CNN —Extraordinary global heat continues its streak. It marks 11 consecutive months of unprecedented global temperatures. With that new data point, some scientists warn there is a strong chance 2024 could beat 2023 as the warmest year on record. Global ocean heat in April was also record-breaking for the 13th consecutive month. And while heat records are still being set month after month, the margins at which they are being broken are smaller than they were in 2023.

That threshold describes a long-term average rather than a single-year anomaly. But because it describes a multidecade average, the measure will always be backward-looking, with the precise moment the world crossed the 1.5 mark clear only in retrospect. This year a handful of prominent scientists have suggested that when we do look back to mark that time, we may well circle 2023. Not that long ago, it would have been pretty contentious to suggest that the world’s most ambitious climate goal was already lost. Perhaps 2024 is the year we may finally be ready to retire it publicly, too.

The National Climate Assessment, which comes out every four to five years, was released Tuesday with details that bring climate change's impacts down to a local level. Compared to earlier national assessments, this year’s uses far stronger language and “unequivocally” blames the burning of coal, oil and gas for climate change. In the Midwest, both extreme drought and flooding threaten crops and animal production, which can affect the global food supply. “Climate change is finally moving from an abstract future issue to a present, concrete, relevant issue. Five years ago, when the last assessment was issued, fewer people were experiencing climate change firsthand.

This summer of extremes has been a summer of mystery, debate and even some confusion for climate scientists, who’ve been watching the news with the rest of us and asking, What, exactly, is going on? Is it just baseline global warming, trending upward, that explains the extreme temperatures on land and over sea? The arrival of a planet-warming El Niño in the Pacific? And when considering off-the-charts sea-surface temperatures, what role is being played by recent regulations designed to significantly reduce the sulfur emissions of ships, since less pollution in the air means more heat making its way to the water below? And almost certainly, the sulfur effect has been larger locally, along particular shipping routes in the world’s oceans, where some especially striking anomalies have been observed.

☆ Oceans absorb 90% of the heat from climate change — here's why record ocean temps are so harmful

"Over 90 percent of the excess energy on earth due to climate change is found in warmer oceans, some of it in surface oceans and some at depth." Put simply, the greenhouse gases serve to trap more heat, some of which is absorbed by the ocean," Kirtman told CNBC. In addition to the daily record on July 31, the monthly sea surface temperature for July was the hottest July on record, "by far," Copernicus said. CopernicusThese record sea surface temperatures arise from multiple factors, including the El Niño weather pattern, which is currently in effect. "These climate variations occur when sea surface temperature patterns of warming and cooling self-reinforce by changing patterns of winds and precipitation that deepen the sea surface temperature changes."

☆ July hit a crucial warming threshold that scientists have warned the world should stay under
▼ + stars: | 2023-08-08 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +4 min

Copernicus scientists say it’s the first summer month that has surpassed 1.5 degrees, offering a glimpse of future summers. Scientists are particularly concerned that global temperature will stay above 1.5 degrees for the long term. Before that, the other months that have been 1.5 degrees warmer than pre-industrial times have occurred during winter or early spring. “The year-to-date average is still below 1.5 degrees Celsius, and we find it unlikely that the rest of 2023 will be warm enough to bring the whole year average above 1.5,” he said. Copernicus scientists noted that as El Niño continues to develop, the world may witness more of these unprecedented temperature breaches.

The planet’s average sea surface temperature spiked to a record high in April and the ocean has remained exceptionally warm ever since. Some have suggested that international rules aimed at reducing air pollution from maritime shipping could have inadvertently increased ocean warming. Warmer ocean temperatures also provide more fodder for tropical cyclones and atmospheric river storms.

It works like this: As the world burns fossil fuels and pumps out planet-heating pollution, global temperatures are steadily warming. David J. Phillip/APWhile the record temperatures may have been expected, the magnitude by which some have been broken has surprised some scientists. Historically, global heat records tend to topple in El Niño years, and the current record-holder, 2016, coincided with a strong El Niño. The world gets hung up on blockbuster records but “these heat records are not exciting numbers,” she told CNN. CFOTO/Future Publishing/Getty ImagesUnheeded warningsFor climate scientists, this is the “I told you so” moment they never wanted.

CNN —The planet’s temperature soared again on Thursday to levels not seen in the modern record-keeping era, marking the fourth straight day of record temperatures. On Monday, the average global temperature reached 17.01 degrees Celsius (62.62 degrees Fahrenheit), the highest in the NCEP’s data, which goes back to 1979. On Tuesday it climbed to 17.18 degrees Celsius, where it remained on Wednesday. Before this week, the record in NCEP’s data was 16.92 degrees Celsius and was set in August 2016. Temperature records aren’t just numbers, “but for many people and ecosystems it’s a loss of life and livelihood.”

☆ Heat Records Fall Around the Globe as Earth Warms, Fast

On Tuesday, global average temperatures rose to a new high of 62.9 degrees Fahrenheit. But, he added, there may be other factors layered on top of human-caused warming that have helped drive temperatures up so dramatically in recent months. For instance, a cyclical phenomenon in the Pacific Ocean known as the El Niño-Southern Oscillation causes year-to-year fluctuations by shifting heat in and out of deeper ocean layers. Global surface temperatures tend to be somewhat cooler during La Niña years and somewhat hotter during El Niño years. “A big reason we’re seeing so many records shattered is that we’re transitioning out of an unusually long three-year La Niña, which suppressed temperatures a bit, and into a strong El Niño,” Dr. Hausfather said.

☆ 63 cruise ships owned by Carnival Corporation released more toxic sulfur gasses than all the cars in Europe, study says
▼ + stars: | 2023-07-05 | by ( Hannah Towey | Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +6 min

63 cruise ships owned by Carnival Corp. emitted more sulfur oxides than all the cars in Europe in 2022. The cruise industry is investing in alternative energy sources such as LNG fuel and shore power. Though the IMO rule slashes the sulfur emissions of individual ships, it has done nothing to limit the increasing number of cruise ships in recent years. Compared to 2019, cruise ships are also spending more time at European ports and consuming more fuel, per the report. As a result, cruise ships overall emitted 9% more sulfur oxides in 2022 than in 2017, according to Transport & Environment.

July 4 - Monday, July 3, was the hottest day ever recorded globally, according to data from the U.S. National Centers for Environmental Prediction. The average global temperature reached 17.01 degrees Celsius (62.62 Fahrenheit), surpassing the August 2016 record of 16.92C (62.46F) as heatwaves sizzled around the world. Ukraine's Vernadsky Research Base in the white continent's Argentine Islands recently broke its July temperature record with 8.7C (47.6F). "This is not a milestone we should be celebrating," said climate scientist Friederike Otto of the Grantham Institute for Climate Change and the Environment at Britain's Imperial College London. Scientists said climate change, combined with an emerging El Nino pattern, were to blame.

☆ Fact Check-Eight cooler years cannot be extrapolated to draw conclusions on long-term global warming
▼ + stars: | 2023-02-03 | by ( Reuters Fact Check | ) www.reuters.com time to read: +6 min

SHORT TERM FLUCTUATIONSGlobal surface temperatures are heavily influenced by annual Pacific Ocean patterns known as El Nino and La Nina, and collectively as ENSO (El Niño–Southern Oscillation). A large El Nino event followed by a La Nina can “lead to a temporary ‘pause’ in global temperatures over timescales of a decade or so”, Hausfather said. This is “what we are now seeing after the 2015/2016 super El Nino event”. Whenever there is a trend with variability like global temperatures, “you can isolate cherry-picked intervals and claim that something has paused or accelerated, but this is not appropriate”, Colose said. Temperature data for the past eight years do not reflect long-term trends, experts say, and longer-term data clearly show a continuing rise in overall global temperatures.

☆ New York prepares for possible flooding from snowmelt while the West girds for heavy rain and snow

Kathy Hochul on Wednesday directed state agencies to prepare to respond to flooding caused by the snowmelt. And the Buffalo Airport — where nearly 52 inches of snow fell during the storm, according to the weather service — reopened Wednesday. Moderate to heavy snow could also fall across northern Nevada by Friday night, the agency said. On New Year’s Eve, heavy rain will fall in the Southeast up to the Ohio Valley during the day and the mid-Atlantic into the Northeast during the evening, while the West will face a flood risk and continued heavy mountain snow. On New Year's Day, lingering rain showers are expected in New England, above-average temperatures are set for the South and rain and snow are expected in the Southwest.
