Climate change, sea-level rise calls for drastic action, IPCC warns

According to the Intergovernmental Panel on Climate Change (IPCC) 6th report released on Monday, the world is warming faster than expected, and without decisive action, global temperatures will be about 10% warmer than expected. It will rise 1.5°C in 10 years early.

Composed of the world’s leading experts on climate change, the IPCC says global greenhouse gas emissions need to be at least 40% lower by 2030 than in 2019 to meet the 1.5°C Paris target said.

Professor Detlef van Vuuren of Utrecht University, one of the authors of the report, said:

“Without a significant policy tightening, this would be the last IPCC report that could possibly reach 1.5 degrees. You have to make an effort.”

The report highlights that the impacts of climate change are becoming more pronounced. Extreme rainfall, droughts and heat waves have become more frequent in recent years. Sea levels have risen 20 cm since 1900 and will continue to rise at a rate that is highly dependent on greenhouse gas emissions.

In practice, this means extreme water levels on the Dutch coast, which now occur once every 100 years, but will be 10 to 50 times more frequent. Amy Slangen, a researcher at the Dutch Institute of Oceanography NIOZ, said: “It is still possible to deal with climate change and sea level rise, but without swift action we face a desperate challenge.

The report argues that countries that have committed to meeting the Paris goals have both ambition and lack of action. He warns that every 1.5°C plus 0.1°C of warming increases the risk of extreme weather events and ecosystem collapse.

In addition, more than 3 billion people live in areas considered particularly vulnerable to the effects of climate change, and half the world’s population now experiences year-round water scarcity. Extreme weather events are also forcing people in Africa, Asia, the Americas and the South Pacific to move more and more.

The Dutch government has set a target of reducing greenhouse gas emissions by 49% by 2030 compared to 1990 levels and by 95% by 2050.

About 26% of the Netherlands is below sea level and a further 29% is vulnerable to river flooding. , protected by an intricate system of locks. Climate change, sea-level rise calls for drastic action, IPCC warns
