How Seville Stays Cool Despite Rising Heat

Climate change is increasing the average temperatures of cities around the world, which forces inhabitants to adjust to entirely new climates their cities weren’t designed for. In Spain, the city of Seville is expected to have the climate of Marrakesh in a few years time so the city needs to find new ways to cool down. They are currently experimenting with an old technique perfect by ancient people: use water that cools in the night to cool the city during the day.

One of the coolest spots in Seville, Spain, is the site of CartujaQanat, an architectural experiment in cooling solutions that relies not on air conditioning but on natural techniques and materials. Inspired by ancient tunnels dug to bring water to agricultural fields in what is today Iran, the $5.6 million structure uses a network of aqueducts, pipes and solar-powered pumps to cool water at night and then turn it into cold air during the day.

Seville is among the world’s hottest cities looking for new ways to cool down and save lives. Yet despite the project’s early promises, the CartujaQanat remains in limbo amid financial and political hurdles, Laura Millan reports.

Canada Starts to Reduce Oil & Gas Subsidies

A country that loves extracting fossil fuels has begun to clean up its tax rebates for the destructive oil and gas industry. Canada spent over $15 BILLION on subsidies for the oil and gas sector in 2021 alone, which isn’t just bad it’s literally funding the destruction of the planet. Thankfully the government has figured out that destroying the land for short term profit isn’t a good idea when the industry profiting kills everything it touches.

Starting this year the Canadian government will begin the long process of cutting tax loopholes and subsidies for oil and gas, which generate billions in profits. Why fund an industry that is insanely profitable that harms people and the planet?

Burning fossil fuels is one of the main drivers of climate change, so ending public spending that supports the industry is crucial. Ending fossil fuel subsidies frees up those funds to support things like renewable energy and electrification. Clean energy is of paramount importance as the world is under pressure to slash greenhouse gas emissions more than 40 per cent by the end of the decade.

“Moving forward, every subsidy that the government would want to grant to the oil and gas sector would have to go through this filter — any department of the federal government, whether it’s finance, international trade, natural resources — to ensure that we do not give federal dollars to support the production of oil and gas or coal,” said Guilbeault. “This is a fundamental shift from what we’ve done in this country for decades.”

Working Out Helps You Work it Out

Going for a walk can help you settle down your overactive brain and help you see things positively, and best of all it’s free! Anxiety and depression rates are increasing in North America for a variety of legitimate reasons; however, we a little working out can bring those rates down. A very effective treatment for anxiety and depression is to use your body and workout. There’s no a growing movement in the english speaking world to get medical professionals prescribe exercise as part of a treatment plan.

“Physical activity can be an effective treatment for mental health problems,” says Ben Singh, lead author and research fellow at the University of South Australia. He thinks it works in several ways: by releasing endorphins and boosting our mood, improving sleep, reducing stress, supporting self-esteem and confidence, and making us feel accomplished and purposeful.

The findings suggest that exercise is particularly helpful in certain situations. While the type of exercise didn’t matter, people got more mental health benefits out of higher-intensity exercise. If you’re doing something that makes you breathe hard, in other words, that’s a good sign.

Transit Hub Addiction Clinics Benefit Everyone

When social services are difficult to get to then their services are used less, it sounds obvious but in too many places social services are very difficult to get to. Car centric urban designs further exacerbate inequality by limiting mobility options, or to put it another way: cars limit freedom of access and opportunities.

In order to best help everyone in our communities we should ensure that social services are accessible and what better way than at transit hubs? Many people suffering from addiction also suffer from economic problems so ensuring that they can easily get to treatment centres can help them recover. Early research is proving that accessible treatment centres help everyone.

“What we’re finding is that there’s this significant relationship between being close to these new transit start ups … and costs, operating costs are significantly less,” said Cohen.

“The other thing that we’re finding is that there’s a relationship between equity and access to treatment.”

The research looked at addiction and mental-health clinics that were within half-a-mile, or approximately 800 metres, of a new transit route. Cohen considered that basically walking distance, and compared results with those from clinics further afield.

Save the Seabirds, Save the World

Seabirds like the puffin are cute and curious things, and it turns out that if we help them thrive we can help the carbon cycle. Habitats that are good for seabirds can sequester carbon efficiently and due to the level of nutrients can provide energy for other lifeforms. The key for seabirds is their colony size, right now they are tiny and spirited; instead, by getting colonies to be in the same area the benefits are exponential due to more robust biodiversity.

Restoring seabirds could bolster ocean ecosystems and their ability to draw down carbon dioxide, said Hans-Otto Pörtner, a climate scientist at the Alfred Wegener Institute in Germany, who recently co-authored a research paper in Science that spells out the the connections between biodiversity, ecosystem protection and climate stabilization.

In addition to direct CO2 emissions from burning fossil fuels and other industrial processes, the disruption of ecosystems and biodiversity declines have also significantly contributed to rising atmospheric greenhouse concentrations that are heating up the planet, he said.

“Biodiversity loss contributes to climate change through loss of wild species and biomass,” the paper concluded. “This reduces carbon stocks and sink capacity in natural and managed ecosystems, increasing emissions.”
