Ocean temperatures have been steadily rising due to human-caused global warming, which in turn means record hottest years have become increasingly common.

Key Points:

Ocean temperatures have been steadily rising due to human-caused global warming, which in turn means record hottest years have become increasingly common.
The last time ocean temperature records were broken was 2016 and before that it was 2015.
The last year we experienced a record cold year was way back at the start of the 20th century.
But what is remarkable about the past year is the huge ongoing spike in global ocean temperature which began in April last year.

How big is the jump in heat?

You can see the surge in heat very clearly in the near-global ocean surface temperature data.
The trend is clear to see. Earlier years (in blue) are typically cooler than later years (in red), reflecting the relentless march of global warming. But even with this trend, there are outliers. In 2023 and 2024, you can see a huge jump above previous years. These record temperatures have been widespread, with the oceans of the southern hemisphere, northern hemisphere and the tropics all reaching record temperatures.

What’s behind the surge?

The extra heat pouring into the oceans results in a gradual rise in temperature, with the trend possibly accelerating.
But this alone doesn’t explain why we have experienced such a big jump in the last year.
Other natural heat-transferring oscillations, such as the Indian Ocean Dipole or the North Atlantic Oscillation, may play a role.

Why is this important?

But the extra heat manifests underwater as an unprecedented series of major marine heatwaves.
If the heat spikes too much and for too long, they have to move or die.
Marine heatwaves can lead to mass death or mass migration for marine mammals, seabirds, fish and invertebrates.
They can cause vital kelp forests and seagrass meadows to die, leaving the animals depending on them without shelter or food.

What’s going to happen next?

In the next few months, forecasts suggest we have a fair chance of heading into another La Niña.
If this eventuates, we might see slightly cooler temperatures than the new normal, but it’s still too early to know for sure.

We landed a camera on Venus before seeing parts of our own oceans – it’s time to ramp up observations closer to home

Its much denser atmosphere enables a greenhouse effect on steroids, with surface temperatures approaching 500°C.

Key Points:

Its much denser atmosphere enables a greenhouse effect on steroids, with surface temperatures approaching 500°C.
We have managed to land a camera on the surface of Venus, with the Soviet space probe Venera 9 in 1975.
Like the “Earth rise” image captured during the Apollo 8 mission in 1968, this again proved the power of visual imagery.

Direct observations

But as powerful and all-encompassing as these observations are, we still make surprise discoveries, such as vent systems on the seafloor and life in under-ice cavities.
This is why we need to continue exploring and ramp up our capacity to measure the oceans directly.
Nowhere is this more true than in the Southern Ocean, the connector of all oceans.

Fostering collaboration

While it is not quite Venus in terms of difficulty, measurements have to target and prioritise the major science questions.
Earlier this year, more than 300 researchers gathered for the first Southern Ocean Observing Symposium in Hobart to express their growing concern.

The risks of the unknown

It isn’t cheap to track changes in such a remote location.
Sending ships and deploying robust instrumentation, and then retrieving the gear and data, all adds up.
The lack of direct observations is one reason we continue to be surprised by changes in the region.

Professor Dehui Wan from NTHU's Institute of Biomedical Engineering has developed a "super-cooling nanofiber" membrane, the effect of which is akin to clothing buildings in cooling attire.
Covering roofs with this thin, pliable, and durable fiber membrane, which is resistant to UV rays and acid rain, is like adorning buildings with cooling attire.
In the blistering sun, Professor Wan led his students as they conducted experiments on the roofs of campus buildings.

What harm could one coal mine do? Plenty – 1.7 million Hiroshima bombs of heat for starters

Retrieved on:

Tuesday, August 22, 2023

This year, the Australian government rejected Clive Palmer’s coal mine proposal – but approved three others.

Key Points:

This year, the Australian government rejected Clive Palmer’s coal mine proposal – but approved three others.
Why are we still approving coal projects when climate impacts are intensifying?
Unusually, Environment Minister Tanya Plibersek and her department were required to account for climate impacts in a recent decision.
It’s no wonder environmental organisations are filing lawsuits to try to stop these mines.

One new mine is the same as millions of nuclear bombs of heat

But how can Australia’s environment minister reason that new coal mines won’t do too much damage to the climate?
One is the assumption that if we don’t dig up fossil fuels, someone else will.
Human activity is causing about 7.8 zettajoules of extra heat to be added to the Earth’s climate system every year.
We can think of it instead as around 1.7 million Hiroshima bombs worth of extra heat.
That, in turn, would trap heat equivalent to roughly 43 million Hiroshima bombs.

We can’t predict the outcome of the case – it could go either way.

Rishi Sunak’s green backtracking contrasts strongly with previous prime ministers’ efforts

The Conservative Environment Network, an independent forum for conservatives who support net zero, and others including Greenpeace, are trying to stiffen his spine.

Key Points:

The Conservative Environment Network, an independent forum for conservatives who support net zero, and others including Greenpeace, are trying to stiffen his spine.
But Sunak appears minded to appease those on the “right” who are opposed to anything green.

The UK story

Thanks to switching from coal to gas in the 1990s, and moving industry offshore, the UK could for a long-time boast of reducing its emissions and speak nobly of sustainable development.
In 1997, Tony Blair said the UK would go further in cutting emissions than whatever target was set at the UN conference in Kyoto, the first agreement by rich nations to cut greenhouse gases.
Very few Conservative MPs voted against the 2008 Climate Change Act, which set an 80% reduction in emissions by 2050 and placed restrictions on the amount of greenhouse gases the UK could emit over five-year periods.
After the Paris agreement in 2015, which the UK signed, it became clear that 80% would not be enough of a target to have the UK meet its obligations to do its part to keep global warming under 2℃.

So what’s gone wrong?

They get the glow, without the pain of upsetting either vested interests or demanding that ordinary people change their behaviour.
What we are seeing now, I believe, is a collision between what the promises were and what the immediate action has to be.
But once in power, Conservative governments have tended to prioritise “free markets” over what they label as irksome or socialistic environmental regulation.
