Zombie Fires In the Arctic and Brazil’s Big Burn

The World Resources Institute reported this week that nearly 30 million acres of forest were destroyed globally in 2019, an increase of 3% over 2018, with the heaviest losses in the tropics.  How much forest is that?  It’s a football field every 6 seconds.  Brazil led the world (by a huge margin) due to the major fires in the Amazon.  And because of the particularly warm spring in the Arctic, scientists are now seeing “zombie” fires across the region which are remnants of the record blazes that occurred there last year.

Why This Matters:  Our best natural defense against climate change is holding on to mature forests — and it is also one of the key ways to defend against pandemics.  Deforestation is literally killing us and the planet.   Humans are the main culprits of tree loss — according to the report, deforestation for commercial purposes, such as timber, farming, and mining was a greater source of the decline than climate-related fires. And in the Arctic, firest are literally popping up again from within the soil where they had been hibernating — which does not bode well for this summer.

Forest Loss

The World Resources Report also expresses concern about forest loss in 2020 due to the coronavirus pandemic due to a lack of enforcement of rules against deforestation and a higher incidence of illegal logging and fires. In addition, due to the global economic downturn, some countries may attempt to re-start their economies with extractive industries, as was the case in Indonesia during the Asian Financial Crisis.  2019’s forest loss number was the third highest in the last 20 years.  If the trees had remained standing, it would have been the equivalent of taking 400 million cars off the road.

Arctic Fires

2019 was a record year for forest fires in the Arctic — and scientists suspect the current fires, which have been seen on satellite imagery, are “zombie” fires because they are in the same places as last year.  Zombie or “holdover” fires are those that continue to burn underground and then reignite on the surface after a period of time — sometimes many months or even years later. Since 2005, there have been 39 zombie firest identified in Alaska alone.

What’s to Blame for CA Fires, Forest Management or Climate Change?

As wildfires across the West continue to rage, President Trump has continued to push the message that the cause of the fires is solely due to poor forest management. It’s not a new message for Republicans, but science unequivocally points to the ways in which climate change is supercharging wildfires. Ezra Romero, an environmental reporter […]

Deforestation in Afghanistan Multiplies Climate and Security Threats

by Julia Fine, ODP Contributing Writer As Stefanie Glinski reported for the Thomson Reuters Foundation this week, large-scale deforestation in Afghanistan, due primarily to the past 40 years of war, has advanced flooding in the country (as trees prevent soil erosion and serve as a buffer against flooding). According to Glinski, “Trees have long been […]

Trump Administration Proposes Another Timber Sale in Alaska’s Tongass

After its first proposed sale was blocked by a federal judge, the Trump Administration proposed on Friday a second timber sale in the pristine Tongass National Forest in Alaska, The Hill reported.  The sale would cover 6000 acres, including 5000 acres of old-growth trees and the proposal also includes road-building activities.

Why This Matters:  The Tongass is the largest national forest and one of the most important forests in the world (as the Ag Department itself says – watch the video) because it contains some of the last surviving old-growth temperate rainforests in North America and is home to numerous species of endangered wildlife and is very important to several native tribes.
