Global warming affecting Kerala weather - Palakkad

[Palakkadtourism.org]

Global warming refers to the increases in the average temperature of
the Earth's atmosphere and oceans in recent decades.

The term 'global warming' is a specific case of the more general term
'climate change' (which can also refer to cooling, such as occurs
during Ice ages). In principle, 'global warming' is neutral as to the
causes, but in common usage, 'global warming' generally implies a human
influence. However, the UNFCCC uses 'climate change' for human-caused
change, and 'climate variability' for other changes. Some organizations
use the term 'anthropogenic climate change' for human-induced changes.

An increase in global temperatures can in turn cause other changes,
including a rising sea level and changes in the amount and pattern of
precipitation. These changes may increase the frequency and intensity
of extreme weather events, such as floods, droughts, heat waves,
hurricanes, and tornados. Other consequences include higher or lower
agricultural yields, glacier retreat, reduced summer streamflows,
species extinctions and increases in the ranges of disease vectors.
Although warming is expected to affect the number and magnitude of
these events, it is difficult to connect particular events to global
warming. Although most studies focus on the period up to 2100, warming
(and sea level rise due to thermal expansion) is expected to continue
past then, since CO2 has a long average atmospheric lifetime.
