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.

Agroforestry Mitigates Climate Change
Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the global carbon, water, and nutrient cycles. Farming, as a direct driver for 80% of global deforestation, also releases...
Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture
Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years.This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable in the years to come. It is still unclear how and to what extent climate change will affect agricultural conditions. Some regions might...
Paleoclimatology: Examples of Ecological Impacts from Prehistoric Climate Change
Introduction Climate change is a pressing issue that has received a lot of attention from the media, our political leaders, and research institutions. Much research is produced on the environmental, ecological, and societal impacts of global warming. Discussions about climate change often focus on mitigation and adaptation to future climate scenarios. The purpose of this article is to shed light on past climates, which are useful for predicting the future environmental impacts of climate change. Paleoclimatology...
The Climate is Changing. Food and Agriculture Must Change Too.
On October 16th, we celebrate World Food Day. It is a day of action against hunger, which is one of the biggest global challenges. Since we expect that global population will reach 9.6 billion by 2050, we need to act now. Our global goal is to achieve Zero Hunger by 2030. This is because, food is the basic human need and without addressing climate change, we cannot produce sufficient quantities to reach that goal. Since climate change is a fundamental threat to global food security, this year’s theme of...
Paris Climate Change Agreement: What next?
The Paris Climate Change Agreement took a huge leap forward on 3 September when the world`s two biggest economies and emitters of greenhouse gases – the USA and China – announced that they would formally ratify the accord. This brings hope that the deal will be concluded this year. It also piles pressure on the UK to swiftly formalise its commitment to a contract it shaped and take its place among the 55 countries (representing 55% of global emissions) required to bring the Paris agreement into...
