The Australian bureau of meteorology
was forced to add a new color to their weather map because of astonishing heat.
Purple was placed on the map to represent the head of 129.2 degrees Fahrenheit,
or 54 degrees Celsius. "The scale has just been increased today and I
would anticipate it is because the forecast coming from the bureau's model is
showing temperatures in excess of 50 degrees," said David Jones, head of
the bureau's climate monitoring and prediction unit. This heat also comes with
a high risk of fire, which has already struck. Australian officials are
labeling these risks and threats as “catastrophic”

Up to half of all food produced is wasted
The Institution of Mechanical
Engineers reported that anywhere between 1.2 and 2 billion tons of food is
wasted each year, which means that it is possible that half of the food produced
on this planet is wasted. “Due to poor practices in harvesting, storage and
transportation, as well as market and consumer wastage, it is estimated that 30–50% of all food produced never reaches a
human stomach” the institute reports. The major cause of this wastage is inadequate
engineering and agricultural knowledge, another is the demand from supermarkets
for always perfect produce, causing much produce to be thrown away, and their
influencing customers to buy more food than is needed.
Under Construction: The World's Largest Thermal Solar Plant
In the middle of the Mojave Desert
there is a massive concentrated solar thermal power plant being built, and if
everything goes successfully, will be the largest in the world. The plan for
this power plant is to have 300,000 mirrors directing the sun’s energy toward
three towers, which will create 392 megawatts of electricity, which is enough
electricity to power 140,000 U.S. homes.
The complication is that even though solar power is cleaner and a more
sustainable energy to say coal, creating a power plant of this scale will
forever alter the natural environment.
New material harvests energy from water vapor
MIT
engineers have created a new polymer film that generated electricity by absorbing
water vapor. The film absorbs tiny amounts of water vapor allowing it to curl
up and own, and if we harness this continuous motion, we could drive robotic
limbs or generate enough electricity to power micro- and nonelectric devices. “With
a sensor powered by a battery, you have to replace it periodically. If you have
this device, you can harvest energy from the environment so you don't have to
replace it very often,” says Mingming Ma, a postdoc at MIT’s David H. Koch
Institute for Integrative Cancer Research. Mingming is also the lead author of
a paper describing this new material.
Beijing air pollution soars to hazard level
Last Saturday
and Sunday the residents of Beijing have refused to step outdoors in fear of
the air pollution. The air pollution recorded was 30-45 times the safety level.
The average concentrations of the tiniest pollution particles, called PM2.5,
should be no more than 25 micrograms per cubic meters, at 300, children and
elderly should stay indoors. Official Beijing city reading recorded pollution
levels of over 400, unofficial recordings from the U.S embassy recorded 800.
Two of the major pollutants are the coal dust and car fumes. Heavy smog has smothered
Beijing for many days said one of the news reporters.
Sea level rise of more than 3 feet plausible by 2100
Melting glaciers in Antarctica and
Greenland may cause sea levels to rise by more than 3 feet by the end of this century.
This rise in sea level would force millions of people in low-lying countries
such as Bangladesh, swamp atolls in the Pacific Ocean, cause dikes in Holland
to fail, and cost coastal mega-cities from New York to Tokyo billions of
dollars for construction of sea walls and other tools to stop the tides from
coming in. Although there is only a 5% chance of this occurring, it is still a
very bad situation. The other 95% is estimated at the sea level rising about 1
foot.
