December 2014 turned out to be a horrific end to the year for Sundarbans, the largest contiguous tidal mangrove forest in the world. On the morning of December 9, a tanker carrying furnace oil and a cargo vessel collided in Sundarban’s Shela river, the former sinking and spilling over 3.5 lakh litres of oil into a region popular for its rich biodiversity, including the endangered Irrawaddy dolphin, the Ganges river dolphin and the royal Bengal tiger. Within days, the impact of the toxic oil spill was visible – oil-coated marine creatures (dead or barley surviving) and sharp drop in the diversity of phytoplanktons and zooplanktons, among other signs. Thus, however, would not be the last disaster this region would witness – a ship with fertilizer and two vessels with coal would all sink in the next few years because of shipping bans being withdrawn as quickly as they are imposed.

In November 2014, the U.S. and China (President Barack Obama and President Xi Jinping) unveiled a deal to reduce their greenhouse gas output, with China agreeing to cap emissions for the first time and the U.S. committing to deep reductions by 2025. China, the biggest emitter of greenhouse gases in the world, agreed to cap its output by 2030 or earlier, if possible. The agreement was seen as being a significant boost to international efforts to reach a global deal on reducing emissions beyond 2020, at a U.N. meeting in Paris the following year.

Administration officials acknowledged that Mr. Obama could face opposition to his plans from a Republican-controlled Congress. While the agreement with China needs no congressional ratification, lawmakers could try to roll back Mr. Obama’s initiatives, undermining the United States’ ability to meet the new reduction targets.

In the last two to three decades, hill-State Uttarakhand in the Himalayan region has seen several natural disasters. However, in June 2013, the disaster-prone area witnessed one of its worst natural disasters in the form of torrential rains and resultant flashfloods, claiming the lives of thousands of people and animals while not-so-quietly altering its landscape. The flashfloods also wiped out settlements and decimated livelihoods. The National Institute of Disaster Management, in one of its first reports in 2015 blamed “climatic conditions combined with haphazard human intervention” for the disaster. Environmentalists point out that adequate steps haven’t been taken to prevent or handle such disasters, including the recurrent Brahmaputra floods that have decimated several regions, especially Assam, over many years now.

REDD+, elaborately known as “Reducing emissions from deforestation and forest degradation and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks” in developing countries, is a programme under the United Nations Framework Convention on Climate Change. Though the talks began in 2005, the key aspects of this programme were finished by 2013. It is an important part of global steps to control climate change, and seeks to encourage developing countries to contribute to climate change mitigation efforts by “reducing greenhouse gas emissions (GHG) by showing, halting and reversing forest loss and degradation; and increasing removal of GHSs from the earth’s atmosphere through the conservation management and expansion of forests”.

It creates a financial value for the carbon stored in forests by offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. Developing countries would receive results-based payments for results-based actions. REDD+ goes beyond simply deforestation and forest degradation and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks.

An Arctic record was broken on August 26, 2012 and it was not good news. According to the U.S.-based National Snow and Ice Data Centre, the Japanese Aerospace Exploration Agency, and Norwegian, Danish and other government monitoring organisation that was the day the Arctic sea ice hit its lowest extent ever recorded since the beginning of the satellite record in 1979 – satellites showed it had shrunk to 4.1 million sq.km. The record it broke was 4.3 million sq.km. set in 2007. The heat and the subsequent melting have continued over the years, and 2019 was in line for the second lowest Arctic sea ice extent record.

If the Arctic begins to experience entirely ice-free summers, scientists say, the planet will warm even more, as the dark ocean water absorbs large amounts of solar heating that used to be deflected by the cover of ice. The new findings were published as climate negotiators in Poland are trying to reach a global consensus on how to address climate change.

On June 13, 2012 Australia’s then Environment Minister Tony Burke announced that the country would establish the world’s largest network of marine reserves. About one-third of the island-nation’s waters, running to over three million sq.km of reef and marine life around the country’s border will be covered, he said. While creating 60 reserves and also protecting the Coral Sea, the plan will also restrict fishing and oil and gas exploration, in a major step towards safeguarding the environment.

Highly protected areas such as the Coral Sea off Australia’s north-eastern coast and the adjoining World Heritage-listed Great Barrier Reef will also be protected from oil and gas exploration. Both areas, which cover a total 1.3m sq km, have shallow reefs that support tropical ecosystems with sharks, coral, sponges and many fish species.

The numbers of marine reserves off the Australian coast will be increased from 27 to 60.
