"Dante's Inferno" in Chile: All-Time National Heat Record Smashed by 6°F

https://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3548

Extract:

Record heat and extreme drought in Chile are contributing to their worst wildfires in decades. On Thursday, the entire town of Santa Olga was destroyed by fire, with more than 1,000 building consumed including schools, nurseries, shops and a post office.

Australia heatwave: Unprecedented fire conditions are 'as bad as it gets'
NSW is facing the "worst possible fire conditions" in its history with a "catastrophic" warning in place across large slabs of the state after a heatwave smashed temperature records on Saturday.

Rural Fire Service (RFS) Commissioner Shane Fitzsimmons said the situation was as "bad as it gets" and warned it was set to get worse on Sunday when winds are expected to sweep through scorched parts of mid to northern NSW.
...
Commissioner Fitzsimmons said conditions in some parts of NSW could be worse than Victoria's Black Saturday fires, Australia's worst ever fire disaster which claimed 173 lives in 2009....

Wildfires have charred a whopping 2 million acres across the U.S. so far this year, an area larger than the state of Delaware.

It's a gigantic number for so early in the season, roughly 10 times the average and also the most acres burned as of mid-March since 2006, according to spokeswoman Jessica Gardetto of the National Interagency Fire Center in Boise, Idaho.

Many of the blazes have been massive grass fires in Oklahoma and Kansas, which have both set records for number of acres burned in March, Gardetto said....

Destructive and Deadly U.S. Wildfires Have Burned More Than Four Times the Average So Far in 2017
Wildfires have charred more than four times the average acreage to date in what has been a destructive and deadly start to 2017 in the United States.

Almost 2.2 million acres had been burned by 14,529 wildfires as of April 7, the National Interagency Fire Center (NIFC) reports. The area of land burned so far in 2017 dwarfs the 10-year average (2007-2016) of 434,696 acres for this point in the year, but the actual number of fires is close to the average of 13,731.

Southeast U.S.:  West Mims Fire burning in the Okefenokee National Wildlife Refuge near the Florida-Georgia border has now burned nearly 144,000 acres (58,275 hectares).

Dry pattern to offer no wildfire relief as West Mims Fire evacuations expand
As crews continue to battle the massive West Mims Fire, mainly dry weather will worsen the wildfire and drought situation across the Southeast into late May.

Severe to extreme drought conditions from southern Georgia through the Florida Peninsula has left the region a tinderbox since the beginning of the year.

The largest active fire in the region is the West Mims Fire burning in the Okefenokee National Wildlife Refuge near the Florida-Georgia border.

The blaze, which is only 12 percent contained, has grown exponentially to over 140,000 acres since being sparked by a lightning strike on April 6, according to InciWeb.

Mandatory evacuations were expanded on Tuesday to encompass the entire southern half of Charlton County, Georgia. ...

I don't want to say it with certainty, but I suspect this is being exacerbated by compounding year over year losses of permafrost. Winter doesn't help the situation either, with snowfall anomalies wayyyyyy above normal insulating the ground from cooling off, while every subsequent summer allows more heat to accumulate.

According to the Florida Forest Service, there were 125 active wildfires burning across the state on lands under its jurisdiction as of 7:30 a.m. [May 8]. The fires affected an estimated 31,154 acres. Twenty-seven of those fires, including Pasco’s Anclote Branch blaze, were deemed major, spanning 100 acres or more. State officials also reported there were four fires burning on federal lands in Florida. Those blazes span some 153,746 acres....

The linked article indicates that fire could transform the Amazon forests this century

Le Page, Y., Morton, D., Corinne, H., Ben, B.-L., Cardoso Pereira, J. M., Hurtt, G., and Asrar, G.: Synergy between land use and climate change increases future fire risk in Amazon forests, Earth Syst. Dynam. Discuss., https://doi.org/10.5194/esd-2017-55, in review, 2017.

http://www.earth-syst-dynam-discuss.net/esd-2017-55/

Abstract. Tropical forests have been a permanent feature of the Amazon basin for at least 55 million years, yet climate change and land use threaten the forest's future over the next century. Understory forest fires, common under current climate in frontier forests, may accelerate Amazon forest losses from climate-driven dieback and deforestation. Far from land use frontiers, scarce fire ignitions and high moisture levels preclude significant burning, yet projected climate and land use changes may increase fire activity in these remote regions. Here, we used a fire model specifically parameterized for Amazon understory fires to examine the interactions between anthropogenic activities and climate under current and projected conditions. In a scenario of low mitigation efforts with substantial land use expansion and climate change – the representative concentration pathway (RCP) 8.5 – projected understory fires increase in frequency and duration, burning 4–28 times more forest in 2080–2100 than during 1990–2010. In contrast, active climate mitigation and land use contraction in RCP4.5 constrain the projected increase in fire activity to 0.9–5.4 times contemporary burned area. Importantly, if climate mitigation is not successful, land use contraction alone is very effective under low to moderate climate change, but does little to reduce fire activity under the most severe climate projections. These results underscore the potential for a fire-driven transformation of Amazon forests if recent regional policies for forest conservation are not paired with global efforts to mitigate climate change.

Huge forest fires in Portugal kill more than 60 people

https://www.theguardian.com/world/2017/jun/18/portugal-more-than-20-people-killed-in-forest-fires

At least 62 people have been killed in huge forest fires in central Portugal, many dying in their cars as they tried to flee the flames.

Portugal’s prime minister, António Costa, described the blazes – which have injured dozens more people – as “the greatest tragedy we have seen in recent years in terms of forest fires”, and warned the death toll could rise. Three days of national mouring were declared.

The linked article is entitled: "These NASA Images Show Siberia Burning Up"; and with continued global warming, these wildfires are expected to continue to increase in frequency & extent:

http://www.climatecentral.org/news/nasa-siberia-wildfires-21576

Extract: "Siberian wildfire season is off and running with multiple blazes searing the boreal forest and tundra. It’s the latest example of the vast shifts happening to the forests that cover Siberia and the rest of the northern tier of the world as climate change alters the landscape.

Those forests are burning at a rate unheard of in at least 10,000 years due largely to rising temperatures. They contain vast reserves of carbon stored in trees and soil and when they burn, they send that carbon into the atmosphere. That creates a dangerous cycle of more severe wildfires and ever rising temperatures."

https://robertscribbler.com/2017/07/16/echoes-of-fort-mcmurray-massive-canadian-wildfire-forces-the-emptying-of-another-canadian-city/

Extract: :"A little more than a year after a massive wildfire forced the full evacuation of Fort McMurray in Alberta, another set of extreme wildfires in British Columbia is again forcing major population centers to empty. In the region of Williams Lake and Cariboo City, 17,400 people have been forced to flee as a wildfire is threatening the major highway exiting the area. As the fire expands, another 27,000 in the broader province may also be asked to leave. This mass evacuation has been enough to empty large urban centers — turning them into ghost towns as fires rage through the surrounding countryside."

The linked reference, indicates that an increase in weather induced lighting strikes has driven major North American boreal forest fires:

Sander Veraverbeke, et. al. (2017), "Lightning as a major driver of recent large fire years in North American boreal forests", Nature Climate Change, 7, 529–534doi:10.1038/nclimate3329

http://www.nature.com/nclimate/journal/v7/n7/full/nclimate3329.html

Abstract: "Changes in climate and fire regimes are transforming the boreal forest, the world’s largest biome. Boreal North America recently experienced two years with large burned area: 2014 in the Northwest Territories and 2015 in Alaska. Here we use climate, lightning, fire and vegetation data sets to assess the mechanisms contributing to large fire years. We find that lightning ignitions have increased since 1975, and that the 2014 and 2015 events coincided with a record number of lightning ignitions and exceptionally high levels of burning near the northern treeline. Lightning ignition explained more than 55% of the interannual variability in burned area, and was correlated with temperature and precipitation, which are projected to increase by mid-century. The analysis shows that lightning drives interannual and long-term ignition and burned area dynamics in boreal North America, and implies future ignition increases may increase carbon loss while accelerating the northward expansion of boreal forest."

More than 45,000 people displaced by B.C. wildfires

Evacuations prompted by wildfires in central B.C. are approaching record levels for the province, officials said Tuesday.

The total number of people displaced by the fires is now estimated at 45,806, according to Robert Turner, deputy minister for Emergency Management B.C.

"This number has changed fairly significantly in the past 48 hours and that has to do primarily with getting better information from local governments," Turner said.

"It's becoming one of the largest displacement events in the history of the province."

How Weeks of Downpours Sparked Wildfires in California
- Precipitation from the drought-busting winter has fueled fires
- Grass that greened valleys, hillsides, now is fuel to burn
Some 2,905 fires started between Jan. 1 and July 9, burning more than 68,129 acres on state and local lands, more than double the five-year average of 27,390 acres and the 30,574 that burned by the same date last year. When you throw in areas maintained by the U.S. Forest Service, the total acreage aflame or scorched across the state rises to 92,439 acres. Governor Jerry Brown declared an emergency in Santa Barbara County where two fires have forced people from their homes, threatened agriculture and could even sever major power lines and drive up electricity prices.

Transmission lines are ubiquitous in California, seemingly rising and falling over almost every hill. When one of those lines is cut, the supply is separated from its demand -- like last Thursday, when 1,000 megawatts of electricity coming in from Oregon were cut off from customers in California by a fire burning near the state line, said David Quinn, a power-market analyst specializing in California at Genscape Inc. in Boston. Or sometimes, Quinn said, power will be traveling from the southern part of the state to customers in the north when a fire interrupts the line. That’ll cause electricity prices at the destination to surge while the south finds itself awash in excess electricity.

Summer fires in California aren’t anything new, of course. Around this time of year the West in general tends to start burning, said Robyn Heffernan, a National Weather Service fire weather science meteorologist in Boise, Idaho.

What is new is that the numbers and intensity of fires seem to be rising, a consequence of climate change, Head said.

“They are much longer-burning, much hotter and much faster-spreading,” she said. “There are parts of California that don’t go out of fire season.”
