Hurricanes Getting Stronger, Faster: New Study

Hurricanes in the Atlantic are growing stronger faster than ever before, according to a new study. Indeed, a hurricane is now twice as likely to grow from a weak storm into a major Category 3  (or stronger) hurricane in just 24 hours. The study, just published in Scientific Report, adds to the growing body of evidence that fast-growing major hurricanes are becoming more likely. Andra Garner, an assistant professor at Rowan University who wrote the study, says that from 2001 to 2020 tropical cyclones in the Atlantic had an 8 percent chance of strengthening from a Category 1 storm into…

101 Degrees in Florida Bay; Atlantic Near “Tipping Point”

Sea water temperatures hit a scorching 101.1 degrees Fahrenheit earlier this week for the first time in history off south Florida, threatening coral reefs and all marine life. Meanwhile, a new study says that the major currents in the Atlantic Ocean, including the Gulf Stream, could weaken and hit an irreversible “tipping point” as soon as two years from now, affecting sea levels and weather patterns in the U.S., Canada and Europe. In the Florida Keys, unprecedented ocean temperatures have caused a mass bleaching of coral reefs. Marine scientists say many reefs are now completely bleached, or already dead. They…

Ocean Heatwaves Will Get Worse: NOAA

Half the oceans of the world may register heatwaves by September, according to a new NOAA forecast. Here’s the NOAA report: As scientists around the world sound the alarm about record sea surface temperatures, a new experimental NOAA forecast system predicts that half of the global oceans may experience marine heatwave conditions by the end of summer. The surface temperatures of about 40% of the global oceans are already high enough to meet the criteria for a marine heatwave — a period of persistent anomalously warm ocean temperatures — which can have significant impacts on marine life as well as…

Ocean Temps Warmest Ever in May: NOAA

Ocean temperatures last month were the warmest ever recorded, according to the National Oceanic and Atmospheric Administration. The records date back to 1850. Meanwhile, North and South America recorded the hottest temperatures ever in May, while May was the third-warmest on record for the entire world. Temperatures in North America were driven by wildfires in Canada (pictured). Here’s the NOAA report: It was another warm month for the globe, with May 2023 ranking as the world’s third-warmest May on record. Earth’s ocean surface temperatures also set a record high for the second month in a row, according to scientists from…

Arctic Summer Ice: Going, Going, Gone

CNN— The Arctic could be free of sea ice roughly a decade earlier than projected, scientists warn – another clear sign the climate crisis is happening faster than expected as the world continues to pump out planet-heating pollution. A new study published Tuesday in the journal Nature Communications found Arctic sea ice could disappear completely during the month of September as early as the 2030s. Even if the world makes significant cuts to planet-heating pollution today, the Arctic could still see summers free of sea ice by the 2050s, scientists reported. The researchers analyzed changes from 1979 to 2019, comparing different…

New Study: Sea Levels To Rise 10 Inches

Melting ice in Greenland could result in a 10-inch rise in sea water around the world, more than twice the increase previously believed, according to a new study. The problem is what researchers call “zombie ice,” or ice that is no longer getting replenished from glaciers that are receiving less snow because of global warming. It is basically doomed ice that eventually will melt and raise sea levels. A new study just published in Nature Climate Change looked at Greenland’s melting ice sheet and said the sea levels would raise by at least ten inches even if we stopped burning…

Arctic Warming Much Faster Than Expected

The Arctic is warming much faster than scientists had predicted, according to a new study in Finland. Previously, they thought it was heating up twice as fast as the rest of the world. But now, a long-term study by the Finnish Meteorological Institute says the Arctic actually is heating up four times as fast. “Temperatures are rising faster in the Arctic region than globally,” said Mika Rantanen, the author of the study. In fact, some areas are heating at a much faster rate. Some parts of the Barents Sea above Norway and Russia are heating up seven times faster, the…

NOAA: June Was 6th Warmest Month Ever

Here’s the latest monthly report from NOAA, with some disturbing news: June’s average global temperature continued 2022’s remarkably warm trend, as both the month and the year so far ranked sixth warmest on record. In addition, global sea ice reached near-record lows last month, with Antarctica seeing its lowest June ice coverage on record, according to scientists from NOAA’s National Centers for Environmental Information (NCEI). (An iceberg on the Antarctic Peninsula is pictured above.) Here’s a closer look into NOAA’s latest monthly global climate report: Climate by the numbers June 2022 The average global surface (land and ocean) temperature in…

Climate Change Increasing Too Fast: UN Report

Climate change is happening so fast that we may not be able to turn it around, according to a new report by a global group of scientists working with the United Nations. Rising sea levels are a particular concern, along with increasingly intense storms, particularly on the Gulf and East Coasts of the United States. By 2050, sea levels could  be as much as 10 to 12 inches higher than they are today, affecting metropolitan areas, waterfront communities, power plants and oil refineries. The report, issued by the Intergovernmental Panel on Climate Change, involved 270 scientists from 67 countries. It…

Historic Iceberg Breaks Up in South Atlantic

One of the largest icebergs ever measured (roughly the size of Delaware) has broken up near South Georgia Island in the South Atlantic, releasing billions of tons of fresh water into the ocean and potentially affecting life at sea and on shore. The iceberg was known as A68A, and it broke off the Larsen-C Ice Shelf in the Antarctic in July, 2017. At the time, it was more than 100 miles long and 30 miles wide. It also was almost 800 feet thick, with only the top 120 feet showing above the surface. Scientists from the European Space Agency said…
