destroying the planet, a bit less in these covid-affected times...

overshoot

OAKLAND, CA, USA — JUNE 5, 2020 — Earth Overshoot Day 2020 lands on August 22, more than three weeks later than in 2019, according to Global Footprint Network.


The date reflects the 9.3% reduction of humanity’s Ecological Footprint from January 1st to Earth Overshoot Day compared to the same period last year, which is a direct consequence of the coronavirus-induced lockdowns around the world. Decreases in wood harvest and CO2 emissions from fossil fuel combustion are the major drivers behind the historic shift in the long-term growth of humanity’s Ecological Footprint.


The sudden year-over-year Ecological Footprint contraction, however, is a far cry from the intentional change which is required to achieve both ecological balance and people’s well-being, two inextricable components of sustainability. At Global Footprint Network, we envision a world where humanity lives on our planet’s ecological budget by design rather than by disaster, so that all thrive within the means of Earth.


“Humanity has been united by the common experience of the pandemic and shown how intertwined our lives are. At the same time, we cannot ignore the deep unevenness of our experiences nor the social, economic, and political tensions which have been exacerbated by this global disaster,” said Global Footprint Network CEO Laurel Hanscom. “Making regeneration central to our rebuilding and recovery efforts has the potential to address the imbalances both in human society and in our relationship with the Earth.”


....


Each year, Earth Overshoot Day marks the date when humanity has used all the biological resources that Earth can renew during the entire year. Humanity currently uses 60% more than what can be renewed – or as much as if we lived on 1.6 planet. From Earth Overshoot Day until the end of the year, humanity grows the ecological deficit which has been increasing steadily since the world fell in ecological overshoot in the early 1970s, according to the National Footprint & Biocapacity Accounts (NFA) based on UN datasets (with 15,000 data points per country per year). Since UN data only stretches to 2016, the global results for 2020 have been assessed using complementary data.


To determine the impact of the pandemic on the carbon Footprint (14.5% decrease), the period from January 1st to Earth Overshoot Day was divided into three segments: January-March, for which the International Energy Agency (IEA) released an analysis of energy and emissions reductions; April-May, when the most restrictive lockdowns occurred; and June-Earth Overshoot Day, during which the gradual loosening of confinement policies is expected.


Lessons carrying us forward


This year more than ever, Earth Overshoot Day provides an unprecedented opportunity to reflect on the future we want. Efforts to respond to COVID-19 have demonstrated that shifting ecological resource consumption trends in a short timeframe is possible. As we emerge out of the public health crisis and focus on rebuilding our economies and our lives, strategies informed by biological resource security and 1-planet prosperity are far more likely to bring about the positive outcomes that decision makers seek.


Already, powerful lessons can be drawn from the collective experience of the pandemic:


Governments are capable of acting swiftly, both in terms of regulations and spending, when they put human lives above all else;

Humanity is one biology and is stronger when we act together:

Businesses – including our partner Schneider Electric – and individuals alike can effectively align and collaborate in the pursuit of a shared goal when people recognize that their own lives, and that of the people they love, may be at risk.

The necessary actions required to protect oneself, one’s household, and one’s community also protect others; one’s decisions at all levels have consequences for all.

By now, we have witnessed what is possible when humanity comes together to pursue a shared outcome. What shared outcome could be more important than our long-term success on our finite planet?

the climate is still warming though...

In addition to a change in climate and wildlife, the melting ice may have geopolitical consequences as lucrative shipping routes in the Arctic become ice-free, Danish researchers have warned.

The Arctic sea ice is melting faster than climate models predicted, researchers at the University of Copenhagen and the Danish Meteorological Institute have warned.

Unlike previous climate models that forecast a slow and steady rise in Arctic temperatures, the new study shows the warming is occurring at a more rapid pace.

“We have been clearly underestimating the rate of temperature increases in the atmosphere nearest to the sea level, which has ultimately caused sea ice to disappear faster than we had anticipated”, University of Copenhagen professor Jens Hesselbjerg Christensen said in a statement.

Their findings suggest that the unusually high temperatures currently being seen in the Arctic Ocean were only observed during the previous Ice Age. At that time – between 120,000 and 11,000 years ago – the area around Greenland experienced a series of violent and sudden climate fluctuations, where the temperature rose several times by up to 10-12 degrees over short spans of 100-200 years, after which it dropped again.

According to their analysis, air temperature near the surface of the Arctic Ocean has risen by an average of as much as one degree per decade over the last 40 years. In some areas it has risen by almost two degrees.

“So we are talking almost eight degrees in 40 years in some places. It goes far, far faster with the temperature rises than we have calculated in most of our models”, Jens Hesselbjerg Christensen stressed in an interview with Danish Radio. “Changes are occurring so rapidly during the summer months that sea ice is likely to disappear faster than most climate models have ever predicted”, Hesselbjerg Christensen stressed.

Seen with today's optics, this could mean that the summertime sea ice may disappear completely quite soon, maybe by the 2030s, the researchers warned.

And as if that were not enough, the warming is further amplified the faster the ice shrinks, a consequence of the albedo effect, which measures the diffuse reflection of solar radiation out of the total solar radiation. A light surface – such as ice or snow – has a high albedo effect because it can reflect a large part of the Sun's light back towards space. By contrast, a dark surface – such as seawater – has a low albedo effect because it absorbs most of the energy from the Sun's rays and with it the heat. In other words, a sea without sea ice heats up much faster than a sea covered with ice.

“Not surprisingly, we can therefore also see that the warming is greatest in the areas where the sea ice has receded. Among other places, in the Barents Sea in the eastern Arctic”, Jens Hesselbjerg Christensen stressed.

The receding ice bodes ill for all levels of the ecosystem, he warned. Starting from algae, which are eaten by plankton, to small fish, birds and seals and up to polar bears.

Incidentally, the melting ice opens up potentially lucrative shipping routes, such as the Northern Sea Route and the Northwest Passage claimed by Russia and Canadarespectively, yet contested by other nations, Hesselbjerg Christensen said, warning of a geopolitical dimension to the issue.

a gender reveal party gone wrong...

Officials have blamed a gender reveal party for one of several wildfires raging in the US state of California.

A "smoke generating pyrotechnic device" at the event sparked the El Dorado fire, which has now spread over 7,000 acres.

It is one of more than two dozen blazes across the state.

California is currently experiencing a record heatwave, with Los Angeles reporting its highest-ever temperature of 49.4C (121F).

The National Weather Service described Sunday as "one of the hottest days since weather records began across much of southwestern California".

The largest blaze, known as the Creek Fire, has burned more than 73,000 acres and authorities said none of it has been contained.

It started at about 18:45 on Friday (01:45 GMT on Saturday) in the Sierra National Forest, an area of steep and rugged terrain.
