Summary
Cities face increased heat risks from climate change and urban heat islands (UHI). Urban greening is key to reducing heat and preventing mortality during high temperatures.
Area of Science:
- Environmental Science
- Public Health
- Urban Planning
Background:
- Cities experience heightened heat-related health risks due to the urban heat island (UHI) effect, intensified by global climate change.
- Understanding factors that worsen or lessen heat mortality risk is crucial for urban adaptation strategies.
Purpose of the Study:
- To characterize contextual factors influencing heat-related mortality risk in Paris.
- To identify key elements for effective urban heat adaptation strategies.
Main Methods:
- Analysis of contextual factors contributing to heat-related mortality.
- Characterization of risk exacerbating and attenuating elements in Paris.
Main Results:
- Specific urban factors significantly influence the risk of death during high temperatures.
- Urban greening emerges as a critical factor in mitigating heat impacts.
Conclusions:
- Reducing urban heat and mitigating UHI through greening are essential adaptation strategies.
- Prioritizing urban greening can prevent heat-related health impacts in cities.

01:50Global Climate Change
29.2K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:29Decreased Body Temperature
1.1K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

02:46Quantifying Heat
62.8K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

01:20Hot Weather Concreting
334
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
