The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?
Climate change should be at the heart of national security plans, say experts.

Christopher Lockyear, secretary general of Doctors Without Borders/Médecins Sans Frontières (MSF), called today on the United Nations Security Council (UNSC) to demand an immediate and sustained ceasefire in Gaza. Addressing the Council at its monthly meeting on Gaza, Lockyear also called for the unequivocal protection of medical facilities, staff, and patients. “Meeting after meeting, resolution after resolution, this body has failed to effectively address this conflict,” Lockyear said. “We have watched members of this Council deliberate and delay while civilians die. This death, destruction, and forced displacement are the result of military and political choices that blatantly disregard civilian lives. These choices could have been—and still can be—made very differently.” After more than four months of war, nearly 30,000 Palestinians have been killed in Gaza amid Israel’s constant bombing and attacks. Approximately 1.7 million people—nearly 75 percent of the population—are estimated to be forcibly displace

Freshwater availability is changing worldwide. Here we quantify 34 trends in terrestrial water storage observed by the Gravity Recovery and Climate Experiment (GRACE) satellites during 2002–2016 and categorize their drivers as natural interannual variability, unsustainable groundwater consumption, climate change or combinations thereof. Several of these trends had been lacking thorough investigation and attribution, including massive changes in northwestern China and the Okavango Delta. Others are consistent with climate model predictions. This observation-based assessment of how the world’s water landscape is responding to human impacts and climate variations provides a blueprint for evaluating and predicting emerging threats to water and food security. Analysis of 2002–2016 GRACE satellite observations of terrestrial water storage reveals substantial changes in freshwater resources globally, which are driven by natural and anthropogenic climate variability and human activities.
