Antarctica is under the risk of ‘sudden changes’ that may have disaster results

21 According to the examination of Australia and international scientists, Antarctica may undergo sudden and potentially irreversible changes with disaster results unless there is an emergency action to reduce greenhouse gas emissions.

The review of Antarctica Science, published in Nature magazine, found that the changes faced by the Southern continent were connected to each other and put pressure on global climate, sea level and ecosystems.

Various risk emphasizes: including the following:

  • Western Antarctica Ice layer can collapse the “serious risk”. If this were, it would increase sea levels more than three meters and threaten the worldwide coastal cities and communities.

  • Acceleration of sea ice floating in the ocean around Antarctica. This has a series of hitting effects, including worsening heating, by increasing the amount of sun temperature held in the ocean and increasing the risk of extinction of ice -based species such as emperor penguins.

  • The potential rapid slowdown of the Southern Ocean overturning circulation will be able to change the climate of the world for centuries. In addition to other changes, it means that vital nutrients remain at the sea base instead of returning to the surface of the biological systems.

Dr Nerilie AbramAt the Australian Antarctica Department, the chief scientist and the chief author of the study said:

The only way to avoid further sudden changes and their extensive effects is to reduce greenhouse gas emissions as fast to limit global warming as close to 1.5C as possible.

Governments, businesses and communities will need to take into account these sudden antarctic changes observed in future planning for climate change effects, including Australia.

AEMO, large -scale energy production in the next decade to grow 21%

. Australian Energy Market Operator (AEMO) has published its annual report on the investments required to keep the national electricity network reliable for the next decade.

Found that the appearance healed a year ago – the promised new generation is delivered to all expected investments in storage and transmission connections.

General Manager of AEMO, Daniel WestermanThe report said in the report that 10 -year investment pipeline is healthy to manage energy reliability .. However, in the next decade, a large number of electrical stations – 11GW, almost all coal power – the new infrastructure, which means that “timely delivery” means critical.

The operator estimates that the demand for large -scale electricity generation will increase in the next decade due to the “rapid expansion of data centers, business electricity and prospective industrial energy users more wider”.

This said that this summer is estimated due to a “small reliability gap of 80 MW in Queensland because of“ higher generator availability, maximum demand forecasts and delayed project activation forecasts ve and a warning capacity will be needed to meet it.

If the Torrens Island B gas plant retired as previously planned, a larger reliability gap of 390mW in the next financial year is estimated-Ancak modeling has not been thinking about a principle agreement to extend the generator’s life for two years.
