Warning of health crisis if we don't address Fossil Fuels and Climate Crisis: WMO report

The World Meteorological Organisation report on climate services this year focusses on health. It argues the need for tailored climate information and services to support the health sector in the face of more extreme weather and poor air quality, shifting infectious disease patterns and food and water insecurity.

If climate information is not used by the health sector for adaptation, population health can easily move backwards. 

“Practically the whole planet has experienced heatwaves this year. The onset of El Niño in 2023 will greatly increase the likelihood of breaking temperature records further, triggering more extreme heat in many parts of the world and in the ocean – and making the challenge even greater,” says WMO Secretary-General, Prof. Petteri Taalas.

“It is clear that by channelling investment and boosting collaboration, there is huge potential to go further and faster by enhancing the impact of climate science and services so that health partners get the support they need at a time when unprecedented changes to our climate are having an increasing impact,” says Prof. Taalas.

The report shows that integrated climate and health action makes a very real difference in people’s daily life. This includes early warning systems for extreme heat, pollen monitoring to help allergy sufferers and satellite surveillance for climate-sensitive diseases.

Aviation exhaust pollution, air quality, and impacts on Human Health - Melbourne Airport 3rd runway expansion

Melbourne Airport with 3 runways 2026 Option 1, Night 11pm-6am Flight Paths

Melbourne Airport is planning a third runway.

So I'm doing a science literature dive into reading the air pollution health impacts of aviation emissions...

You know, that coating you find over your car or house if you live under a flight path...this is soot, black carbon (BC), particulate pollution emissions from aircraft landing and taking off. But it's the particles you don't see that are problematic: Ultra Fine Particles (UFP) sometimes referred to as particulate matter with a size designation often classified as PM2.5, but often even smaller which can reach the furthest alveoli of your lungs..

These pollution particulates are not good for your health. UFPs have a high surface area and a capacity to adsorb a substantial amount of toxic organic compounds.

Studies indicate that the "exposure to aircraft emissions induce pulmonary and systemic inflammation, which potentially contributes to cancer, asthma, respiratory and coronary heart disease." (Bendtsen 2021)

In fact it is calculated that aviation emissions on a global basis cause about 16,000 people to die prematurely every year, and of this number about 5,000 people who live within 20 km of airports are estimated to die prematurely each year.

As Steve H L Yim et al (2015) study says: " primary PM2.5 emissions from aviation are a significant contributor to health risk when airport vicinity exposure is captured."

The study also highlights that the health cost of aviation emissions is actually at a magnitude larger than global aviation fatal accident costs, and on par with aviation's climate costs.

I wonder if Melbourne Airport have done their sums on the extra costs to health of people in the 20km radius of the airport with the extra aviation emissions a third runway will induce?

The No Third Tulla Runway campaign has articulated reasons to oppose development of the third runway. These include:

• Too much noise
• Contribution to global warming
• Loss of Woodland (a threatened ecosystem)
• Dodgy Economics
• Lack of Transparency

These are all relevant reasons to oppose the airport. The missing piece in this analysis is the aviation pollution impacts on air quality and human health at all scales: local, regional and global.

This article seeks to draw attention to some of the science on aviation exhaust emissions, air quality and human health.

Guest Post: The smoke from autumn burn-offs could make coronavirus symptoms worse.

I felt somewhat vindicated when this post appeared at The Conversation warning of hazard reduction burns smoke during the early pandemic. Correlation links had already been found between covid19 severity, increased mortality and higher levels of pollution.

Pandemic Ponderings: US study finds Air pollution link to Covid19 deaths

New research from the Harvard School of Public Health highlights a possible causal link between PM2.5 particulate pollution and Covid19 deaths.

That is, areas in the US with higher levels of PM2.5 particulate pollution have statistically significant higher rate of Covid19 deaths.

The aggregated data strongly suggests a link, while the researchers suggest more research is needed down to the individual patient medical data level to positively confirm the link.

The New York Times Lisa Friedman has reported on the study in an article titled New Research Links Air Pollution to Higher Coronavirus Death Rates.

Pandemic ponderings: Indications that High levels of Air Pollution exacerbate Covid19 spread (virus may be airborne)

First published as a Linked-in Blog post on March 26,2020.

While we all hunker down in physical distancing with Covid19. I have been chasing up reports on preliminary research by Italian scientists between high levels of Pm10 and Pm2.5 air pollution particulates increasing intensity and spread of Covid19 based on their research in northern Italy. 

I intially followed a link from a CMCC climate observatory (strong science reputation) post What Science Has to Say About the Coronavirus – Climate Crisis Connection. A Press Review (An excellent article by the way)

I came across a linked Italian news report dated 18 March reporting on a preliminary study by several Italian scientists regarding Pm10 and Pm2.5 particulates exacerbating Covid19 intensity and spread in northern regions of Italy. I documented this in my facebook timeline post with an english translation.

Guest Post: As India cuts aerosol air pollution, extreme temperatures may spike making heat health adaptation plans crucial

An insightful article into India's situation with regards to the air pollution problem and extreme heatwave temperatures. This year temperatures spiked to 51C in north western India: Wet Bulb Near 35 C — Heatwave Mass Casualties Strike India Amidst Never-Before-Seen High Temperatures.

The researchers argue that aerosols from air pollution are likely to have a substantial cooling impact at the moment, even as India experiences record temperatures. With roll out of renewables and the push to electrify vehicle transport, air pollution will likely be reduced increasing health outcomes. But it may be at the expense of a spike in temperatures at this time of year which will have a large heat health impact on the population, especially poorer people who cannot afford technological adaptation measures such as air-conditioning. It is another reason why recently implemented adaptation plans in India for heat health are so important, as well as taking effective and rapid emissions reduction on a global level in accordance with the UNFCCC Paris Agreement.

La Trobe Valley coal mine rehabilitation bonds increased to $254 million

This is a repost of an article by John Englart published at Climate Action Moreland.

On Friday 15th April Victorian Premier Daniel Andrews announced in Morwell the Victorian government's response to the final landmark inquiry into the 2014 Hazelwood Mine Fire. This response includes an initial $50 million in the Victorian state budget to implement the recommendations, and a major increase in the rehabilitation bonds for the three La Trobe Valley brown coal mines.

“The people of the Latrobe Valley have been completely vindicated. I’m so proud of their efforts. They never gave up and neither will we.” said Premier Dan Andrews.

Port Augusta: Transition from #coal to #solar critical say locals

First published at nofibs.com.au

The Port Augusta community have called for South Australian Premier Jay Weatherill to step up to help fund construction of a solar thermal power station. The call from Repower Port Augusta comes in reponse to an Alinta Energy assessment (Draft Milestone 3 Balance of Study Report March 2015 PDF) that found a solar thermal power station was still uneconomic to build without government support. The proposed 50MW project is estimated to cost $577 million, about $150 million greater than it's commercial viability.

Australia currently does not have any 'baseload' concentrating solar thermal with molten salt energy storage power plants. The Port Augusta proposed power station could be Australia's first using a Concentrating Solar Thermal (CST) power tower with up to 15 hours molten salt energy storage included.

These type of CST plus molten salt energy storage power plants are already producing electricity or under construction at Crescent Dunes in Nevada, USA (110MW), Gemasolar in Andalucía, Spain (20MW), Planta Solar Cerro Dominador at Calama, Chile (110MW under contruction), Rice Solar energy project in California, USA (150MW), and Supcon Solar Project in China (50MW under construction).
