Symonds Yat Rock, Forest of Dean This is an old world forest; organic, unwieldly, fecund, oaky – forest as nature wanted

Summer’s end, and the forest is thick. Beneath the leaves, the sun creates puddles of bright and black, through a canopy still swollen enough to block most of its light. Roads are green tunnels. Paths are dark and have a warm smell, the dense flotilla-dust of bug, web and sap lit brilliantly in the air. Soon the forest leaves will burn, through every shade of russet, to glorious autumnal death.

The Forest of Dean is an old world forest; organic, unwieldy, fecund, oaky. Forest as nature wanted, not the sterile, shadowed ranks of spruce that too often masquerade as such. In high summer a walk under the canopy seduces, in autumn one through its fresh decay beguiles. But now the more subtle charms of September’s change-month call for a higher lookout.

It's remarkable how quickly a national conversation can fall into the gutter of bipartisanship and ignorance. But the legacy could be damaging: dumb politics could leave Australia with an even dumber grid.

13 game-changing initiatives from around the world were announced today as winners of the United Nations ‘Momentum for Change’ climate change award.

Turnbull amongst many to point the finger at renewables for South Australia's power outage. What else can we blame renewables for? Twitter answers.

The Lyon Group announces a partnership with Mitsubishi Corporation to roll out 1GW of solar and up to 1GWh of battery storage by 2020.

Australian academics give their views on how to constrain fossil fuel supply as part of efforts to tackle climate change.

New DOE report details latest advances in solar, wind, LED lights, batteries, and electric cars.

Labor states accuse Turnbull of peddling "ignorant rubbish"about wind and solar in the wake of the South Australian blackout.

ABC's Chris Uhlmann doubles down on attacks on renewable energy by predicting the whole nation is at risk of a blackout if we pursue wind and solar. Doesn't the ABC have editors?

Safeguards to the UK's domestic marine life should be as strong as they are around Britain’s overseas territories, conservationists say.

Female snakes, hungry after waiting for their eggs to hatch, are heading indoors in search of food such as rats

A shortage of volunteer snake-handlers is starting to bite in north Queensland, where an end-of-breeding-season influx of hungry reptiles into homes is driving an increase in the number of calls for help.

The need for sustenance by female snakes that have shed weight while waiting for their eggs to hatch has driven them indoors in search of food, including rats.

How much time do you spend thinking about cyber security? Probably not as much as you should. We are all vulnerable to attack, and as the internet becomes more pervasive, the threat is growing

When a 20-year-old hacker broke into US vice-presidential candidate Sarah Palin’s Yahoo email account during the 2008 presidential campaign, it didn’t take a great deal of computer expertise.

“The hacker simply used the password reset prompt and answered the secret questions,” says Dr Nalin Gamagedara Arachchilage, a lecturer in cyber security at the Australian Centre for Cyber Security, part of the University of New South Wales, based at the Australian Defence Force Academy in Canberra.

Superintendent Don Neubacher, who is accused of publicly ‘humiliating’ and intimidating workers, stepped down as California park faces misconduct scandal

The head of Yosemite national park is stepping down in the wake of reports of “horrific working conditions” and rampant sexual harassment, the latest in a controversy that has brought national shame to one of America’s most beloved landmarks.

Superintendent Don Neubacher, who is accused of publicly “humiliating” and intimidating workers, said in an email to staff that he “regrets” leaving but wanted to “do what’s best” for the popular California park that has faced a widening misconduct scandal in recent months.

Exclusive: bank turns down owners’ application for $500,000 bridging loan on grounds that Queensland property has four coal seam gas wells on it

Australia’s biggest mortgage provider has declared a Queensland property with coal seam gas wells “unacceptable” as security for residential lending, raising fresh concerns that people living in the state’s gasfields may be unable to sell their homes.

But Queensland Gas Company (QGC), which owns the wells on the Chinchilla acreage, has insisted that no properties that host its infrastructure have had their values negatively affected.

Climate Council member Andrew Stock says political conflict over renewables risks their future in Australia.

Science editor David Shukman goes on board the plane measuring the jet stream to find out how it affects our weather.

The Rosetta probe, which has been beaming back spectacular pictures of a comet, is to end its journey by crash landing.

Most painted ladies have already headed south, and new research reveals just how far these butterflies travel

The last red admirals and commas are feeding on ivy flowers in autumn sunshine and Britain’s butterfly year is drawing to a close once more.

One butterfly, though, is on the move. I’ve seen several painted ladies this month, but most have already headed south for the winter. The fate of British-born generations of painted ladies was a mystery until recently, when radar finally documented how they ascend to great heights before beginning their reverse migration.

Apple bud in flower Martine Combret

As the weather warms and days lengthen, your attention may be turning to that forgotten patch of your backyard. This week we’ve asked our experts to share the science behind gardening. So grab a trowel and your green thumbs, and dig in.

Spring arrives and the warming weather encourages the plants in our gardens and parks to burst into life, commencing their annual reproductive cycle.

Plants use cues from the weather and climate to time their growth, flowering and fruiting. But as the world heats up due to climate change, these patterns are changing.

So how is climate change affecting our gardens, and what can we do about it?

In sync with climate

Many temperate plants have evolved to reproduce in spring to avoid damage from extreme cold or heat. Warmer conditions tend to speed up these processes, causing plants to grow faster.

Plants have evolved sophisticated mechanisms to synchronise with climate. This means they are excellent bio-indicators of climate change.

We know from global assessments that most plants studied so far are behaving as we’d expect them to in a warming world. Studies in the Southern Hemisphere have found the same.

In Australia, plants in southern Australia are maturing earlier – winegrapes, for instance, by 27 days on average between 1999 and 2007. We can see this in wine growers’ records. As you can see in the handwritten chart below, wine grapes are on average maturing (measured by their sugar content) earlier.

Other plants may behave differently. Fruit trees such as apples need cold weather to break buds from their dormant state, before commencing growth when warm temperatures arrive.

This means after warm winters, such as this one, flowering may actually be delayed. Data from a recent study show potentially delayed flowering for Pink Lady® apples, as you can see below.

In the examples above, Applethorpe had the warmest spring and flowered first, as we’d expect for most plants. But Manjimup had the second-warmest spring and flowered last, even after Huon, the coldest spring site. This seems counter-intuitive but the delay is likely because Manjimup had the warmest winter.

Do these changes matter?

The earlier emergence of reproductive tissues may increase the risk of devastating frost damage. Contrary to what you might expect, evidence shows recent warming in southern Australia has not necessarily led to fewer frosts. On the other hand, plants that delay flowering because of warmer winters may reduce their frost risk.

Shifts in flowering timing, earlier or later, can be problematic for plants that rely on pollination between different varieties. Both varieties must shift flowering in the same way for flowering periods to overlap. If flowering times don’t overlap, pollination will be less successful, producing fewer fruit.

Bee and bird pollinators must also adjust their activity in sync with changes to flowering time to facilitate pollination.

Faster maturity may shift ripening into hotter times of year, as seen for wine grapes. This increases the risk of extreme heat damage.

Pests and diseases will also adjust their growth cycles in response to a changing climate. One pest well known to gardeners is the Queensland Fruit Fly (QFF). Their maggots are found in a wide range of fruits.

Climate change will likely favour fruit flies. Warmer temperatures for longer periods will encourage a higher number of generations each year. Meanwhile, reduced cold weather will mean fewer fruit flies will die, increasing the flies’ survival rates.

On the other hand, temperate pests and diseases may decrease if warming exceeds their temperature thresholds.

What can you do?

What have you observed? Citizen scientists who track the timing of biological events have provided valuable information, especially in Australia, for us to monitor and interpret plant responses to climate change. Keeping garden records will show if and how your plants or pests are changing their patterns.

If you observe your flowers emerging earlier, coverings can be used to protect against frost. Keep an eye on cross-pollinators – are they flowering together? If not, consider planting a different cross-pollinator.

Nets are an effective way to reduce heat damage and can also be used to protect against some pests. Setting pest traps according to weather rather than the calendar will help disrupt the first generation and reduce pest impact.

Climate change has already influenced biological responses, perhaps even in your own garden. Seeing these changes in our gardens gives us an insight into the significant challenges faced by our food production systems under a changing climate.

Adapting to current and future climate change is a reality, and is essential to preserve both the enjoyment we experience in our own gardens and the security of future food supply.
