Tropical forest the size of England destroyed in 2018: report

Published

on

Last year humanity destroyed an expanse of tropical forest nearly the size of England, the fourth largest decline since global satellite data become available in 2001, researchers reported Thursday.

The pace of the loss is staggering — the equivalent of 30 football fields disappearing every minute of every day in 2018, or a total of 120,000 square kilometers (46,000 square miles).

Almost a third of that area, some 36,000 km2, was pristine primary rainforest, according to the annual assessment from scientists at Global Forest Watch, based at the University of Maryland.

“For the first time, we can distinguish tree cover loss within undisturbed natural rainforests, which contain trees that can be hundreds, even thousands, of years old,” team manager Mikaela Weisse told AFP.

Rainforests are the planet’s richest repository of wildlife and a critical sponge for soaking up planet-heating CO2.

Despite a slew of counter-measures at both the national and international level, deforestation has continued largely unabated since the beginning of the century.

Global forest loss peaked in 2016, fueled in part by El Nino weather conditions and uncontrolled fires in Brazil and Indonesia.

The main drivers are the livestock industry and large-scale commodity agriculture — palm oil in Asia and Africa, soy beans and biofuel crops in South America.

Small-scale commercial farming — of cocoa, for example — can also lead to the clearing of forests.

A quarter of tropical tree cover loss in 2018 occurred in Brazil, with the Democratic Republic of Congo and Indonesia each accounting for about 10 percent.

Malaysia and Madagascar also saw high levels of deforestation last year.

Nearly a third of primary forest destruction took place in Brazil (13,500 km2), with the Democratic Republic of Congo (4,800 km2), Indonesia (3,400 km2), Colombia (1,800 km2) and Bolivia (1,500 km2) rounding out the top five.

Madagascar lost two percent of its entire rainforest in 2018.

“The world’s forests are now in the emergency room,” said Frances Seymour, a distinguished senior fellow at the World Resources Institute, an environmental policy think tank based in Washington DC.

“The health of the planet is at stake, and band aid responses are not enough,” she added.

“With every hectare lost, we are that much closer to the scary scenario of runaway climate change.”

Globally, forests absorb about 30 percent of manmade greenhouse gas emissions, just over 11 billion tonnes of C02 a year.

Oceans are also a major “sink”, soaking up another 23 percent.

Burning or clear-cutting vast tracts of tropical forest not only releases carbon into the atmosphere, it reduces the size of the sponge that can absorb CO2.

One bright spot in the report was Indonesia, which lost 3,400 km2 of primary forest in 2018 — a 63 percent drop compared to 2016.

In 2015, massive forest fires on Sumatra, Borneo and other Indonesian islands levelled 20,000 km2 and generated health-wrecking pollution over a large swathe of Southeast Asia.

In Brazil, however, trend lines are moving in the wrong direction.

“Our data shows a big spike in forest loss in 2016 and 2017 related to manmade fires,” Weisse said of Brazil.

“Shockingly, we are also seeing invasions into indigenous lands that have been immune to deforestation for years.”

Brazil’s President Jair Bolsonaro, who come into office in January, has vowed to curtail environmental regulations and allow commercial farming and mining on indigenous reserves, which comprise more than 10 percent of Brazil’s territory.

The researchers emphasised that Bolsonaro has not been in office long enough to assess the impacts of his policies on deforestation.

In West Africa, meanwhile, 70 percent of primary forest loss in Ghana and Ivory Coast occurred in protected areas, pointing up the need for stricter enforcement.

White losers have always tried to punish black election winners — Mississippi case just the latest example

Published

on

The recent experience of Hester Jackson-McCray, a black Democrat who narrowly defeated a Republican incumbent in a Mississippi statehouse race, echoes America's long history of criminalizing black politicians.

GOP legislator Ashley Henley, who lost by 14 votes, asked the Republican-controlled statehouse to overturn the results based on her claims of election irregularities, and that's not the first time in U.S. history that whites have sought to punish black politicians for winning, reported The Guardian.

Rick Wilson: Doug Collins is a ‘screeching histrionic drama queen’ who’s ‘waving’ his ‘junk around’

Published

on

Republican strategist Rick Wilson had a few carefully chosen words for the Ranking Member of the House Judiciary Committee, Rep. Doug Collins, Thursday night after a 13-hour day of impeachment debate that featured repeated outbursts, stonewalling, and theatrics from the Republican Member from Georgia.

"I don't want to say that Doug Collins is a screeching, histrionic drama queen, because that would insult screeching, histrionic drama queens," Wilson said on MSNBC's "The 11th Hour," "but this whole thing is a bad faith effort, performative in every way."

Wilson, author of the book, Everything Trump Touches Dies, was far from done.

Trump is wallowing in ‘self-pity’ even though McConnell promised to protect him: Morning Joe

Published

on

Appearing on MNBC's "Morning Joe," New York Times reporter Peter Baker said Donald Trump is wallowing in "self-pity" that fluctuates with "combativeness" as he worries about the effect being impeached will have on his legacy.

Speaking with host Joe Scarborough, Baker filled in the blanks from his Times report, saying the president is obsessed with the impeachment hearings and Senate trial still to come.

Asked by host Scarborough about Trump's "humiliation," Baker said, "He can count on the Republican-controlled Senate to hold the trial where he seems almost certain to be acquitted, or at least see the charges dismissed in some fashion."
