Abnormal heat spreads floods and wildfires globally

From the Arctic Circle to tropical Africa, abnormal heat is bringing mayhem and destruction and costing lives.

LONDON, 17 September, 2020 – Across the planet, abnormal heat is exacting a lethal toll. The west coast of the US is up in flames. Over recent months unprecedented high temperatures have been melting permafrost in Siberia, within the Arctic Circle. Fires have spread; many thousands of acres of taiga have been laid waste.

Across many parts of Africa unseasonable torrential rains are causing loss of life and crops.

Climate scientists are careful about attributing any one severe weather event to climate change until all data is gathered and a proper analysis is made.

But looking at various weather patterns around the world, fundamental changes in climate are happening – most related to big increases in temperature.

Along the western seaboard of the US people are having to cope not only with a prolonged drought but with temperatures which are way above normal.

As the ground and brush at the base of trees dries out, the ideal conditions for wildfires are set.

Over recent days more than 40,000 people in the state of Oregon have been told to evacuate their homes: dozens of people are believed to be missing in the mayhem caused by the fires.

“The debate is over.This is a climate damn emergency. This is real and it’s happening”

Kate Brown, Oregon’s governor, says that over three days recently more than 1,400 square miles of land was destroyed by fire – nearly double the amount burned over a typical year in the state.

“We have never seen this amount of uncontained fire”, said Brown.

“While our state reels from this horrific fire storm of hot weather, high winds and drought conditions, this will not be a one-time event.

“Unfortunately it is the bellwether of the future. We are feeling the acute impacts of climate change.”

Last month a group of Oregon’s leading industrialists launched a court action against Governor Brown, saying she overstepped her authority by introducing measures aimed at cutting carbon emissions in the state.

Further south in California, wildfires continue to burn. The skies of San Francisco and other cities have turned red in recent days. Smoke from the fires is causing severe air quality problems.

Gavin Newsom, California’s governor, launched an angry attack on President Trump and others who are sceptical about climate change, while visiting an area of the state destroyed by fire.

“The debate is over” said Newsom. “This is a climate damn emergency. This is real and it’s happening.”

Studies say that since the early 1970s California has registered a more than fivefold increase in the annual incidence of forest fires.

A similar growing trend in abnormal heat and wildfires is being recorded in many parts of Siberia: soaring temperatures have been a big factor. In one Siberian town temperatures reached 38°C in mid-June – 18°C above the usual daytime temperature for the time of year.

Less reported on but a cause of death and hardship to some of the world’s poorest countries are floods that have been destroying homes and crops across large areas of the African continent.

In Somalia, still trying to establish itself as a functioning fully independent state in the face of terrorist attacks, nearly a million people have been affected by severe flooding in recent months.

Sudan and Ethiopia have also been subject to widespread flooding.

Ancient coal fires led to prehistoric extinctions

Did eruptions set ancient coal fires burning? Global heating happened 250 million years ago, just as it is happening now.

LONDON, 29 June, 2020 – Geologists have linked one of the planet’s most devastating events to the burning of fossil fuels, as ancient coal fires set in train a global extinction wave.

Emissions from the fires on a massive scale can be connected to catastrophic events that extinguished most of life on Earth – and this time, humans were not to blame.

It all happened more than 250 million years ago, at the close of the  Permian period. And this time the match that lit the flame was massive but slow volcanic eruption in what is now Siberia, a burning that continued for two million years.

In a new study in the US journal Geology, US, Canadian and Russian scientists report that in the course of six expeditions to collect rock samples from a formation known as the Siberian Traps they repeatedly found samples of charred wood and fragments of burnt coal.

“Our study shows that the Siberian Traps magmas combusted large quantities of coal and organic matter during eruption”

Geologists have identified five major extinctions of life in the past, and biologists now argue that – because of human action – a sixth has begun. But the worst of these was the Permian: the oceans acidified to lethal levels as carbon dioxide ratios in the atmosphere soared, and tropical ocean temperature reached fever pitch at 40°C.

Altogether, 96% of marine species disappeared, and 70% of land creatures. The event closed the Permian era, and ushered in the Triassic, and the beginning of the dinosaurs.

For geologists, the past is the key to the present: what happened once can happen again. And it now seems that the fuel that generated the high temperatures and acidic oceans was coal, laid down in the 50 million years of the Carboniferous that ended with the arrival of the Permian.

The Permian catastrophe has puzzled palaeontologists for decades, and the latest finding is not likely to be the end of the argument. Catastrophic climate change has been linked to most of the ancient extinctions. High carbon levels in the late Permian atmosphere have been implicated from the start.

Spur to action

Highly acidic seas – the oceans are the oldest, largest and richest of life’s habitats – have been named as prime suspect. Damage to the ancient ozone layer has also been cited. But in all cases, the cause of the sudden surge in atmospheric carbon has been up for debate: humans are implicated in climate change now. But what caused it then?

The answer: slowly slurping fiery magma (molten rock) from ancient volcanic sources, enough to cover 7 million square kilometres; enough to amount to 4 million cubic kilometres of once-smoking basalt that spilled over vast areas of old forest, buried peat and deeper fields of coal.

“Our study shows that the Siberian Traps magmas intruded into and incorporated coal and organic material. That gives us direct evidence that the magmas also combusted large quantities of coal and organic matter during eruption,” said Linda Elkins-Tanton, of Arizona State University, who led the research.

“Seeing these similarities gives us extra impetus to take action now, and also to further understand how the Earth responds to changes like these in the longer term.” – Climate News Network
