क्यों और कैसे होता है

कारण और संदर्भ

Climate change is a long-term statistically significant change in climate means or variability, from natural and human causes. The governing relationship is: Greenhouse-gas emissions alter radiative forcing, warming the climate system and triggering feedbacks in ice, oceans, water and ecosystems.

यह कैसे काम करता है

Greenhouse-gas emissions alter radiative forcing, warming the climate system and triggering feedbacks in ice, oceans, water and ecosystems.

मुख्य तथ्य

• Carbon dioxide, methane and nitrous oxide are important anthropogenic greenhouse gases.
• Mitigation reduces causes; adaptation reduces harm from impacts.
• Climate differs from weather by the time scale and statistical pattern considered.

ज़रूरी शब्द
