Sea levels are going to rise by at least 2ft. We can do something about it | Harold R Wanless

To avoid the grimmest outlook posed by warming oceans, we need to extract heat-trapping gases from the atmosphere The climate emergency is bigger than many experts, elected officials, and activists realize. Humanity’s greenhouse gas emissions have overheated the Earth’s atmosphere, unleashing punishing heat waves, hurricanes, and other extreme weather – that much is widely understood. […]

The Rise and Fall of the “Atlantic Multidecadal Oscillation”

Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (AMO) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. These interactions were thought to lead to alternating decades-long intervals of […]

Blue carbon: how three Australian marine sites lock away 2bn tonnes of CO2

Greenhouse gas stored in country’s marine world heritage sites about same as four years of emissions Three of Australia’s world heritage-listed marine sites have more than 2bn tonnes of carbon dioxide locked away in their vast seagrass meadows, coastal mangroves and tidal marshes, according to a new report from a UN agency. Unesco has for […]

Doomsday AMOC “Tipping” Claimed In ‘Nature’ Already Refuted…New Study: AMOC “Shows No Decline”

A recent study appearing in Nature, “Current Atlantic Meridional Overturning Circulation weakest in last millennium“, authored by Caesar et al, hints at a global climate system on the verge of tipping out of control. According to their findings, the weakening of the so-called Atlantic Meridional Overturning Current (AMOC) in the 20th century is “unprecedented”, and […]

Changes in Atlantic currents may have dire climate implications for the next century | Andrew Meijers

Without modifying human behavior we run the risk of violent weather swings and a drastic effect on crops and ocean life The ocean circulation that keeps our relatively northern corner of Europe warm(ish) is often likened to a gigantic conveyor belt bringing warm equatorial water northwards at the surface, balanced by cold southward flow at […]

Climate crisis: world is at its hottest for at least 12,000 years – study

Scientists say temperatures globally at highest level since start of human civilisation The planet is hotter now than it has been for at least 12,000 years, a period spanning the entire development of human civilisation, according to research. Analysis of ocean surface temperatures shows human-driven climate change has put the world in “uncharted territory”, the […]

Scientists Determine CO2 Levels Must TRIPLE To Yield A Tiny 0.5 W/m² Forcing At The Ocean Surface

Oceans cover 71% of the Earth’s surface. An analysis of CO2’s radiative effect on ocean temperatures finds CO2 forcing is negligible even after reaching a concentration of 1,071 ppm. In the tropical oceans, 500 to 1,000 W/m² of solar radiation uniformly heats the first 2 meters of the ocean surface by 2 Kelvin in a […]

Climate crisis: record ocean heat in 2020 supercharged extreme weather

Scientists say temperatures likely to be increasing faster than at any time in past 2,000 years Analysis: why are ocean warming records being broken year after year? The world’s oceans reached their hottest level in recorded history in 2020, supercharging the extreme weather impacts of the climate emergency, scientists have reported. More than 90% of […]

Number Of Global Wild Fires Trending Down Since 2003. Northern Ocean Heat Content Drops Since 2010

Dr. Sebastian Lüning recently started his own weekly YouTube videos on climate news in German: Klimaschau. Global wild fires on the decline  In his latest video the veteran geologist looks at wild fires worldwide and the CO2 they emit. He reports that both have been decreasing. Citing the results of the European Copernicus satellite atmosphere […]

Alarmism Dies In The Maldives: 97% Of 186 Island Coasts Have Grown (59%) Or Not Changed (38%) Since 2005

Despite sea level rise, a 2019 global analysis (Duvat, 2019) found 89% of 709 island coasts have been either stable or growing in size in recent decades. A new Maldives-only study (Duvat, 2020) finds rapid (>3 to >50%) coastal growth in 110 of 186 Maldives islands from 2005 to 2016. Just 5 islands – 2.7% […]
