Beach building is keeping the Atlantic Coast from going under

The artificial build-up of beaches is buffering the U.S. Atlantic coastline against the effects of sea level rise, but that benefit may not last as sand gets harder to come by in the coming decades.

Study: Climate change could force outdoor workers to wake up far earlier

A new study published in Earth’s Future, a journal of the American Geophysical Union, indicates that if society tries to avoid the economic impacts of climate change on outdoor labor by shifting working hours, outdoor workers in many regions will need to start working well before dawn at the end of this century to avoid the effect of excessive heat stress.

Pacific Ocean typhoons could be intensifying more than previously projected

Changes to the uppermost layer of Earth’s oceans due to rising temperatures are likely causing an increase in intense Pacific Ocean typhoons, suggesting strong typhoons may occur more frequently than scientists project in the coming decades, according to new research.

Half-degree of warming could have big impact on water availability

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.

New study examines impacts of fracking on water supplies worldwide

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 …

Early climate action has big effect on rising sea levels

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.

Rise in severity of hottest days outpaces global average temperature increase

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.

Rising sea levels could weaken coral reefs’ protective influence on Brazil’s coast

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.
