Climate change catching up fast

From floods to extreme heat, 10 of the worst climate-linked disasters this year caused at least $120.8 billion worth of damage, says a study released by the charity Christian Aid.

Extreme weather driven by climate change hit every populated continent this year, the British relief organisation said, warning urgent action was needed to combat global warming.

Climate-linked disasters caused massive damage in 2018 .
‘‘This report shows that for many people, climate change is having devastating impacts on their lives and livelihoods right now,’’ said Kat Kramer, who heads Christian Aid’s work on climate issues.

Experts said a warming world would lead to sweltering heatwaves, more extreme rainfall, shrinking harvests and worsening water shortages, causing both monetary losses and human misery.

Almost 200 nations were aiming to limit the rise in average world temperatures under the landmark 2015 Paris Agreement, though some warn progress to meet targets has been slow.

The 20 warmest years on record have been within the past 22 years, the United Nations said last month, with 2018 on track to be the fourth hottest.

The most expensive climate-linked weather events of the year were hurricanes Florence and Michael, which caused at least $75 billion worth of damage as they slammed into the United States, the Caribbean and parts of central America, the report said.

The US also suffered at least $US9 billion of losses from wildfires that caused dozens of deaths and destroyed thousands of homes in California.

Japan was badly hit by severe floods during the summer, followed by the powerful typhoon Jebi in the (northern) autumn, which together caused more than $US9.3 billion in damages, the report said.

It also cited droughts in Europe, floods in southern India and Typhoon Mangkhut in the Philippines and China among the most expensive climate-linked disasters of 2018.

The report’s authors collated total cost figures using data from sources including governments, banks and insurance firms, though in some cases the figures only covered insured losses and also failed to take account of the human costs of such events.

They added that rising temperatures would continue to drive extreme weather events as they urged action to prevent further global warming, which would impact the poorest and most vulnerable communities hardest.

‘‘The impacts of climate change are no longer subtle,’’ Penn State University atmospheric science professor Michael Mann said.

‘‘The world’s weather is becoming more extreme before our eyes — the only thing that can stop this destructive trend from escalating is a rapid fall in carbon emissions.’’

Frogs show signs of immunity to chytrid fungus pandemic that has wiped out about 200 species

A disease caused by a highly contagious fungus has wiped out as many as 200 species of frog worldwide since the 1970s, and pushed many more to the brink of extinction.
The Panamanian golden frog is presumed to be extinct in the wild.
But researchers now believe that some frogs may be developing a resistance to the deadly chytrid fungus.

When chytridiomycosis wiped through a biodiversity hotspot called El Cope in Panama in 2004, scientists said the spread was so rapid that, in places, dead frogs littered the forest floor.

In the study published today in Science, researchers have documented the recovery of nine frog species in three regions of Panama, including El Cope, and have observed infected frogs showing no ill effects from the fungus.

Cyclone Kelvin blue alert issued as apocalyptic clouds bring heavy rainfall to Broome

Broome has had the first taste of the storm system expected to develop into the strongest cyclone of the season, with a blue alert issued for a tropical storm which has already caused widespread flooding.
A low-slung storm front approaches Cable Beach in Broome on Thursday.
The system is forecast to develop into Tropical Cyclone Kelvin, bringing wind gusts of up to 165 kilometres per hour and isolated rainfall of up to 500 millimetres.

The blue alert applies to people between Cape Leveque and De Grey in the Kimberley and Pilbara, including the tourist town of Broome, with a severe tropical cyclone likely to develop later today or tomorrow.

People in the district are being warned to prepare their properties and take shelter.

US report finds climate change 90% manmade, contradicting Trump officials

A comprehensive review by 13 US federal agencies concludes that evidence of global warming is stronger than ever and that more than 90% of it has been caused by humans.

The 477-page report said it’s ‘extremely likely’ that global warming is manmade.
The conclusion contradicts a favorite talking point of senior members of the Trump administration.

A 477-page report released on Friday said it was “extremely likely” – meaning with 95 to 100% certainty – that global warming is manmade, mostly from carbon dioxide through the burning of coal, oil and natural gas.

The energy secretary, Rick Perry, and Environmental Protection Agency chief, Scott Pruitt, have said carbon dioxide is not the primary contributor to global warming.

Since 1900, the report says Earth has warmed by 1C and seas have risen by 8in. Heatwaves, downpours and wildfires have become more frequent.
