Last month the U.S. Geological Survey estimated that without concerted intervention, as much as 67 percent of Southern California’s beaches could be lost to rising seas by the end of the century ... More than 42,000 homes in California will be under water—not merely flooded, but with seawater over roofs.

six other islands had large swaths of land washed into the sea and on two of those, entire villages were destroyed and people forced to relocate, the researchers found ... The study is the first that scientifically “confirms the numerous anecdotal accounts from across the Pacific of the dramatic impacts of climate change on coastlines and people,” the researchers wrote in a separate commentary on an academic website.

New data released by Yale researchers gives the most detailed view yet of public opinion on global warming. In Florida, the effects of climate change, including sunny-day flooding, are being felt across the state. Four southeast Florida counties — Miami-Dade, Broward, and Monroe and Palm Beach — stand out because of their concerted effort to work on climate issues together and to discuss it in nonpartisan terms.

The rising ocean, fed by melting glaciers and the expansion of warming water, is piling up water along America’s entire eastern seaboard. To compound the problem much of the mid-Atlantic coast is sinking, a hangover from the last ice age, meaning life and property is being swamped like never before... And yet with no overarching national sea level rise plan and patchy commitment from states, many coastal communities are left to deal with the encroaching seas themselves.

Last year saw the second highest number of billion-dollar disasters since 1980: 15 events that caused 138 fatalities and $46 billion in losses. But what’s particularly troubling is the number of two particular types of disasters: 2016 saw four inland flood events and eight severe storm events, more than any year on record. Both types of events have greatly increased in frequency over the last decade.

For years, China’s deserts spread at an annual rate of more than 1,300 square miles ... Nearly 20 percent of China is desert, and drought across the northern region is getting worse. One recent estimate said China had 21,000 square miles more desert than what existed in 1975 — about the size of Croatia. As the Tengger expands, it is merging with two other deserts to form a vast sea of sand that could become uninhabitable ... Climate change and human activities have accelerated desertification

adapting to coastal erosion by rebuilding infrastructure farther inland and resettling endangered communities is expected to cost between 5 and 10 percent of GDP in affected countries, according to the United Nations. It’s an open question how one of the poorest regions in the world should come up with the resources for costly sea walls and beach replenishment schemes.

in the future, in many countries, the coldest growing seasons are going to be hotter than anything those crops have seen in the past ... [in South Africa] By 2030, if the maize or corn varieties...are still in the field...we'll have a 30 percent decrease in production of maize because of the climate change... 30 percent decrease of production in the context of increasing population, that's a food crisis ... We have to get climate-ready crops in the field, and we have to do that rather quickly.

To behave as if the New York coastline is an immutable fact is to disregard not just science but history ... humans have thoroughly remade the city’s topography, leveling hills, channeling streams, draining ponds, creating new landfill out of construction debris. When workers were excavating the foundation of the redeveloped World Trade Center, they discovered...the hull of an 18th-century shipwreck — an eerie reminder that even our tallest towers sit on land claimed from the water.

Mountains support roughly a quarter of the globe's terrestrial biodiversity, contain about a third of its protected areas and house nearly half of the world's biodiversity hotspots. One reason for this biodiversity is that complex topography within mountains creates diverse climates within close proximity to one another ... Dobrowski and Parks suggest that areas within mountains are more climatically isolated and thus more vulnerable to climate change than previously reported.
