Small increase in temperature of intruding water could lead to very big increase in loss of ice, scientists say
A long-term sea level dataset shows ocean surface heights continuing to rise at faster and faster rates over decades of observations. Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, a relatively large jump due mostly to a warming climate and the development of a strong El Niño. The total rise is equivalent to draining a quarter of Lake Superior into the ocean over the course of a year.
In March and April 2023, some Earth scientists began to point out that average sea surface temperatures had surpassed the highest levels seen in a key data record maintained by NOAA. Months later, they remain at record levels, with global sea surface temperatures 0.99°C (1.78°F) above average in July. That was the fourth consecutive month they were at record levels.

Unprecedented levels of damage from storms this year is upending US towns and the insurance industry
(09/08) - MICHELLE CHAPMANWaves of severe thunderstorms in the U.S. during the first half of this year led to $34 billion in insured losses, an unprecedented level of financial damage in such a short time as climate change contributes to the frequency and severity of violent meteorological events. The reinsurer Swiss Re Group said Wednesday that damages from convective storms in the U.S., which can come with hail, lightning, heavy rain and high winds, accounted for nearly 70% of the $50 billion in global catastrophic damages so far this year. The storms in the U.S. were so severe, there were 10 that resulted in damages of $1 billion or more, almost double the average over the last decade.
Global coal consumption climbed to a new all-time high in 2022 and will stay near that record level this year as strong growth in Asia for both power generation and industrial applications outpaces declines in the United States and Europe, according to the IEA’s latest market update.
With the continent holding enough ice to raise sea levels by many metres if it was to melt, polar scientists are scrambling for answers
An increase in the pace at which sea levels are rising threatens “a mass exodus of entire populations on a biblical scale”, the UN secretary general has warned. The climate crisis is causing sea levels to rise faster than for 3,000 years, bringing a “torrent of trouble” to almost a billion people, from London to Los Angeles and Bangkok to Buenos Aires, António Guterres said on Tuesday. Some nations could cease to exist, drowned under the waves, he said.
A community of Indigenous peoples worried that mercury used by gold miners was contaminating the fish they eat. So they created a DIY team to find out more.
