Major U.S. cities are leaking methane (Natural Gas) at twice the rate previously believed

Natural gas, long touted as a cleaner burning alternative to coal, has a leakage problem. A new study has found that leaks of methane, the main ingredient in natural gas and itself a potent greenhouse gas, are twice as big as official tallies suggest in major cities along the U.S. eastern seaboard. The study suggests many of these fugitive leaks come from homes and businesses—and could represent a far bigger problem than leaks from the industrial extraction of the fossil fuel itself.

“This is an issue that people tend to ignore when trying to estimate methane emissions,” says Kathryn McKain, an atmospheric scientist with the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory in Boulder, Colorado, who wasn’t involved in the new research. When compared with the global amount of natural and human-driven methane emissions, she notes, “These emissions are small, but they’re preventable.”

Icelandic memorial warns future: ‘Only you know if we saved glaciers’ / The Guardian

Plaque marking Okjökull, the first glacier lost to climate crisis, to be unveiled in August.

The first of Iceland’s 400 glaciers to be lost to the climate crisis will be remembered with a memorial plaque – and a sombre warning for the future – to be unveiled by scientists and local people next month.

The former Okjökull glacier, which a century ago covered 15 sq km (5.8 sq miles) of mountainside in western Iceland and measured 50 metres thick, has shrunk to barely 1 sq km of ice less than 15 metres deep and lost its status as a glacier.

Can planting trees save our climate?

In recent weeks, a new study by researchers at ETH Zurich has hit the headlines worldwide (Bastin et al. 2019). It is about trees. The researchers asked themselves the question: how much carbon could we store if we planted trees everywhere in the world where the land is not already used for agriculture or cities? Since the leaves of trees extract carbon in the form of carbon dioxide – CO2 – from the air and then release the oxygen – O2 – again, this is a great climate protection measure. The researchers estimated 200 billion tons of carbon could be stored in this way – provided we plant over a trillion trees.

The media impact of the new study was mainly based on the statement in the ETH press release that planting trees could offset two thirds of the man-made CO2 increase in the atmosphere to date. To be able to largely compensate for the consequences of more than two centuries of industrial development with such a simple and hardly controversial measure – that sounds like a dream! And it was immediately welcomed by those who still dream of climate mitigation that doesn’t hurt anyone.

Unfortunately, it’s also too good to be true.

The ‘Historical Jigsaw of Climate Deception’: Private Notes Show How Big Oil Spread Climate Science Denial: DESMOG

EXXON & climate change
We’ve all heard the dodgy arguments: ‘the science is uncertain’, ‘climate change is natural, not down to humans’, ‘science has been hijacked by politics’… Now a new cache of documents sheds light on the origins of the disinformation.  

In another verse of a now familiar refrain, a fossil fuel industry group in the 1990s publicly promoted arguments to undermine confidence in climate science while internally acknowledging their products were driving up temperatures.  

A cache of meeting minutes, briefings, and emails uncovered by the Climate Investigations Center shows how industry group the Global Climate Coalition (GCC) used its financial clout and political connections to cast doubt on mainstream climate science until its disbandment in 2002. The GCC would for decades cast doubt on the veracity of climate science and strategically spread the message that the UN Intergovernmental Panel on Climate Change (IPCC) was a politicised body, to discourage regulatory reform that would hit coalition members’ profits.
