Extinction Rebellion climate protesters shut down a major intersection in the Melbourne CBD during peak hour on Thursday.
Up to 100 protesters took part in the protest and were met with a strong police presence, Nine News reports.
They group took over the intersection of Latrobe Street and Queen Street at around 8am, blocking traffic for 20 minutes, before moving down Latrobe Street.
The activist group said the “colourful and dramatic protest” would be the first of three days it planned to create disruptions in the heart of the city, after blocking a major freeway exit during peak hour on Tuesday.
At least 102 climate activists from seventeen countries representing Greenpeace, Stay Grounded, Extinction Rebellion, Scientist Rebellion and other climate justice groups are still being detained in Geneva, Switzerland 20 hours after a peaceful protest against Europe’s largest annual private jet fair, the European Business Aviation Convention & Exhibition (EBACE) in Geneva.
“A unique, European coalition of courageous activists from 17 countries severely disrupted the excessive champagne party of a super-rich elite – Europe’s largest private jet sales event. Their demand is unequivocal, private aviation should be consigned to the history books. We support the activists and demand their immediate release.” – said Klara Maria Schenk, a transport expert for the European Mobility For All campaign.
Contrary to several misleading media reports, the activists never entered the taxiways or runways of the airport. The activists make it clear that at no time they intended to disrupt commercial air traffic at Geneva Airport. A spokeswoman for air traffic control agency Skyguide confirmed protestors had not accessed the runway during the incident, according to Aviation International News.
Two billion people, including many Australians, will find themselves living in dangerously hot places this century if global warming reaches 2.7℃, research released today reveals.
The authors calculated how many people would be left outside the “human climate niche” by 2100. The niche is defined as places with an average temperature of about 13℃, or about 27℃ in the tropics. Human population has historically peaked in these areas.
The world is on track for 2.7℃ of warming by 2100. This would push a third of people on Earth outside the human climate niche. This includes people in parts of northwest Australia such as Darwin, Broome and Port Hedland. It also includes parts of Southeast Asia, India, Africa and South America.
Limiting warming to 1.5℃ would substantially reduce the number of people exposed, including most of those affected in northwest Australia.
We were not involved in the research, which was conducted by researchers in the United Kingdom, China, Europe and United States. We are Australian experts in the health implications of global warming. Below, we discuss the broader implications of these globally significant findings.
What is the human cost of global warming?
The research calculated the number of people outside the “human climate niche” under different demographic scenarios and levels of warming. Exposure to unprecedented heat was the main factor pushing people out of the niche.
This includes an average temperature greater than or equal to 29℃, as well as a high number of days with a maximum temperature above 40℃ or in humid places, with a wet-bulb temperature greater than 28℃. The wet-bulb temperature (as opposed to the standard dry-bulb temperature) reflects humidity and is a method used to measure heat stress. That’s because it’s the point at which sweating is no longer effective as a means of cooling.
The study says a wet-bulb temperature of 35 ℃ can be fatal, especially for vulnerable people, because the body can no longer cool itself.
Above the present level of about 1.2 ℃ global warming, the authors found exposure to unprecedented average temperatures increased markedly, along with increased exposure to temperature extremes.
But 2.7 ℃ of warming threatens a third of the world’s population. The below map shows where in the world people will suffer the worst heat. Almost the entire area of some countries, such as Burkina Faso and Mali in West Africa, would be exposed to unprecedented heat.
Why is warming a health hazard?
Just last week, the World Meteorological Organization predicted global surface temperatures would rise to record levels within the next five years. The temperature is also likely to temporarily climb 1.5℃ above pre-industrial levels.
This spells trouble for human health. Even incremental warming increases exposure to health hazards including potentially deadly heatwaves, infectious diseases and diet-related health issues.
Let’s be clear. A 1.5℃ world will result in injury and death, particularly for people in Asia and Africa. Importantly, the people most at risk will be the least capable of protecting themselves: children, the elderly and those with existing health conditions.
While populations closer to the equator are more likely to experience heat-related harm, Australians are by no means immune.
For example, a 2019 study found heat-related health issues in Australia have been grossly underestimated. It found more than 36,000 deaths between 2006 and 2017 were attributable to heat.
And experts predict Darwin could experience an average 265 days a year above 35℃ in a 3℃ warmer world.
Historically health has rarely been included in these economic assessments, much less ethical considerations. Emissions reduction policies need to consider health and equity issues, and in doing so can provide governments with a strategic rationale to act.
Pursuing adaptation measures in an effort to reduce the harmful effects of existing climate change is vital, but to protect the health of all, it is critical that we pursue strong emissions reduction measures.
Developing healthier climate policies
Australian climate action targets have improved under the Albanese government, however they remain incompatible with keeping warming to 1.5℃.
A commitment to develop and implement a National Health and Climate Strategy and establish a National Sustainability and Climate Unit are promising initiatives. This will help to address our woeful performance in a recent assessment showing how national climate commitments don’t link with health.
Last week, the Victorian Government committed to reducing emissions by 75-80% compared with 2005 levels by 2035. Their analysis indicates it will lead to A$5.7 billion in health benefits from improved air quality between 2035 and 2045.
As today’s new research states, the findings highlight the need for “more decisive policy action to limit the human costs and inequities of climate change”. Australia, in particular, must protect children, the elderly and the broader population from the harms they face in a warmer world.
