Approximately 117 million more people could face water shortages if global temperatures increase 2 degrees Celsius above pre-industrial levels compared to a 1.5-degree Celsius increase in temperatures, a new study suggests. The world’s water cycle, including evaporation and precipitation, is expected to intensify with global warming, according to the study. This could affect the distribution of freshwater and constrain the global water supply, which poses risks to national food security, economic prosperity and societal well-being.

By Larry O’Hanlon Using hydraulic fracturing to extract oil and natural gas from shale is a common technique used worldwide. Because the technique requires large amounts of water, however, it raises the question of whether it could lead to water shortages or competition with other water uses, especially agriculture. In a new paper in the AGU journal Earth’s Future, Lorenzo Rosa and his colleagues evaluated the impacts of hydraulic fracturing …

Rising sea levels will accelerate this century and beyond, exposing hundreds of millions of people to flooding and other coastal hazards by the year 2300. But acting early to lower greenhouse gas emissions can slow that rise, say scientists in two new studies in Earth’s Future, an open access journal published by the American Geophysical Union.

While Earth’s average annual temperature has increased at a steady pace in recent decades, there has been an alarming jump in the severity of the hottest days of the year during that same period, with the most lethal effects in the world’s largest cities, a new study finds.

Researchers have developed new, high-resolution climate models that may help policymakers mitigate the effects of climate change at a local level.

Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

A well-designed climate observing system could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits by providing decision makers information they need to protect public health and the economy in the coming decades, according to a new study published today.

Humankind’s contribution to the amount of nitrogen available to plants on land is now five times higher than it was 60 years ago, mainly due to increases in the synthetic production of fertilizer and nitrogen-producing crops, according to a new study. This increase in nitrogen parallels the exponential growth of atmospheric carbon, the main culprit behind climate change, and could pose as much of a danger to Earth’s environment, according to the study’s authors.

How will future disasters affect countries in Eastern Europe and Central Asia? Researchers aiming to answer this question used projected changes in population and Gross Domestic Product (GDP) for 33 countries, along with climate, flood and earthquake risk models, to estimate how each country is affected by flooding and earthquakes now and in the future. In addition, the earthquake model was used to estimate fatalities and capital losses from a strong quake.
