Yesterday, the Intergovernmental Panel on Climate Change (IPCC) released the highly anticipated second for this year report. The document, found to be the most comprehensive assessment done to date, warns that global warming is irreversible and humans will never be able to adapt to it completely. The major thread would come from exhaustion of food and fresh water resources due to increased risk of flooding.
Scientists from around the world gathered in Yokohama, Japan, to analyze and finalize the outcome of millions of scientific findings and evidence on the impacts of global warming. Despite the lengthy discussions, an agreement was reached, and the conclusion is one that nobody would like. According to the report, each part of the planet will be affected by climate change. This is already apparent on all continents, where natural systems have experienced and are still experiencing changes in order to adapt.
The impacts on natural systems will be devastating, and observed in a highly significant short-term. The first ecosystems at risk will be the coral reefs and the Arctic sea ice, due to severe ocean acidification. Animals on land and sea will begin to migrate towards colder areas and altitudes.
For humans, the impact will be severe. The major concern is ensuring food and fresh water resources. Not only that crop yields and fresh water resources will show incredible losses already in the coming few decades, but the increase in global population will further increase the pressure. In addition, people will be affected by more frequent extreme events, and they will need to migrate to more suitable regions creating issues of national security.
The report is based on more than 12,000 peer-reviews scientific publications. It shows evidence that climate change is really happening, and there is no room for doubt, denial or excuses for inaction. There is no single country to blame, and therefore all forces should be joint so that adequate and fast action is taken immediately. The scientists, who authored the report, clearly warn that if the evidence is not taken seriously, the consequences on human health, food security and development will be severe.
