Land Degradation Accelerates Global Climate Change

The UN body dealing with climate change has issued a warning saying global food security is at risk if we do not change the way we use the planet’s resources.

In a major report on land use and climate change, the Intergovernmental Panel on Climate Change (IPCC) says rising global temperatures are creating more extreme weather events, such as heatwaves and droughts, leading to land degradation and desertification.

At the same time it says poor land-use practices are contributing to global warming.

The destruction of natural habitats to make way for livestock and cultivation, is responsible for about a fifth of global greenhouse gas emissions, and is reducing the land’s capacity to store carbon.

The report’s authors are calling for a shift to sustainable land-use practices, and for action to drastically cut greenhouse gas emissions.

While they have stopped short of telling people to stop eating meat they say reducing consumption will take pressure off our planet’s limited natural resources.

New Study Finds Sea Level Rise Accelerating

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data.

If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100—enough to cause significant problems for coastal cities.

2018 Was 4th Warmest for Globe

NOAA/NASA’s annual global analysis reveals that 2018 was the 4th warmest for the planet. The report shows record warmth for much of Europe, the Mediterranean, the Middle East, New Zealand and nearby ocean, and parts of the Atlantic and western Pacific. There were 14 billion dollar disasters in the U.S. in 2018 which accounted for $91 billion in direct losses, the 4th largest on record.
