The federal parliament has voted to funnel A$200 million to drought-stricken areas. What exactly this money will be spent on is still under consideration, but the majority will go to rural, inland communities.
Heat waves can be deadly, especially when they combine high temperatures with elevated humidity levels that make the air feel even hotter. The impacts can be especially strong in cities, which often are several degrees warmer than nearby rural areas due to the urban heat island effect. These three articles from The Conversation’s archives describe steps that communities can take to adapt as climate change makes heat waves more frequent and intense.
Former Australian Greens leader Bob Brown made headlines this week after he objected to a proposed wind farm on Tasmania’s Robbins Island. The development would see 200 towers built, each standing 270 meters from base to the tip of their blades.
A record start to summer ice melt in Greenland this year has drawn attention to the northern ice sheet. We will have to wait to see if 2019 continues to break ice-melt records, but in the rapidly warming Arctic the long-term trends of ice loss are clear.
Earth’s magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source of this magnetic field is the core at the center of our planet.
Restoring the world’s forests on an unprecedented scale is “the best climate change solution available”, according to a new study. The researchers claim that covering 900m hectares of land – roughly the size of the continental US – with trees could store up to 205 billion tonnes of carbon, about two thirds of the carbon that humans have already put into the atmosphere.
Between the scientific community, governments, humanitarian organizations, and even military planners, climate change is considered to be the single greatest threat facing humanity today. Between the increases in famine, disease, flooding, displacement, extreme weather, and chaos that result, it is clear that the way we are causing our planet to get warmer is having dire consequences.
The green belt of tropical rainforests that covers equatorial regions of the Americas, Africa, Indonesia and Southeast Asia is turning brown. Since 1990, Indonesia has lost 50% of its original forest, the Amazon 30% and Central Africa 14%. Fires, logging, hunting, road building and fragmentation have heavily damaged more than 30% of those that remain.
Late on Monday night, the City of Sydney became the first state capital in Australia to officially declare a climate emergency. With climate change considered a threat to human life, Sydney councillors unanimously supported a motion put forward by Lord Mayor Clover Moore to mobilise city resources to reduce carbon emissions and minimise the impact of future change.
Coral reefs are home to so many species that they often are called “the rainforests of the seas.” Today they face a daunting range of threats, including ocean warming and acidification, overfishing and pollution. Worldwide, more than one-third of all coral species are at risk of extinction.
The island of Santorini in the Mediterranean has attracted people for millennia. Today, it feels magical to watch the sun set from cliffs over the deep bay, surrounded by cobalt blue churches and whitewashed houses. This mystical place attracts about 2 million tourists per year, making it one of the top destinations in Greece.
Burning trash has a long history in the United States, and municipal solid waste incinerators have sparked resistance in many places. As an environmental justice scholar who works directly with low-income and communities of color, I see incineration as a poor waste management option.
The big problem with plastics is that though they last for a very long time, most are thrown away after only one use. Since plastics were invented in the 1950s, about 8,300 million metric tonnes (Mt) have been made, but over half (4,900 Mt) is already in landfill or has been lost to the environment. In 2010 alone, an estimated 4.8 to 12.7 Mt went into the oceans.
The annual World Oceans day is upon us. If we really want to do something about the effect of additional CO2 emissions on climate change we have to look at the oceans according to marine geologist, Professor Gert-Jan Reichart from the Royal Netherlands Institute for Sea Research and Utrecht University.
The news is grim: According to a report compiled by hundreds of scientists from 50 countries, Earth is losing species faster than at any other time in human history. Thanks to climate change, coastal development and the impacts of activities such as logging, farming and fishing, roughly 1 million plants and animals are facing extinction.
We are pretty sure the continental parts of plates are not uniform, nor are they rigid. The giant forces that slowly move continents across the viscous mantle layer underneath, like biscuits gliding over a warm toffee ocean, stress the continents, and twist and contort the crust. This is a process that has taken place over millions of years.
By oxidizing methane and converting it to methanol, methanotrophic bacteria (or “methanotrophs”) can pack a one-two punch. Not only are they removing a harmful greenhouse gas from the environment, they are also generating a readily usable, sustainable fuel for automobiles, electricity and more.
You need only look to the UK’s high streets to see myriad buildings in decline. Walk through any city or town and witness the empty shops, vacant office blocks and derelict housing. A recent report from the Royal Society for Public Health revealed that one in 10 high street shops in the UK is empty.
Whenever I visit the Sahara I am struck by how sunny and hot it is and how clear the sky can be. Aside from a few oases there is little vegetation, and most of the world’s largest desert is covered with rocks, sand and sand dunes. The Saharan sun is powerful enough to provide Earth with significant solar energy.
Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.
Only seven months after NASA's Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world's largest island, an OMG crew is back in Greenland to collect more data. With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland's melting glaciers affects them. All that data has answered a lot of existing questions — and it's raised plenty of new ones.
On the long-running television series Star Trek, the characters were knowledge workers and did not seem to worry about food, lodging or acceptance. Theirs was an inclusive society, one that collaboratively practised sustainable innovation.
