The document discusses global climate change and its causes and effects. It notes that physical evidence of climate change includes rising global temperatures in air, land and water; ice loss from glaciers and ice sheets; and changing plant and animal distributions. The main cause of climate change is rising CO2 and methane levels that increase the greenhouse effect. This leads to melting ice sheets, altered biomes, sea level rise and effects like loss of coastal habitat and species extinction. China is the largest carbon dioxide emitter, producing 7.2 tons per person, while the US produces 17.3 tons per person. Addressing climate change requires a multidisciplinary approach across many fields like biology, chemistry, engineering and more.

13. Physical evidences of global climate change :
•Record-breaking global average temperatures for
air, land surfaces, lakes, and oceans.
•Ice losses from mountain glaciers and from the
Greenland and Antarctic ice sheets.
•Declining soil-moisture conditions and resultant
effects on crop yields.
•Changing distributions of plants and animals.
•Global impact of global sea-level rise, which
threatens coastal populations and development.

Carbon Dioxide Emission
China took the lead in overall carbon dioxide
emissions (29%), with the United States second
(16%), and the European Union third (11%).
On a per capita basis in 2011, China, with
19.5% of global population, produced 7.2 tonnes
per person, on par with the European Union (at
7.5 tonnes per person). The United States, with
4.5% of world population, produced 17.3 tons of
CO2 emissions per person. Among the world’s
major industrialized countries, Australia had the
highest per capita CO2 output at 18.3 tonnes per
person in 2011.

16. Climate Change Science :
It is an interdisciplinary study of
the causes and consequences of
changing climate for all Earth
systems and the sustainability of
human societies.
Climate change is one of the most
critical issues facing humankind in the
twenty-first century

18.  There is still a considerable lack of awareness about the
interrelated nature of all human activities and the
environment.
 It is due to inaccurate and insufficient availability of
information, especially in developing countries.
 Sensor based in situ data collection, remotely sensed
data products, Geographical Information System based
analysis etc., would enhance the precision and quality
of environmental analysis.
 Besides, there is an urgent need to increase the public
sensitivity to environment issues and involvement of
various disciplines in solving environmental problems.
