"A new study of UK lake sediment records stretching back over several centuries has found that the floods that hit Northern England in 2009 and 2015 ('Storm Desmond'),were the largest in 600 years, pointing to the impact of climate changes on the frequency and magnitude of these extreme events.
In a paper published in the journal `Earth Surface Processes and Landforms', a team of researchers led by the Universities of Liverpool and Southampton, analysed the lake sediment records from the extreme floods of 2009 and 2015, and compared them with a 558 year record from the bottom of Bassenthwaite Lake, Cumbria.
A distinct layer of coarser sediment is left in the lake sediment record as material washes in from the surrounding hills and streams providing researchers with a means of recording each flooding event. Sediment layers with the largest grain sizes reflect flooding that was higher energy and more extreme in magnitude.
This is the first time a long term insight into the changing frequency and size of flood events has been produced using lake sediment records for the UK, and it shows how these archives can extend river flows used in conventional flood estimation, which only span relatively short period of 30-50 years.
Richard Chiverrell, Professor of Physical Geography with the University of Liverpool's School of Environmental Sciences and lead author of the study, said: "This research study places recent the extreme flooding events of the last 20 years in a far longer context, providing new insights into the frequency and magnitude of the really large flood events."
(The unprecedented nature of the recent phase of extreme floods accords with statements from the Environment Agency that climate changes and associated impacts on the frequency and magnitude of extreme events are one of the greatest challenges facing our society)."

"Soil health improvement, a technique known as carbon farming, could cut the amount of carbon dioxide in the Earth’s atmosphere by more than one-sixth, a US business group says.
It says a concerted effort by the world’s farmers to restore and protect soil health could reduce atmospheric carbon dioxide by as much as 65 parts per million (ppm) from its current level of more than 415 ppm.
It made the announcement at a webinar on carbon farming which it hosted here in April. A full report of the webinar appears on the website of the The Energy Mix.
The group, the US-based Environmental Entrepreneurs (E2), describes itself as “a national, nonpartisan group of business leaders, investors, and professionals from every sector of the economy who advocate … smart policies that are good for the economy and good for the environment”
World leaders … said that regenerative agriculture to naturally conserve and protect topsoil and support its fertility and resilience were “a huge carbon capture opportunity”
The total saving of 65 ppm represents the estimated amount of carbon that human activity has removed from the soil since the dawn of industrial agriculture.
But, E2 says, even if its eventual contribution to climate stabilisation falls well short of this figure, drawing attention to soil carbon sequestration could still concentrate minds on a climate solution often neglected in comparison with more complex and often riskier options for emission cuts.
E2 says a critical step in advancing climate-friendly soil health in the US is the ground-breaking Soil Health Demonstration Trial, a carbon farming pilot project that a coalition of farmers, agricultural technology entrepreneurs and environmentalists managed to persuade a deeply divided US Congress to accept in the December 2018 farm bill, the Agricultural Improvement Act of 2018.
The idea for the carbon farming pilot emerged in the wake of the UN’s 2016 annual climate conference, known as COP23, held in the German city of Bonn. World leaders there said that regenerative agriculture to naturally conserve and protect topsoil and support its fertility and resilience were (a huge carbon capture opportunity)”.

"Climate change and rising sea levels eventually may wipe out one of the world’s last and largest tiger strongholds, scientists warned in a new study.
The cats are among nearly 500,000 land species whose survival is now in question because of threats to their natural habitats, according to a report on Monday by the United Nations.
The Sundarbans, 4,000 square miles of marshy land in Bangladesh and India, hosts the world’s largest mangrove forest and a rich ecosystem supporting several hundred animal species, including the endangered Bengal tiger.
But 70 percent of the land is just a few feet above sea level, and grave changes are in store for the region, Australian and Bangladeshi researchers reported in the journal Science of The Total Environment. Changes wrought by a warming planet will be “enough to decimate” the few hundred or so Bengal tigers remaining there".

'The battle against #ClimateChange' [is already lost]
The documents include hundreds of briefings, meeting minutes, notes, and correspondence from the Global Climate Coalition (GCC). They were released Thursday by the Climate Investigations Center in collaboration with DeSmog and Climate Liability News. The documents date from 1989 and continue through 2002, when the lobbying group disbanded as its fossil fuel industry backers succumbed to public pressure to disavow its tactics.
GCC representatives regularly met with IPCC scientists to lobby the panel to accept industry language in its reports, the documents show. Tax returns show hundreds of thousands of dollars spent on an “IPCC Tracker Fund” to monitor and lobby the IPCC’s meetings.

In #Norway there have been two large wildfires in the woodlands. One in #Lyngdal in Vest-Agder area is under control, while the one in #Sokndal in #Rogaland is ongoing with wind gusts in this area up to minimum gale force. Between 3,000 and 4,000 "mål" wood are burned down in the first area, a mål is about 1,000 square meter. In the second area, 148 flats were evacuated and it is expected that more will be necessary.

(me) Would you say Al Gore uses pseudoscience?
Northern Invader (email@example.com)
... our current existential climate threat. If anything he [Al Gore] has understated the immediacy of the threat of #climatechange.
I was wondering how you justify the following points?
Al Gore’s new book and movie, both titled An Inconvenient Truth, have been hailed by environmentalists–despite being filled with false or misleading claims about the science of global warming and related issues. This page details errors in the book (2006, Rodale Books), which in summary include:
* Misleading links between weather events and climate change: Climate is the average of weather conditions over long time periods; because the climate system is inherently variable, individual weather events are not indicative of trends. Nonetheless, Gore overwhelms the reader with many individual events, claiming this is global warming in action: a European heatwave, record daily highs in U.S. cities one summer, hurricane Katrina, floods in Europe and China, and more. To address the issue of climate change, all such events must be considered over time. As it turns out, in several cases such analysis refutes any claims of recent trends (for example, with regard to floods).
- In other cases, the scientific community is engaged in much research and debate. Gore claims that there is “an emerging consensus” that hurricane activity is on the upswing due to global warming. The reality is that this is the subject of much debate in the scientific community: different researchers have produced contradictory conclusions, but the factors involved are far more complex than Gore admits, and research is continuing.
- These aren’t the only cases of sloppiness with data: Gore claims the hottest year on record was 2005, but in reality existing observations don’t have the accuracy to discriminate between, say, 2005 and 1998, a hot year due to an extreme El Nino event. He claims that the increasing closures of the barrier’s on Britain’s Thames River show sea level is rising, but doesn’t mention that the British government recently changed the rules for such closures, including closing the barriers to deal with low sea level; and he claims that a particular bird species is “in trouble” in the Netherlands due to climate change, but researchers report no change in this bird population. He cites a peak in tornadoes in 2004 as further evidence, but this peak came from new technology permitting the counting of more weak tornadoes than ever before; comparison of consistent data shows no trends in tornadoes.
- Misleading claims about effects of climate change: Gore claims that the emergence of new diseases is related to global warming, but most of the diseases he lists have little or no relationship to climate. Even in the case of malaria, a disease with a stronger link to climate, health experts cite the management of human infrastructure and health systems as far more important factors. In other cases Gore neglects the strong influence of human resource management, as with linking occurrence of wildfires or pest outbreaks to global warming. He also claims global warming is causing a “significant” number of polar bear drownings, based on a report of four drowned polar bears; however, other researchers report the polar bear population is generally unchanged. Melting of glaciers on Mount Kilimanjaro and in Glacier National Park are cited as consequences of global warming, but in both cases these glaciers have been melting since the 1800s, when the Earth emerged from a period of global cooling.
- False claims about scientific views on global warming: Gore asserts that the scientific community is in essentially unanimous agreement with his interpretation of global warming, and dismisses skepticism of global warming as an energy industry conspiracy. Not only are such claims false, they severely misrepresent the very process of science. Gore cites a flawed editorial from a science journal to claim that all published research agrees with the “consensus” view on global warming; in reality, much published research contradicts Gore’s position on global warming, and a recent survey of climate scientists found the community fairly split on the claim that there is an imminent threat from human-caused global warming. Despite the abundance of scientific research contradicting his position, Gore instead concentrates on refuting a handful of skeptical claims from outside the scientific community–and can’t even get the facts right on those. To add insult to injury, Gore repeatedly impugns the motives of scientists and non-scientists who question his “consensus” on global warming. Rather than confront the scientific facts, he stereotypes the critics and dismisses them based on imagined motives.
- Conceptual errors: Gore’s explanation of several topics, including the greenhouse effect, the relationship of carbon dioxide and global temperature, decline in Arctic Ocean pack ice, structure of the Greenland ice sheet, and ozone depletion, contain conceptual errors. He may indeed have a correct understanding of these issues, but what he communicates serves to perpetuate misconceptions on these subjects. Combined with the low reading level of the text, this tends to convey the lowest expectations of his readers.

"Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study by Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and published in the journal Nature Communications, however, shows that areas of cold permafrost can be vulnerable to rising summer temperatures.
Using a set of satellite images from the Google Earth Engine Timelapse dataset, Professor Lewkowicz and his co-author Robert Way recorded an astounding sixty-fold increase in the number retrogressive thaw slumps - landslides caused by the melting of the ice in the permafrost - on Banks Island over the past three decades. In 1984, there were about 60 active thaw slumps on the island. In 2013, there were more than 4,000, including about 300 initiated within Aulavik National Park. Overall, the area impacted by active slumping is now equivalent to that of the Island of Manhattan.
The analyses show that 85% of new landslides on Banks Island formed after four particularly hot summers (1998, 2010, 2011 and 2012), which caused the topmost layer of the permafrost to thaw. With global warming and rising temperatures, Professor Lewkowicz predicts a further increase in retrogressive thaw slumps: even under a relatively conservative scenario, there could be 10,000 new slumps per decade on Banks Island alone. Since these thaw slumps can keep growing for decades, Lewkowicz calculates that this could mean the island alone could be home to a staggering 30,000 active landslides in any future year".
