Breaking Waves: Ocean News

During the US time out, Australia and its allies must remain steady and seek to deepen cooperation among themselves The idea of open international exchange that framed the Australian reforms of the late 20th century and its subsequent economic success are being challenged in the 21st century. The challenge is intensified by the restoration of Donald Trump as president of the United States. He is committed to higher protection, tax cuts that will set record highs for budget deficits, a trade war with Australia’s largest trading partner with a risk of worse, and separation of the United States from the rules-based international trading system. He is also committed to withdrawal from international cooperation and domestic action to reduce climate-changing emissions of greenhouse gases. Global financial crisis is not out of the question. These developments will damage Australian interests. Global long-term interest rates set a base against which Australian rates settle, and will be higher than they would otherwise have been. International inflation will be higher, increasing Australia’s own inflation challenge. Australia is the developed country that has most to lose from a failure to stop global heating. Australia has more to gain economically than any other country from success in the world achieving net zero carbon emissions, as an exporter of zero-carbon goods to countries which lack rich renewable energy and biomass resources of their own.

Sir Keir Starmer’s pledge on emissions is an encouraging step at a frightening moment Predictions that this will be the first calendar year in which the 1.5C warming limit enshrined in the Paris agreement is surpassed provide a stark backdrop to the UN’s 29th climate conference. This year – 2024 – has already seen the hottest-ever day and month, and is expected by experts to be the hottest year too. Addressing delegates on Tuesday, the UN chief, António Guterres, referred to a “masterclass in climate destruction”. The escalating pattern of destructive weather events, most recently in Valencia, is a warning of what lies ahead. When the 1.5C figure was included in the 2015 deal, it was known to be a stretch. The treaty says countries must hold the average temperature “well below 2C above pre-industrial levels” and aim for 1.5C. Busting this target in 2024 will not mean it has been definitively missed; the measurement of global temperatures relies on averages recorded over 20 or more years. But the crossing of this threshold is a menacing moment. Around the world, people as well as governments and climate specialists should take notice – and act. Continue reading...

Researchers have found evidence that mangrove forests -- which protect tropical and subtropical coastlines -- are drowning in the Maldives. Their finding indicate that rising sea level and a climate phenomenon known as the Indian Ocean Dipole have led to some Maldivian islands losing over half of their mangrove cover since 2020.

King Felipe VI reportedly plans to revisit Valencia amid alerts for heavy rain, high waves and strong winds People in flood-hit Spain stacked sandbags and braced for new storms on Tuesday as the political repercussions from last month’s deadly climate disaster rumbled on. Amid fresh weather warnings, local media reported that King Felipe VI would soon return to the site of the flash floods, after he was pelted with mud and eggs on his first visit last week owing to local fury at the poor preparation and response of the authorities.
