Removing salts and other impurities from water is really difficult. For thousands of years people, including Aristotle, tried to make fresh water from sea water.
In cities around the world, trees are often planted to help control temperatures and mitigate the effects of the “urban heat island”. But while trees have been called “nature’s air conditioners”, in practice, scientists often have difficulty demonstrating their cooling properties.
Climate change is already occurring, with impacts that will become more intense for decades into the future.
This summer, wildfires erupted in California, torrential rains flooded parts of Japan, and record-breaking temperatures led to a number of heat-related deaths around the globe. Disasters like these are augmented by climate change, and scientists say extreme weather like this will increase and worsen as climate change accelerates. And it’s impacting our mental health.
Local people collect water from a muddy waterhole in 2006 in San Marcos Tlacoyalco. The Tehuacan Valley South-East of Mexico City has long experienced severe water shortages. Drought and climate change have contributed to this but recent industrial growth has also strained the very limited ground water resource. Water resources in the area are largely based on a weekly delivery by truck as well as collecting water from small pools known as Jagueys.
A more strategic approach to urban growth can ensure our cities maintain adequate green space and become low-carbon, efficient and affordable.
Far from protecting U.S. interests, the tariffs are bound to stifle the current solar boom, destroying American jobs and dragging down clean energy innovation. As economists who research climate and energy policies that can foster a greener North American economy, we argue the government should instead create targeted subsidies that support innovation and lower costs across the supply chain.
You don’t need a supercomputer to predict how the weather above your head is likely to change over the next few hours – this has been known across cultures for millennia. By keeping an eye on the skies above you, and knowing a little about how clouds form, you can predict whether rain is on the way.
Most of us have a range of white goods (refrigerators, washing machines, etc.) in our homes. These white goods provide a host of benefits, but they also have significant environmental impacts, and it’s important to consider these when using and choosing white goods.
To maintain our capacity to address climate change, we need to recognize and address the trauma it creates.
The election of the sixth Labour-led government heralds a new direction for climate change policy in New Zealand. As part of the new government’s 100-day priority plan, it pledged to set a target of carbon neutrality by 2050 and to establish the mechanisms to phase out fossil fuels.
Remember the movie “Moneyball”? The Oakland A’s are struggling, financially and on the baseball field.Then they introduce an innovative system for figuring out which players will improve team performance.
Beef gets a bad press, environmentally speaking. We’re bombarded with reports highlighting its high carbon footprint accompanied by images of belching cows and devastated rainforests.
A 12-year “hurricane drought” during which no major hurricanes formed in the Atlantic ended dramatically in 2017. The devastating impacts of Harvey, Irma, Jose and Maria across the United States and the Caribbean provide tragic reminders of the catastrophic risks we face on our coasts.
A new report indicates that almost half of native California salmon, steelhead, and trout species are on track to be extinct in the next 50 years.
2016-17 has been a great year for Australian farmers, with record production, exports and profits. These records have been driven largely by good weather, in particular a wet winter in 2016, which led to exceptional yields for major crops

African nations have overwhelmingly included climate resilient agriculture in their indicative pledges to the United Nations. And agriculture is seen as a major focus through a common position of the African Union on climate adaptation.
Conversations about climate change often derail into arguments about whether global warming exists, whether climate change is already happening, the extent to which human activity is a cause and which beliefs are based in evidence versus propaganda.
President Donald Trump has the environmental community understandably concerned.
Finding the optimum environment and avoiding uninhabitable conditions has been a challenge faced by species throughout the history of life on Earth.
In 2011, a marine heatwave hit the west coast of Australia leading to ten days of above average sea temperatures.

The soaring temperatures of recent hottest years on record will be the norm by 2040, with Australia first to feel the heat.
Educating rural communities can help them prevent permanent damage to the environment. There is a common misconception that you can’t talk about climate change in rural communities because the issue is considered too polarizing...
People depend on grass crops for food, but new research raises concerns that if climate changes too fast, grasses won’t adapt fast enough to keep pace.
Scientists show how humans can improve poor people’s lives by reversing practices that destroy the environment and fuel climate change.
With every passing year, Southeast Florida faces more pressure to adapt to climate change. The region already experiences the effects of climate change, such as flooding on sunny days during the highest tides of the year
Ecosystems are already showing the signs of climate change, from the recent death of mangrove forests in northern Australia, to the decline in birds in eastern Australia, to the inability of mountain ash forests to recover from frequent fires.
If you flip over a log in a forest in the southeastern U.S., you are likely to find a squirming salamander.
Water crises seem to be everywhere. In Flint, the water might kill us. In Syria, the worst drought in hundreds of years is exacerbating civil war. But plenty of dried-out places aren’t in conflict. For all the hoopla, even California hasn’t run out of water.
Soldiers of the Eco Task Force are playing a key role in forest, soil and water conservation to help India meet emissions reduction targets set at the Paris climate summit.
In a context of unprecedented climate change and food insecurity, adaptation in agricultural systems is critical in Africa. It is crucial to breed new varieties of staple crops that are adapted to deal with climatic conditions.
Scientists have found that some varieties of beans − a vital food crop grown on every continent except Antarctica − have developed ways of coping with the climate-related droughts that threaten them.
In recent years wildfire seasons in the western United States have become so intense that many of us who make our home in dry, fire-prone areas are grappling with how to live with fire.
The plan for Louisville includes tree-planting targets and cool roofing and paving goals for different neighborhoods. In all, an additional 450,000 trees are recommended.
Many regions of the United States are struggling with water shortages. Large areas of the West are contending with moderate to severe drought, while California is now in the fifth year of one of the most extreme droughts in its history. Even non-arid regions, such as the Southeast, are not exempt from water shortages.
Fossil fuel use will have to fall twice as fast as predicted if global warming is to be kept within the 2°C limit agreed internationally as being the point of no return, researchers say.
California has experienced, over the past few years, its most severe drought on record. In response to worsening conditions, Governor Jerry Brown announced the first ever statewide mandatory reduction in urban water use in April 2015. This calls on Californians
It was Charles Darwin, almost 200 years ago, who first asked how it could be that coral reefs could flourish in relatively barren parts of the Pacific Ocean. This conundrum subsequently became known as Darwin’s Paradox.
Scientists say that forecasts of a world food shortage need not prove as disastrous as previously thought if humans learn to use water more effectively.
It’s mid-February and along Britain’s south coast gilt-head bream are drifting from the open sea into the estuaries. Meanwhile, thousands of little egrets are preparing to fly to continental Europe for breeding season, though a few hundred
We don’t have to know exactly how high the sea might rise to start doing something about it.Climate scientists have recently been outraged by job losses within CSIRO. Sixty climate jobs are likely to be lost.
Southern Africa has been experiencing high temperatures in recent months. In October, Zimbabwe experienced a heatwave with temperatures in Kariba reaching 45°C.
Scientists believe they may have found how to safeguard a staple tropical crop, on which hundreds of millions of people depend, from the depredations of climate change. They have discovered − through conventional breeding rather than genetic modification − 30 new “lines” (varieties) of beans that will thrive in the higher temperatures expected later this century.
Florida is a coastal state. Nearly 80% of its 20 million residents live near the coast on land just a few feet above sea level, and over a hundred million tourists visit the beaches and stay in beach-front hotels every year.
Climate change is going to affect every city on the planet in some way—but not necessarily in the same way. For those cities already adapting to it, strong, decisive action may spell the difference between surviving global warming and succumbing to it. Five cities that are steeling themselves…and five that are fooling themselves.
In tropical developing countries, effective coastal management must acknowledge the widespread dependence of poor and politically weak communities on the use of fish for food. Acknowledging this dependence on artisanal fisheries is pivotal to reconciling the largely separate agendas for food security and biodiversity conservation.
Researchers tracking the movements of seals in the North Sea reveal that “artificial reefs” created by wind farms and pipelines are becoming attractive as foraging grounds on fishing expeditions.
I believe we have a problem — a big problem. According to demographers, by the end of this century we’ll have around 11 billion mouths to feed. Most of the additional 4 billion people alive then will be in developing nations.
I recently had the opportunity to engage in conversation with Guy McPherson about a number of topics and subsequently began reading his book Walking Away From Empire, Guy’s personal journey of leaving a tenured professorship to radically alter his living arrangements in preparation for the collapse of industrial civilization.
Dutch scientists have thought up a new use for all the carbon dioxide that pours from the chimneys of fossil fuel-burning power stations: harvest it for even more electricity. They could, they argue, pump the carbon dioxide through water or other liquids and produce a flow of electrons and therefore more electricity.
The world’s coral reefs are under threat. Some scientists say doses of cloud brightening could provide a solution to the problem. Here’s a new twist to the geoengineer’s dilemma: just change the climate locally – over the bit you want to protect – and leave the rest of the planet alone.
Trees may be getting more efficient in the way they manage water. They could be exploiting the higher levels of carbon dioxide in the atmosphere, growing foliage from a lower uptake of groundwater. If so, then the carbon dioxide fertilisation effect – predicted by theorists and observed in laboratory experiments – could be real.
Research into one of the world’s oldest and driest deserts has unearthed evidence of the evolutionary timeline for species that have avoided extinction by adapting to dramatic climate change
Two more US states say they will require insurance companies to reveal how prepared they are to cope with risks related to climate change.
One of the great stumbling blocks of climate talks in the last 15 years has been that America refuses to move to cut emissions of greenhouse gases until China does – but at the weekend leaders of the world’s two great polluters reached agreement to phase out one of the most potent of them hydrofluorocarbons (HCFs).
One of Africa’s most distinguished scientists insists that in a warming climate the world needs to adopt genetically modified crops on a massive scale in order to feed the planet’s growing population.
The good news is that some coral can recover from periodic warming of the oceans: the bad news is it might take too long.
A flagship UN policy designed to help to save the world’s forests faces rejection by indigenous groups in Panama, who believe it is being used in an attempt to usurp their ownership.
As the carbon dioxide in the air hits 400 parts per million for the first time in human history, some are arguing that the best way address climate change is to use the controversial practice of geoengineering — the deliberate altering of the Earth’s ecological and climate systems to counter the effects of global warming.
Solar power is here to stay. So is efficiency and conservative use of electricity. Solar power and local or community production is the best bet for combating global warming. Decentralized and personal production gives home owners and business managers a stake in production and thus conservation.
While many of us are bemoaning the fate of the planet, one man has actually gone out and experimented with solutions to the desertification taking place (grasslands drying out and turning into desert areas) and he has found a solution that works...
Something interesting is happening in Australia. A new study by the research firm Bloomberg New Energy Finance has found that unsubsidized renewable energy is now cheaper than fossil fuels like coal and gas.
