    Climate change is 'escalator to extinction' for mountain birds | BBC

    Researchers have long predicted many creatures will seek to escape a warmer world by moving towards higher ground.

    They are particularly concerned about tropical mountain ranges, as the difference in temperatures between lower and higher elevations in tropical regions is not as great as it is in other parts of the world.

    The study found that most of the species that had been found at the highest elevations declined significantly in both range and abundance.

    The ones that lived near the top of Peruvian mountains 30 years ago are gone.

    The study was published in the Proceedings of the National Academy of Sciences.

    Global Warming Still On Track For 4°C Despite Strong Carbon Prices, According To Schroders | Clean Technica

    The cost of carbon in Europe has soared to its highest levels for almost a decade, from €8 per tonne (t) a year ago to €24/t by the end of September 2018, but it has not been enough to slow the pace of global warming, according to Schroders’ latest Climate Progress Dashboard update, which remains on track for 4°C.

    Schroders estimate prices will need to rise as far as $100 per tonne to meet long-term emissions reduction targets.

    The higher carbon prices are countered by increased investment in the oil and gas industries.

    Schroders explains that scientific studies have shown what a 4°C rise would look like in practical terms, including:
    • Global crop yields would fall 30-40% below current levels on average.
    • Up to 300 million people would be affected by coastal flooding.
    • One-third of the world’s population would face water shortages.
    • Global economic losses could build to $23 trillion over the next 80 years; equal to permanent damage three or four times the scale of the 2008 Global Financial Crisis, and continuing to escalate.

    Dangerous climate change is likely, concludes research | PHYS.org

    A study says that sensitive regions of the world are still at risk from the dangerous and potentially irreversible effects of climate change; even if we meet the target of not increasing global temperature above 1.5°C over the next 100 years.

    The research also concludes that meeting the target set by the 2015 Paris Climate Agreement of limiting the increase in global average temperatures to well below 2°C does not depend on future generations to remove vast amounts of carbon from the Earth's atmosphere. Instead, governments can achieve the goals through emission reductions.

    The study was published in Nature Climate Change.

    Human "fingerprints" detected in planet's changing seasons | Axios

    Human activities are altering Earth's seasons in a way that is creating a greater contrast between summer and winter in much of North America, Europe and Eurasia, a new study finds.

    Summers are warming faster than winters in the northern and southern midlatitudes, leading to a greater contrast between the hottest and coldest times of year.

    An exception to this is at the highest latitudes, where the difference is actually decreasing, which is related to the loss of Arctic sea ice in the far north, and ozone depletion above Antarctica.

    Interestingly, the findings run counter to surface temperature trends in northern midlatitudes, which show that winters are warming faster than summers, which is a discrepancy that has yet to be fully explained.

    The study was published in Science.

    IEA warns of 'worrying trend' as global investment in renewables falls | The Guardian

    The International Energy Agency has sounded the alarm over a “worrying” pause in the shift to clean energy after global investment in renewables fell 7% to $318bn (£240bn) last year, a trend it expects to continue into 2018.

    Fossil fuels increased their share of energy supply investment for the first time since 2014. Fossil fuels’ share of energy investment needs to drop to 40% by 2030 to meet climate targets.

    Wealthier people do less in the struggle against climate change | EurkAlert

    A collective-risk dilemma experiment was conducted among the public in Barcelona showed that people are more or less likely to contribute money to fighting climate change depending on their how wealthy they are. Participants with fewer resources were prepared to contribute significantly more to the public good than wealthier people, sometimes up to twice as much.

    The results suggest that future policies could be improved if they reinforced climate justice actions in favour of the most vulnerable people and taught the importance of fairness rather than focusing on teaching people about generic or global climate consequences, as the latter have not been proven to lead to equitable contributions.

    The study demonstrates once again that cooperation is better than competition at achieving socially desirable outcomes and that, in the case of climate change, cooperation is needed between all of the agents involved.

    The study was published in PLOS ONE.

    Y Combinator’s Search For a Climate Change Unicorn | Singularity Hub

    Silicon Valley’s premier tech incubator, Y Combinator, has put out a call for proposals for technology that can make a major difference in combating climate change.

    They are looking to fund improbable moonshots with a high likelihood of failure, but potentially massive returns. They've identified four potential areas of interest:

    • Plants are the planet’s best carbon-fixers, but huge swathes of the ocean are almost entirely devoid of them. Can the key nutrients required to carry out photosynthesis be added to the oceans, or could phytoplankton be genetically engineered so it doesn’t require the nutrients?
    • Nature already sequesters about one billion metric tons of CO2 every year through a process called mineral weathering. Could that process be accelerated by using renewable energy to carry out electrolysis on saline water, which produces both hydrogen fuel and a highly reactive solution that can trap CO2 in minerals?
    • Can the enzymatic pathways the microbes use to convert CO2 into other useful compounds be isolated in bioreactors to increase the speed of the process?
    • Could desert areas be flooded with (sea?) water to make shallow lakes supporting CO2-fixing algal beds?

    Climate change is scary. 'Rat explosion' is way scarier. | Ottawa Citizen

    Many living things are sensitive to small changes in temperature, so warming of 2 degrees Celsius will transform the flora and fauna that surround us in a big way.

    Warmer winters will continue to dial up rat fecundity. People in urban areas such as New York and Boston are already noticing a lot more rats, not just in downtown alleyways, but even in the posh suburbs.

    Biologists have calculated that populations of dangerous crop-eating insects are likely to explode as temperate areas warm, reducing crop yields by 25 to 50 percent. Similarly, biologists have found that warming oceans have allowed a population explosion of purple sea urchins – “cockroaches of the ocean” — which are choking out other denizens of Pacific kelp forests.

    Giant 'waves' in the sky wreak havoc on our weather, study says | USA Today

    A new study says climate change is causing the jet stream to slow down, stall and meander in strange ways.

    "If the same weather persists for weeks on end in one region, then sunny days can turn into a serious heat wave and drought, and lasting rains can lead to flooding," said study co-author Stefan Rahmstorf.

    The extreme and unusual jet stream patterns – known technically as "quasi-resonant amplification" – could increase by as much as 50 percent by 2100.

    That sounds ominous.

    The rat explosion thing is comparable to the human population bomb thing, except the rats are far less capable of mass destruction. They both seem about as mindless as one another, though.

    The bright side...

    It will be tough to eat them because they are so darn cute, but it will allow us humans to survive and produce more r̶a̶t̶s̶ children.

    A couple of videos by the liberal redneck Trae Crowder about climate change. Those who get offended by language should turn the sound off and close your eyes to watch it. The first is from 2016, the second is from a few weeks ago...

    Yeah, the article's from the Bloomberg business and financial place, I won't bother with a site link.

    I wonder what yellow tinted arguments deniers are going to use to turn it around and blame the 97% for climate change. Or how many deniers will deny they denied. Who, me? I never denied it and I never voted for Spanky either.

    The combined agencies of the DOA, DOC, DOD, DOE, HHS, DOI, DOS, DOT, EPA, NASA, NSF, Smithsonian Institution, and the USAID released their Fourth National Climate Assessment Friday, a month early. It was also the day of the annual Black Friday Mindless Consumer Slop Fest. Since it's of no concern here in the US where we know better, that was extremely thoughtful of the administration to hurry up the release to a day when folks are not paying attention to the news, and spare us the bother of dealing with fake news facts.

    Big oil, the taxpayer subsidized For-Profit business, the creator of climate change and a massive source of funding for climate change denial pseudo-science, says they need billions of taxpayer dollars to protect their assets from climate change. It's more than likely the truth that their operations are threatened by climate change, and it's more than likely the US will provide the billions they are saying will be needed. They also want legislation giving them indemnity from problems caused by climate change.

    Today on NPR the discussion was that rising oceans are a somewhat far off problem, in the much nearer future agriculture will suffer massive problems.

    It's too bad politics can't be discussed here. The US is being destroyed day by day.

    OK, so over on the Wooden Boat forums....
