Rise in greenhouse gas concentrations jeopardizes Paris Agreement temperature targets

Geneva, 25 October 2021 (WMO) - The abundance of heat-trapping greenhouse gases in the atmosphere once again reached a new record last year, with the annual rate of increase above the 2011-2020 average. That trend has continued in 2021, according to the World Meteorological Organization (WMO) Greenhouse Gas Bulletin.

Deforestation Increased 12% Between 2019 and 2020, Threatening Climate Progress

New data analysis from WRI shows that deforestation increased by 12% between 2019 and 2020, destroying a Netherlands-sized area of primary tropical forests. In addition to the troubling implications of this forest loss for biodiversity and communities that depend on forests for drinking water, food and livelihoods, new research also suggests that current rates of deforestation are causing global forests to transform from carbon sinks to carbon sources, which will make it more difficult for countries trying to achieve emissions-reductions. Countries can learn much from indigenous communities about sustainable land and forest management. At least 36% of the world’s intact forests are on indigenous lands, and the deforestation rate on these lands is often lower than in other forest areas.

Food system impacts on biodiversity loss

Our food system has been shaped over past decades by the ‘cheaper food’ paradigm. Policies and economic structures have aimed to produce ever more food at ever lower cost. Intensified agricultural production degrades soils and ecosystems, driving down the productive capacity of land and necessitating even more intensive food production to keep pace with demand. Growing global consumption of cheaper calories and resource-intensive foods aggravates these pressures.
As a major contributor to global greenhouse gas emissions, our food system is also driving climate change, which further degrades habitats and causes species to disperse to new locations. In turn, this brings new species into contact and competition with each other, and creates new opportunities for the emergence of infectious disease.

For a City Staring Down the Barrel of a Climate-Driven Flood, A New Study Could be the Smoking Gun

Not all of the water from the planet’s melting glaciers is pouring into rivers and oceans. A surprising amount is building up behind unstable piles of rubble left behind by the retreating ice. As the Earth continues to warm, the swelling lakes threaten to burst through the glacial moraines holding them back and wash away the forests, towns and farms below.

Earth Is Losing Ice Faster Today Than in the Mid-1990s, Study Suggests

Earth’s ice is melting faster today than in the mid-1990s, new research suggests, as climate change nudges global temperatures ever higher. Altogether, an estimated 28 trillion metric tons of ice have melted away from the world’s sea ice, ice sheets and glaciers since the mid-1990s. And the annual melt rate is now about 57 percent faster than it was three decades ago.
