This report summarizes the conclusions of the substantial body of literature on the implications of both existing climate variability and future climate change for U.S. water resources. We have identified nearly 1,000 relevant peer-reviewed studies, and that number grows larger every day. As a result, this report must be considered just a snapshot in time, a summary of what we think we know, do not know, and would like to know at the beginning of the 21st century. In the coming years, we hope and expect that our understanding of the impacts of climate changes for U.S. water resources will improve, as will our understanding of the ability of existing and new technologies, policies, economic tools, and institutions to help us mitigate and adapt to those impacts.

Climate change is more than a tech problem, so we need more than a tech solution
At the COP 21 climate convention in Paris at the end of 2015, leaders from 194 nations agreed to pursue actions that will cut greenhouse gas emissions enough to keep global warming within 1.5 °C (2.7 °F) above pre-industrial conditions. Meeting this goal will avoid continued and increasing harm to people and ecosystems around the world caused by a changing climate, and it is also a great opportunity to turn the world into a place that embodies our collective and pluralistic values for the future. Neverthele...
Climate change to worsen drought, diminish corn yields in Africa
Original story at MIT News Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is therefore extremely sensitive to drought, and since 2015 its production has fallen dramatically as a result of record-setting drought conditions...
Financing urban adaptation to climate change
Municipalities across Europe increasingly acknowledge the need to adapt to climate change and have begun to adopt various measures. Meeting the costs of adaptation measures for climate change is, however, a major challenge. Municipalities have found innovative ways to overcome that challenge and have started implementing measures. These solutions could be relevant for other cities, towns and smaller municipalities too, and examples are collected and presented in this publication as an inspiration. It offers...
Transformational adaptation – when climate change means business as usual is no longer possible
1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic and impressive, but a more interesting settlement lies beneath it. Under medieval Germa, the remains of large stone buildings...
Study: Climate change could overwhelm U.S. electrical grid
Climbing temperatures associated with global warming could wreak havoc on the U.S. electrical grid, according to a new study on the economic and social costs of climate change. Published last week in the scientific journal Proceedings by researchers at the University of California-Berkeley, Stanford, and University of Michigan, the study says the country will need to spend at least $180 billion on the electrical grid by the end of the century to cope with peak consumption caused by rising temperatures. Because...
