Temperature anomaly of nearly 3°c is bonkers.… Four warmest years on record: 2016, 2015, 2017 & 2018. 2018 to be nominally the 4th warmest year on record globally, at 0.91±0.1°C above the long-term pre-industrial average. This means that the last four years have been the warmest on record.
And today’s dose bad climate news ... Forecast patterns suggest enhanced warming is likely over much of the globe, especially over land and at high northern latitudes, particularly the Arctic region. The heat goes on in south Australia. Many locations recording highest recorded March temperatures and warmest March nights.… *****UK weather: February temperature jump was incredible, says climate expert. This week’s record winter heat in the UK was so far above normal trends that scientists have been forced to reconsider their statistical models, with one expert calling the temperature jump “incredible”.
UK temperature records have tumbled in the past 10 days. It’s at least a one-in 200-year event...the probability of this week’s temperatures was close to zero #FebruaryHeatwave @PeterGWeather.

The Earth is facing a ‘clear and unequivocal’ climate emergency, say 11,000 scientists. New study shows how greenhouse gas emissions are still rising with increasingly damaging effects. All summarised by these graphs...… ‘High likelihood of human civilisation coming to end’ by 2050, report finds. Could it be orbital cycles? Are we just getting warmer after the last ice age? No: warming from the last ice age peaked 1000s of yrs ago, and the next event on our geologic calendar was another ice age: was, until the industrial revolution, that is. Read.
Scientists puzzled by slowing of Atlantic conveyor belt, warn of abrupt climate change. A Delaware-Sized Chunk Of Ice May Soon Detach From Antarctic Shelf. Mapping Methane in a Bubbling Arctic Lake. By Kate Ramsayer / FAIRBANKS, ALASKA / At first glance, it looks like a typical, picture-perfect lake.
But scan the reeds along the shore of this pool on the outskirts of Fairbanks, or glance at the spruce trees lining the banks, and you notice something different is going on. Methane bubbles pop on the surface of a lake near Fairbanks, Alaska. Thawing permafrost in the lakebed soils releases old carbon, which microbes eat up and turn into methane. Carbon emissions 'postpone ice age'. Image copyright Ittiz The next ice age may have been delayed by over 50,000 years because of the greenhouse gases put in the atmosphere by humans, scientists in Germany say.
167 Tiny Maps Tell the Major Story of Climate Change. Climate change just got another telling visual courtesy of the famed temperature spiral creator.
But rather than a graph, it’s a series of 167 maps. Alone, they each tell the story of whether a year was mostly hot or mostly cold or mostly average. Climate Change could jam thermohaline circulation - Nicola Jones: Yale Environment 360. 06 Sep 2016: Analysis by nicola jones Mariusz Kluzniak/Flickr Melting ice flows into the northern Atlantic Ocean in eastern Greenland.
Susan Lozier is having a busy year. From May to September, her oceanographic team is making five research cruises across the North Atlantic, hauling up dozens of moored instruments that track currents far beneath the surface. QBO "Old Faithful" of Earth's stratosphere failed to erupt. What's happening? @NASAGoddard scientists investigate. Climate Running AMOC. Thermohaline circulation (n.): deep ocean current driven by variations in salinity and temperature.
QBO Unprecedented disruption to atmosphere's pacemaker foretells wet winter for Europe. High in the stratosphere, winds whip around Earth's equator, switching from westerlies to easterlies and back again roughly every 28 months.
Although the length of the cycle varies from year to year, the quasi-biennial oscillation (QBO), as it is known, is as dependable as they come: It had not skipped a beat since scientists first reported its existence in 1960. Until now. Global warning: ocean warming. A new IUCN report, entitled Explaining ocean warming: causes, scale, effects and consequences, sets out the most recent and comprehensive review to date on this topic and shows a complex story of change in the ocean.
This change is underway, often already locked in for many decades to come, and has already begun to impact people’s lives. This is no longer a single story of ocean warming challenges to coral reefs, but a rapidly growing list of alarming changes across species at ecosystem scales, and across geographies spanning the entire world.
