Best Job Ever: Mapping “California’s Galápagos”

Cartographers and National Geographic grantees Marty Schnure and Ross Donihue traveled to the little-known Farallon National Wildlife Refuge to document the scientists who live there and to create an interactive digital map to allow the public to explore the islands from afar. The Farallon National Wildlife Refuge is closed to public access to protect this…

C40 launches new report showcasing obstacles and solutions to climate action in cities

For the first time, representatives from more than 80 of the world’s largest cities have revealed the barriers that are limiting their ambitions to tackle climate change, in a new analysis released today by C40 Cities Climate Leadership Group (C40). Unlocking Climate Action in Megacities also presents a corresponding set of innovative and replicable solutions to overcome…

Informal settlements and climate change: An opportunity and challenge for cities of emerging economies

By Mayor Mpho Parks Tau of Johannesburg The unprecedented growth of cities in emerging economies, coupled with the legacy of apartheid in South Africa has, since the early 1990s, led to a rapid increase in informal settlements, or slums, in Johannesburg. As the economic heartland of South Africa, it is estimated that Johannesburg receives more…

Study: Half a Degree Matters

Last week more than 150 nations signed the Paris Agreement, pledging to hold the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. Now, the first comprehensive analysis of the impacts of that half centigrade difference…

C40 Cities Awards 2016 now open for submissions

C40 Cities Climate Leadership Group (C40) today launched a global call for submissions to the C40 Cities Awards 2016. All cities demonstrating leadership in climate action are encouraged to apply for a chance to be recognised in the world’s foremost sustainability awards. The fourth-annual C40 Cities Awards are being held in partnership with Bloomberg Philanthropies.…

A Pacific salmon hub is under threat

The Skeena River snakes out of fir-lined fjords on the misty northern coast of British Columbia, and washes over a thousand-acre sandbar. Flora Bank is a biological bottleneck over which millions of finger-length young salmon enter the sea each spring. Scientist Allen Gottesfeld calls Flora Bank the “Grand Central Station” for the watershed. All streams…

Lake Suwa’s Shinto Legend and the Oldest Lake Ice Record on Earth: What It Tells Us About Climate Change and Variability

By Lisa Borre Shinto priests observing an ancient legend recorded ice freeze dates on Lake Suwa in Japan starting in the 15th Century. On the other side of the world, a local merchant began a tradition of recording ice thaw events on the Torne River in Finland in the 17th century. Both traditions continue to…

Our Ocean’s Future In An Era of Change

Imagine you live on the East Coast.  NOAA—the federal agency that tracks hurricanes—has spotted a tropical storm brewing in the mid-Atlantic. Over the next few days, the storm develops into a Category 5 monster.  NOAA’s best available forecasts show a possible landfall across over 600 miles of US coastline – and your town has a…

Wolf – Caribou Detente? Clues Hidden on Lake Superior Islands

Qalipu, it’s called by Canada’s Mi’kmaq people. To others, it’s the elusive gray ghost of the far northern forest. Most know it simply as caribou. Woodland caribou are medium-sized members of the deer family. In Canadian provinces such as Ontario, these shadows in the forest are listed as threatened – quickly vanishing. Non-migratory woodland caribou…

Nations to Sign Paris Climate Agreement Friday

Four months after it was finalized by delegates to the Paris Climate Change Conference, the Paris Agreement will be signed by more than 100 nations on Friday. While the agreement is facially insufficient to meet its overall emissions objectives, the signing of the Paris agreement nevertheless is significant. It brings into effect the approach and…

Uncharted Arctic waters: A new opportunity for exploitation, or conservation?

Co-authored by Erica Cirino When thick sheets of sea ice began melting in the Arctic waters around Svalbard, Norway, a few years ago, a new expanse of sparkling blue sea opened up. As climate change continues to drive ice melt here on the previously untouched waters of the North Barents Sea, what many ocean conservationists…

Climate-Change-Related Precipitation Extremes Hard to Predict

Scientists have warned that severe drought and precipitation are among the risks of greenhouse-gas-induced climate change, but a study published in the journal Nature finds that extremely warm temperatures do not always translate into record wet and dry extremes. Highlighting the complexities in predicting the effects of planetary warming on precipitation, lead author Fredrik Ljungqvist…

Antarctic Ice-Sheet Collapse Could Trigger Rapid Sea-Level Rise

A study published in Nature finds that Antarctic ice-sheet collapse driven by greenhouse gas emissions could double the sea-level rise predicted for this century—from 3.2 feet according to a three-year-old United Nations estimate to upward of 6.5 feet by 2100. The research builds on the work of other recent studies pointing to an irreversible melting…

Mayors, city networks and urban stakeholders worldwide call for an IPCC Special Report on Cities and Climate Change

Over 25 organisations have now joined forces to show their support for the Special Report proposal, to be decided during the IPCC 43rd Session in Nairobi on April 11-13  Cities are already facing the impacts of climate change and are highly vulnerable to a range of climate hazards, including sea level rise, street flooding, landslides, droughts, epidemics and…
