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.
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

History
• 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.
