Climate change impact on coastal fisheries and aquaculture in the SAARC
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 las...

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).
