The Man Who Coined the Term ‘Global Warming’ on the Worst-Case Scenario for Planet Earth

By David Wallace-Wells



This week, to accompany our cover story on worst-case climate scenarios, we’re publishing a series of extended interviews with climatologists on the subject — most of them from the “godfather generation” of scientists who first raised the alarm about global warming several decades ago.

The oceanographer Wallace Smith Broecker is the man who coined the term “global warming,” way back in 1975, in a paper called “Climate Change: Are We on the Brink of a Pronounced Global Warming?” Broecker had already distinguished himself in his work on what’s called the “ocean conveyor belt” — the system of jet streams and other circulatory patterns that stir the planet’s waters, regulating heat along the way. Today, he is 84, still working at Columbia’s Lamont-Doherty Earth Observatory, and has given up hope that emissions reduction alone could avert dramatic climate change

UNESCO's report ahead of World Water Day on 22 March should serve as a wake-up call for every Indian. It highlights how India is staring at a deepening water crisis with few steps being taken to ameliorate this bleak situation. It predicts an intensified water crisis across the nation by 2050, with many parts of central India battling a withdrawal of 40 percent of the renewable surface water resources.

More than half of our rivers are heavily polluted. Contamination is no longer a problem with surface water alone but also with groundwater resources which have been found to contain both metallic contamination and also contamination from improper disposal of human excreta.

The Central Pollution Control Board has doubled the number of 'polluted' rivers from 121 to 275 in the last five years, blaming the huge quantities of untreated sewage being dumped into our rivers for this state of affairs.

The CPCB collated monthly water quality analysis figures submitted by all state pollution control boards between 2015 and 2016. The State Pollution Control Boards evaluated 275 rivers across 29 states through 1,275 monitoring stations on the basis of their biochemical oxygen demand – the concentration of oxygen required for sustaining aquatic life – under the National Water Quality Monitoring Programme.

The report found that while Maharashtra had 49 polluted river stretches, including Mithi, Godavari, Bhima, Krishna, Ulhas, Tapi, Kundalika, Panchganga, Mula-Mutha, Pelhar, Penganga and Vaitarna, among others, Assam ranked second at 28, Madhya Pradesh third with 21, Gujarat 20, and West Bengal 17.

The situation is no better in the south where the quantum of water in the main rivers including the Godavari, the Cauvery and the Krishna is much reduced.

Water activist Bolisetty and Satyanarayana from Andhra Pradesh points out, "In the Krishna river, there is no water beyond the Srisailam dam which means that for last 140 kilometres (up to the sea)

The United Nations General Assembly proclaimed 21 March the International Day of Forests (IDF) in 2012. The Day celebrates and raises awareness of the importance of all types of forests. On each International Day of Forests, countries are encouraged to undertake local, national and international efforts to organize activities involving forests and trees, such as tree planting campaigns.

The theme for each International Day of Forests is chosen by the Collaborative Partnership on Forests. The theme for 2017 was Forests and Energy.

Did you know that:

Approximately 883 million people in developing countries are employed in the wood energy sector on a full or part-time basis.

Wood provides the world with more energy than solar, hydroelectric or wind power, accounting for roughly 40% of current global renewable energy supply.

About 50 percent of global wood production is used as energy for cooking, heating, and electricity generation.

For 2.4 billion people, woodfuel means a cooked and more nutritious meal, boiled water, and a warm dwelling.

To celebrate the International Day of Forests and 2017's theme, FAO encouraged everyone to get out into their local forest, park, or other green space, and make a short video explaining how the forest energizes them. Learn more about their video campaign here.

The theme of 2018 celebrations is "Forests and Sustainable Cities". Details will be updated shortly

In a cruel irony, a man credited with reducing incidents of man-animal conflicts, among many other achievements, suffered a tragic death on World Wildlife Day after being attacked by a wild elephant.

On Saturday, Conservator of Forests and director of Nagarhole Tiger Reserve for two years, 45-year-old S Manikandan (IFS) along with other officers had ventured into the forests of Dodda Byranakuppe by the Kabini backwaters to inspect a minor forest fire.

According to reports, the 2001-batch officer was briefing his colleagues when a lone tusker came from behind and charged at the group. Unfortunately, Manikandan lost his balance while trying to escape and was trampled by the jumbo. Another officer in the group, RFO Subramanya, sustained minor injuries.

Doctors at the HD Kote Hospital declared him brought dead. Following his demise, the Karnataka government presented state honours to the departed soul in the presence of senior forest officers. His mortal remains were sent to Madurai.

Manikandan had previously served in the northern districts of Ballari, Bidar, Raichur and had even been part of the BMTC as the conservator and director (IT) in Bengaluru.

He had studied Agricultural Sciences at the Tamil Nadu Agricultural University before pursuing a master’s and then PhD in Agricultural Entomology. Before securing a rank in the IFS, he served as a faculty in the Institute of Wood Science and Technology for a brief period.

Manikandan, who hailed from Tamil Nadu’s Theni district, was a favourite among villagers from the surrounding areas for his efforts to conserve nature and in the process reducing incidents of man-animal conflicts.
