This happened at the Jakobshavn Glacier front, 40km inland from Ilulissat Greenland. It is the most productive glacier in the northern hemisphere and everyday, 40 meters of ice breaks off. Once in a while, a huge piece breaks off and this is the largest one ever recorded on video!

An iceberg the size of Manhattan that broke off of Greenland’s massive Jakobshavn Glacier into the sea has been spotted by one of the European Space Agency’s Sentinel satellites. We discuss how climate change is contributing to the rapidly rising Arctic temperatures and further destabilizing the ice sheet covering Greenland on the Lip News with Mark Sovel and Elliot Hill.

The Arctic is warming faster than any other place on Earth. This affects weather and increases coastal erosion threatening many Alaskan communities. But with melting sea ice come new opportunities for shipping and development. Will the oil, gas and mineral rich Arctic lead to a rush for development? Might this lead to conflict and to serious consequences for the environment? Earth Focus looks at the changing face of the Arctic today.

In 2012 General Secretary of China Xi Jinping announced what would become the hallmark of his administration: The China Dream.
This episode of “Mosaic” begins with a TV news clips of Xi, describing the dream as the “national rejuvenation,” improvement of people’s livelihoods, prosperity, construction of a better society, and a strengthened military. He specifically addresses the young people, “dare to dream, work assiduously to fulfill the dreams and contribute to the revitalization of the nation.”
Further, he calls upon all levels of the Party and the government to facilitate favorable conditions for their career development. Xi told young people to “cherish the glorious youth, strive with pioneer spirit and contribute their wisdom and energy to the realization of the Chinese dream.” Our host shares with what the China Dream is in political terms, providing data and stats as to the economic and political goals of the China Dream plan.
But what does it mean, how does this dream play out in real life, at all levels of society, and particularly to China’s youth? And, why now? How is this dream connected to economic achievement in the country?
Through the selected collection of stories, we attempt to address these questions and ideas and provide a glimpse into a wide swathe of social strata, from the bottom of society to the very top.

Can religion save China’s environment? Filmmakers Gary Marcuse and Shi Lihong capture a surprising trend in China in their new film Searching for Sacred Mountain. China is beginning to draw on its religious heritage — including Buddhism, Daoism, Confucianism and other traditions to address the country’s growing environmental challenges. The film profiles the Tibetan monastery at Baiyu in the Nianbaoyuze mountain range, a sacred and nationally protected park – which epitomizes the intersections between religion and environment and China. An abridged version of the film with commentary by filmmaker Gary Marcuse. Produced in collaboration with the Pulitzer Center for Crisis Reporting, Face to Face Media and Wild China Film.

There are so many different dimensions to water – it provides habitat for many plants and animals, energy and recreation for millions of people, and is essential for life. Yet . . .
HALPERIN: “It seemed like it was only covered when there was a crisis, which due to climate change seems to be happening more and more. So we wanted to deepen people’s understanding of the resource on which our lives depend – to conserve it, to protect it, and most of all to respect it – not only for what it provides to us as humans, but for wildlife, and habitats, and ecosystems.”
That’s Frani Halperin, co-executive producer of H2O radio, a weekly program about water. She says that in discussing water sustainability, they inevitably cover climate change.
HALPERIN: “The story of climate change for us is told through water. So that means more extreme weather, severe droughts, floods, sea level rise, melting ice caps. It doesn’t seem that there’s a story out there that we can’t link back to climate change.”
Since water is a resource that affects everyone, Halperin hopes that by using water to talk about climate change, people will learn more and be inspired to get involved.

Wild bees in the US have declined in many farming areas according to the first national effort to map their numbers.
The study suggests that between 2008 and 2013, the numbers of wild bees went down across almost a quarter of the US.
The researchers say that the conversion of land to grow corn for biofuels is a key element in the decline.
If the trend continues say the scientists, it could drive up costs and destabilise crop production.
Wild bees play an important role in pollinating many US crops and plants. It’s estimated that they contribute around $3bn to the value of agriculture every year.
Wild bees are highly valuable pollinators. Along with managed honey bees, they provide a critical ecosystem service by ensuring stable pollination to agriculture and wild plant communities. Increasing concern about the welfare of both wild and managed pollinators, however, has prompted recent calls for national evaluation and action. Here, for the first time to our knowledge, we assess the status and trends of wild bees and their potential impacts on pollination services across the coterminous United States. We use a spatial habitat model, national land-cover data, and carefully quantified expert knowledge to estimate wild bee abundance and associated uncertainty. Between 2008 and 2013, modeled bee abundance declined across 23% of US land area. This decline was generally associated with conversion of natural habitats to row crops.
We identify 139 counties where low bee abundances correspond to large areas of pollinator-dependent crops. These areas of mismatch between supply (wild bee abundance) and demand (cultivated area) for pollination comprise 39% of the pollinator-dependent crop area in the United States. Further, we find that the crops most highly dependent on pollinators tend to experience more severe mismatches between declining supply and increasing demand.
These trends, should they continue, may increase costs for US farmers and may even destabilize crop production over time. National assessments such as this can help focus both scientific and political efforts to understand and sustain wild bees. As new information becomes available, repeated assessments can update findings, revise priorities, and track progress toward sustainable management of our nation’s pollinators.
