It's Science Week

to look through old ships' log books and track weather observations from the 1890s and 1900s. It's a good project for older kids, and aims to improve weather forecasting and track climate change. Do try this at home, kids.

Since January there have been signs of a possible El Niño brewing in the pacific, the first major one since 1998. While the US-funded ocean-monitoring system is in a state of partial collapse
, the data has continued to grow stronger, and this may now be the largest ocean temperature anomoly ever seen
. A major El Niño could significantly boost global temperatures, cause severe weather and storms, melt Arctic sea ice and help push the world into a warm phase of the Pacific Decadal Oscillation, accelerating global warming. (more discussion

On June 11th, 2013, in the wee hours of an early summer night in Nebraska, the temperature shot from 73°F to 99°F in the space of minutes
, accompanied by 50MPH winds. The cause of this weather oddity was the poorly understood Heat Burst
, a phenomenon that sometimes occurs as thunderstorms die out
, usually late at night. The temprature rise can be so extreme that it has been imaged from space
, and there are unconfirmed stories
of heat so extreme that crops were cooked in the fields where they grew, and paint blistered on houses and vehicles. Once believed to be a very rare
event, with the advent of personal weather stations, science may find they are more frequent than was previously believed.

On January 4th, 2013, in the midst of a national heat wave
, Tasmania experienced some of the most extreme weather on record, with Hobart recording a record temperature of 41.8°C in the afternoon. Fires blazed around the state, covering almost 50,000 acres, claiming hundreds of properties, and destroying the town of Dunalley. The Tasman peninsula was cut off by the fires, necessitating a sea rescue of over 2,000 people. An image of a family clinging to a jetty in the water
to escape from the fire captured the attention of the world. With the launch of their Australian edition, The Guardian have produced a frightening and fascinating multimedia article

What won the war? The weather helped. For while the Allies had access to all the Atlantic meteorology, the Axis couldn't easily predict what systems were rolling in from the West - and with the Battle of the Atlantic the one thing
that Churchill said kept him awake at night, knowing which way the wind blew certainly needed a weatherman. Or Britain would never be starved into submission.

Spring Rain, Then Foul Algae in Ailing Lake Erie: [New York Times]
"A thick and growing coat of toxic algae appears each summer, so vast that in 2011 it covered a sixth of its waters, contributing to an expanding dead zone on its bottom, reducing fish populations, fouling beaches and crippling a tourism industry that generates more than $10 billion in revenue annually."
Chicago has been having some fairly remarkable weather lately, even by their standards. On the 25th of January there was more than an inch of snowfall recorded for the first time in 335 days
, a new record. Then a surge of warm air
from the south brought a temperature of 63 degrees at O'Hare airport on January 29th
, a new record for that date, exactly one week after a temperature of 9 degrees was recorded
(which, combined with the 35mph winds on that date, produced a windchill factor of about -20f). The current forecast (at time of posting this)
calls for a high of only 14f on Friday (Feb. 1st), another significant temperature swing within a few days.
...and the news ain't good: "Evidence for climate change abounds, from the top of the atmosphere to the depths of the oceans. This evidence has been compiled by scientists and engineers from around the world, using satellites, weather balloons, thermometers, buoys, and other observing systems. The sum total of this evidence tells an unambiguous story: the planet is warming."

Meteorologist and climatologist Barbara Mayes Boustead has loved the Little House books since she was a little girl
. At her blog Wilder Weather, Barbara makes "connections between weather and climate concepts, events during Laura’s time and in her books, and present or future weather and climate concerns
." For example, in October of 1880, a storm is brewing.
"The initial shot of cold air brought near-freezing temperatures and a little bit of precipitation up north on the 14th. The low pressure system deepened on the 15th as it got spinning in eastern Nebraska, pulling cold air around behind it while it brought moisture up from the south. Then, the low pressure just sat there for a while and deepened. As it got deeper, the winds behind it – in eastern South Dakota – got stronger. The storm stayed in the area of northwest Iowa to southern Minnesota
through the 16th, then pulled away into northern Michigan on the 17th, leaving cold air and breezy conditions behind it." And in De Smet, South Dakota, Laura Ingalls and her family settle in for the beginning of the Long Winter
