SAN FRANCISCO (Reuters) - Lyft Inc is launching a program on Thursday to offset emissions from the 1.4 million cars that drive for the U.S. ride-hailing service by investing in projects to reduce other sources of greenhouse gas, the company said.

Shipping industry agrees to halve carbon emissions by 2050: IMO 14.4.2018 General News
Members of the UN International Maritime Organisation today struck a deal to halve carbon dioxide emissions from shipping by 2050 in a deal that will force the industry to redesign fleets. "The initial strategy envisages for the first time a reduction in total GHG (Greenhouse Gas) emissions by at least 50 percent by 2050 compared to 2008," the London-based IMO said in a statement.

Over 170 countries agree to reduce shipping emissions by 2050 14.4.2018 General News
Over 170 countries, comprising India, on Friday reached a historic agreement in London to reduce shipping carbon dioxide emissions by "at least" 50 per cent on 2008 levels by 2050 with an emphasis on scaling up action to 100 per cent by the mid-century.

Mountain erosion may add CO2 to atmosphere: study 13.4.2018 General News
The process of mountain erosion can be a source of new carbon dioxide gas that can release it back into the atmosphere far faster than it is being absorbed into newly exposed rock, a study has found. The source of this extra CO2 is not entirely geological. Instead, it is the byproduct of tiny microbes in mountain soils that "eat" ancient sources of organic carbon that are trapped in the rock, researchers at Woods Hole Oceanographic Institution in the US said. As the microbes metabolise these minerals, they spew out carbon dioxide, they said. "This goes against a long-standing hypothesis that more mountains mean more erosion and weathering, which means an added reduction of CO2," said Jordon Hemingway, a postdoctoral fellow at Harvard University. "It turns out it is much more complicated than that," said Hemingway, lead author of the research paper published in the journal Science. The researchers came to this realisation after studying one of the most erosion-prone mountain chains in .

These Arctic foxes turned blue Arctic foxes are endangered in Sweden, Norway and Finland, scattered in isolated populations that can fall victim to severe inbreeding. Thats what happened to a group descended from six white foxes that settled in the early 2000s on Helagsfjället, a mountain in southern Sweden. But in 2010, a local ranger noticed something different: blue Arctic foxes. The immigrants presented a rare opportunity for scientists to study what happens when new genetic material flows into a small, isolated population threatened with extinction. In a study published in Proceedings of the Royal Society B, scientists from Sweden and Norway reported that just three new males dramatically reduced inbreeding and produced a generation of more robust offspring in the Helagsfjället Arctic fox population. The blue foxes that arrived in Helagsfjället had come from a captive breeding and restoration programme funded by the Norwegian government. In 2009, the ...

New source of global nitrogen discovered 9.4.2018 General News
Over a quarter of nitrogen on Earth comes from the planet's bedrock, according to a study that could greatly improve climate change projections. For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. The study, published in the journal Science, found that up to 26 per cent of the nitrogen in natural ecosystems is sourced from rocks, with the remaining fraction from the atmosphere. Before this study by researchers at the University of California - Davis in the US, the input of this nitrogen to the global land system was unknown. The discovery could greatly improve climate change projections, which rely on understanding the carbon cycle. This newly identified source of nitrogen could also feed the carbon cycle on land, allowing ecosystems to pull more emissions out of the atmosphere, the researchers said. "Our study shows that nitrogen weathering is a globally significant source of nutrition to soils and ...

How climate change could impact food shortage 2.4.2018 General News
Food insecurity risks could increase with weather extremes caused by climate change, suggests a study.Researchers at University of Exeter examined how climate change could affect the vulnerability of different countries to food insecurity - when people lack access to a sufficient quantity of affordable, nutritious food.Scientists looked at the difference between global warming of 1.5°C and 2°C (compared to pre-industrial levels) and found that - despite increased vulnerability to food insecurity in both scenarios - the effects would be worse for most countries at 2°C.The study looked at 122 developing and least-developed countries, mostly in Asia, Africa and South America."Climate change is expected to lead to more extremes of both heavy rainfall and drought, with different effects in different parts of the world," said Professor Richard Betts, Chair in Climate Impacts at the University of Exeter."Such weather extremes can increase vulnerability to food insecurity."Some change is ...

Chocolate production may be harming environment: study 2.4.2018 General News
Your favourite chocolates may be significantly harming the environment, say scientists who found that the UK chocolate industry produces about 2.1 million tonnes of greenhouse gases in a year. A study, published in the journal Food Research International, looked at the carbon footprint of chocolate and its other environmental impacts. Researchers from the University of Manchester in the UK assessed the impact of ingredients, manufacturing processes, packaging and waste. The study estimates that the UK chocolate industry produces about 2.1 million tonnes of greenhouse gases a year. This is equivalent to the annual emissions of the whole population of a city as large as Belfast. It also found that it takes around 1,000 litres of water to produce just one chocolate bar. On average, each person individually consumes about eight kilogramme of chocolate per year, researchers said. They found the raw materials used to produce chocolate as well as the packaging are the major environmental ...

US on track to meet climate targets despite Donald Trump pulling out of accord: UN chief 30.3.2018 DNA: Mumbai
The United States is on track to meet the targets of the Paris climate agreement despite President Donald Trump's plan to withdraw from the accord, UN Secretary-General Antonio Guterres said today. Guterres said emissions-cutting plans put in motion by American businesses, regional governments and cities meant that the goals set by the former US administration which signed the deal in 2016 were within reach. "We have seen in the cities, and we have seen in many states, a very strong commitment to the Paris agreement, to the extent that some indicators are moving even better than in the recent past," Guterres told reporters at UN headquarters in New York. "There are expectations that, independently of the position of the administration, the US might be able to meet the commitments made in Paris as a country." Under the deal, the administration of former president Barack Obama pledged to cut domestic greenhouse gas emissions 26 to 28 percent below 2005 levels by 2025. Nearly 200 countries and parties have ...

Land decay to displace tens of millions, global survey warns 26.3.2018 General News
Land degradation will unleash a mass migration of at least 50 million people by 2050 -- as many as 700 million unless humans stop depleting the life-giving resource, dozens of scientists warned today. Already, land decay caused by unsustainable farming, mining, pollution, and city expansion is undermining the well-being of some 3.2 billion people -- 40 per cent of the global population, they said in the first comprehensive assessment of land health. The condition of land is "critical," said the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). "We've converted large amounts of our forests, we've converted large amounts of our grasslands, we've lost 87 percent of our wetlands... we've really changed our land surface in the last several hundred years," IPBES chairman Robert Watson said of the findings. "The message is: land degradation, loss of productivity of those soils and those vegetations will force people to move. It will be no longer viable
