New pesticides may harm bees as much as existing ones – study

Guardian Environment News - Wed, 2018/08/15 - 5:02pm

Ability of bumblebees to reproduce, and rate at which colonies grow, compromised by new sulfoximine-based insecticides

A new class of pesticides positioned to replace neonicotinoids may be just as harmful to crop-pollinating bees, researchers have warned.

In experiments, the ability of bumblebees to reproduce, and the rate at which their colonies grow, were both compromised by the new sulfoximine-based insecticides, they reported in the journal Nature.

Sea life in 'peril' as ocean temperatures hit all-time high in San Diego

Guardian Environment News - Wed, 2018/08/15 - 12:51pm

Between 1982 and 2016, the number of ‘marine heatwaves’ doubled, and likely will become more common and intense as the planet warms, study finds

Even the oceans are breaking temperature records in this summer of heatwaves. Off the California coast near San Diego, scientists in early August recorded all-time high seawater temperatures since daily measurements began in 1916.

“Just like we have heatwaves on land, we also have heatwaves in the ocean,” said Art Miller of the Scripps Institution of Oceanography.

Humans are pushing the Earth closer to a climate cliff | John Abraham

Guardian Environment News - Wed, 2018/08/15 - 3:00am

A new study examines potential climate feedbacks that could push Earth into a ‘hothouse’ state

A new paper, just published in the Proceedings of the National Academy of Sciences has received a lot of media attention. The attention is justified because the paper paints a very grim picture of the climate and what humans may be doing to it. In particular, the authors of this study tried to determine the trajectory that the Earth is on so we can predict what the future climate will be.

There are many really important insights from this paper. The authors wanted to know how feedbacks in the Earth’s climate will play a role in shaping the climate in the future. By feedbacks, we mean a change in one part of the climate that then causes another change, which in turn may cause another change, and so on, potentially setting up chain reactions.

Nutria: the rodent wreaking havoc on California's landscape – video

Guardian Environment News - Wed, 2018/08/15 - 2:25am

The rapid influx of these beaver-like rodents has decimated parts of the Californian wetlands. They were introduced to the US for the fur trade and now share wetland areas with some of the west coast’s most endangered species. The California department of fish and wildlife has compared the threat of their presence to that of wildfires

California v nutria: state seeks to eradicate scourge of giant rodents

Sanjeev Gupta: $1bn South Australia renewable energy plan will mean cheaper power

Guardian Environment News - Tue, 2018/08/14 - 10:21pm

UK industrialist’s plan features 780,000 solar panels, generating enough electricity for 96,000 homes

Billionaire UK industrialist Sanjeev Gupta has launched a $1bn, one-gigawatt renewable energy plan based in South Australia’s mid-north that he says will lead Australian industry’s transition to more competitive power.

In the first of a number of projects slated for the upper Spencer Gulf region, which will also include a lithium-ion battery bigger than Elon Musk’s, Gupta’s energy company Simec Zen has released details of its Cultana Solar Farm.

time for a new torch

The Field Lab - Tue, 2018/08/14 - 3:40pm

My Bernzomatic TS8000 is finally shitting the bed after melting almost 200 ounces of silver over the past 3 years.  First the trigger lock went out and now it can't keep a nice high temperature flow.  Was trying to do a test casting today for some crosses that have been ordered and ended up with an ounce and a half of silver stuck in my ceramic crucible.  A replacement torch is coming tomorrow and the good news is it was 25 bucks cheaper than when I got the first one in 2015.  84,90,68,0,C

Claimed power price cuts from energy guarantee are 'virtually meaningless'

Guardian Environment News - Tue, 2018/08/14 - 11:00am

Coal-fired power subsidies mean the projections relied on by Coalition are not credible, study says

The Turnbull government is trumpeting power price reductions as a consequence of its national energy guarantee – but a new analysis says subsidies for coal-fired power stations will render those forecasts “virtually meaningless”.

The government has failed to rule out the building of new coal plants as a consequence of its underwriting of new power generation, and Labor declaring that development a deal breaker.

Calls for environmental water entitlements to be sold to drought-affected farmers

Guardian Environment News - Tue, 2018/08/14 - 11:00am

Politicians and farmers say water should be diverted to crops to keep herds alive

There are growing calls for the federal and state governments to start selling government-owned environmental water entitlements to farmers to alleviate the drought and to keep livestock alive.

But the proposals would see wetlands and river courses starved of water with potential environmental stress from the drought exacerbated by the diversion of water onto farmland.

Stop climate change, don’t ‘adapt’ to it | Letters:

Guardian Environment News - Tue, 2018/08/14 - 10:04am
Judy Hindley says we must increase the price of fossil fuels, and Iain Climie raises the issue of climate change refugees

While I appreciate your work in keeping the spotlight on the global heatwave (World on fire: the rise of the 50C city, G2, 13 August), I’m scared by the emphasis of your correspondents and leader writers on “adapting” to climate change (Letters, 11 July). You don’t “adapt” to a raging fire, do you? You have to stop it. And the first thing you need to do is stop pouring fuel on it.

Leading scientists worldwide now agree that the main cause of the climate crisis is the burning of fossil fuels, and leading economists agree that the solution is to price fossil fuels out of the market. Until that happens, we will be paying – with our health, our lives and our children’s future.

Extreme temperatures 'especially likely for next four years'

Guardian Environment News - Tue, 2018/08/14 - 8:00am

Cyclical natural phenomena that affect planet’s climate will amplify effect of manmade global warming, scientists warn

The world is likely to see more extreme temperatures in the coming four years as natural warming reinforces manmade climate change, according to a new global forecasting system.

Following a summer of heatwaves and forest fires in the northern hemisphere, the study in the journal Nature Communications suggests there will be little respite for the planet until at least 2022, and possibly not even then.
