Canadian Fire Season Starts Far too Early as Fort St. John Residents are Forced to Flee the Flames

Fires can be beneficial by removing ladder fuels, but they are not a valuable maintenance force in the deserts I frequent. Here, fire is destructive and recovery requires decades to a century. Rising temperature and drought will make recovery slower. It’s been so dry lately that the introduced invasive species haven’t produced much fine fuel this year, and though the cause is suspect, the outcome might be good.

It’s been a ridiculously hot Winter and Spring for most of Western and Northern Canada. And in many locations, odd, Summer-like conditions are already starting to dominate. For these regions — areas sitting on piles of dry vegetation or thawing permafrost — a single hot day, thunderstorm, or even just the melting away of the Winter snow is now enough to spur the eruption of wildfires.

In Fort St. John, along the shores of Charlie Lake in Northeastern British Columbia and at about the same Latitude line as Ft. McMurray in Alberta, temperatures on Monday rocketed to 28 degrees Celsius (about 82 degrees Fahrenheit). These scorching readings were about 20 degrees C (36 degrees F) above average for the day. The excessive early-season heat sweltered an area that had seen extensive drying throughout a long, warm winter. And nearby grasses and crops became a ready fuel as Monday’s…

Earth Day checklist: five simple things you can do to make a difference

Celebrating Earth Day on 22 April is nice, but is one day truly enough? Madeleine Somerville describes five small lifestyle shifts that will make a big impact.  From: www.theguardian.com

Can you put a price on nature? A Californian nonprofit thinks it can

“Everyone agrees that nature has value. It clothes, feeds and shelters us – and provides a spectacular playground. Yet we have never put a value on everything nature offers.

“Now, environmental and sustainable business consultants want to change that by forcing corporate leaders to take stock of the economic impact of how they manage natural resources. By accounting for this so-called natural capital, the advocates hope to see more businesses adopting practices that are both good for the environment and long term profitability, especially as climate change will further deplete natural resources, causing their values to climb and increase the cost of running business. In a 1997 paper in Nature that first introduced the natural capital concept, the 13 researchers involved pegged the Earth’s worth at $33tn. A 2014 revision raised that figure to $134tn.”  From: www.theguardian.com

GR:  Natural ecosystems are the outcome of hundreds and thousands of years of trial and failure. The high cost of replicating the process and thus the high value of nature will not make many businesses happy.  Perhaps “natural” is a standard too high.  Unfortunately, so many attempts to create man-made versions of nature have failed; natural may be the only goal that is reasonable.

Clinton-Sanders fracking fracas heats up

“Their feud is exposing a rift among Democrats that could haunt Clinton beyond the party’s convention in July.”  From: www.politico.com

This Is Why the Great Barrier Reef Is Dying

“The Great Barrier Reef is one of the most celebrated ecosystems on Earth—and it’s dying. Months of extreme heat have turned thousands of miles of pristine habitat into an endless watery graveyard. This year’s coral bleaching event comes as a warning.”  From: gizmodo.com

With citizen science, people take research into their own hands

“From CNET Magazine: Around the world, regular people with no formal training are contributing to some of today’s most exciting scientific research. You can join them.”  From: www.cnet.com

GR:  We sometimes refer to volunters as citizen naturalists as well as citizen scientists.  There are many ways to join.  Check with the Citizen Science Association (https://garryrogers.com/2015/01/17/new-journal-citizen-science) for more information.

Better land use one of the keys to slowing global warming

Soil Erosion--3GR: Carbon storage in soils equates to fertility. Over most of the Earth’s land surfaces, grazing and farming lead to loss of topsoil, the upper soil layer that holds the carbon. It will be very difficult to improve the current wasteful practices since the growing human population is urgently demanding more meat and potatoes. Unlike disaster movies with a positive conclusion, our waste of the soil will lead to a bad ending. Unlike the alien invaders in the movie Independence Day, we humans cannot move on when our resources are exhausted.

Study quantifies climate benefits of sustainable land use

Staff Report

Switching to more sustainable forms of land use management could significantly boost the carbon-storing capacity of the planet’s soils — by up to 8 billion tons of greenhouse gases, scientists reported in a new study. Previous research shows that soils currently lock away around 2.4 trillion tonnes of greenhouse gases, which are stored underground as stable organic matter.

The measures identified by the researchers include growing crops with deeper root systems and using charcoal-based composts. Widespread adoption sustainable land use practices and and application of best available technologies could help soils store up to 80 percent of greenhouse gases released by fossil fuel combustion, the researchers calculated.

Fossil Fuel and Nuclear Industries in lockstep in Australia – theme for April 16

Heads in sand.

Christina Macpherson's avatarAntinuclear

coal and nuclear AustraliaDespite the global imperative and a strong public movement to reduce greenhouse gas emissions, Australia’s coal, gas and oil industries predict a prosperous future for decades to come.

The nuclear industry proudly touts itself as the solution to climate change. But nothing could be further from the truth.  The full nuclear fuel chain emits large amounts of Co2 and other greenhouse emissions. In the coming decades, indirect carbon dioxide emissions from nuclear power plants will increase considerably, because high-grade resources of uranium are exhausted and much more fossil energy will have to be used to mine uranium. In view of this trend, nuclear power plants will no longer have an emissions advantage over modern gas-fired power plants, let alone in comparison to the advantages offered by increased energy efficiency or greater use of renewable energies.

Even when they pretend that nuclear power would cut emissions, the industry itself is well…
