UN Climate Report on Oceans, Frozen Regions Warns ‘Unprecedented Transitions in All Aspects of Society’ Needed to Sustain Life on Earth

Describing scientists’ latest warnings as “chilling and compelling,” environmentalists called for “enacting radical policies” that protect marine ecosystems and fully phase out fossil fuels.

A landmark United Nations climate report published Wednesday details the observed and anticipated future impacts of planet-heating emissions from human activity on the world’s oceans and frozen zones—and warns of the emerging consequences for humanity, marine ecosystems, and the global environment.

The Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) is a product of the Intergovernmental Panel on Climate Change (IPCC), a U.N. body that assesses the latest science related to the human-caused climate crisis. It follows recent IPCC reports on the consequences of 1.5°C of global warming above pre-industrial levels and the necessity of reforming land use practices worldwide. Continue reading

‘Single Most Important Stat on the Planet’: Alarm as Atmospheric CO2 Soars to ‘Legit Scary’ Record High

“We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases.”

In another alarming signal that the international community is failing to take the kind of ambitious action necessary to avert global climate catastrophe, NOAA released new data Tuesday showing that atmospheric carbon dioxide levels—which environmentalist Bill McKibben described as the “single most important stat on the planet”—reached a “record high” in the month of May.

“The measurement is the highest seasonal peak recorded in 61 years of observations on top of Hawaii’s largest volcano and the seventh consecutive year of steep global increases in concentrations of carbon dioxide (CO2),” NOAA said in a statement on Tuesday. “The 2019 peak value was 3.5 PPM higher than the 411.2 PPM peak in May 2018 and marks the second-highest annual jump on record.” Continue reading

‘Blatant Attempt to Politicize the Science’: Trump Reportedly Moving to End Long-Term Studies of Climate Crisis

“The Trump gang is attacking the scientific process itself in an attempt to prop up fossil fuel industries, delay inevitable action, and run the carbon bubble as long as it will last.”

In what environmental experts warned could be President Donald Trump’s most dangerous assault on science yet, the White House is reportedly moving to end long-term assessments of the impacts of the climate crisis while pushing a polluter-friendly agenda that is making the planetary emergency worse.

As the New York Times reported late Monday, “the White House-appointed director of the United States Geological Survey, James Reilly, a former astronaut and petroleum geologist, has ordered that scientific assessments produced by that office use only computer-generated climate models that project the impact of climate change through 2040, rather than through the end of the century, as had been done previously.

Thawing Permafrost Emitting Higher Levels of Potent Greenhouse Gas Than Previously Thought: Study

Nitrous oxide is nearly 300 times more potent than carbon dioxide

As the Arctic enters an “unprecedented” state of warming, a new study shows that emissions of a potent greenhouse gas from thawing permafrost in the planet’s northernmost region may be 12 times higher than previously thought.

That’s according to a study published this month in the journal Atmospheric Chemistry and Physics. The paper’s findings add even more weight to scientists’ urgent warnings about the mounting threats of permafrost thaw. Continue reading

‘A World Without Clouds. Think About That a Minute’: New Study Details Possibility of Devastating Climate Feedback Loop

“We face a stark choice [between] radical, disruptive changes to our physical world or radical, disruptive changes to our political and economic systems to avoid those outcomes.”

As people across the globe mobilize to demand bold action to combat the climate crisis and scientific findings about looming “environmental breakdown” pile up, a startling new study published Monday in the journal Nature Geoscience warns that human-caused global warming could cause stratocumulus clouds to totally disappear in as little as a century, triggering up to 8°C (14°F) of additional warming.

Stratocumulus clouds cover about two-thirds of the Earth and help keep it cool by reflecting solar radiation back to space. Recent research has suggested that planetary warming correlates with greater cloud loss, stoking fears about a feedback loop that could spell disaster. Continue reading

Warnings of ‘Destructive and Irreversible Impacts’ as Greenhouse Gases Hit Highest Levels in 3-5 Million Years

“The science is clear,” says the head of the World Meteorological Organization. “The window of opportunity for action is almost closed.”

As communities most impacted by the climate crisis ramp up demands for urgent global action, atmospheric concentrations of the top three greenhouse gases driving global warming have hit record high levels, according to the World Meteorological Organization (WMO) out Thursday.”

Last year, as the latest WMO Greenhouse Gas Bulletin (pdf) details, average concentrations of carbon dioxide, methane, and nitrous oxide all rose—with CO2 hitting 405.5 parts per million (ppm), its highest level in a few million years.

The report also noted that there was a “resurgence of a potent greenhouse gas and ozone-depleting substance”—called trichlorofluoromethane, or CFC-11—likely tied to “increased emissions associated with production of CFC-11 in eastern Asia.” Continue reading
