20 July 2018 (Zero Hour) – Zero Hour is not mobilizing just for the sake of mobilizing. We the youth are demanding an end to business as usual on climate change, so we have created science-backed demands for both our leaders, and the general public to take action on. On July 19th youth are taking over Capitol Hill to deliver our demands to our elected officials. We are giving them the exact asks that we are marching for—so they have no excuse not to take action.

We have written a platform, a letter to elected officials and a set of guiding principles to make it clear what we’re standing for and why. Click here to read our platform and principles.

We will prepare for our mobilization by having art builds around the DC area to celebrate our movement and earth through art. In any movement, it is important to have community building, because community is the best antidote to hopelessness. Through these art builds we are building our community and beautiful banners and signs for The Youth Climate March.

In Washington D.C., youth will march on the National Mall to advocate for their own rights to a safe and livable future. We will rally and highlight the voices and stories of youth on the frontlines of the climate crisis. Then, we will flood the streets as a demonstration of youth power and show how #ThisIsZeroHour to act on climate change.

(The Guardian) – At least 11 wildfires are raging inside the Arctic Circle as the hot, dry summer turns an abnormally wide area of Europe into a tinderbox.

The worst affected country, Sweden, has called for emergency assistance from its partners in the European Union to help fight the blazes, which have broken out across a wide range of its territory and prompted the evacuations of four communities.

Tens of thousands of people have been warned to remain inside and close windows and vents to avoid smoke inhalation. Rail services have been disrupted.

The Copernicus Earth observation programme, which gives daily updates of fires in Europe, shows more than 60 fires burning across Sweden, with sites also ablaze in Norway, Finland, and Russia, including in the Arctic Circle.

Norway has sent six fire-fighting helicopters in response to its neighbour’s request for assistance. Italy is sending two Canadair CL-415s – which can dump 6,000 litres of water on each run – to Örebro in central southern Sweden.

In western Sweden, fire-fighting operations were temporarily halted near an artillery training range near Älvdalen forest due to concerns that unexploded ordnance might be detonated by the extreme heat.

Residents in Uppsala said they could see the plumes of smoke and have been banned from barbecuing in national parks, after 18 consecutive days without rain.

“This is definitely the worst year in recent times for forest fires. Whilst we get them every year, 2018 is shaping up to be excessive,” said Mike Peacock, a university researcher and local resident. […]

“What we’re seeing with this global heatwave is that these areas of fire susceptibility are now broadening, with the moors in north-west England and now these Swedish fires a consequence of that,” said Vincent Gauci, professor of global change ecology at the Open University. [more]

Wildfires rage in Arctic Circle as Sweden calls for help

Rio de Janeiro (The Guardian) – Remarkable footage has been released of an uncontacted indigenous man who has lived alone in an Amazon forest for at least 22 years.

Semi-naked and swinging an axe vigorously as he fells a tree, the man, believed to be in his 50s, has never been filmed so clearly before and appears to be in excellent health.

“He is very well, hunting, maintaining some plantations of papaya, corn,” said Altair Algayer, a regional coordinator for the Brazilian government indigenous agency FUNAI in the Amazon state of Rondônia, who was with the team who filmed the footage from a distance. “He has good health and a good physical shape doing all those exercises.”

Known as the “indigenous man in the hole”, he is believed to be the only survivor from an isolated tribe. He hunts forest pigs, birds and monkeys with a bow and arrow and traps prey in hidden holes filled with sharpened staves of wood. He and his group were known for digging holes and his hammock is strung over one in his house.

Loggers, farmers and land grabbers murdered and expelled indigenous populations in the area in the 1970s and 1980s, and the man is believed to be the only survivor of a group of six killed during an attack by farmers in 1995. He was first located in 1996 and has been monitored by FUNAI ever since. A glimpse of his face filmed in 1998 was shown in the Brazilian documentary, Corumbiara, They Shoot Indians, Don't They? […]

The Brazilian government agency FUNAI has released footage of an isolated indigenous man they have been monitoring for 22 years. Known as the ‘man of the hole’, he has become famous in recent decades for his persistence in avoiding contact and continuing his life in the forest.  He is believed to be the only survivor of an isolated community that lived in this indigenous territory in the Amazon state of Rondônia. The community was subject of the 2009 documentary, Corumbiara.

Fiona Watson, the research and advocacy director of Survival International, a non-profit group that works to protect indigenous peoples, described the footage as “extraordinary” given that the 8,070 hectares of protected forest the man lives in is completely surrounded by ranches and farms.

“FUNAI has a duty to show that he is well and alive,” she said. “The crucial thing is FUNAI has managed to keep his territory.”

Survivors of other indigenous groups in the region have described how farmers shot at their backs when they fled raids on their villages, Watson said. In 2005, she joined a FUNAI mission to the reserve and saw the holes the man had dug around his territory, his house and his plantations, though she did not see him.

“The fact he is still alive gives you hope,” she said. “He is the ultimate symbol, if you like.” [more]

(Weather Underground) – Temperatures soared into the nineties Fahrenheit north of the Arctic Circle on Tuesday and Wednesday, as 2018’s parade of exceptional heat continued marching across the Northern Hemisphere. This week has been northern Scandinavia’s turn under the sizzling klieg lights, including Lapland (Sápmi), the region of northern Scandinavia famed for its reindeer and often associated with Christmas. In contrast to that wintry reputation, Sweden is now grappling with an onslaught of wildfires unprecedented in modern times, as reported by weather.com.

Here’s a sampling of the preliminary all-time highs set in Scandinavia on Tuesday.

Finland

  • Kilpisjärvi:  28.3°C (82.5°F)
  • Kittila Pokka: 30.2°C (86.4°F)
  • Salla: 31.5 (88.7°F)
  • Sodankylä: 31.8°C (89.2°F)
  • Rovaniemi (capital of the Finnish province of Lapland):  32.2°C (90.0°F)

Norway

  • Sihcajavri: 29.2°C (84.6°F)
  • Namsskogan: 32.6°C (90.7°F)
  • Mo I Rana: 32.6°C (90.7°F)

Sweden

  • Katterjak Airport: 28.3°C (82.5°F)
  • Kvikkjokk: 32.5°C (90.5°F)

Located at an altitude of 1100 meters (3500 feet), Finland's Tarfala Research Station is the coldest long-term reporting site in Lapland, according to weather records expert Maximiliano Herrera. The station hit 23.1°C (73.6°F) on Tuesday, smashing the all-time record of 21.4°C (70.5°F). The overnight low Monday night at Tarfala was a strikingly mild 13.3°C (55.6°F).

More records were smashed on Wednesday, including 33.4°C (92.1°F) at Kevo, Finland—the hottest temperature in reliable records for all of the province of Lapland in Finland, according to Herrera. Other all-time highs in the preliminary list for Wednesday. […]

Has it ever hit 100°F in the Arctic?

The hottest location in the Scandinavian Arctic on Tuesday, according to Michael Theusner (Klimahaus), was Kevo (latitude 69.75°N), with a high of 32.7°F (91.0°F). If you’re wondering whether any place in or very near the Arctic has ever broken 100°F, the answer is yes—but just barely. Back on 23 July 2010, the community of Ust Moma, Russia (latitude 66.27°N, or about eight miles south of the Arctic Circle), got up to 37.8°C (100.04°F), according to weather records expert Maximiliano Herrera. That’s the warmest reliable temperature on record at or north of that latitude, he says, although there’s an equal reading of questionable veracity in the books from Prospect Creek, Alaska, on 27 June 1915. The highest reliable reading north of latitude 67°N appears to be 37.3°C (99.1°F) at Verkhoyansk, Russia (67°33'N), on 25 July 1988. […]

Heat wave rolls onward in East Asia

Extreme heat has gripped parts of East Asia, including Japan and Korea, since last weekend, with several more days of intense heat on tap. The heat wave is being blamed for at least 14 heat-related deaths and thousands of heat-stroke hospitalizations. On Thursday, July 19, Kyoto tied its all-time high temperature for any month, 39.8°C (103.6°F), previously set on July 8, 1994. Kyoto has also beaten its previous all-time high for July (38.3°C/101.0°F from 26 July 2014) on five of the past six days:

  • 38.5°C (101.3°F) on Saturday, July 14
  • 38.7°C (101.7°F) on Sunday, July 15
  • 38.5°C (101.3°F) on Monday, July 16
  • 39.1°C (102.4°F) on Sunday, July 18
  • 39.8°C (103.6°F) on Thursday, July 19

Weather records in Kyoto extend back to 1881.

A number of all-time records set on Monday, July 16, in Japan, although most of the stations have periods of record dating back only to 1976. [more]

(weather.com) – Sweden's most serious rash of wildfires in recent history has prompted a call for help from the European Union amid a record-smashing Scandinavian heat wave that shows no signs of letting up.

At least 40 wildfires were burning in parts of Sweden Wednesday, the Local Sweden reported, prompting evacuations in the Swedish counties of Dalarna, Gävleborg, and Jämtland.

A pair of Italian planes and eight Norwegian helicopters were assisting firefighting efforts, and Sweden's Civil Contingencies Agency requested more aerial assistance from the European Union in what they told the Local Sweden was the nation's most serious wildfire situation of modern times.

This is happening during a heat wave that is smashing some all-time records across parts of Scandinavia.

Kvikkjokk, a village in northern Sweden just north of the Arctic Circle, topped out at 32.5 degrees Celsius, just above 90 degrees Fahrenheit, setting their all-time record high, according to climatologist and world records expert Maximiliano Hererra.

Wednesday, the Kevo observation station in northern Finland set an all-time record for Lapland, reaching 92 degrees, according to the Finnish Meteorological Institute. [more]

Sweden Wildfires Most Serious in Recent Times Aggravated By Record-Smashing Heat, Ongoing Drought With No End in Sight

NOKOMIS, Florida, 11 July 2018 (WWSB) – Mote Marine Laboratory says a sea turtle nest was damaged on 5 July 2018 by suspected poachers.

According to Mote Marine, three suspected poachers dug into the nest and left one broken egg on its surface.

Two members of Mote Marine Laboratory’s nighttime sea turtle tagging team say they saw the perpetrators digging into the nest around 1:30 a.m. As the tagging team got closer, the suspected poachers ran away, and could not be identified.

Mote reported the incident to the Sarasota County Sheriff’s Office and the Florida Fish & Wildlife Conservation Commission.

According to Mote Senior Biologist Melissa Bernhard, intentional poaching of sea turtle nests is rare in Mote’s monitoring area, Longboat Key through Venice, but accidental damage and vandalism are more common.

Last month Mote’s Sea Turtle Patrol found eight sea turtle nests damaged by an all-terrain vehicle or golf cart on Siesta Key.

If you suspect that someone is tampering with a sea turtle nest, harassing a sea turtle or has possession of a sea turtle or any of its parts, please call FWC’s wildlife alert hotline (888-404-FWCC (3922)) or your local sheriff’s department.

SIESTA KEY, Florida (WWSB) – Florida Fish and Wildlife Conservation Commission is investigating after receiving a call of a vehicle riding through several protected sea turtle nests.

The incident happened behind 8550 Sanderling Road, in south Siesta Key. FWC officers received a call about the incident around 8 a.m. on Friday, 22 June 2018, but believe the crime took place the night prior.

Mote Marine Laboratory, based in Sarasota, says one of its researchers discovered the damaged nests and reported the incident to FWC and the Sarasota County Sheriff's Office. According to FWC, at least 8 nests were vandalized.

According to FWC, an ATV or golf cart rode through multiple sea turtle nests. The stakes were also torn down on some of the nests. FWC believes the person or persons involved deliberately vandalized the nests.

Sea turtles, nests, and hatchlings are federally protected. FWC reports the incident is a criminal violation. The person or people responsible could face jail crime or be fined.

No suspects have been named. Anyone with information is asked to contact FWC at 888-404-FWCC.

(Weather Underground) – June 2018 was the planet's fifth-warmest June since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Monday. NASA rated June 2018 as tied for third-warmest June on record. NOAA found that the only warmer June months were 2016, 2015, 2017 and 2014, in that order. Occasional differences in rankings between NASA and NOAA arise mostly due to how they handle data-sparse regions such as the Arctic, where few surface weather stations exist.

Global ocean temperatures during June 2018 were the sixth warmest on record, and global land temperatures were also the sixth warmest on record, according to NOAA. Global satellite-measured temperatures in June 2018 for the lowest 8 km of the atmosphere were the ninth or tenth warmest in the 40-year record, according to the University of Alabama Huntsville (UAH) and RSS, respectively.

Two billion-dollar weather disasters in June 2018

Two billion-dollar weather-related disasters hit the Earth last month, according to the June 2018 Catastrophe Report from insurance broker Aon Benfield: a severe weather outbreak in the U.S. that cost $1.4 billion, and flooding in China’s Yangtze River basin that has cost $1.3 billion since May. In addition, damage claims from a March severe weather outbreak in the U.S. topped the $1 billion mark by the end of June. Here is the list of the twelve billion-dollar weather disasters so far in 2018:

  1. Drought, Argentina and Uruguay, 1/1 – 3/31, $3.9 billion, 0 killed

18 July 2018 (BBC News) – Forest fires raging across Sweden as far north as the Arctic Circle have prompted authorities to ask for international assistance.

On Wednesday afternoon, 44 fires were burning from Lapland in the far north to the southern island of Gotland.

Hot weather and persistent drought are the main causes, and the national weather service has issued fire warnings for almost the entire country.

Italy and Norway have both despatched firefighting aircraft to help.

Sweden said Italy had sent 13 people in two Canadair CL-415 "waterbombers", each of which can carry 6,000 litres of water at a time.

Norway's national broadcaster NRK, meanwhile, reported that 10 helicopters had been despatched to aid its neighbour - six on Tuesday and another four on Wednesday - despite the risk of similar fire outbreaks in Norway itself.

The wildfires have raged in parts for days and without a break in the hot dry weather they have shown little sign of stopping.

Many people have been evacuated from their homes in Sweden, while others have been told to shut off all ventilation to keep smoke outside.

Fire chief Britta Ramberg told Swedish media the fire in Jämtland was "the largest and spreading the fastest". Official advisories said that this blaze grew from 1,600 hectares to 3,000 on Tuesday alone, and that firefighters had been unable to contain it.

Many firefighters were being recalled from holiday to join the operation.

Nine important public warnings have also been issued - a record number - as temperatures have hovered near or exceeded 30C for an extended period. [more]

(Science News) – Air pollution caused 3.2 million new cases of diabetes worldwide in 2016, according to a new estimate.

Fine particulate matter, belched out by cars and factories and generated through chemical reactions in the atmosphere, hang around as haze and make air hard to breathe. Air pollution has been linked to chronic conditions such as heart disease and diabetes (SN: 9/30/17, p. 18), but this study is one of the first attempts to quantify the connection for diabetes. Researchers tracked 1.7 million U.S. veterans for almost a decade to assess their risk of developing diabetes. They also used data from global studies on diabetes risk, as well as air quality data from the U.S. Environmental Protection Agency and NASA, to create equations that analyzed the connection between air pollution exposure and diabetes globally.

The new estimate, reported in July in The Lancet Planetary Health, holds air pollution responsible for about 14 percent of new cases of diabetes worldwide. Factors such as genetics, weight, activity level and diet also influence the risk of the disease, which is on the rise globally. (The World Health Organization estimates that 422 million people now live with type 2 diabetes — up from 108 million in 1980.)

The burden isn’t the same around the globe: Unsurprisingly, countries with high pollution levels, such as Pakistan, India, and China, also have especially high rates of air pollution-linked diabetes. The United States, which now has comparatively clean air, is also high on the list.

Air pollution is triggering diabetes in 3.2 million people each year


ABSTRACT: We examined the relationship of PM2·5 and the risk of incident diabetes in a longitudinal cohort of 1 729 108 participants followed up for a median of 8·5 years (IQR 8·1–8·8). In adjusted models, a 10 μg/m3 increase in PM2·5 was associated with increased risk of diabetes (HR 1·15, 95% CI 1·08–1·22). PM2·5 was associated with increased risk of death as the positive outcome control (HR 1·08, 95% CI 1·03–1·13), but not with lower limb fracture as the negative outcome control (1·00, 0·91–1·09). An IQR increase (0·045 μg/m3) in ambient air sodium concentration as the negative exposure control exhibited no significant association with the risk of diabetes (HR 1·00, 95% CI 0·99–1·00). An integrated exposure response function showed that the risk of diabetes increased substantially above 2·4 μg/m3, and then exhibited a more moderate increase at concentrations above 10 μg/m3. Globally, ambient PM2·5 contributed to about 3·2 million (95% uncertainty interval [UI] 2·2–3·8) incident cases of diabetes, about 8·2 million (95% UI 5·8–11·0) DALYs caused by diabetes, and 206 105 (95% UI 153 408–259 119) deaths from diabetes attributable to PM2·5 exposure. The burden varied substantially among geographies and was more heavily skewed towards low-income and lower-to-middle-income countries. The global toll of diabetes attributable to PM2·5 air pollution is significant. Reduction in exposure will yield substantial health benefits.

(CNN) – Death rates from liver cancer increased 43 percent for American adults from 2000 to 2016, according to a report released Tuesday by the US Centers for Disease Control and Prevention's National Center for Health Statistics. The increase comes even as mortality for all cancers combined has declined.

Liver cancer death rates increased for both men and women 25 and older, as well as white, black and Hispanic people. Only Asians and Pacific Islanders saw a decrease in mortality from liver cancer.

The rise in mortality doesn't mean that liver cancer is deadlier than before, according to Dr. Jiaquan Xu, the author of the report; the 10-year survival rate for liver cancer didn't change much. Rather, the increase in mortality means more people are developing liver cancer.

More than 70% of liver cancers are caused by underlying liver disease, which has risk factors such as obesity, smoking, excess alcohol consumption, and hepatitis B and C infection, said Dr. Farhad Islami, the scientific director of cancer surveillance research at the American Cancer Society.

"I think the main reason for the increase in liver cancer incidence and death rate in the US is the increase in the prevalence of excess body weight and hepatitis C virus infection in baby boomers," said Islami, who authored a study on liver cancer occurrence between 1990 and 2014.

Up until 1992, blood transfusions and organ transplants were not screened for hepatitis C, Xu said. According to the CDC, this was once a common means of hepatitis C transmission. […]

The opioid epidemic might also be at fault, said Dr. Manish A. Shah, a medical oncologist at Weill Cornell Medicine and NewYork-Presbyterian. Hepatitis C, spread by sharing needles, drove elevated rates of liver cirrhosis, or scarring due to damage to the liver, in the 1990s and 2000s, Shah said. Cirrhosis increases the risk for liver cancer, although it is not clear why, he added. [more]

(CDC) – Key findings:

Data from the National Vital Statistics System, Mortality

  • Age-adjusted death rates for liver cancer increased 43%, from 10.5 per 100,000 U.S. standard population to 15.0 for men and 40%, from 4.5 to 6.3 for women, between 2000 and 2016.
  • During 2000–2016, liver cancer death rates decreased 22% for non-Hispanic Asian or Pacific Islander (API) adults, but increased 48% for non-Hispanic white, 43% for non-Hispanic black, and 27% for Hispanic adults.
  • Trends in liver cancer death rates varied by age group, but increasing trends from 2000 through 2016 were observed for adults aged 65–74 and 75 and over.
  • In 2016, among the 50 states and the District of Columbia (D.C.), D.C. had the highest death rate while Vermont had the lowest.

Liver cancer (including intrahepatic bile duct cancer) was the ninth leading cause of cancer death in 2000 and rose to sixth in 2016 (1). Although death rates for all cancer combined have declined since 1990, a recent report documented an increasing trend in liver cancer death rates during 1990–2014 (2,3). In this report, trends in liver cancer death rates are examined by sex, race and Hispanic origin, and age group from 2000 through 2016 for adults aged 25 and over. Death rates in 2016 by state and the District of Columbia (D.C.) are also presented.

Age-adjusted liver cancer death rates increased steadily from 2000 through 2016 for both men and women aged 25 and over.

  • Liver cancer death rates for adults aged 25 and over increased 43% from 7.2 per 100,000 U.S. standard population in 2000 to 10.3 in 2016 (Figure 1).
  • Liver cancer death rates increased 43% from 10.5 in 2000 to 15.0 in 2016 for men and 40% from 4.5 to 6.3 for women.
  • The death rate for men was between 2.0–2.5 times the rate for women throughout the period.

Age-adjusted death rates for liver cancer increased during 2000–2016 for non-Hispanic white, non-Hispanic black, and Hispanic adults but decreased for non-Hispanic Asian or Pacific Islander adults.

  • During 2000–2016, the age-adjusted death rate for liver cancer increased 48% (6.1 per 100,000 U.S. standard population to 9.0) for non-Hispanic white adults and 43% (9.5 to 13.6) for non-Hispanic black adults (Figure 2).
  • While non-Hispanic Asian or Pacific Islander (API) adults had the highest liver cancer death rates during 2000–2014 among the four race and Hispanic-origin groups, this group experienced the only decrease (22%), from 17.5 in 2000 to 13.6 in 2016.
  • The liver cancer death rate increased 27% from 11.5 in 2000 to 14.6 in 2016 for Hispanic adults, surpassing the rate for non-Hispanic API adults in 2016.
  • Non-Hispanic white adults had the lowest death rate among the four racial and ethnic groups throughout the period.

Death rates for liver cancer increased from 2000 through 2016 for age groups 65–74 and 75 and over.

  • For adults aged 25–44, the rate remained essentially unchanged during 2000–2016 (Figure 3).
  • For adults aged 45–54, the rate increased 31% from 2000 to 2005, remained stable from 2005 to 2012, and then decreased 20%, from 5.5 per 100,000 population in 2012 to 4.4 in 2016.
  • For adults aged 55–64, the rate increased 109% from 9.3 in 2000 to 19.4 in 2013, but remained stable through 2016.
  • For adults aged 65–74, the rate increased 7%, from 18.7 in 2000 to 20.0 in 2008, and 37% from 20.0 in 2008 to 27.3 in 2016. The rate increased 35% (29.8 in 2000 to 40.2 in 2016) for adults aged 75 and over.
  • The liver cancer death rate was the highest for adults aged 75 and over, followed by age groups 65–74, 55–64, 45–54, and 25–44.

Summary

This report provides the most recent trends in liver cancer mortality by sex, race and Hispanic origin, and age group for adults aged 25 and over. From 2000 through 2016, death rates increased significantly for both men and women, with the death rate for men between two and two and a half times the rate for women. Liver cancer death rates increased for non-Hispanic white, non-Hispanic black, and Hispanic adults, but declined for non-Hispanic API adults. The rate for non-Hispanic white adults aged 25 and over was the lowest of the four race and Hispanic-origin groups from 2000 through 2016, while the rate for non-Hispanic API adults was the highest from 2000 through 2014. The death rate for Hispanic adults surpassed the rate for non-Hispanic API adults in 2016, thus becoming the highest among the four race and ethnicity groups. From 2000 to 2016, death rates for liver cancer increased significantly for age groups 65–74 and 75 and over. The rate for adults aged 45–54 initially increased, but then decreased significantly since 2012. Liver cancer death rates in 2016 varied by jurisdiction, with the lowest death rate in Vermont and the highest in D.C.
