As wildfires continue to burn in Australia, smoke from the blazes has
traveled thousands of miles across the ocean to Chile. The plumes crossed
11,000 kilometers (6,800 miles) over the Pacific Ocean to the South
American nation, moving on what is known as a trough or channel of low
atmospheric pressure.

Edita Amador, a meteorologist for Chile's Weather Directorate, told the
Australian Associated Press she expects the cloud to head towards
Argentina in the coming days. She explained it may form a "cap" over the
land, which could reduce ultraviolet radiation levels on the ground.
Amador said the smoke shouldn't cause problems as it rarely rains in the
affected area.

On Monday, the U.S. National Oceanic and Atmospheric Administration
tweeted a satellite image showing two areas of smoke from the bush fires,
heading towards South America.

"The smoke is in the process of circumnavigating the #planet," it wrote.

This morning, #GOESEast spied two areas of #smoke that originated from the
#AustralianBushFires. The smoke is in the process of circumnavigating the
#planet.

The mass of particles had previously turned skies above New Zealand
orange, as the country deals with its own bushfires. On Sunday, New
Zealand's Met Service shared a satellite image showing "a significant
cloud of smoke blowing over New Zealand from Australia." It said, "This
has led to the widespread reports of orange skies today."

As well painting skies an eerie colour, the fires have pumped huge amounts
of carbon dioxide into the atmosphere. In mid-December, Niels Andela, a
scientist at the NASA Goddard Space Flight Centre who works on the Global
Fire Emissions Database, told The Guardian the fires had released the
equivalent of almost half of the country's annual CO2 emissions since
August. The 250 million metric tons came from fires in New South Wales and
Queensland. Since then, data suggests 349 million metric tons have been
let off.

Scientists working with the database make their calculations using
satellite data on burning areas and past estimates on emissions from
fires. At the time, Andela said the method is still being developing
meaning it presents uncertainties, but that approach is "widely applied."

According to Andela, since August 1 fires in New South Wales have released
260 million metric tons of CO2 emissions, 9 million metric tons in
Victoria, 4 million metric tons in South Australia, and 76 million metric
tons in Queensland.

He said plants usually soak up CO2 emissions from grassland and savanna
fires. But it could be decades before scorched forests grow back and
regain the ability to absorb greenhouse gases.

As of Tuesday evening in Australia, the Australian Associated Press
reported bushfires continued to ravage Queensland, Western Australia,
Tasmania, New South Wales, Victoria, and South Australia.

Donald J. Trump, 304 electoral votes to 227, defeated compulsive liar in
denial Hillary Rodham Clinton on December 19th, 2016. The clown car
parade of the democrat party ran out of gas and got run over by a Trump
truck.

Congratulations President Trump. Thank you for cleaning up the disaster
of the Obama presidency.

Under Barack Obama's leadership, the United States of America became the
The World According To Garp.

Obama sold out heterosexuals for Hollywood queer liberal democrat donors.

President Trump has boosted the economy, reduced illegal immigration,
appointed dozens of judges and created jobs.
