International Responses to Climate Change

International Responses to Climate Change

Key Climate Change Organizations

  • United Nations Framework Convention on Climate Change (UNFCCC)
    • Established in 1992 at Rio Earth Summit.
    • Oversees international climate agreements (e.g., Kyoto Protocol, Paris Agreement).
  • Intergovernmental Panel on Climate Change (IPCC)
    • Scientific body under the UN providing assessments on climate change.
  • World Resources Institute (WRI)
    • Focuses on sustainability and climate change.
  • Greenpeace and Climate Reality Project
    • NGOs advocating for climate action.
  • Environmental Protection Agency (EPA)
    • U.S. government agency implementing climate policies.
  • Local & Regional Organizations
    • e.g., C40 Cities network.

Key Climate Change Programs & Initiatives

  • Paris Agreement (2015)
    • Global commitment to limit temperature rise below 2°C.
  • Kyoto Protocol (1997)
    • Binding targets for developed countries' emissions.
  • Net Zero Commitments
    • Many countries aim for net-zero emissions by 2050.
  • Carbon Pricing & Emission Trading Systems (ETS)
    • Policies to put a price on emissions.
  • Renewable Energy Programs
    • Investments in renewable energy sources.
  • Climate Finance Initiatives
    • Financial support for developing countries in climate efforts.

Key Milestones in IPCC History

  1. First Assessment Report (FAR) (1990)
    • Confirmed human-induced climate change.
  2. Second Assessment Report (SAR) (1995)
    • Strengthened evidence of human impact on climate.
  3. Third Assessment Report (TAR) (2001)
    • Introduced concepts of vulnerability and adaptation.
  4. Fourth Assessment Report (AR4) (2007)
    • Declared warming is unequivocal and human-caused.
  5. Fifth Assessment Report (AR5) (2013-2014)
    • Emphasized the need to limit warming to below 2°C.
  6. Sixth Assessment Report (AR6) (2021-2023)
    • Highlighted rapid and intensifying climate change impacts.

Key Agreements under UNFCCC

  • Kyoto Protocol
    • Set emission targets and mechanisms (e.g., Clean Development Mechanism).
  • Paris Agreement
    • Aims for global cooperation to limit warming; requires countries to submit climate action plans.

Carbon Credits and Mechanisms

  • Carbon Credits: Measure of reduced emissions or removals, traded in markets.
    • CERs: Issued under the Clean Development Mechanism.
    • Voluntary Carbon Credits: Used in voluntary markets.
  • Mechanisms of Kyoto Protocol:
    • Emission Trading, Clean Development Mechanism, Joint Implementation.

Importance of Global Cooperation

  • Collective efforts are crucial for effective climate action.
  • Developed countries are primarily responsible and must support developing nations.
