Comments Off on Scientists say mass extinction warning signs exist and they can be observed today

Is Earth staring down a mass extinction ? Recent research from an international team of scientists reveals warning signs for the biggest mass extinction in our planet’s history were apparent far earlier than experts had thought — and we can glimpse such indicators now. Around 250 million years ago, the Permian-Triassic mass extinction saw about 90 percent of animal species eradicated, according to the University of Erlangen-Nürnberg in Germany, which led the research team. Huge volcanic eruptions and resulting greenhouse gas emissions wiped out scores of creatures. And for decades, scientists thought this so-called mother of all disasters occurred without warning “when seen on a geological time-scale,” the university said. This new research challenges that opinion.

Multiple species of ammonoids, an  extinct group of marine animals, died off and surviving ones “became increasingly smaller in size and less complex” as time marched towards the mass extinction event, according to the university. Factors that led to the event are reminiscent of conditions today, according to professor and lead author Wolfgang Kiessling, who said in the statement, “There is much evidence of severe global warming, ocean acidification , and a lack of oxygen. What separates us from the events of the past is the extent of these phenomena. For example, today’s increase in temperature is significantly lower than 250 million years ago.” Even so, warning signs that were present near the Permian Period’s end can be seen in modern times, according to the university. Kiessling said, “The increased rate of extinction in all habitats we are currently observing is attributable to the direct influence of humans, such as destruction of habitat, over-fishing, and pollution. However, the dwarfing of animal species in the oceans in particular can be quite clearly attributed to climate change . We should take these signs very seriously.” Geology published the work earlier this year; scientists from institutions in Germany, the United Kingdom, and Iran contributed. + University of Erlangen-Nürnberg + Geology Images via Dieter Korn

China reports meeting its 2020 carbon intensity goals three years early

Comments Off on China reports meeting its 2020 carbon intensity goals three years early

Xie Zhenhua, China ‘s top climate official, has reported that the country has met its 2020 carbon intensity target three years earlier than expected. China’s carbon intensity, as measured by the amount of carbon dioxide produced per unit of economic growth, has decreased by 46 percent since 2005. Such changes in China’s energy economy bode well for a global community that is struggling to meet its obligations under the Paris Agreement . If China, the world’s largest consumer of fossil fuels, can continue its progress towards a carbon-free economy, the nation of nearly 1.5 billion may be well-positioned to support other countries in their efforts to stop catastrophic climate change. In 2009, China set its goal of reducing its carbon intensity by 40 to 45 percent of its 2005 carbon levels. This initial concession towards a less carbon -intense economy helped to set the stage for the successful negotiations of the Paris Agreement. At the time, China also made a commitment to set up a national cap-and-trade system by which emissions would be reduced through market forces. Thus far, it has been unable to establish a functional emissions market. Related: Less fertilizer, greater crop yields, and more money: China’s agricultural breakthrough The cap-and-trade system has also been hindered by technical difficulties and a lack of reliable emissions data. The current scheme, which launched in late 2017, involves only the power sector. As the country attempts to develop its cap-and-trade regime, it also must confront challenges created by a major bureaucratic change that transferred the responsibility for climate change from the National Development and Reform Commission (NDRC) to the Ministry of Ecology and Environment. “It is questionable whether in the short term [the new ministry] can be elevated in status and power to the extent that it will be able quickly to assume the influential role that the NDRC occupied in the area of climate change ,” Peter Corne, a managing partner at the Shanghai legal firm Dorsey & Whitney, told Reuters . Nonetheless, China is making progress and that is good news for all of us. Via Reuters Images via Depositphotos (1)

Extreme fossil fuel financing has surged to $115BN under Trump

Comments Off on Extreme fossil fuel financing has surged to $115BN under Trump

Financing for extreme fossil fuels  like tar sands  swelled in 2017 under Trump, according to a new report.  Banking on Climate Change 2018  tracks 36 of the largest banks in the world to discover they poured $115 billion into these polluting projects, up 11 percent from 2016, according to the Rainforest Action Network (RAN). Coal mining and power, Arctic and ultra-deepwater oil, and liquefied natural gas export are among the extreme fossil fuels covered by the report, endorsed by more than 50 groups — but the tar sands sector leaped ahead of the pack, overtaking coal to become the most heavily backed extreme energy sector. From 2016 to 2017, financing increased by 111 percent, and banks poured almost $47 billion into tar sands. Related: Here’s every bank funding the Dakota Access Pipeline, and how to switch Organizations including RAN, BankTrack , Oil Change International , Honor The Earth , Indigenous Environmental Network , and Sierra Club , graded banks worldwide on their financing, and found JPMorgan Chase was the number one Wall Street funder of these polluting fuels. That institution, along with the Royal Bank of Canada and Toronto Dominion Bank, passed what RAN described as coal-heavy Chinese banks to be extreme fossil fuels’ biggest bankers in 2017. According to RAN’s statement, “JPMorgan Chase increased funding to coal mining by a shocking 21 times and quadrupled its financing of tar sands oil.” Multiple European banks pledged to reduce financing for fossil fuels like shale or oil sands, according to The Independent , but the report revealed banks in North America, especially in Canada, increased funding. “Every single dollar that these banks provide for the expansion of the fossil fuel industry is a dollar going to increase the climate crisis ,” Oil Change International executive director Stephen Kretzmann said in a statement. “The World Bank, which understands the deep threat that climate change poses to poverty alleviation, has gotten the message and is ending its financing of upstream oil and gas projects. Meanwhile, it seems some commercial banks appear intent on going in the opposite direction. It’s time banks like Chase and TD and US Bank took the World Bank’s lead and stop funding fossils. Until they do, these banks will be complicit in our climate catastrophe.” Find out how your bank stacks up in the Banking on Climate Change 2018 report on RAN’s website. + Banking on Climate Change 2018 + Rainforest Action Network Via The Independent Images via Depositphotos and Backbone Campaign on Flickr

The Sixth Mass Extinction of Fauna and Flora is Imminent, Duke University Study Reveals

Comments Off on The Sixth Mass Extinction of Fauna and Flora is Imminent, Duke University Study Reveals

A new study has revealed that extinction rates for plants and animals are currently 1,000 times higher than they were before humans arrived. The rate is so high, in fact, that the planet hasn’t seen anything like it since the dinosaurs were wiped out in a mass extinction event 65 million years ago. If we don’t take measures to address the situation , the lead scientist for the project, biologist Stuart Pimm of Duke University , says that we are heading for a sixth mass extinction .
