    Research team detects an acceleration in the 25-year satellite sea level record | PHYS.org

    Global sea level rise is not cruising along at a steady 3 mm per year, it's accelerating a little every year. The rate is increasing by about 0.08 mm/year every year—which could mean an annual rate of sea level rise of 10 mm/year, or even more, by 2100. This acceleration is driven mainly by accelerated melting in Greenland and Antarctica. It has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate—to more than 60 cm instead of about 30.

    Goodbye, deep sea hydrothermal vents, we hardly knew ye.
    This is why we can't have good stuff.

    Mining companies worldwide are set to start pulverizing the Earth's hydrothermal vents, so's they can grub out the concentrated heavy metals, rare-earth metals, precious metals and any other profitable stuff they can then use to make more doo-dads for us.

    These vents are the actual 'Gardens of Eden' so to speak. Abiogenesis - Wikipedia https://en.wikipedia.org/wiki/Abiogenesis#Deep_sea_vent_hypothesis

    The earliest known life forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 billion years ago, not long after the oceans formed 4.41 billion years ago, and not long after the formation of the Earth 4.54 billion years ago.

    When one Flies to a far away destination for Ecotourism, then Heli fishing is a must do too of course . . . o_O

    Wow, you KNOW you have too much money when you use a gas guzzling $600 and hour machine to hunt a kilo of animal meat worth $26 per kilo.

    Is it worse than hunting Giraffes and Lions. ?

    Then there are people going to jail for their grandkids - turning off oil pipelines.

    But as has been said on this thread before "Its anti-patriotic to let out country thrive"

    I guess the Earth and it's oceans don't have enough resources for us. The trials and tribulations of being Earth's apex predator are endless, now we're privatizing the moon.

    Not a bad idea.
    At least the Moon and asteroids don't have fragile, biological systems to destroy.

    Its a shame that the rockets dump 440 tonnes of Co2 into the atmosphere on every launch. :-(

    Arctic temperatures soar 45 degrees above normal, flooded by extremely mild air on all sides | Washington Post

    While the Eastern United States simmers in some of its warmest February weather ever recorded, the Arctic is also stewing in temperatures more than 45 degrees above normal. This latest huge temperature spike in the Arctic is another striking indicator of its rapidly transforming climate.

    Temperatures over the entire Arctic north of 80 degrees latitude have averaged about 10 degrees (6 Celsius) above normal since the beginning of the calendar year, sometimes spiking over 25 degrees (14 Celsius) above normal (the normal temperature is around minus-22, or minus-30 Celsius).

    Global sea ice is at lowest level ever recorded | New Scientist

    It’s a new low point. The area of the world’s oceans covered by floating sea ice is the smallest recorded since satellite monitoring began in the 1970s. That means it is also probably the lowest it has been for thousands of years.

    In the Arctic, the low in sea ice coverage is a result of both global warming and unusual weather events probably influenced by global warming. But in the Antarctic, the current low in seasonal sea ice could just be a result of natural variability.

    Climate change is imperiling half of all U.S. military sites globally | Think Progress

    A new study from the Pentagon reveals that almost half of all U.S. military sites are threatened by climate change. The findings stand in stark contrast to the White House’s position on global warming and climate science.

    Around 1,700 sites around the world, ranging from outposts to large bases, are imperiled by drought, wind, and flooding, the Pentagon study reveals. The report is the first investigation into the impact “a changing climate” might have on at least 3,500 U.S. military spaces.

    Committed sea-level rise under the Paris Agreement and the legacy of delayed mitigation action | Nature Communications

    Abstract

    Sea-level rise is a major consequence of climate change that will continue long after emissions of greenhouse gases have stopped. The 2015 Paris Agreement aims at reducing climate-related risks by reducing greenhouse gas emissions to net zero and limiting global-mean temperature increase. Here we quantify the effect of these constraints on global sea-level rise until 2300, including Antarctic ice-sheet instabilities. We estimate median sea-level rise between 0.7 and 1.2 m, if net-zero greenhouse gas emissions are sustained until 2300, varying with the pathway of emissions during this century. Temperature stabilization below 2 °C is insufficient to hold median sea-level rise until 2300 below 1.5 m. We find that each 5-year delay in near-term peaking of CO2 emissions increases median year 2300 sea-level rise estimates by ca. 0.2 m, and extreme sea-level rise estimates at the 95th percentile by up to 1 m. Our results underline the importance of near-term mitigation action for limiting long-term sea-level rise risks.

    Even Oil Companies Are Now Saying Climate Change Will Hurt Their Business |TIME

    In its annual energy outlook released last week, BP said that it expected oil demand to peak in the next two decades as renewable energy grows and consumers purchase hundreds of millions of electric vehicles. In an outlook released in February, Exxon Mobil projected a peak in demand for gasoline in the coming decades and acknowledged that some of its assets “may not be attractive investments” as a result of the shifting energy market.

    “The recognition of the energy transition has grown over the past year with the oil and gas players,” says Marie-Helene Ben Samoun, managing director of the Boston Consulting Group’s oil and gas practice. “They are not only acknowledging global warming, but they are also acknowledging the energy transition and the impact on their own portfolio.”

    Oil companies lamenting about climate change impacting their portfolios. They are victims, not perpetrators. Sure, that makes sense.

    These starfish should have moved to a better climate. Apparently they are too lazy.
