National: Air Pollution Alert Issued for Sydney as Ozone Levels Rise

An air pollution alert has been issued for Sydney residents as ozone levels continue to rise beyond government standards.

New South Wales Health said the ozone excess, which causes “poor” air quality on Tuesday, could affect people with respiratory conditions.

Ozone is a pungent gas resulting from chemical reactions between atmospheric gases and nitrogen oxides from car-vehicle exhausts, which can cause chest pain, coughing and throat irritation when inhaled. Hot weathers could exacerbate ozone pollution levels, a statement by NSW Health said.

Dr Ben Scalley, Director of Environmental Health Branch at NSW Health said parents are advised to keep watch on their children when ozone levels are high.

“Ozone levels are higher outdoors than indoors, so parents should limit the time their children with asthma play outside as they are more susceptible to the effects of ozone pollution,” said Scalley.

Scalley reminded that people should remain alert to the link between high temperatures and ozone pollution.

National: One Nation Senator Denies Climate Change is Happening

One Nation senator Malcolm Roberts has claimed that the CSIRO’s climate change science had no “empirical proof”.

In his Monday press conference, Roberts released his 42-page report titled “On Climate, CSIRO Lacks Empirical Proof”, in which he wrote that the agency “relies on unscientific Australian and overseas manipulations of data that have fabricated warming temperatures”.

Roberts also published his letter to Dr Larry Marshall of the CSIRO, saying that climate policies is detrimental to “key industries” and people’s job security.

The report also criticised former Prime Minister Julia Gillard’s carbon tax policy and claimed that Great Barrier Reef is not “dying”.

“We have had complete failure of science in policies that has cost Australian taxpayers and citizens and Queensland residents billions of dollars and has cost lives,” said Roberts in the press conference.

Roberts said the CSIRO and weather bureau should face an independent inquiry over the lack of “empirical evidence” that human activity affects climate.

The CSIRO maintained its position in a statement: “CSIRO stands behind its peer-reviewed science on environment, climate and climate change.”

Finance: Phasing Out Coal Won’t End Aus Economy, Says Australia Institute

Phasing out of coal production would not hurt Australia’s economy, according to an Australia Institute research.

The study found that the national economic impact would be insignificant if the Government put a moratorium on coal mines opening and expansion, although it could hurt regional areas relying on the industry.

“The world outlook for coal is fairly bleak. We don’t see much likelihood of strong market conditions for coal over the longer term,” said the research’s leader at Victoria University’s Centre Of Policy Studies, Professor Philip Adams to ABC’s AM. “There is enough coal in mines that are operating or will be operating to continue the level of exports that we see now.

“But, thereafter, coal production will slow as new mines which otherwise would come on are not allowed to come on.

“Is this a bad thing for Australia? The answer is no.”

Australia Institute chief economist, Richard Dennis said the impacts of a moratorium on the economy will be “trivial… Literally, when you graph the economy with a moratorium and without a moratorium, you need a microscope to find the difference.”

The report concluded with calls for a moratorium on new coal mines and expansions, and that the Government “should expect minimal economic disruption from doing so.”

The mining industry has rejected the study’s findings. The Chief Executive of the World Coal Association, Benjamin Sporton said coal still plays an important role in providing energy to the world, with coal currently providing 41 per cent of the world’s electricity and 90 per cent of Australia’s eastern seaboards.

“To try and say we’re going to move away from a fuel that provides that much of the world’s electricity, I just don’t think is realistic,” said Sporton.

The Executive director of Minerals Council of Australia, Greg Evans said the report is “a nonsense” and “just more anti-coal rhetoric, not analysis”.

“Only the green movement and their mouthpieces such as the Australia Institute (TAI) would be able to contend shutting down Australia’s second largest export industry would have limited economic impact,” said Evans in a statement.

“Annual coal exports at $38 billion in 2014/15 are almost twice those of beef, wheat, wool and wine combined so under their logic eliminating those great industries would also have negligible consequences.

“There are also 44,000 direct jobs in the coal sector and including related jobs, the number is around 150,000 and the majority of those are in regional areas. The TAI should travel to the Hunter Valley and Bowen basin coal towns and promote their economic thesis that the coal industry doesn’t matter.”

Prime Minister Malcolm Turnbull has previously rejected calls for a moratorium, saying that it would not help “one iota” to relieve climate change if coal exports were to be stopped.

Construction appears to be holding the Aus economy in the green so far with increased foreign spend on property leading to more capital expenditure on equipment sales. The advent of price comparison sites like equipment hunt issuing excavator quotes for free make the market more competitive with buyers getting the best deals.

Environmental: NASA Releases Global Climate Change Report

NASA has published data showing global temperature and rainfall patterns that may change through the year 2100 due to the increase of greenhouse gas emissions concentrating in the Earth’s atmosphere. The dataset shows projected changes worldwide responding to growing carbon dioxide simulated by 21 climate models.

According to NASA Chief Scientist, Ellen Stofan, “NASA is in the business of taking what we’ve learned about our planet from space and creating new products that help us all safeguard our future,”. She states that “with this new global dataset, people around the world have a valuable new tool to use in planning how to cope with a warming planet.”

The NASA climate projections provide a detailed view of future temperature and precipitation patterns around the world at a 25km resolution, covering the time period from 1950-2100.
