemisphere was 2-3 times more rapid than in the other semi-hemisphere. ...

SPACE WEATHER . The response of our space environment to the constantly changing Sun is known as space weather. ... Some of the most dramatic space weather effects occur in association with eruptions of material from the solar atmosphere into interplanetary space. ... Space weather disturbances are generally caused by solar storms. ... the Sun. ... Every object in the solar system experiences the equivalent of Earth's space weather, although its detailed characteristics differ from place to place. ...

... Energy balance in a planetary atmosphere . The earth is heated by solar radiation; a fraction of the energy absorbed is re-radiated. The temperature within Earth's biosphere depends on the balance between energy absorbed and re-radiated. Certain gases (carbon dioxide, methane) are very efficient at trapping the re-radiated flux . ... More energy leads to higher temperatures - many possible . ... Consider Venus - atmosphere dominated by carbon dioxide . ...

... To determine a lower limit to the sensitivity of current observations to measurements of NS surface temperatures, we have used data from the Einstein Slew Survey (Elvis et al. 1990) to establish temperature limits for 275 pulsars which received nonzero exposure during the survey. ... Filled squares correspond to pulsars actually detected in the survey data; the smaller symbols correspond to upper limits to the count rates. ...

Springtime in the Solar System . In our case, we can use the tilt theory of the seasons to make a prediction: that any tilted planet will have seasons, and that the strength of these seasons will depend on the amount of the tilt. ... At summer solstice, the north pole points straight at the Sun; the north polar regions have tropical weather, but the Southern Hemisphere is in total darkness. ... With a little trigonometry, you can calculate the angle of the Sun and the intensity of solar heating. ...

... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...
