Greenhouse Gases Reach Unprecedented Level
A bleak new federal report found that carbon dioxide in the atmosphere rose to levels the world has not seen in at least 800,000 years, highlighting the irreversible and mounting deleterious effects of human activity on the planet, as ABC News reported.
Global carbon dioxide concentrations reached a record of 407.4 parts per million during 2018, the study found. That is 2.4 ppm greater than 2017 and "the highest in the modern instrumental record and in ice core records dating back 800,000 years," the report said, according to CNN.
It wasn't just the amount of carbon dioxide that set record levels. Other greenhouse gases like methane and nitrous oxide also continued a rapid rise into the atmosphere. Together, the global warming power of greenhouse gases was 43 percent stronger than in 1990, according to the State of the Climate report released Monday by the American Meteorological Society, a division of the National Oceanic and Atmospheric Administration's (NOAA) National Centers for Environmental Information.
Greenhouse gases are not the only thing rising. Global sea levels also reached their highest levels on record for the seventh consecutive year, as ABC News reported. The report says that ocean levels are rising about an inch per decade, but that number may need to be revised if ice melt at the poles accelerates.
For global temperatures, 2018 ranked fourth, behind 2016, 2015 and 2017 for the warmest on record. That top four finish for 2018 is despite a La Niña system over the Pacific that cooled ocean waters for part of the year.
So far, 2019 is on track to be the warmest year in recorded history, according to NOAA.
Global sea temperatures also set a record level in 2018. "This record heat reflects the continuing accumulation of thermal energy in the top 2,300 feet (700 meters) of the ocean," according to NOAA. "Oceans absorb more than 90 percent of Earth's excess heat from global warming."
"Every year since the start of the 21st Century has been warmer than the 1981-2010 average," the report said, as CNN reported. "In 2018, the dominant greenhouse gases released into Earth's atmosphere — carbon dioxide, methane, and nitrous oxide — continued to increase and reach new record highs."
The 29th annual release of the State of the Climate report was led by NOAA National Centers for Environmental Information and relies on contributions from more than 470 scientists from nearly 60 countries around the world. It incorporates tens of thousands of measurements from multiple independent datasets and provides a detailed update on global climate indicators and notable weather events, according to NOAA.
"This is yet another in a series of expert, science-based reports that continue to sound the alarm about the climate crisis," said Marshall Shepherd, a professor of geography and atmospheric sciences at the University of Georgia and former president of the American Meteorological Society, to CNN. "[The] DNA of climate change is clearly seen now in our weather, agriculture productivity, water supply challenges, public health, and even national security concern."
"The findings from their State of the Climate report rise above some blog or opinion on social media," Shepherd added. "Through the process of science, they are sounding an alarm about the 'here-and-now' climate crises."

Climate change, habitat loss and pollution are overwhelming our planet. Thankfully, these enormous threats are being met by a bold new wave of environmental activism.
Trump Makes Strange Claim About Water Efficient Toilets: 'People Are Flushing Toilets 10 Times, 15 Times'
President Donald Trump mocked water-efficiency standards in new constructions last week. Trump said, "People are flushing toilets 10 times, 15 times, as opposed to once. They end up using more water. So, EPA is looking at that very strongly, at my suggestion." Trump asked the Environmental Protection Agency (EPA) for a federal review of those standards since, he claimed with no evidence, that they are making bathrooms unusable and wasting water, as NBC News reported.

Former Monsanto Chairman and CEO Hugh Grant will have to testify in person at a St. Louis-area trial set for January in litigation brought by a cancer-stricken woman who claims her disease was caused by exposure to the company's Roundup herbicide and that Monsanto covered up the risks instead of warning consumers.
A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.
"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."
The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.
My god, White Island volcano in New Zealand erupted today for first time since 2001. My family and I had gotten off it 20 minutes before, were waiting at our boat about to leave when we saw it. Boat ride home tending to people our boat rescued was indescribable. #whiteisland pic.twitter.com/QJwWi12Tvt— Michael Schade (@sch) December 9, 2019

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.
The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.
Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.
"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."
Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.
Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.
"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.
"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."
The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.
Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
