The $270 million battle to save an iconic London bridge from falling into the River Thames

For hundreds of years, they have worked tirelessly to carry the load of one of the world's busiest cities. Key points: Hammersmith Bridge has been shut to cars since April 2019 and to pedestrians and cyclists since August 2020The bridge was shut due to the danger of it collapsing, and will require a $270 million renovation to reopenAn increase in traffic and the effects of climate change are putting added pressure on all of London's bridges But many of the 35 bridges that span the Thames were originally built to carry horse and cart, and the strain of modern-day traffic is taking its toll. The magnificent Hammersmith Bridge is a case in point.

The bridge is nothing short of a Victorian-era masterpiece. For more than 130 years it has withstood all that has been thrown at it, but breaking point came after a particularly warm summer saw large cracks worsen.

The potential for seaweed to reduce methane emissions in sheep and cattle is being overblown and investors are at risk, according to one of the nation's leading experts on seaweed.

Is asparagopsis seaweed a key way to reduce methane emissions in sheep and cattle, or a risky investment?

Key points: The CSIRO claims an asparagosis additive will reduce emissions caused by burping sheep and cattleMarine ecologist Dr Pia Winberg says the hype reminds her of the failed investment boom in algal biofuelsA Tasmanian dairy farmer is feeding some of his herd a daily ration of asparagopsis in canola oil Dr Pia Winberg is a world-renowned marine ecologist, who has developed Australia's first commercial seaweed farm on the south coast of New South Wales. Australia's peak scientific agency CSIRO discovered the methane-reducing properties of asparagopsis seaweed, and claims its FutureFeed additive will reduce the near 10 per cent of Australian emissions caused by burping sheep and cattle.

FOI documents show Darwin's $2.7m shade structure reduces heat by less than 1C. A $2.7 million government-funded shade structure in Darwin's CBD has cooled temperatures underneath it by less than 1 degree Celsius in the two years since it was built, documents obtained by the ABC reveal.

An $80,000 study assessing the shade structure's effectiveness has been obtained through FOIData from mid-2020 shows it reduced average peak heat by 2 per cent, from 32.1C to 31.4CResearchers say the structure's cooling performance will improve once the vines are fully grown The 55-metre structure on Cavenagh Street was completed in late 2018 as part of the NT Government's plan to transform Darwin into "a cool, tropical, world-renowned destination", after a 2017 heat study revealed some surfaces in the city were hitting temperatures between 45C and 67C.

Labor set for climate change shift with architect of emissions target Mark Butler to go. As heatwaves become more extreme, which jobs are riskiest? Heat is more dangerous than the cold in most Australian regions.

About 2 per cent of deaths in Australia between 2006 and 2017 were associated with the heat, and the estimate increases to more than 4 per cent in the northern and central parts of the country. The risk is higher in some regions but where you live is not the only factor that matters. When it comes to heat, some jobs are much more dangerous, and put workers at higher risk of injury.

How to make your home more resilient to heatwaves and severe storms in summer - Science. Some parts of Australia are sweltering as a heatwave moves from Adelaide across to the east coast.

The City of Churches is no stranger to heatwaves. In February 2017, the city experienced temperatures above 40 degrees Celsius for three consecutive days. At night, temperatures didn't drop below 30 degrees. Michelle Leishman and colleagues at Macquarie University analysed images collected during the heatwave as part of a heat-mapping project of West Adelaide. Heatwaves may mean Sydney is too hot for people to live in 'within decades'
