Published on June 18, 2015, by Democracy Now, this report covers Pope Francis's encyclical on the environment and climate change. In the encyclical (available to download here), Pope Francis called for urgent action to protect the planet, urging leaders to hear "the cry of the Earth and the cry of the poor." He emphasized a moral imperative for all to safeguard the environment, advocating for a shift from a "throwaway" consumer culture in rich countries and an end to attitudes that prioritize profit over the common good. A key theme is the disparity between rich and poor, with the Pope noting the vast difference between those in "desperate and degrading poverty" and those with excessive possessions.

The discussion features Naomi Klein, author of "This Changes Everything: Capitalism vs. the Climate," who was invited to speak at the Vatican's "People and Planet First: The Imperative to Change Course" conference. Also joining is Nathan Schneider, a columnist at America magazine, a national Catholic weekly published by the Jesuits.

Arctic sea ice has reached a record low wintertime maximum extent for the second consecutive year. Scientists from the National Snow and Ice Data Center and NASA reported this finding, noting the extent reached 5.607 million square miles on March 24. This represents the lowest maximum extent recorded in the satellite era.

The "Doomsday Clock" stands at three minutes to midnight, reflecting the climate crisis as a threat to humanity as serious as nuclear weapons. While world leaders have largely failed to act, some, like Monaca, Pennsylvania's Borough Manager Mario Leone, Jr., are modeling solutions. Through Mr. Leone's energy-saving strategies, Monaca has reduced utility costs by 25 percent.

We spoke with guest editors Stephan Lewandowsky, Chair in Cognitive Psychology at the University of Bristol, and Richard Pancost, Professor of Biochemistry. They discussed their contributions to *Philosophical Transactions*.

Their work explores the complex relationship between scientific uncertainty regarding climate change and knowledge drawn from physical, economic, and social perspectives. This interdisciplinary examination offers valuable insights into a critical global issue.

Shell is preparing another attempt to extract an estimated 400 billion barrels of oil and gas from the Arctic. However, drilling in this region is expensive and dangerous.

Shell is preparing another attempt to extract an estimated 400 billion barrels of oil and gas from the Arctic. However, drilling in this region is expensive and dangerous.

Falling oil prices and potential government action could jeopardize Shell's ambitions in the face of these significant challenges.

Governments from over 190 nations will convene at the UN 2015 Paris Climate Conference (November 30 – December 11) to forge a new global agreement on climate change.

This year's summit holds greater promise than the unsuccessful 2009 Copenhagen meeting. Optimism stems from the growth of renewable energy and evolving stances among major polluters, including the US.
