- El-Nino
responsible for the increasing temperature of Indian Ocean – Study by
IITM, Pune
1.2
deg C rise in temperature during the past century; Note: Indian Institute of Tropical Meteorology; El-Nino controls
interplay between temperatures; Western Indian ocean which is cool usually than
central & eastern Indian ocean started showing stronger summer warming; this
is cause of El-Nino Events; These El-Nino events weaken the summer westerlies
over the Indian ocean (These winds are known to have cooling effect on the sea
surface by promoting evaporation); Usual
& large scale circulation may effect – monsoon, marine food webs,
fisheries; El-Nino repeats after the gap of 3-7 years and last usually about 12
months;

- IPCC - 5th
Assessment Report on Climate Change (IN FOCUS)
The
effects of the Climate Changes are visible across the globe;
Unexpected
floods, Drought become common phenomenon; Climate change has defined as a
identifical change in the climate of a region that exist long period of time;
Anthropogenic
activities – excess use of fossil fuels, exploitation of forests – Green-house
gas (CO2, NOx) emission a major cause of climate change; Study shows
considerable rise in global temperature; (Global Temperature up by 0.6 deg C
since 1900 and increase in CO2 level in Atmosphere)
Fallout
of climate change more evident – causes change in weather pattern – untimely
rains, heavy down pour, heat waves, prolonged & harsh summer;
Pose Risk / Ill effects: threat to global food security, Flood &
droughts, affecting infra including agriculture, reduce water supply,
increasing wild fire, disease outbreak, flood and erosion in the coastal areas,
melting of glaciers;
IPCC
– Intergovernmental panel on Climate Change – world body to assess the science
related to climate change – 1988 setup
by WMO & UNEP – endorsed by UNGA;
Provides
report – regular assessment of Climate change - helps nations & policy
maker;
Working
groups in IPCC Exe Comm.:
·
WG I: Physical
science Basis;
·
WG II: Climate
Change Impacts, Adaptation & Vulnerability;
·
WG III:
Mitigation of Climate Change;
·
Task force on
National GHG inventories;
1990
– first report; now 2014 – 5th Report (AR5) – predictions on global
climate;
Carbon
emission from burning coal; AR5 specially focus on the implication of the
climate change on Indian & countries in South Asia;
Serious
concerns: Flood, Cloud burst, Increasing ocean temperature, Health issue –
Social economic;
Human
Activity is the major cause of warming & climate change since mid-20th
century;
Economically
affordable if Phase out fossil fuel by the end of this century;
