- The 45th Iditarod Trail Sled Dog Race will have its ceremonial start in Anchorage on March 4. From there, the teams will travel about 350 miles north to Fairbanks where the official race will begin on March 6 at 11 a.m. local time.
The Board of Directors of the Iditarod Trail Committee voted on Feb. 10 to move the restart location from Willow to Fairbanks, according to the Iditarod Trail Committee. This is only the third time in history that the restart has been moved to Fairbanks due to poor conditions in the Alaska Range. As in 2003 and 2015, this year's official start was moved north to Fairbanks due to insufficient snow in the mountain passes.
- Moose calves across northern New England (USA) are dying at alarming rates, and scientists believe that deadly parasites benefiting from shorter winters are the primary culprits.
Winter ticks have taken a toll on moose across Maine, New Hampshire and Vermont, killing about 70 percent of moose calves. Winter ticks attach themselves to a single moose by the tens of thousands.
The ticks may be thriving in part due to the New England ecosystem being disrupted by global climate change. The average winter temperature in Maine has climbed 4 degF between 1895 and 2015.
According to Michael Bentley, a staff entomologist for the National Pest Management Association, the winter tick benefits from a warming climate.
'In the past, snowfall and freezing temperatures in early/mid spring have curbed winter tick populations by killing a percentage of those ticks that dropped off their host,' Bentley said.
Rising air temperatures have led to shorter winters and less snowcover in the spring, allowing tick populations to climb, he added.
- Tropical Cyclone Enawo made landfall between Farahalana and Antalaha late on Tuesday morning local time as an intense tropical cyclone. Enawo packed winds over 225 km/h.
At least five people have been killed and seven injured; about 22,000 have either been left homeless or suffered property damage.
There are fears that the cyclone has destroyed vanilla crops in northeastern Madagascar, where much of the world's vanilla comes from, the Associated Press reports.
The cyclone also destroyed roads and cut off communication to the Antalaha district, which is home to 230,000 people in northeastern Madagascar.
Around 500 people of the nation's capital, Antananarivo, reportedly had to take shelter in a local sports hall as a major waste canal overflowed.
The city of Sambava was pounded by strong winds and heavy rainfall on Tuesday as Enawo made landfall. Rainfall totaled more than 300 mm, leading to flooding.
The cyclone is the strongest to strike Madagascar in 13 years. Tropical Cyclone Gafilo struck similar areas in 2004 and resulted in the deaths of 363 people.
- Powerful winds knocked out power lines and caused widespread damage across much of the Great Lakes and the Northeast USA.

- The worst drought in over half a century has hit parts of East Africa affecting more than 10 million people. Thousands of families have travelled for days across scorched scrubland from Somalia to Kenya, including barefoot children with no food or water after their crops and livestock were destroyed by drought. More than 10 million people have been affected across the Horn of Africa. Acute malnutrition has reached 37% in some parts of north east Kenya and child refugees from Somalia are dying of causes related to malnutrition either during the journey or very shortly after arrival at aid camps.
The drought has been partly caused by the El Nino weather phenomenon which has affected east and southern Africa.
- The north-eastern US states of New York, New Jersey, Pennsylvania and Virginia have declared states of emergency as a huge winter storm sweeps in, bringing heavy snow.
The US National Weather Service issued blizzard warnings from eastern Pennsylvania to south-west Maine.
Schools are closed and thousands of flights have been cancelled.
The conditions caused German Chancellor Angela Merkel to postpone a trip to Washington to meet President Trump.
With winds of up to 60 mph, the storm is causing severe disruption for commuters across many parts of the north-east, and authorities in several states are advising residents to stay off the roads.
In all, about 50 million people across the country have been warned about the severe weather.
Less snow than originally anticipated is now expected to fall in New York City, with the forecast downgraded to between 10 and 20 cm by the US National Weather Service.
More than 6,800 flights have been cancelled, tracking service FlightAware reported, with airports in New York, Washington, Boston, Baltimore and Philadelphia worst hit.
Declaring a state of emergency, New York Governor Andrew Cuomo said commuters should expect road closures, delays and cancellations.
New Jersey Governor Chris Christie also declared a state of emergency and ordered all state employees not involved in the response to stay at home.
The winter storm follows a spell of unusually mild weather in the north-eastern US, with last month being the second warmest February since record-keeping began in 1895.
- Four people were killed when a large avalanche swept away a ski group in the Austrian Alps, police say.

- Four people have been rescued from rising waters overnight as torrential thunderstorms continue to soak northern New South Wales and parts of south-east Queensland, causing flash flooding.
Emergency crews in NSW received more than 80 calls for help on Wednesday night, mainly for leaky roofs, as heavy rain drenched the north and mid-north coast regions, from Taree to Lismore.
The week started with intense thunderstorms when an upper-level low-pressure system interacted with warm, moist air flowing in from the Tasman Sea. Severe storms produced damaging winds, flooding rain and large hail in parts of Queensland and NSW.
The town of Sawtell, 500km north of Sydney, received 250 mm in the 24 hours to 9am on Thursday. Smokey Cape, 450 km north of Sydney, had its heaviest March rainfall in 43 years, recording 180 mm in the 24 hours to 9am. Port Macquarie received 166mm of rain, the heaviest in 10 years for any month.
- Sixty-seven people have been killed and thousands more forced to evacuate by intense rains which damaged 115,000 homes and destroyed more than 100 bridges in Peru's worst floods in recent memory.

The disaster - which came after a period of severe drought - has been blamed on abnormally high temperatures in the Pacific Ocean, and fuelled criticism that the country is ill-prepared for the growing challenges of climate change.
World weather news, February 2017
- In the UK Supermarket giant Tesco has rationed customers to three iceberg lettuces per visit - blaming poor growing conditions in Europe for a shortage in UK stores.
It said bad weather in Spain had caused "availability issues" but suppliers were working to resolve the problem.
Morrisons has also limited shoppers purchasing iceberg lettuces and broccoli to prevent "bulk buying".

- Intense heat building back across Sydney, Australia, late this week should cause a 121-year-old record to fall.
Temperatures are set to soar to around 38C on Friday and Saturday in Sydney with a strong area of high pressure overhead.
For a city where a high of 26.5C is more common in February, this latest blast of heat will not only put a strain on residents but will also enter history books.
Friday and Saturday could make for the 10th and 11th days this summer of highs exceeding 35C at Sydney's Observatory Hill (the city's official weather station). Never before have so many such days been registered in a summer since record-keeping began in 1859.
The current record for the most days is nine, which was originally set during the summer of 1895-96, according to data from the Bureau of Meteorology. The record was tied this summer on 31 January as the city's hottest month on record came to a close.
- Following the worst drought Bolivia has seen in more than 25 years, severe thunderstorms plagued parts of central South America last week. Whilst rainfall helped alleviate drought conditions, more than 75mm of rain fell in just a few hours across parts of Santa Cruz, Bolivia, triggering severe flash floods as water inundated the dehydrated and impermeable ground. Other regions were hammered by crippling hailstorms, leaving at least two fatalities.
- Thousands of dead bats are dropping from trees after temperatures topped 45 degrees in parts of New South Wales (Australia).
The area worst affected was Casino in the Richmond Valley region of northern New South Wales, where more than 2,000 dead flying foxes have been found.
Richmond Valley Council general manager Vaughan Macdonald said many of the dead bats were difficult to access because they were scattered along riverbanks.
He said the council was working as fast as it could to dispose of the animals, but residents should brace themselves for the stench of decay.

The Houston Chronicle reported that the storms may have been a factor in one fatal crash.
- Storm Orson has made an impact on parts of the north-east US, leaving more than a metre of snow over the past week as it underwent explosive cyclogenesis, dropping 24 mb in just 15 hours.
Prior to the birth of Storm Orson cold continental air spilled southward from Canada and collided with the warmer waters of the Gulf Stream, creating a sharp temperature gradient and fuelling the rotation of a cyclone. These events most commonly occur during winter when there is a stark temperature contrast between high and mid latitudes.
- The heatwave that engulfed southeastern Australia at the end of last week has seen heat records continue to tumble like.
On Saturday February 11, as New South Wales suffered through the heatwave's peak, temperatures soared to 47C in Richmond, 50km northwest of Sydney, while 87 fires raged across the state amid catastrophic fire conditions.
On that day, most of NSW experienced temperatures at least 12 degC above normal for this time of year. In White Cliffs, the overnight minimum was 34.2C, a new record for the state's highest observed minimum temperature.
On Friday, the average maximum temperature right across NSW hit 42.4C, beating the previous February record of 42.0C. The new record stood for all of 24 hours before it was smashed again on Saturday, as the whole state averaged 44.0C at its peak. At this time, NSW was the hottest place on Earth.
And still the records continue to fall. Mungindi, on the border of NSW and Queensland, broke the Australian record of 50 days in a row above 35C, set just four years ago at Bourke Airport, with the new record now at 52 days.
Meanwhile, two days after that sweltering Saturday we woke to find the fires ignited during the heatwave still cutting a swathe of destruction, with the small town of Uarbry, east of Dunedoo, all but burned to the ground.
- California ski resorts are experiencing a significant snowfall season, with some areas breaking records for snowfall amounts.
In the first month of the year, Squaw Valley Alpine Meadows in Olympic Valley, California, had snow totals that were 405 percent of their usual average for January. While the average January snowfall for the past 45 years sits at 70 inches, January 2017 capped out at a total of 282 inches of snow.
Resorts have had improved ski conditions and have been able to offer guests access to more terrain.
"There are areas that just haven't been skiable like they are now," said Sam Kiekhefer, a public relations coordinator for Squaw Valley Alpine Meadows.
The January 2017 record surpassed the previous record, 175 inches in January 1982, by 107 inches. The season total by the end of January was 387 inches of snow. Less than halfway through their usual 175-day season, the resort had already received 86 percent of the average for seasonal snowfall.

- New Year's Eve fireworks contributed to dangerously high levels of pollution in several German cities, official figures suggest.
In Munich, particulate levels briefly reached 26 times the EU-recommended daily limit of 50 micrograms of particulates per cubic metre of air.
National figures suggest that firework displays ejected some 4,000 tonnes of particulates into the atmosphere.
That reportedly equates to 15% of yearly vehicle particulate emissions.
Airborne sooty particulates are mostly emitted during the burning of fossil fuels and contribute to deaths from respiratory illnesses.
The German figures have prompted environmentalists to call for restrictions on the sale of private fireworks.
- A thick fog settled over large parts of China, including the capital of Beijing, early in the week prompting hundreds of flight cancellations across the country. The dense fog also forced highways to be shut down with visibility being reduced to just a few hundred feet.

- Provisional full-year figures for global average near-surface temperatures confirm that last year, 2016, was one of the warmest two years on record, nominally exceeding the record temperature of 2015.
When viewed alongside 2015, the two years are the warmest in an annual series of figures that starts in 1850.
Scientists at the Met Office Hadley Centre and the University of East Anglia's Climatic Research Unit produce the HadCRUT4 dataset, which is used to estimate global temperature. The global temperature series shows that 2016 was 0.77+/-0.1 degC above the long-term (1961-1990) average, nominally a record since at least 1850. When compared with the 1850 to 1900 baseline - which is indicative of pre-industrial temperatures - the 2016 average global temperature anomaly was around 1.1 degC. For comparison, 2015 was 0.76+/-0.1 degC above the long-term (1961-1990) average.
- The number of devastating floods that trigger insurance payouts has more than doubled in Europe since 1980, according to new research by Munich Re, the world's largest reinsurance company.
The firm's latest data shows there were 30 flood events requiring insurance payouts in Europe last year - up from just 12 in 1980.
Globally, 2016 saw 384 flood disasters, compared with 58 in 1980, although the greater proportional increase probably reflects poorer flood protections and lower building standards in the developing world
Ernst Rauch, the head of Munich Re's corporate climate centre, said:
"Flood events together with wind storm events are the two perils where
we have the biggest increase in frequency worldwide."
- A powerful 'weather bomb' has hit New Zealand, cutting off rural towns, flooding major roads and dumping snow on to bare alpine ski fields at what should be the height of the southern hemisphere summer.
The significant low edged over the South Island late on Thursday afternoon, causing landslips and snow, and went on to lash the country throughout the weekend.
Auckland in the North Island suffered major power outages, while rivers on the west coast of the South Island rose rapidly in a matter of hours, lapping at road-sides and carrying large debris, including trees washed down from the Southern Alps.
A landslip also buried the famous Sylvia Flats hot pools, and residents of Dunedin reported having to burn their fences to stay warm after being caught off guard by the unseasonal weather.
'This weather bomb was caused by a burst of really hot air coming out of Australia and forming a low when it moved into the Tasman Sea, and then picking up moisture and increasing in intensity,' said Mads Naeraa-Spiers, a forecaster for the MetService.
- Deadly weather in the south-eastern US has left at least 18 people dead and injured dozens more as residents along the Georgia-Florida line braced for more intense, fast-moving storms including unusually strong -long track tornadoes.
On Sunday, a tornado blew through a mobile home park in rural Cook County in southern Georgia, sheering off siding, upending homes and killing seven people, officials said.
Coroner Tim Purvis said an apparent tornado 'leveled' the park before dawn and that emergency responders searched for survivors for hours. Purvis said the park had about 40 mobile homes and roughly half were destroyed.
Four people were killed in adjoining counties on Sunday and another three were confirmed on Sunday evening in Dougherty county where Albany is located, said Catherine Howden, spokeswoman for the Georgia Emergency Management. A further four were killed in Mississippi by a tornado on Saturday making a total of 18 fatalities.
The weather service's Storm Prediction Center warned on its website of a 'dangerous outbreak of tornadoes' on Sunday afternoon and pressed for residents to prepare.
There were 4.8 million people under the high risk area; the total in the area of bad weather in the south east, who came under the slight risk category or worse, was about 38 million people.
While the central part of the US has a fairly defined tornado season - the spring - the risk of tornadoes 'never really goes to zero' for most of the year in the south east, said Patrick Marsh, warning coordination meteorologist at the Storm Prediction Center in Norman, Oklahoma.
- Northern Territory aircraft are struggling to deliver food to flood-affected remote communities as torrential rains are luring swarms of insects into central Australian outback towns.
Several Indigenous communities west of Alice Springs, including Kintore, Kiwirrkurra, Willowra and Nyirripi, have been cut off by heavy rainfall and need food supplies to be flown in.
But some dirt airstrips in the region have become too wet to land safely and conditions in Alice Springs are too dismal for takeoff. "We can't see the mountain ranges at all today, we're going to have to delay flights out of here," Chartair's Robyn Lelliott said.
"Kiwirrkurra is one of the most isolated communities in the world - they are so reliant on our services. The next couple of days are not looking good for flying."
Katherine has been cut off and the deluge has caused a goldmine north of the town to release contaminated water, with the nearby Edith river flowing at a high enough rate to dilute it. A minor flood warning is now in place for the Katherine Gorge. Several Arnhem Land communities are now islands.
Meanwhile, thousands of grasshoppers have descended on Alice Springs and the surrounding desert region after the recent storms.
- Dramatic TV footage has captured the moment a three-storey hotel collapsed into a swollen river in Peru.
Dating from colonial times, La Hacienda was located near the bank of the river Sicra in the town of Lircay.
Heavy rains began in the area on Wednesday and continued for 10 hours, eroding the river edge and then the building's foundations. The 50-room hotel was evacuated as the situation worsened and nobody was injured when the hotel finally crashed into the fast-flowing torrent.
Other buildings in the town in Peru's Huancavelica region were also destroyed or damaged as a result of the constant heavy rain.
Roads have also been blocked by landslides.
- There are fire bans across the Australia's south-east, with Victoria, New South Wales and the ACT all heading for sweltering temperatures in the high 30s and even 40s (Celsius).
In NSW, the Bureau of Meteorology issued a fire warning for much of the state's south and the far western region, with the Rural Fire Service declaring a total fire ban for those areas.
The town of Moree in northern NSW was set for its 33rd day in a row over 35C.
The city broke the previous state record for the most days in a row over 35C - 17 - about two weeks ago, and is expected to continue to break its own record for at least the rest of the week.
