Following the decision of the panel at its 43rd Session to accept the invitation from the UNFCCC, at its 44th Session, the Panel approved the outline of Global Warming of 1.5 °C, an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to More »

A new study reports a counter-intuitive finding that China and India, the two most populous and emerging countries, rather than the developed nations, are leaders in greening the lands through planting of trees and intensive crop cultivation   BOSTON – A team of researchers led by Boston University has just published a NASA-funded study titled “China and India lead in greening of the World through land-use management” in the journal Nature Sustainability More »

It is generally considered that the perennial glaciation of Greenland lasting several orbital cycles began around 2.7 Ma along with the intensification of Northern Hemisphere glaciation (NHG). Both data and model studies have demonstrated that a decline in atmospheric pCO2 was instrumental in establishing a perennial Greenland ice sheet (GrIS), yet models have enerally used simplistic pCO2 constraints rather than data-inferred pCO2 evolution. Here, using a method designed for the long-term More »
