Description Observations in fisheries sciences related to climate change foresee a future
with intensified climate change as a consequence of increased greenhouse gases
(GHGs) in the atmosphere because of human activities. The increase in GHGs
has resulted in warming of climate systems or global warming. In last 100 years,
ending in 2005, the average global air temperature near the earth’s surface has
been estimated to increase at the rate of 0.74 ± 0.18°C (1.33 ± 0.32°F) (IPCC,
2007). In the latest IPCC report (IPCC, 2014), climate model projections
indicated that the global surface temperature during the 21st century is likely to
rise a further 0.3 to 1.7°C (0.5 to 3.1°F) for their lowest emissions scenario and
2.6 to 4.8°C (4.7 to 8.6°F) for the highest emissions scenario. In the past, 15 of
the 16 warmest years have occurred since 2001 and rank among the 15 warmest
years in the instrumental record of global surface temperature since 1850.
Climate change and associated warming is increasingly being felt in many parts
of the globe including India. Climate change is predicted to lead to adverse,
irreversible impacts on the earth and the ecosystem as a whole. Although it is
difficult to connect specific weather events to climate change, increases in
global temperature has been predicted to cause broader changes, including
glacial retreat, arctic shrinkage and worldwide sea level rise (Mohanty et al.,
2010).The Chaliyar river is one of the west flowing rivers of Western Ghats. It has many tributaries such as Karimpuzha. Punnappuzha, Kuruvanpuzha, Tiruanchipuzha, Cherupuzha. etc. with a catchment area of 1535 sq. km. The total discharge of the river is 7775 Mm3, The river which was in a pristine condition before 4 to 5 decades has become highly degraded in the lower stretches by the effluents of Gwalior Rayons and in the upper stretches by various anthropogenic factors like deforestation, high siltation, dynamite fishing and use of copper sulphate for fishing. During the summer months, the water in the river is very low due to high run off during the wet months.
