The east is defending itself against twice the usual number of tropical cyclones.

On Sunday night, America met Michael Mann on 60 Minutes, one of the country’s most watched and influential television news programs for nearly 50 years now.

Many Scientists Now Say Global Warming Could Stop Relatively Quickly After Emissions Go to Zero - Inside Climate News. Parts of the world economy may have been on pause during 2020, dampening greenhouse gas emissions for a while.

But that didn’t slow the overall buildup of atmospheric carbon dioxide, which reached its highest level in millions of years. If anything, research during the year showed global warming is accelerating. The end of the Arctic as we know it. The demise of an entire ocean is almost too enormous to grasp, but as the expedition sails deeper into the Arctic, the colossal processes of breakdown are increasingly evident.

And that’s got scientists worried about what it means for the rest of the world. The thermometer hit a likely record of 38 degrees Celsius (100.4 degrees Fahrenheit) in the Russian Arctic town of Verkhoyansk on Saturday, a temperature that would be a fever for a person — but this is Siberia, known for being frozen. The World Meteorological Organization said Tuesday that it’s looking to verify the temperature reading, which would be unprecedented for the region north of the Arctic Circle. “The Arctic is figuratively and literally on fire — it’s warming much faster than we thought it would in response to rising levels of carbon dioxide and other greenhouse gases in the atmosphere, and this warming is leading to a rapid meltdown and increase in wildfires,” University of Michigan environmental school dean Jonathan Overpeck, a climate scientist, said in an email.

Methane is a naturally occurring Greenhouse Gas (GHG), but one whose abundance has been increased substantially above its pre-industrial value of some 720 ppb by human activities, primarily because of agricultural emissions (e.g., rice production, ruminants) and fossil fuel production and use. A clear annual cycle is largely due to seasonal wetland emissions. Sans titre. Dire Warning The global ecosystem is in far greater danger than scientists previously thought, according to a new study — and that’s really saying something. The research predicts that without dire action to reverse global climate change, entire ocean ecosystems could suddenly collapse this decade, The Guardian reports. It’s a dire warning: as various organisms face temperatures higher than anything they have before, the study predicts sudden, massive die-offs. Sans titre. 1.Urban, M. C.

Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said. Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts said the projections had the potential to be “incredibly alarming”, though they stressed further research would be needed to validate the new numbers.

Modelling results from more than 20 institutions are being compiled for the sixth assessment by the United Nations Intergovernmental Panel on Climate Change, which is due to be released next year. Compared with the last assessment in 2014, 25% of them show a sharp upward shift from 3C to 5C in climate sensitivity – the amount of warming projected from a doubling of atmospheric carbon dioxide from the preindustrial level of 280 parts per million.

Sans titre. Tens of millions of people are set to face food shortages on the continent after a plague of locusts embarked on a path of destruction across India and Pakistan. In Pakistan, a national emergency has been declared after an outbreak of locusts’, on a biblical scale, wreaked havoc across farmland in the eastern Punjab, southern Sindh and southwestern Baluchistan provinces. In western and central India up to 125,000 acres of crops have been ruined during the worst outbreak the country has faced in decades. Clefs200857memoC. Climate Change: Our Future Depends on What Happens to the Ocean. The blob went unnoticed at first. In the summer of 2013, a high-pressure ridge settled over a Texas-size area in the northern Pacific, pushing the sky down over the ocean like an invisible lid. The winds died down, and the water became weirdly calm.

Without waves and wind to break up the surface and dissipate heat, warmth from the sun accumulated in the water, eventually raising the temperature by 5 degrees Fahrenheit — a huge spike for the ocean. When scientists noticed this temperature anomaly in the satellite data, they had never seen anything like it. Everyone knew about heat waves on land, but in the ocean? Sans titre. Sans titre. Every year, a final warming event occurs in the stratosphere, as we head into spring, and the Sun starts warming up the polar regions. Sometimes a final warming event can occur earlier, as a Sudden Stratospheric Event, from which the disrupted polar vortex never recovers during the cold season.

Sans titre. Tropical forests are taking up less carbon dioxide from the air, reducing their ability to act as “carbon sinks” and bringing closer the prospect of accelerating climate breakdown. The Amazon could turn into a source of carbon in the atmosphere, instead of one of the biggest absorbers of the gas, as soon as the next decade, owing to the damage caused by loggers and farming interests and the impacts of the climate crisis, new research has found.
