    400 PPM: What’s Next for a Warming Planet Concentrations of greenhouse gases in the atmosphere have reached this level for the first time in millions of years. What does this portend? » On May 2, after nightfall shut down photosynthesis for the day in Hawaii, carbon dioxide levels in the atmosphere touched 400 parts-per-million there for the first time in at least 800,000 years. Near the summit of volcanic Mauna Loa—where a member of the Keeling family has kept watch since 1958—sensors measured this record through sunrise the following day. Levels have continued to dance near that benchmark in recent...
  • Greenhouse gas 'detergent' recycles itself in atmosphere

    A simple molecule in the atmosphere that acts as a "detergent" to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change. The hydroxyl (OH) radical, a molecule made up of one hydrogen atom, one oxygen atom with a free (or unpaired) electron is one of the most reactive gases in the atmosphere and regularly breaks down other gases, effectively ending...

    If human-induced climate change continues unchecked, 10 percent of the U.S. economy could evaporate by 2100, a 1,656-page federal report the White House slipped out on Black Friday (Nov. 23) warned but a nearby world has an even hotter climate problem than ours, and scientists say we could learn some valuable lessons from it. That world is Venus, Earth's "evil twin," which was once nice enough until something went wrong and the atmosphere began trapping a little too much heat. Scientists aren't positive precisely how events played out, but the runaway greenhouse effect that resulted is beyond debate:...
  • "State Of Insurrection" As Fuel Tax Riots Engulf Central Paris

    PARIS, Dec 1 (Reuters) - Rioters ran amok across central Paris on Saturday, torching cars and buildings, looting shops, smashing windows and clashing with police in the worst unrest in more than a decade, posing a dire challenge to Emmanuel Macron's presidency. The authorities were caught off guard by the escalation in violence after two weeks of nationwide protests against fuel taxes and living costs, known as the "yellow vest" movement after fluorescent jackets kept in all vehicles in France. In Paris, police said they had arrested almost 300 people while 110 were injured, including 20 members of the security...

    French President Emmanuel Macron made global warming a central part of his World Economic Forum speech on Wednesday in Davos, pledging to close all of his countrys coal-fired power plants by 2021. Macrons anti-coal pledge comes as Ecology Minister Nicolas Hulot announced France failed to meet its 2016 global warming target to limit greenhouse gas emissions to 447 million metric tons. Hulot said France would revise its global warming targets to better align with its Paris climate accord commitment to go carbon neutral by 2050, Reuters reported. Macron has been one of the most vocal supporters of the Paris climate...

    TIME ^ | November 27, 2018 | By JUSTIN WORLAND
    Three years ago, world leaders from nearly every country around the world laid out specific plans to fight climate change that included strategies to slash their greenhouse gas emissions. Those commitments generated optimism that the world might finally address global warming and helped seal the deal on the Paris Agreement. Now, the majority of G20 countries arent following through on their promises, according to a new report from the United Nation Environment Programme. And, even if countries followed through, the world would fall short of limiting temperature rise to safe levels. The backsliding is largely the result of increased economic...

    Environmentalism: A new report calls the lie on the grand Paris climate change treaty. None of the promised cuts in CO2 emissions that 200-plus countries made will come close to preventing a climate "catastrophe." And many of the industrialized nations aren't even living up to the promises they did make.
  • Greenhouse gas levels in atmosphere hit new high: UN

    The levels of greenhouse gases in the atmosphere, the main driver of climate change, have hit a new record high, the UN said Thursday, warning that the time to act was running out. Ahead of the COP 24 climate summit in Poland next month, top United Nations officials are again trying to raise the pressure on governments to meet the pledge of limiting warming to the less than two degrees Celsius, enshrined in the 2015 Paris accord. Without rapid cuts in CO2 and other greenhouse gases, climate change will have increasingly destructive and irreversible impacts on life on Earth, the...

    It may be the last place you'd expect to find corals -- up to 6,000 m (20,000 ft) below the ocean's surface, where the water is icy cold and the light dim or absent. Yet believe it or not, lush coral gardens thrive here. In fact, scientists have discovered nearly as many species of deep-sea corals (also known as cold-water corals) as shallow-water species... deep-sea corals don't need sunlight. They obtain the energy and nutrients they need to survive by trapping tiny organisms in passing currents... living even in waters as cold as -1C (30.2F)... occur in the waters of...

    Environmental officials warned 30 years ago the Maldives could be completely covered by water due to global warming-induced sea level rise. That didnt happen. The Indian Ocean did not swallow the Maldives island chain as predicted by government officials in the 1980s. In September 1988, the Agence France-Presse (AFP) reported a gradual rise in average sea level is threatening to completely cover this Indian Ocean nation of 1196 small islands within the next 30 years, based on predictions made by government officials. Then-Environmental Affairs Director Hussein Shihab told AFP an estimated rise of 20 to 30 centimetres in the next...

    EurekAlert! ^ | November 13, 2018 | Northumbria University
    Rising global sea levels may actually be beneficial to the long-term future of coral reef islands, such as the Maldives, according to new research published in Geophysical Research Letters. Low-lying coral reef islands are typically less than three metres above sea level, making them highly vulnerable to rising sea levels associated with climate change. However, research has found new evidence that the Maldives - the world's lowest country - formed when sea levels were higher than they are today... They found that large waves caused by distant storms off the coast of South Africa led to the formation of the...

    The exploration vessel Nautilus, with a team of experts of the University of Haifas Leon H. Charney School of Marine Sciences, headed by Prof. Zvi Ben Avraham, discovered for the first time an area of reefs with deep-sea corals in the Mediterranean, offshore of Israel. This area apparently stretches over a few kilometers, 700 meters under the surface and some 30-40 km off the coast of Tel Aviv. According to the researchers, this southeastern region of the Mediterranean has only sparse sea life and therefore the discovery is in fact parallel to discovering an oasis in the middle of an...
  • Natural Climate Shifts Drove Coral Reefs to a Total Ecosystem Collapse Lasting 2,500 Years

    Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science. The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings in the El Nio-Southern Oscillation (ENSO). "As humans continue to pump greenhouse gases into the atmosphere, the climate is once again on the threshold of a new regime, with dire consequences for reef ecosystems unless we get control of climate change," said coauthor Richard Aronson,...

There are several places at the eastern end of that country where carbon dioxide is continuously bubbling up through healthy looking coral reef, with fish swimming around and all that that implies.Coral Reef at Dobu Island with carbon dioxide bubbling through it (photo: Bob Halstead)What that implies is that ocean acidification is no threat at all.

The main cause of global warming, carbon dioxide is a heat-trapping gas that is released through using fossil...
