The Intergovernmental Panel on Climate Change (IPCC) issued a report yesterday that says the effects of climate change are already occurring on all continents and across the oceans. The world, in many cases, is ill-prepared for risks from a changing climate. The report also concludes that there are opportunities to respond to such risks, though the risks will be difficult to manage with high levels of warming.
The report, titled Climate Change 2014: Impacts, Adaptation, and Vulnerability, from Working Group II of the IPCC, details the impacts of climate change to date, the future risks from a changing climate, and the opportunities for effective action to reduce risks. A total of 309 coordinating lead authors, lead authors, and review editors, drawn from 70 countries, were selected to produce the report. They enlisted the help of 436 contributing authors, and a total of 1,729 expert and government reviewers.
“Nobody on this planet is going to be untouched by the impacts of climate change,” said Rajendra Pachauri, chair of the IPCC.
In response to IPCC report Sonja Ruetzel, Director of Aid & International Development Forum (AIDF) commented: “In light of the IPCC report highlighting global warming, high risk of natural disasters, lack of fresh water resources and threat to global food supplies, AIDF continues to strongly support food and water security collaborations as well as disaster relief projects globally. Now more than ever I believe that we need to encourage governments, NGOs, private organizations and local communities to build partnerships and better understanding to prepare for the imminent climate change”.
The report concludes that responding to climate change involves making choices about risks in a changing world. The nature of the risks of climate change is increasingly clear, though climate change will also continue to produce surprises. The report identifies vulnerable people, industries, and ecosystems around the world. It finds that risk from a changing climate comes from vulnerability (lack of preparedness) and exposure (people or assets in harm’s way) overlapping with hazards (triggering climate events or trends). Each of these three components can be a target for smart actions to decrease risk.
Future risks from a changing climate depend strongly on the amount of future climate change. Increasing magnitudes of warming increase the likelihood of severe and pervasive impacts that may be surprising or irreversible. “With high levels of warming that result from continued growth in greenhouse gas emissions, risks will be challenging to manage, and even serious, sustained investments in adaptation will face limits,” said Field.
Observed impacts of climate change have already affected agriculture, human health, ecosystems on land and in the oceans, water supplies, and some people’s livelihoods. The striking feature of observed impacts is that they are occurring from the tropics to the poles, from small islands to large continents, and from the wealthiest countries to the poorest.
“The report concludes that people, societies, and ecosystems are vulnerable around the world, but with different vulnerability in different places. Climate change often interacts with other stresses to increase risk,” Field said.
Field added: “Understanding that climate change is a challenge in managing risk opens a wide range of opportunities for integrating adaptation with economic and social development and with initiatives to limit future warming. We definitely face challenges, but understanding those challenges and tackling them creatively can make climate-change adaptation an important way to help build a more vibrant world in the near-term and beyond.”
