Tiny
particles suspended in the air, known as aerosols, can darken snow
and ice causing it to absorb more of the sun’s energy. But until
recently, scientists rarely considered the effect of all three major
types of light-absorbing aerosols together in climate models.
In
a new study, NASA scientists used a climate model to examine the
impact of this snow-darkening phenomenon on Northern Hemisphere
snowpacks, including how it affects snow amount and heating on the
ground in spring.
Wildfires
have burned a phenomenal 5.5 million acres across the U.S. so far
this year, an area equal to the size of New Jersey.
This
is the second-highest total in at least the past 25 years, according
to data from the National Interagency Fire Center in Boise. Only
2011, which saw 5.8 million acres charred as of July 23 of that year,
had more. On average, at this point in the year, 3.5 million acres
would have burned.

Um,
guys? This winter could be a disaster! But the skiing is probably
going to be insane.
Three
of the official climate reporting organizations around the world,
including the Japan Meteorological Agency, NASA and the National
Oceanic and Atmospheric Administration (NOAA), have each found that
June was the Earth's warmest such month on record.
At
this time of year, the largest colony of nesting birds on Florida’s
Gulf Coast is usually squawking up a storm on Seahorse Key. Thousands
of egrets, ibises, pelicans, cormorants, and other species come to
this strip of sand and mangroves to raise their chicks. Or they did,
until one day this April when all of a sudden—*Detective Caruso
puts on sunglasses*—the birds flew the coop.
“It’s
completely empty,” says wetland ecologist Peter Frederick, “and
silent.”
Leaving
their nests behind—eggs and all—the birds just up and left like
daddy going out for a pack of cigarettes. It’s what Andrew Gude,
manager of the Cedar Keys National Wildlife Refuge, calls
“catastrophic nesting-island abandonment.”
A
new report says the destruction of the arctic’s boreal forests by
fire is occurring at a pace not seen in 10,000 years. Fires are
currently burning in Montana and the Pacific Northwest, a by-product
of extraordinary summer warmth and a lack of rain. But, what’s
happened farther north in Alaska and Canada during the 2015 fire
season is even more horrific and is laid out in a new report from
NOAA-the National Oceanic and Atmospheric Administration. More than
5-million acres have been consumed by fire across Alaska this
wildfire season, 200,000 acres away from making this the 2nd worst
fire season on the books. The situation in western Canada is equally
dire. While 8,100 acres have burned by late July on average, this
year’s tally is more than 15,000 acres–an area greater than the
size of Maryland.
Satellite
imagery has monitored the global spread of smoke off North America’s
fires the past few monthster could be a disaster! But the skiing is
probably going to be insane.

Studies) at the University of Wisconsin-Madison tracks the smoke

Record
warmth playing a major role; NOAA, NASA and the Japanese
Meteorological Agency indicate the opening half of 2015 already one
for the books after a record warm June
June
2015 was the warmest globally on record. Maps of both agency’s
analyses of global temps in June appear immediately below.
Climate Progress has issued a quite a report on the year’s
abnormally warm temp trend which you can examine by

The
disconnect is breathtaking! When! not if, the planet heats up over 5C
the entire biosphere will have unraveled and their won't be a
vertebrate left on the planet. Hard to understand how only $4.2
trillion could be lost when the only species operating in the
monetary realm will be extinct!

Investments
in fossil fuel companies face serious risk from global warming,
research by the Economist Intelligence Unit shows
OUR
greenhouse gas emissions are boosting a vortex of winds around
Antarctica. As this maelstrom accelerates, it shrinks, dragging rain
away from Western Australia.
Earlier
studies suggested that the hole in the ozone layer above Antarctica
was boosting the winds. Now Nerilie Abram of the Australian National
University in Canberra and her colleagues have shown that global
warming is just as important.
The
team reconstructed Antarctic temperatures over the past 1000 years
using an ice core. The temperatures correlate with wind strength, and
the team found that the winds are now the strongest they have been in
the past millennium. But the gain in strength began in the 1940s,
decades before the ozone hole. So the team simulated weather patterns
in the last 1000 years using climate models and greenhouse gas levels
from ice cores. All the models predicted that the winds would pick up
by the 1940s, suggesting that greenhouse gases were playing a role

“Global
coal demand is slowing fast,” is the headline in a June Business
Insider Australia story. “The global coal renaissance is the most
important climate story today,” is the headline in a July Vox
story.
Which
is correct? Mostly the first one. There was a true global coal
renaissance starting around the year 2000, a resurgence due primarily
to China. But it is now stalling.
Earlier
this week, I wrote about the
global coal renaissance —
arguably the most important climate-change story in the world right
now. Since 2000, developing countries like China, India,
Vietnam, and Indonesia have been building coal-fired power plants at
a rapid pace:
On
the upside, this boom has helped these countries lift themselves out
of poverty. But the growth in coal has also meant a
surge in global carbon-dioxide emissions — and if coal continues to
be the world's energy source of choice, we'll have little hope
avoiding drastic global warming.
So
that brings us to the next question: How long will this global
coal boom continue?

AUSTRALIA: 12:30pm
update: Very cold air over Victoria and especially Tasmania today in
the wake of the strong cold front ****
The
strong front moved through overnight leaving very cold air in its
wake the centre of the deep Low is situated about 150-200km south of
Tasmania, we have seen wind gusts to 143km/h over Maatsuyker Island,
91km/h in Hobart. In Victoria there has also been 100km/h+ gusts with
Hogan island seeing 132km/h gust and Wilson Prom 115km/h. There has
also been close to 100km/h wind gusts on the west coast.
Showers,
local hail and thunder have also been observed especially in the west
and low level snow especially in Tasmania with snow being observed at
Cradle mountain
The
colder air and strong wind will also push into NSW with strong winds
expected south of the Hunter in NSW today including the Sydney
region.
In
terms of rainfall Parafield saw one of the higher totals in SA with
19mm to 9am, in Tasmania Luncheon hill received 23mm and Scotts Peak
22mm to 9am & Victoria Cape Otway and Mt Buller received 19mm
with Port Fairy recording 16mm to 9am.
Conditions
will begin to ease tonight and mostly tomorrow as a high pushes in
from the west.

Tropical disturbance forаing near Solomon Islands
Could it be?? Modelling has been suggesting the chance of yet another wintertime tropical disturbance forming near the Solomon Islands area this week.At this stage, it looks like the last system i.e. it could eventually drift towards the far northeast corner of the Coral Sea but with high uncertainty as to whether it'll strengthen to anything more than a tropical low.Here's a short animation of forecast infrared satellite imagery for the next 10 days generated by GFS model data (and displayed via tropicaltidbits). You can see the disturbance taking shape out there.... P.S. hover your mouse over the video and click on the HD option in the lower right (Ken):
