New Research Finds Large Buildup Of Heat In The Oceans

The world’s oceans have been soaking up far more excess heat in recent decades than scientists realized, suggesting that Earth could be set to warm even faster than predicted in the years ahead, according to new research published Wednesday.

Over the past quarter-century, Earth’s oceans have retained 60 percent more heat each year than scientists previously had thought, said Laure Resplandy, a geoscientist at Princeton University who led the startling study published Wednesday in the journal Nature. The difference represents an enormous amount of additional energy, originating from the sun and trapped by Earth’s atmosphere — the yearly amount representing more than eight times the world’s annual energy consumption.

The higher-than-expected amount of heat in the oceans means more heat is being retained within Earth’s climate system each year, rather than escaping into space. In essence, more heat in the oceans signals that global warming is more advanced than scientists thought.

Wednesday’s study also could have important policy implications. If ocean temperatures are rising more rapidly than previously calculated, that could leave nations even less time to dramatically cut the world’s emissions of carbon dioxide, in the hope of limiting global warming to the ambitious goal of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels by the end of this century.

Global Warming Is Messing with the Jet Stream

Greenhouse gases are increasingly disrupting the jet stream, a powerful river of winds that steers weather systems in the Northern Hemisphere. That’s causing more frequent summer droughts, floods and wildfires, a new study says.

The findings suggest that summers like 2018, when the jet stream drove extreme weather on an unprecedented scale across the Northern Hemisphere, will be 50 percent more frequent by the end of the century if emissions of carbon dioxide and other climate pollutants from industry, agriculture and the burning of fossil fuels continue at a high rate.

The study identifies how the faster warming of the Arctic twists the jet stream into an extreme pattern that leads to persistent heat and drought extremes in some regions, with flooding in other areas.

The researchers said they were surprised by how big a role other pollutants play in the jet stream’s behavior, especially aerosols—microscopic solid or liquid particles from industry, agriculture, volcanoes and plants. Aerosols have a cooling effect that partially counteracts the jet stream changes caused by greenhouse gases.

Roundup of Global Volcanic Activity – New Activity for the week of 24 October – 30 October 2018

Ambae | Vanuatu : At 1832 on 30 October an eruption at Ambae’s Lake Voui generated ash plumes that rose to altitudes of 3-10.7 km (10,000-35,000 ft) a.s.l. and drifted mainly E and SE, based on satellite data, ground-based observations, wind model data, Vanuatu Meteorology and Geo-hazards Department (VMGD), and the Wellington VAAC. According to the VAAC the ash cloud was about 3,400-5,100 square kilometers in area.

Kuchinoerabujima | Ryukyu Islands (Japan) : Based on satellite images and information from JMA, the Tokyo VAAC reported that during 24-28 October ash plumes from Kuchinoerabujima’s Shindake Crater rose to altitudes of 0.9-1.5 km (3,000-5,000 ft) a.s.l. and drifted in multiple directions. JMA scientists noted no changes in the thermal anomalies at the crater during a field observation on 28 October. The Alert Level remained at 3 (on a scale of 1-5).

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind-model data, the Darwin VAAC reported that on 30 October an ash plume from Langila rose to an altitude of 2.7 km (9,000 ft) a.s.l. and drifted SE.
