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.

The lack of interest in climate adaptation and mitigation among national-security policymakers reflects a profound misunderstanding of the risks that climate change poses to global stability. To avert catastrophe, the international community must help the world’s most vulnerable countries strengthen their resilience.

The Center for Climate and Security (CCS), a non-partisan institute of the Council on Strategic Risks, has a team and distinguished Advisory Board of security and military experts. CCS envisions a climate-resilient world which recognizes that climate change threats to security are already significant, unprecedented and potentially existential, and acts to address those threats in a manner that is commensurate to their scale, consequence and probability.

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.
