Warming homogenizes apparent temperature sensitivity of ecosystem respiration – Science Advances

INTRODUCTION Terrestrial ecosystem respiration (Re), the sum of autotrophic respiration from primary producers and heterotrophic respiration from consumers and detritivores, represents a fundamental biospheric function and plays a major role in the global carbon cycle and growth rate of atmospheric…

Ocean eddies strongly affect global mean sea-level projections – Science Advances

INTRODUCTION Satellite-observed sea-level measurements indicate an ongoing increase in the global mean sea level since the satellite era (1–3). Global mean sea-level rise (GMSLR) threatens low-lying coastal regions, and these regions will benefit strongly from sea-level projections to adapt their…

Global Warming Could Lead to Collapse of More than One-Third of Antarctic Ice Shelf – AZoCleantech

Written by AZoCleantechApr 9 2021 A new study shows that over one-third of the Antarctic’s ice shelf area could be at risk of crumbling into the sea if global temperatures increase to 4°C above pre-industrial levels. Image Credit: AndreAnita/shutterstock.com The comprehensive study…

Biden’s new 2030 climate change target: Will it be fair to other countries? – Vox.com

On April 22, President Biden will convene global leaders for a virtual climate summit in a bid to reassert US leadership and motivate countries to cut emissions much more aggressively. Of course, the US is only just recommitting to climate…

Lemurs and giant tortoises among species at risk if global warming reaches 3°C – EURACTIV

Unique island species including lemurs and the Galapagos giant tortoise could be at high risk of extinction if the planet warms by more than 3°C above pre-industrial levels, new research warns. EURACTIV’s media partner, The Guardian, reports. Analysis of 270…

Third of Antarctic ice shelf area at collapse risk due to global warming: Study – The Hindu

They noted that when melted ice accumulates on the surface of ice shelves, it can make them fracture and collapse spectacularly. Over a third of the Antarctic’s ice shelf area may be at risk of collapsing into the sea if…

Abrupt ice age climate changes behaved like cascading dominoes

(University of Copenhagen – Faculty of Science) Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of the climate system followed like a series of dominos toppling in succession. Today, sea-ice extent is being rapidly reduced, and it is uncertain whether this part of the climate system can trigger sudden future climate change.

X-ray study recasts role of battery material from cathode to catalyst

(DOE/Lawrence Berkeley National Laboratory) An international team working at Berkeley Lab used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices.
