The first time I met Ron Naveen was in the dining room of an Antarctic cruise vessel. Most passengers on the Akademik Ioffe were dressed for the south pole; two or three base layers, lots of high-quality goosedown. Naveen was wearing a very old pair of jeans, a baseball cap emblazoned with images of hairy penguins, a disintegrating T-shirt and a pair of sandals. I reckoned, with his afterthought hair and warm eyes, he must have been in his mid-70s. He looked, frankly, like a bum.

Over the next few days, I watched Naveen in penguin colonies throughout the Antarctic peninsula. All the time, he talked to camera about the different breeds and the survival issues that they faced. He talked about corners of the Antarctic continent where few people had ever been, the challenges posed by increased tourism and the temperamental life cycle of the penguins’ main food source, krill.

A series of initiatives and recent investment successes in the field of renewable energy were announced at the White House Clean Energy Investment Summit in June.

“Unbelievably exciting advances" are "happening in real time” in the field of clean energy, senior adviser to the president Brian Deese, told summit attendees. Mr. Deese spoke of progress made in meeting the “global challenge” in the field of renewable energy, and characterized the advances his team and the Obama administration have made as “improbably American success[es].” Chief among these gains, Deese noted, are a 50 percent decrease in the cost of solar energy and a three-fold increase in the amount of energy produced by wind since 2009.

NEW “holistic” plans to create an affordable green heating supply for Scotland will have financial and environmental benefits, according to green campaigners.

Scottish ministers say the country’s heat system should be largely decarbonised by 2050 in an effort to battle climate change.

Early in June, the United Nations climate change negotiations wrapped up in Bonn, Germany. The negotiations, aimed at consolidating a text in time for the massive COP21 conference in Paris later this year, succeeded in trimming the agreement draft a mere five pages in 10 days of talks -- down from 89 pages to 85.

The co-chairs of the process -- representatives from Algeria and the United States -- stressed the importance of investing time in Bonn building trust rather than streamlining the text. They lauded countries' willingness to cooperate, all the while dismissing that it would require months to reach a meaningful agreement at this pace, not the 10 days that are actually scheduled between now and Paris.

Environmental degradation has emerged as one of the key challenges facing Lebanon’s socio-economic development, costing the country $908.8 million each year.

What initiatives aimed at improving the overall efficiency and effectiveness of solid waste management is the Ministry of Environment currently undertaking?

Fourteen recommendations to improve the regional response to climate change have been agreed to following a meeting of the Middle East and North Africa region, held in Geneva, Switzerland on 28-29 2015, and hosted by Lebanon. The meeting, gathering eleven countries from the Middle East and North Africa region, was the last in a series of Climate Vulnerable Forum workshops being convened during 2014-2015 in Africa, Asia, the Caribbean and Latin America, the Middle East and the Pacific, and involving 50 countries.

The Climate Vulnerable Forum regional event for the Middle East and North Africa was organized by the Permanent Mission of Lebanon to the United Nations at Geneva and the Ministry of Environment with support from the United Nations Development Program (UNDP). 11 governments participated in the event, with 14 recommendations adopted by Egypt, Jordan, Lebanon, Morocco, Palestine, Sudan, Tunisia and Yemen.

Planning Commission Water Resources Chief Naseer Ahmed Gilani said that Pakistan is facing an annual loss of $24 billion due to the adverse impacts of climate change and environmental degradation.

He was addressing a seminar, early in June, titled combating climate change impacts arranged by the Capital Development Authority (CDA) in connection with the World Environment Day.

After years of opposing efforts to fight climate change, Europe’s biggest oil and gas corporations have made a stunning about-face.

In a letter addressed to the head of the United Nations Framework Convention on Climate Change, the chief executives of Shell, BP, and four other energy giants asked the world’s political leaders to put a price on carbon.

Continued warming of the Earth’s oceans over the next century could trigger disruptions to marine life on a scale not seen in the last 3 million years, scientists warn in a study released in June.

The changes could include extinctions of some of the ocean’s keystone species as well as a widespread influx of “invasive” animals and plants that migrate to new territory because of changing environmental conditions, the report says.

The Norwegian Parliament voted early in June to order the country’s huge oil fund — at $890 billion, the world’s largest sovereign wealth fund — to pull billions of dollars of investments out of companies that derive 30 percent or more of their business from mining or burning coal. The move is a major boost to the three-year-old campaign to persuade large investors to divest their fossil fuel stocks. And it could add to the momentum toward concrete action at the climate-change summit conference to be held in Paris in December.

That much is good. There is, however, a problem. Norway is also Europe’s biggest producer of other fossil fuels, and the money that the country is pulling out of coal came from more than four decades of pumping oil and gas out of the North Sea. Coal may be a worse offender on the climate change front, and the Norwegian legislators may truly have the planet’s best interests at heart, but it is hard to avoid the perception of hypocrisy in Norway’s selective combat against carbon emitters.
