(a) to keep the global average temperature increase well below 2 degrees Celsius above pre-industrial levels and to continue efforts to limit the increase in temperature to 1.5 degrees Celsius above pre-industrial levels, the potential to significantly reduce the risks and effects of climate change; In 1992, President George H.W. Bush joined 107 other heads of state at the Rio Earth Summit in Brazil to adopt a series of environmental agreements, including the UNFCCC framework, which is still in force today. The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term. The pact does not set limits on greenhouse gas emissions from individual countries and does not contain enforcement mechanisms, but establishes a framework for international negotiations on future agreements or protocols to set binding emissions targets. Participating countries meet annually at a Conference of the Parties (COP) to assess their progress and continue discussions on how best to combat climate change. The IPCC notes that climate change is limited only by a “substantial and sustainable reduction in greenhouse gas emissions.” While the benefits of presenting a single global temperature threshold as a dangerous climate change can be discussed, the general scientific view is that an increase in global temperatures of more than 2 degrees Celsius would be an unacceptable risk – potentially leading to mass extinctions, more severe droughts and hurricanes, and an arid region. While it is not clear that global warming will cause “sudden and irreversible changes” in Earth`s systems, the risk of exceeding the threshold only increases if temperatures rise. The 2015 Paris Climate Change Conference (COP 21) catalyzed an unprecedented vision of combating climate change and engagement by a wide range of non-state actors, including businesses and investors, sub-national governments and civil society organizations. Governments have taken a series of measures in … We are still being announced. More than 3,600 U.S. heads of state and government sign cities, states, tribes, businesses, colleges and universities to say they will continue to support climate change efforts to meet the commitments made in the Paris Agreement. The membership list continues to grow and inspire new coalitions emerging in other countries.
The United Nations has released a new emissions report that indicates that even if all current climate plans are implemented, temperatures are expected to rise by 3.2 degrees Celsius, which will have even greater and destructive climate effects. Collective ambitions must more than quintuple from current levels to achieve the reductions needed for the 1.5oC target over the next ten years.
