TODAY. Media angst about Ukraine, Australia’s election campaigning – but are we forgetting global heating?

Australia sure is an island, and not just geographically speaking. Australia is now playing its role, joining USA in the weapons-to-Ukraine frenzy. But that’s about the extent of our interest in matters overseas.

We hardly noticed the plight of Pacific islands as sea levels rise, though we’re quick to worry about China’s military influence in the region.

It seems to take a young student of Indian ethnic background to mention climate change. Are Australians noticing what is happening in India and Pakistan? Global heating has become all too important there – as extreme heat continues, with drastic effects on health, food production, fires, electricity supplies. For many Indians, life is near to becoming unliveable.

Australia enjoys a sort of false immunity to climate change. Our leaders of both big political parties haven’t really woken up to this, despite bushfires and floods. Are they even aware of what is happening in India?

Pakistan, India reel under intense heat wave

Market Screener, By Jibran Ahmad and Sumit Khanna, 29 Apr 22,

PESHAWAR, Pakistan/AHMEDABAD,India (Reuters) -Pakistan issued a heat warning after the hottest March in 61 years while in parts of neighbouring India schools were shut and streets deserted as an intense heave wave on Friday showed no signs of abating.

Pakistan’s Federal Minister for Climate Change, Sherry Rehman, urged the federal and provincial governments to take precautionary measures to manage the intense heat wave, which touched highs of 47 degrees Celsius (116.6 Fahrenheit) in parts of the country.

“South Asia, particularly India and Pakistan are faced with what has been a record-breaking heatwave. It started in early April and continues to leave the people gasping in whatever shade they find,” Rehman said in a statement.


Temperatures were predicted to rise by 6 to 8 degrees Celsius above average temperatures after the hottest March on record since 1961, she said.

More than a billion people are at risk of heat-related impacts in the region, scientists have warned, linking the early onset of an intense summer to climate change. For the first time in decades, Pakistan had gone from winter to summer without the spring season, Rehman said.

The government has also told provincial disaster management authorities to prepare urgently for the risk of flash-flooding in northern mountainous provinces due to rapid glacial melting, Rehman said.

Glaciers in the Himalaya, Hindu Kush and Karkoram mountain ranges have melted rapidly, creating thousand of glacial lakes in northern Pakistan, around 30 of which were at risk of sudden hazardous flooding, the climate change ministry said, adding around 7 million people were vulnerable.

A senior scientist at the India Meteorological Department said https://twitter.com/ANI/status/1519938880824176641?s=20&t=NgygE8RS-D4wfM-OJxp9Ew on Friday heat conditions would persist for at least the next three days, but that temperatures would fall after the arrival of monsoons, expected in some parts by May.

The health problems triggered by the heatwave were posing a bigger worry than the expected fourth wave of COVID-19, doctors in India said.

“We are getting many patients who have suffered heatstroke or other heat-related problems,” said Mona Desai, former president of Ahmedabad Medical Association in the western Indian state of Gujarat.

She said that 60-70% of the patients were school-aged complaining of vomiting, diarrhoea, abdominal colic, weakness and other symptoms.

Roads were deserted in Bhubaneshwar, in India’s eastern state of Odisha, where schools have been shut, while neighbouring West Bengal advanced the school summer break by a few days.

Delhi sweltering under extreme heat, electricity shortage

India is facing the worst electricity shortage in more than six years as
Delhi saw its hottest April in 12 years on Thursday at a maximum of 43.5C.
The temperatures in the national capital are predicted to linger around 44C
with peak summer heat still to come before the cool monsoon rains in June.

The extreme heat parching across large swathes of south Asia this week has
also prompted health officials in the western state of Gujarat to take
measures, as they braced for a potential spike in patients. Meanwhile, the
leap in power demand has left India scrambling for coal, with inventories
running lowest pre-summer levels in at least nine years. Several states
including Rajasthan and Haryana in the north and Andhra Pradesh in the
south observed the worst power cuts in over six years as the government
struggled to manage surging power demands.

Climate change ‘already’ raising risk of virus spread between mammals

 Mammals forced to move to cooler climes amid global warming are
“already” spreading their viruses further – with “undoubtable”
impacts for human health, a new study says. The research, published in
Nature, uses modelling to map how climate change could shift the geographic
ranges of 3,100 mammals species and the viruses they carry by 2070.

It finds that climate change is increasingly driving new encounters between
mammal species, raising the risk of novel disease spread. The world’s
“biodiversity hotspots” and densely populated parts of Asia and Africa
are most likely to be affected. The findings suggest that climate change
could “easily become the dominant [human] driver” of cross-species
virus transmission by 2070, the authors say.

For the first time, U.S. renewable energy output exceeds nuclear generation, EIA finds

Utility Dive, By Elizabeth McCarthy. 28 Apr 22,      

Dive Brief:

  • The growing number of large solar and wind energy projects resulted in renewable generation beating out nuclear energy last year, the U.S. Energy Information Administration said on Tuesday. 
  • The nation has seen a steady rise in renewable generation, with the biggest share from solar, which is expected to continue because of the lower cost and greater safety of this intermittent power resource, clean energy advocates say. That is despite the Biden administration’s multi-billion dollar program to keep online baseload nuclear power plants scheduled to retire.
  • Natural gas supplies the biggest share of electricity in the county but its share is also expected to decrease over the next three decades. EIA projects solar will replace it as the dominant source of generation in the U.S. by 2050.
  • Dive Insight:Utility-scale renewable generation in the U.S. reached 795 million MWh in 2021, compared to 778 million MWh of nuclear generation.“This is a ‘good news’ story,” said Ralph Cavanagh, Natural Resources Defense Council energy program co-director.
  • The news gets better for renewables when considering that private investments in clean technology rose to over $27 billion in 2021, up from about $20 billion in 2020, according to a report by the American Investment Council released last week. Private equity companies over the last decade have invested close to $150 billion and backed more than 1,000 clean technology companies in the U.S., it added.
  • The biggest mover on the U.S. generation front has been solar as installation costs have dropped 70% over the last decade. That has led “the industry to expand into new markets and deploy thousands of systems nationwide,” according to a Feb. 11 joint statement by the Edison Electric Institute, NRDC and the Solar Energy Industries Association. Supply chain issues pushed up prices last year “but did not eliminate solar power’s competitive advantages in retail and wholesale markets,” the organizations wrote in their joint statement to the National Association of Regulatory Utility Commissioners. EIA’s April 26 analysis does not include rooftop solar or other smaller renewables serving predominantly onsite demand. Factoring in just “end-use solar, the milestone for surpassing nuclear generation would have been reached earlier,” said Syne Salem, an EIA engineer. The tally also excludes small-scale wind and some industrial and commercial combined-heat-and-power systems.

Poor outlook for Joe Biden’s $6 billion effort to keep old nuclear reactors going

Biden’s $6B nuclear plan hits ’24th hour’ roadblock

By Peter Behr, Hannah Northey | 04/28/2022  The Biden administration’s $6 billion effort to keep struggling nuclear plants operating is facing a barrier in Michigan and California.

A top energy executive yesterday confirmed that one of the first plants poised to qualify for financial support under the Energy Department’s newly unveiled lifeline — Michigan’s Palisades plant — remains on schedule to close May 31, throwing the Midwestern state’s climate goals into question.

Leo Denault, CEO of Entergy Corp., owner of the Palisades plant, told security analysts yesterday that a buyer who succeeded in acquiring the generator would also bear refueling costs and other expenses.

“We will work with any qualified party,” he said. But he added, “I do want to be very clear. Entergy is exiting the merchant nuclear business. The plant will have to stop operating in May. We’ll be out of fuel.”………………….

Pacific Gas and Electric Co., the Diablo Canyon owner, has also said the DOE offer does not change its intention to close the California facility. Diablo Canyon’s reactors 1 and 2 have planned closing dates of November 2024 and August 2025, respectively……….

A spokesperson for DOE said yesterday they were unable to speak about the unique challenges and closure decisions facing various nuclear plants, nor could they provide a precise number of struggling plants potentially eligible for financial assistance……………………………    https://www.eenews.net/articles/bidens-6b-nuclear-plan-hits-24th-hour-roadblock/

Photovoltaics vs. nuclear power on Mars

Photovoltaics vs. nuclear power on Mars   https://www.pv-magazine-australia.com/2022/04/29/photovoltaics-vs-nuclear-power-on-mars/

Solar might be more efficient than nuclear energy to supply power for a six-person extended mission to Mars that will involve a 480-day stay on the planet’s surface before returning to Earth, according to new US research.

APRIL 29, 2022 EMILIANO BELLINI   Researchers at the University of California, Berkeley, have compared how PV or nuclear energy could power a crewed outpost for an extended period on Mars and have determined that solar offers the best performance.

“Photovoltaic energy generation coupled to certain energy storage configurations in molecular hydrogen outperforms nuclear fusion reactors over 50% of the planet’s surface, mainly within those regions around the equatorial band, which is in fairly sharp contrast to what has been proposed over and over again in the literature, which is that it will be nuclear power,” said UC Berkeley researcher Aaron Berliner, noting that two energy sources were compared for the power supply of a six-person extended mission to Mars involving a 480-day stay on the planet’s surface before returning to Earth.

The US team considered four different scenarios: nuclear power generation with the miniaturised nuclear fission Kilopower system, PV power generation with battery energy storage, PV power generation with compressed hydrogen energy storage produced via electrolysis, and hydrogen generation with compressed hydrogen energy storage (PEC).

In our calculations, we assumed a capacity factor of 75% to account for the solar flux deviation throughout the Martian year and sized energy storage systems to enable 1 full day of operations from reserve power,” the group explained. “We then calculated the carry-along mass requirements for each of the power generation systems considered.”

The scientists found that, of the three PV-based power generation options, only the photovoltaics-plus-electrolyser system outcompetes the nuclear system based on carry-along mass. They also said that the optimal absorber bandgaps for the PV systems depend heavily on the location on the surface of Mars, the total depth of the air column above a given location, gradients in dust and ice concentrations, and orbital geometry effects that cause different effective air column thicknesses for locations near the poles.
