Rise in CO2 has 'greened Planet Earth' - BBC News

Rise in CO2 has 'greened Planet Earth'
25 April 2016From the section Science & Environment
Carbon dioxide emissions from industrial society have driven a huge growth in trees and other plants.
A new study says that if the extra green leaves prompted by rising CO2 levels were laid in a carpet, it would cover twice the continental USA.
Climate sceptics argue the findings show that the extra CO2 is actually benefiting the planet.
But the researchers say the fertilisation effect diminishes over time.
They warn the positives of CO2 are likely to be outweighed by the negatives.
The lead author, Prof Ranga Myneni from Boston University, told BBC News the extra tree growth would not compensate for global warming, rising sea levels, melting glaciers, ocean acidification, the loss of Arctic sea ice, and the prediction of more severe tropical storms.
The new study is published in the journal Nature Climate Change by a team of 32 authors from 24 institutions in eight countries.
It is called Greening of the Earth and its Drivers, and it is based on data from the Modis and AVHRR instruments which have been carried on American satellites over the past 33 years.The sensors show significant greening of something between 25% and 50% of the Earth's vegetated land, which in turn is slowing the pace of climate change as the plants are drawing CO2 from the atmosphere.
Just 4% of vegetated land has suffered from plant loss.
This is in line with the Gaia thesis promoted by the maverick scientist James Lovelock who proposed that the atmosphere, rocks, seas and plants work together as a self-regulating organism. Mainstream science calls such mechanisms "feedbacks".
The scientists say several factors play a part in the plant boom, including climate change (8%), more nitrogen in the environment (9%), and shifts in land management (4%).
But the main factor, they say, is plants using extra CO2 from human society to fertilise their growth (70%).
Harnessing energy from the sun, green leaves grow by using CO2, water, and nutrients from soil.
"The greening reported in this study has the ability to fundamentally change the cycling of water and carbon in the climate system," said a lead author Dr Zaichun Zhu, from Peking University, Beijing, China.
The authors note that the beneficial aspect of CO2 fertilisation have previously been cited by contrarians to argue that carbon emissions need not be reduced.
Co-author Dr Philippe Ciais, from the Laboratory of Climate and Environmental Sciences in Gif-sur‑Yvette, France (also an IPCC author), said: "The fallacy of the contrarian argument is two-fold. First, the many negative aspects of climate change are not acknowledged.
"Second, studies have shown that plants acclimatise to rising CO2 concentration and the fertilisation effect diminishes over time." Future growth is also limited by other factors, such as lack of water or nutrients.
A co-author Prof Pierre Friedlingstein, from Exeter University, UK, told BBC News that carbon uptake from plants was factored into Intergovernmental Panel on Climate Change (IPCC) models, but was one of the main sources of uncertainty in future climate forecasts.
Warming the Earth releases CO2 by increasing decomposition of soil organic matter, thawing of permafrost, drying of soils, and reduced photosynthesis - potentially leading to tropical vegetation dieback.
He said: "Carbon sinks (such as forests, where carbon is stored) would become sources if carbon loss from warming becomes larger than carbon gain from fertilisation.
"But we can't be certain yet when that would happen. Hopefully, the world will follow the Paris agreement objectives and limit warming below 2C."
Nic Lewis, an independent scientist often critical of the IPCC, told BBC News: "The magnitude of the increase in vegetation appears to be considerably larger than suggested by previous studies.
"This suggests that projected atmospheric CO2 levels in IPCC scenarios are significantly too high, which implies that global temperature rises projected by IPCC models are also too high, even if the climate is as sensitive to CO2 increases as the models imply."
And Prof Judith Curry, the former chair of Earth and atmospheric sciences at the Georgia Institute of Technology, added: "It is inappropriate to dismiss the arguments of the so-called contrarians, since their disagreement with the consensus reflects conflicts of values and a preference for the empirical (i.e. what has been observed) versus the hypothetical (i.e. what is projected from climate models).
"These disagreements are at the heart of the public debate on climate change, and these issues should be debated, not dismissed."

NY mountain hits minus -114 degrees wind chill at summit

Listen to Military Veteran Talk Radio 

www.nydailynews.com
While New York City had its coldest start to Valentine’s Day in 100 years on Sunday, it would seem balmy compared with the wicked wind chill at upstate Whiteface Mountain.
As temperatures dropped across the Northeast from the blast of a polar vortex, the wind chill at Whiteface, near Lake Placid, made it feel like a body- and mind-numbing minus 114 degrees late Saturday and into Sunday. Central Park could only muster a minus 1 degree.
The Wild Center, which works with the Atmospheric Science Research Center at SUNY Albany, recorded the frigid temperature from a research station at the mountain’s summit.
The Wild Center This is what happens when a tree is exposed to minus 114 degrees wind chill at Whiteface Mountain's summit.
“The extreme temperatures (Saturday) night on Whiteface have to do with its elevation, 4,865 feet and the wind speed,” Tracey Legat, the center’s communications manager at the center told the Daily News. “The mountains of the Adirondacks are often some of the coldest places in the lower 48 states during the year.”
The Wild Center Winds at Whiteface Mountain's summit blasted at 45 mph on Saturday night going into Sunday morning.
The Arctic winds howled through the summit at about 45 mph, freezing almost everything in their path.
The center managed to capture a photo of a tree being turned into a popsicle as the winds formed “monstrous rime ice” around it.
The Wild Center On Sunday morning, the wind chill on Whiteface Mountain's summit was colder than the windchill in Antarctica.
The mountain’s summit was actually colder than Antarctica on Sunday, according to the National Weather Service.

George Soros Sees Crisis in Global Markets That Echoes 2008

www.bloomberg.com

Global markets are facing a crisis and investors need to be very cautious, billionaire George Soros told an economic forum in Sri Lanka on Thursday.

China is struggling to find a new growth model and its currency devaluation is transferring problems to the rest of the world, Soros said in Colombo. A return to positive interest rates is a challenge for the developing world, he said, adding that the current environment has similarities to 2008.

Global currency, stock and commodity markets are under fire in the first week of the new year, with a sinking yuan adding to concern about the strength of China’s economy as it shifts away from investment and manufacturing toward consumption and services. Almost $2.5 trillion was wiped from the value of global equities this year through Wednesday, and losses deepened in Asia on Thursday as a plunge in Chinese equities halted trade for the rest of the day.

“China has a major adjustment problem,” Soros said. “I would say it amounts to a crisis. When I look at the financial markets there is a serious challenge which reminds me of the crisis we had in 2008.”

Soros has warned of a 2008-like catastrophe before. On a panel in Washington in September 2011, he said the Greece-born European debt crunch was “more serious than the crisis of 2008.”

Soros, whose hedge-fund firm gained about 20 percent a year on average from 1969 to 2011, has a net worth of about $27.3 billion, according to the Bloomberg Billionaires Index. He began his career in New York City in the 1950s and gained a reputation for his investing prowess in 1992 by netting $1 billion with a bet that the U.K. would be forced to devalue the pound.

Measures of volatility are surging this year. The Chicago Board Options Exchange Volatility Index, known as the fear gauge or the VIX, is up 13 percent. The Nikkei Stock Average Volatility Index, which measures the cost of protection on Japanese shares, has climbed 43 percent in 2016 and a Merrill Lynch index of anticipated price swings in Treasury bonds rose 5.7 percent.

China’s Communist Party has pledged to increase the yuan’s convertibility by 2020 and to gradually dismantle capital controls. Weakness in the world’s second-largest economy remains even after the People’s Bank of China has cut interest rates to record lows and authorities pumped hundreds of billions of dollars into the economy. Data this week reinforced a sluggish manufacturing sector.

Armed group takes over Oregon wildlife refuge building - CNN.com


edition.cnn.com

www.oregonlive.com

One of them is Ammon Bundy, the 40-year-old son of Nevada rancher Cliven Bundy, who is well-known for anti-government action.

He spoke by phone to CNN Sunday morning. Asked several times what he and those with him want, he answered in vague terms, saying that they want the federal government to restore the "people's constitutional rights."

"This refuge -- it has been destructive to the people of the county and to the people of the area," he said.

"People need to be aware that we've become a system where government is actually claiming and using and defending people's rights, and they are doing that against the people."

The group is occupying part of the Malheur National Wildlife Refuge near Burns after gathering outside for a demonstration supporting Dwight and Steven Hammond, father-and-son ranchers who were convicted of arson.

Prosecutors said the Hammonds set a fire that burned about 130 acres in 2001, to cover up poaching. They were sentenced to five years in prison.

The Hammonds, who are set to turn themselves in Monday afternoon, have said they set the fire to reduce the growth of invasive plants and to protect their property from wildfires, CNN affiliate KTVZ reported.

The Hammonds have been clear in that they don't want help from the Bundy group.

"Neither Ammon Bundy nor anyone within his group/organization speak for the Hammond family," the Hammonds' attorney W. Alan Schroeder wrote to Harney County Sheriff David Ward.

CNN law enforcement analyst Art Roderick, a retired U.S. marshal who investigated anti-government militias for years, warned that Bundy's call for supporters to join him might "turn into a bad situation."

"What's going to happen hopefully (is) ... we don't go out there with a big force, because that's what they're looking for," he said. "The last thing we need is some type of confrontation."

He said that over the years, law enforcement has learned how to handle a situation like this; one that hasn't erupted in violence and in which a law may be broken, but there's no immediate threat to anyone's life.

The best approach now, Roderick said, is to wait the group out and to figure out how to bring a peaceful end to the standoff.

'We are not terrorists'

After the march Saturday, the armed protesters broke into the refuge's unoccupied building and refused to leave. Officials have said there are no government employees in the building.

"We will be here as long as it takes," Bundy said. "We have no intentions of using force upon anyone, (but) if force is used against us, we would defend ourselves."

Ammon Bundy said that the group in Oregon was armed, but that he would not describe it as a militia. He declined to say how many people were with him, telling CNN on Sunday that giving that information might jeopardize "operational security."

The elder Bundy drew national attention last year after staging a standoff with federal authorities over a Bureau of Land Management dispute.

"We are not terrorists," Ammon Bundy said. "We are concerned citizens and realize we have to act if we want to pass along anything to our children."

He wouldn't call his group a militia, but others are.

"I don't like the militia's methods," local resident Monica McCannon told KTVZ. "They had their rally. Now it's time for them to go home. People are afraid of them."

A U.S. Fish and Wildlife Service representative said the agency and the Bureau of Land Management are aware of the armed protesters.

"While the situation is ongoing, the main concern is employee safety, and we can confirm that no federal staff were in the building at the time of the initial incident," the representative said. "We will continue to monitor the situation."

What the protesters want

When asked what it would take for the protesters to leave, Bundy did not offer specifics. He said he and those with him are prepared to stay put for days or weeks.

"We feel that we will occupy this as long as necessary," he said.

"We are using the wildlife refuge as a place for individuals across the United States to come and assist in helping the people of Harney County claim back their lands and resources," he said.

"The people will need to be able to use the land and resources without fear as free men and women. We know it will take some time."

He did not explicitly call on authorities to commute the prison sentences for the Hammonds, but he said their case illustrates officials' "abuse" of power.

"Now that people such as the Hammonds are taking a stand and not selling their ranches, they are being prosecuted in their own courts as terrorists and putting them in prison for five years," Bundy said.

He said the Malheur National Wildlife Refuge has taken over the space of 100 ranches since the early 1900s.

"They are continuing to expand the refuge at the expense of the ranchers and miners," Bundy said.

He also said Harney County, in southeastern Oregon, went from one of the state's wealthiest counties to one of the poorest.

CNN has not independently corroborated Bundy's claims.

"I want to emphasis that the American people are wondering why they can't seem to get ahead or why everything is costing more and you are getting less, and that is because the federal government is taking and using the land and resources," Bundy said.

"And if it is continued, it will put the people in poverty."

What the feds say

Acting U.S. Attorney Billy J. Williams of Oregon gave a starkly different perspective on the arson case.

His office declined to comment on the situation at the wildlife refuge Saturday, but it cited an opinion piece written by Williams in the Burns Times Herald last month defending the federal prosecutors' actions in the Hammonds case.

"Five years ago, a federal grand jury charged Dwight and Steven Hammond with committing arson on public lands and endangering firefighters," Williams wrote for the newspaper. "Steven Hammond was also found guilty of committing a second arson in 2006."

The prosecutor said witnesses saw the Hammonds illegally slaughter a herd of deer on public land.

"At least seven deer were shot with others limping or running from the scene," Williams wrote.

He said a teenage relative of the Hammonds testified that Steven Hammond gave him a box of matches and told him to start the blaze. "The fires destroyed evidence of the deer slaughter and took about 130 acres of public land out of public use for two years," the prosecutor wrote.

Williams also disputed the notion that the Hammonds were prosecuted as terrorists, as Bundy suggested.

"The jury was neither asked if the Hammonds were terrorists, nor were defendants ever charged with or accused of terrorism," Williams wrote. "Suggesting otherwise is simply flat-out wrong."

CNN's Holly Yan, Evan Perez, Kevin Liptak, Kevin Bohn and Jackie Castillo contributed to this report.

Militia takes over Malheur National Wildlife Refuge headquarters

www.oregonlive.com

Update at 9:15 p.m.: Statement from Harney County Sheriff Dave Ward: "After the peaceful rally was completed today, a group of outside militants drove to the Malheur Wildlife Refuge, where they seized and occupied the refuge headquarters. A collective effort from multiple agencies is currently working on a solution. For the time being please stay away from that area. More information will be provided as it becomes available. Please maintain a peaceful and united front and allow us to work through this situation."

The Bundy family of Nevada joined with hard-core militiamen Saturday to take over the headquarters of the Malheur National Wildlife Refuge, vowing to occupy the remote federal outpost 30 miles southeast of Burns for years.

The occupation came shortly after an estimated 300 marchers — militia and local citizens both — paraded through Burns to protest the prosecution of two Harney County ranchers, Dwight Hammond Jr. and Steven Hammond, who are to report to prison on Monday.

Among the occupiers is Ammon Bundy, son of Nevada rancher Cliven Bundy, and two of his brothers. Militia members at the refuge claimed they had as many as 100 supporters with them. The refuge, federal property managed by the U.S. Fish and Wildlife Service, was closed and unoccupied for the holiday weekend.

In phone interviews from inside the occupied building Saturday night, Ammon Bundy and his brother, Ryan Bundy, said they are not looking to hurt anyone. But they would not rule out violence if police tried to remove them, they said.

"The facility has been the tool to do all the tyranny that has been placed upon the Hammonds," Ammon Bundy said.

"We're planning on staying here for years, absolutely," he added. "This is not a decision we've made at the last minute."

Neither man would say how many people are in the building or whether they are armed. Ryan Bundy said there were no hostages, but the group is demanding that the Hammonds be released and the federal government relinquish control of the Malheur National Forest.

He said many would be willing to fight — and die, if necessary — to defend what they see as constitutionally protected rights for states, counties and individuals to manage local lands. 

"The best possible outcome is that the ranchers that have been kicked out of the area, then they will come back and reclaim their land, and the wildlife refuge will be shut down forever and the federal government will relinquish such control," he said. "What we're doing is not rebellious. What we're doing is in accordance with the Constitution, which is the supreme law of the land." 

Government sources told The Oregonian/OregonLive that the militia also was planning to occupy a closed wildland fire station near the town of Frenchglen. The U.S. Bureau of Land Management posts crews there during the fire season.

Law enforcement officials so far have not commented on the situation. Oregon State Police, the Harney County Sheriff's Office and the FBI were involved.

Ammon Bundy posted a video on his Facebook page calling on patriots from across the country to report to the refuge – with their weapons.

The dramatic turn came after other militia groups had tried to dampen community concerns they meant trouble.

Warmest Christmas Eve on record to unfold across eastern US

www.accuweather.com

Any hopes of a white Christmas that the weekend chill brought will be dashed in the eastern United States, with this Christmas Eve shaping up to be the warmest on record in many communities.

According to AccuWeather Senior Meteorologist Tom Kines, "On Christmas Eve, parts of the mid-Atlantic and New England could be just as warm as they were on the Fourth of July."

Record high temperatures, including some record warm minimum temperatures, are likely to be set from Florida to Maine.

Balmy Christmas Eve

According to AccuWeather Chief Long Range Meteorologist Paul Pastelok, "On Christmas Eve, daily record highs may be broken in the morning, followed by monthly record highs in the afternoon."

Records in the major cities of the Eastern states date back to the middle 1800s.

Another northward bulge in the jet stream will be responsible for the warmth in the East this week.

The jet stream is a strong river of air high in the atmosphere that guides weather systems and separates warm air to the south from cold air to the north.

Christmas Eve will feel more like Easter with highs ranging from the 50s in Maine to the 70s in the mid-Atlantic and the lower 80s in parts of the Southeast. That equates to highs that are 15 to 35 degrees Fahrenheit above normal.

"Temperatures could touch 80 as far north as the mid-Atlantic states," Pastelok said.

Widespread record highs will not only be challenged but also shattered in many towns and cities. The potential exists for records to be topped by more than 10 degrees from Atlanta to Washington, D.C., to Philadelphia to New York City and to Burlington, Vermont.

"It appears high temperatures will be in the 70s on Christmas Eve in New York City, which is about 35 degrees above normal for the date," AccuWeather Meteorologist Bill Deger said. "It was also unusually warm last Christmas Eve in 2014, when Central Park reached 58 F for a high."

Subtropical air will be drawn northward along with the warmth and will make it feel humid to some people.

Along with erasing any hopes for a white Christmas, the warmth will mean residents can leave the heavy winter jackets, hats or mittens at home when heading out for last-minute shopping or to Christmas Eve services.

The only chance of a white Christmas will be in the Tug Hill region of New York state, east of Lake Ontario, and northern Maine, where old snow may remain on the ground.

The warmth will come despite some clouds and a couple of showers in the area. Those wanting to take advantage of the warmth by caroling, taking a walk, firing up the grill or engaging in any other outdoor activity should plan to keep an umbrella handy.

The passage of a cold front will ease the extreme warmth in the Northeast for Christmas Day, but temperatures will still be well above normal for the holiday. In the Southeast, Friday will likely be a repeat of Thursday.

Since temperatures will be so high during the overnight hours on Thursday, record highs for Christmas day may be set before dawn in a number of locations.

According to AccuWeather Meteorologist Ed Vallee, the return of persistent cold will not be the theme for the remainder of 2015.

"The extreme warmth of late will certainly be muted after Christmas Day, but above-average temperatures continuing through the end of the month will set the stage for December monthly temperature records to be broken in some areas of the East," he said.
