Far away from the accreting object, you'll have an accretion disk irrespective of the magnetic field. As material advects down the accretion disk, it looses angular momentum (though it is rotating faster and with the shorter period). So without a magnetic field, the specific angular momentum...

If I understand correctly, your question is why do the higher latitudes have a higher temperature increase? And why is the northern hemisphere warming larger? If so, then here's the answer. Irrespective of the source of warming (whether anthropogenic or not...), the climate variations at...

Often, most of the energy lost by the body is not in the form of "black body radiation", but instead through conduction to the air and heat going to evaporate our sweat (latent heat). Think about it, when it is above 37C outside, we should be heating from the environment, both through radiation...

yes, your physical intuition about the physical significance is correct. The exp(-E/kT) comes from the Boltzmann distribution, the exp(-b/sqrt(E)) comes from the penetration factor. The first function decreases with energy (there are less fast particles), the second increases (it is easier...
