    The combination of greenhouse gas emissions and the hot air coming from the White House is leading to dire consequences for our planet.

    US greenhouse gas emissions spiked in 2018
    The Washington Post, Jan 8 2019 4:20 AM

    US carbon dioxide emissions rose an estimated 3.4% in 2018, according to new research — a jarring increase that comes as scientists say the world needs to be aggressively cutting its emissions to avoid the most devastating effects of climate change. The findings, published today by the independent economic research firm Rhodium Group, mean that the United States now has a diminishing chance of meeting its pledge under the 2015 Paris climate agreement to dramatically reduce its emissions by 2025.

    The findings also underscore how the world's second-largest emitter, once a global leader in pushing for climate action, has all but abandoned efforts to mitigate the effects of a warming world. President Trump has said he plans to officially withdraw the nation from the Paris climate agreement in 2020 and in the meantime has rolled back Obama administration regulations aimed at reducing the country's carbon emissions. The sharp emissions rise was fueled primarily by a booming economy, researchers found. But the increase, which could prove to be the second-largest in the last 20 years, probably would not have been as stark without Trump administration rollbacks, said Trevor Houser, a partner at Rhodium.

    Here is the latest dire news for our planet -- news which our President will ignore and dismiss:

    Oceans are warming dramatically faster, new study warns
    CBS News, Jan 11 2019 7:54 PM

    A new study finds the world's oceans are warming significantly faster than previously thought. The analysis, published Thursday in the journal Science, raises the stakes for curbing climate change. Since 1970, the ocean has warmed 40% more than previous estimates, according to climate scientist Zeke Hausfather, one of the authors of the study.

    The study examined four new or updated Ocean Heat Content records — a fancy term for measuring how warm the ocean is, taking into account deeper water, not just surface temperatures — and finds the ocean warming is significantly higher than estimated in the last comprehensive report by the UN's Intergovernmental Panel on Climate Change in 2013. Ninety-three percent of the excess heat trapped in the earth's system by human-caused greenhouse gas emissions is stored in the oceans. If it weren't for this ocean buffer absorbing so much heat, our atmosphere would be roasting us by now.

    I wonder how many cities would still be above sea level if the oceans rose 188 feet -- and would Denver, Omaha and Wichita become coastal communities?

    Antarctica ice melt has accelerated by 280% in the last four decades
    Brandon Miller, CNN, Jan 14 2019 4:15 PM

    A new study published today in the Proceedings of the National Academy of Sciences reveals that our planet's ice is melting at an alarming rate, which is bad news for global sea levels. According to the study, led by Eric Rignot from the University of California at Irvine, which looked at details of ice and snow from the entire continent of Antarctica since 1979, Antarctica's crucial ice sheet has been melting for the entire 39 year period. The rate of that ice loss has not been consistent, with ice disappearing faster in each successive decade, from 40 gigatons per year from 1979-90 all the way up to 252 gigatons per year from 2009-17, a six-fold increase. That melt-rate has been accelerating in the most recent decades, up 280% in the second half of the nearly 40 years compared to the first half.

    The continent holds a majority of the planet's ice and, if melted, would cause the average sea level to rise 188 feet. "If we fail to achieve carbon dioxide emissions targets and earth's average temperature warms more than 2° Celsius, sea ice will diminish," said Richard Levy of New Zealand's GNS Science & Victoria University of Wellington. Currently, Antarctica's sea ice is at the lowest January levels since detailed observations began in 1979, according to data from the US National Snow & Ice Data Center.
