Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with recent advances in understanding of the climate system, some potential abrupt changes once thought to be imminent threats are now considered unlikely to occur this century. This report summarizes the current state of knowledge on potential abrupt changes to the ocean, atmosphere, ecosystems, and high latitude areas, and identifies key research and monitoring needs. The report calls for action to develop an abrupt change early warning system to help anticipate future abrupt changes and reduce their impacts.
The Climate is Changing. Food and Agriculture Must Change Too.
On October 16th, we celebrate World Food Day. It is a day of action against hunger, which is one of the biggest global challenges. Since we expect that global population will reach 9.6 billion by 2050, we need to act now. Our global goal is to achieve Zero Hunger by 2030. This is because, food is the basic human need and without addressing climate change, we cannot produce sufficient quantities to reach that goal. Since climate change is a fundamental threat to global food security, this year’s theme of...
Paris Climate Change Agreement: What next?
The Paris Climate Change Agreement took a huge leap forward on 3 September when the world`s two biggest economies and emitters of greenhouse gases – the USA and China – announced that they would formally ratify the accord. This brings hope that the deal will be concluded this year. It also piles pressure on the UK to swiftly formalise its commitment to a contract it shaped and take its place among the 55 countries (representing 55% of global emissions) required to bring the Paris agreement into...
How Climate Change will affect your Work Conditions
After the major discussions regarding Climate Change this month in Paris, 5 key points of the Paris Agreement on climate change are being presented: Limiting global temperature rise to “well below” 2 C Creation of the first universal climate agreement Providing help to poorer nations Each country publishing their greenhouse gas reduction targets, and maintaining these Reaching carbon neutrality by 2050 (meaning the amount of carbon produced can reasonably be absorbed by the earth and the...
The surprising link between the tapirs of Costa Rica and climate change
New studies suggest that protecting tapirs and other large seed-eating mammals is key to preserving carbon storage in rain forests. Esteban Brenes-Mora has been obsessed with tapirs — large, pig-like jungle dwellers — for as long as he can remember. It started with a sticker book his grandfather gave him as a child, and continued through zoo visits and into his university studies. “I’ve always been passionate about tapirs,” he says. “When I studied biology I was aiming for...
Water Loss management will be critical to climate change adaptation
Water loss management is one of the most important issues facing water suppliers around the world. The Sustainable Development Goals have made poverty alleviation and access to safe drinking water a political priority. Targets on providing safe drinking water as a basic human right aim to ensure everyone can access a safe water supply. Unfortunately, the reality is that many of the most vulnerable around the globe still struggle to find a reliable supply of safe drinking water. Water shortages are being experience...
