Question

it was very hot yesterday in the uk the maxiuman temperature in london and some parts of the Uk was 25 degrees celsius have really seen the effects of gobal warming now i think we have already

Answer 1

It was hotter than this in April last year, this April was cold, by your theory that means things are actually getting colder.

2003 was a summer heatwave, almost 40 degrees in places, since then we've not had a single decent summer. So no I don't think seasonal variations in temperature are linked to global warming.

Answer 2

Warmer air than normal does not necessarily indicate global warming per se.   The warm or hot air,  as it were is a response to an existent airmass.   If you get warm southerly winds for a sustained period of time the temperature will be warmer than normal.   Conversely,  a linger cold front with strong northerly winds would signal a vigourous cold spell.

The relative warming is really a response to the fluid dynamics of the atmosphere.    Temperatures act to offset each by the various methods of heat transfer, such as advection,  mostly commonly noted in warm fronts.

Remember the atmosphere is self-regulating.  Note: Remember this again.  'For each action,  there is an equal and opposite reaction.
