See just how little multi-year ice there is
Arctic Sea Ice Age - September 2015 to May 2017
Here are some of the main headlnes.
May Was Earth's Second-Warmest in 137 Years; Only 2016 Was Hotter
May Was Earth's Second-Warmest in 137 Years; Only 2016 Was Hotter
NASA's
Goddard Institute for Space Studies calculated the Earth's mean
temperature over land and water in May was 0.88 degrees Celsius above
the 1951-1980 average, second only to May 2016's 0.93 degree Celsius
departure from average. May 2017 beat out May 2014 by just 0.01
degrees Celsius for the second-place ranking.
This
is the fifth month so far this year to rank among the top three
warmest on record for each respective month. February, March and
April 2017 ranked as second-warmest, while January 2017 finished in
third place.
The
largest May warm temperature anomalies were in western Europe,
northern Africa, Asia, eastern South America, northern Alaska,
northern Canada and near Antarctica. Northern Russia was the most
significantly cooler-than-average location.
Scorching May continues decades-long streak of above-average months, and global warming is only accelerating
But before our millennial readers start writing us that the term generally refers to people born starting in the early 1980s, consider this: July 1985 is only a cooler-than-average month if you use the base period 1951 to 1980, as NASA does for its data. But humans were warming the planet by burning fossil fuels long before then — the Industrial Revolution began over two centuries ago.
So when you use an 1880 to 1899 baseline to reflect the earlier warming, as Schmidt does in the graph above, you see we have to go back much further to find a colder than average year — or month.
Climate Central looked at the monthly data using the earlier baseline and found that “if you were born after December 1964, you’ve never experienced a month cooler than average on this planet.”
From
Antarctica, where a research expedition was canceled due to rising
temperatures, to the Arctic Sea, where ice continues to melt, the
effects of climate change are being felt around the globe. In the
United States, temperatures are rising and coastlines are
disappearing. One of the areas that has been affected the most is
Louisiana, the coastline of which has been in danger for years.
According to a new study reported on by the New Orleans
Times-Picayune, the danger is greater than anyone realized
It’s
common knowledge that the coast of Louisiana is quietly sinking into
the balmy Gulf waters. But new research suggests we may have been
underestimating how quickly it’s happening.
A
new paper, published Wednesday in the Geological Society of America’s
bulletin GSA Today, includes an updated map of the Louisiana
coastline and the rate at which it’s sinking into the sea, a
process scientists call “subsidence,” which occurs in addition to
the climate change-caused process of sea-level rise. The new map
suggests that, on average, the Louisiana coast is sinking at a rate
of about 9 millimeters, or just over a third of an inch, per year —
a faster rate than previous studies have suggested, according to the
authors.
Temperature
changes around the globe are pushing human pathogens of all kinds
into unexpected new areas, raising many new risks for people.
The
grasslands of U.S. Great Plains have seen one of the sharpest
increases in large and dangerous wildfires in the past three decades,
with their numbers more than tripling between 1985 and 2014,
according to new research.
The
new study, published in the journal Geophysical Research Letters,
found that the average number of large Great Plains wildfires each
year grew from about 33 to 117 over that time period, even as the
area of land burned in these wildfires increased by 400 percent.
A
dangerously intense heat wave will grip the Southwest U.S. this
weekend and may persist through next week. The NWS has already
plastered much of the region with excessive heat warnings. A strong
ridge of high pressure, expected to rank among the Southwest's
hottest on record at upper levels, will pave the way for this
prolonged heat wave. The all-time hottest surface temperature records
for Las Vegas, Phoenix, Tucson and Needles may be challenged, as
temperatures soar to 115° - 125° Sunday through Thursday next week.
The most intense heat is expected Monday through Wednesday, with 120°
predicted by Weather Underground for Phoenix on Tuesday. Extreme heat
will also extend northwest across the highly populated Central Valley
of California.
According
to wunderground weather historian Christopher C. Burt, Phoenix has
only reached 120° three times at its official NWS site (Sky Harbor
Airport):
122°
(June 26, 1990)
121°
(July 28, 1995)
120°
(June 25, 1990)
Scientists
have documented a recent, massive melt event on the surface of highly
vulnerable West Antarctica that, they fear, could be a harbinger of
future events as the planet continues to warm.
In
the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the
largest floating ice platform on Earth, developed a sheet of
meltwater that lasted for as long as 15 days in some places.
Antarctica
is unfreezing. In the past few months alone, researchers have
chronicled a seasonal
waterfall,
widespread networks of rivers and melt
ponds and
an iceberg the size of Delaware on the brink
of breaking away from
the thawing landscape.
A
new study published
in Nature Communications only
adds to the disturbing trend of change afoot in Antarctica.
Researchers have documented rain on a continent more known for snow
and widespread surface melt in West Antarctica last summer, one of
the most unstable parts of a continent that’s already being eaten
away by warm
waters below the ice.
Rise
in tourism and warmer climate bring house flies – and the growth of
mosses in which they can live
Antarctica’s
pristine ice-white environment is going green and facing an
unexpected threat – from the common house fly. Scientists say that
as temperatures soar in the polar region, invading plants and
insects, including the fly, pose a major conservation threat.
More
and more of these invaders, in the form of larvae or seeds, are
surviving in coastal areas around the south pole, where temperatures
have risen by more than 3C over the past three decades. Glaciers have
retreated, exposing more land which has been colonised by mosses that
have been found to be growing more quickly and thickly than ever
before – providing potential homes for invaders. The process is
particularly noticeable in the Antarctic peninsula, which has been
shown to be the region of the continent that is most vulnerable to
global warming.

Portugal
has declared three days of national mourning as the country comes to
terms with a devastating fire that swept through the center of the
nation, killing at least 62 people and injuring 59 others. This drone
footage shows the scale of the devastation:

Millions of non-native creatures known as pyrosomes are "blooming" off the coast of British Columbia and have the potential to devastate an already fragile food
chain.
Scientists
in Canada know very little about the pimply, translucent, tube-like
animals — normally found in the tropics —some of which grow to 10
metres in length.
Some
Nebraska corn fields are so flooded that farmers are posting videos
of themselves wakeboarding. The image is amusing, but the realities
of the heavy spring downpours are pummeling U.S. grain farmers with
soggy fields and threats of crop disease.
In
the past 30 days, about 40 percent of the Midwest got twice the
amount of normal rainfall, with soils saturated from Arkansas to
Ohio, according to MDA Weather Services. While spring showers usually
benefit crops, the precipitation has come fast enough to flood some
corn and rice fields and trigger quality concerns about maturing
wheat.
“OUR
planet, the human family and life in all its myriad forms on Earth
are in the throes of a water crisis,” the experts are warning.
GROWING
up in Australia, most of us probably didn’t think twice about where
our seeingly endless supply of water came from. In our young minds,
the tap never ran dry.
But
the world certainly doesn’t have the luxury to think like that.
Water
is absolutely fundamental to life, which makes the increasingly loud
warnings about water scarcity and an impending global water crisis so
concerning for world leaders.
If
current patterns of consumption continue unabated, two-thirds of the
world’s population will be facing water shortages as a daily
reality by 2025 and global policy makers are scrambling to avoid
catastrophe.
The
massive iceberg poised to break off the Larsen C Ice Shelf may be a
harbinger of a continent-wide collapse that would swamp coastal
cities around the world.
Seen
from above, the Pine Island Ice Shelf is a slow-motion train wreck.
Its buckled surface is scarred by thousands of large crevasses. Its
edges are shredded by rifts a quarter mile across. In 2015 and 2016 a
225-square-mile chunk of it broke off the end and drifted away on the
Amundsen Sea. The water there has warmed by more than a degree
Fahrenheit over the past few decades, and the rate at which ice is
melting and calving has quadrupled.
On
the Antarctic Peninsula, the warming has been far greater—nearly
five degrees on average. That’s why a Delaware-size iceberg is
poised to break off the Larsen C Ice Shelf and why smaller ice
shelves on the peninsula have long since disintegrated entirely into
the waters of the Weddell Sea. But around the Amundsen Sea, a
thousand miles to the southwest on the Pacific coast of Antarctica,
the glaciers are far larger and the stakes far higher. They affect
the entire planet.
Yeah, and water is essential to life. But drink too much and it can kill you.
