Heat rectification via suspended asymmetric graphene nanomesh
It is one of the humans' desired goals that we want to precisely control the heat transport as the level as that we can control the electrical current. However, a high-performance thermal rectifier or thermal diode is still missing. Currently, resear.....»»
Plant thermogenesis has played key role in attracting pollinating insects for at least 200 million years, study suggests
Thermogenesis is a process by which organisms generate internal heat. Although it is usually associated with animals, some plants have also developed this ability. This metabolic process allows certain parts of the plant, such as flowers and inflores.....»»
Dangerous heat wave intensifies in US Southwest
A punishing heat wave gripping California and parts of the southwestern United States was intensifying Thursday as forecasters warned of dangerous temperatures......»»
Adding an alternating magnetic field to layers of twisted graphene creates even more exotic properties
Magnetic fields can engineer flat bands in twisted graphene layers to create a new playground for exotic physics, RIKEN physicists have shown......»»
Chinese cities suspend schools, cancel flights ahead of super typhoon Yagi

Heat waves and droughts cause billions of dollars in global economic losses, research finds
Severe weather costs the global economy billions of dollars a year, highlighting the costs of climate change and the value of mitigating extreme weather, according to a new analysis of weather and economic data......»»
NASA mission gets its first snapshot of polar heat emissions
NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experim.....»»
Five lessons from ancient civilizations for keeping homes cool in hot, dry climates
Modern buildings tend to take electricity and air conditioning for granted. They often have glass facades and windows that can't be opened. And when the power goes out for days in the middle of a heat wave, as the Houston area experienced in July 202.....»»
Global South cities lack cooling green spaces
Cities in the Global South are more exposed to extreme heat because they lack cooling green spaces, new research shows. The study found that Global South cities have just 70% of the "cooling capacity" provided by urban greenery in the Global North. T.....»»
Study finds lower-income NYC residents trade comfort for affordability
In a revealing piece of research coauthored by a Singapore Management University academic, public policies to ease urban heat in one of the largest first world cities have seen price gaps emerge between homes in cooler and hotter areas, with lower-in.....»»
Study reveals key strategies to combat urban heat vulnerability
A QUT study analyzing five decades of research and thousands of studies has identified five critical areas needed to tackle urban heat vulnerability (UHV), a growing issue impacting millions in increasingly heat-prone cities......»»
Air conditioning poses a climate conundrum
This week, much of the US is suffering from yet another heat wave. So far this year, 15 countries have set records for high heat. Last July, the average global temperature, factoring in heat waves in multiple regions around the world, was likely the.....»»
Ocean heat is changing marine food webs—with far-reaching consequences for NZ fisheries and sea life
The global ocean continues to warm at a concerning rate......»»
Arctic heat waves linked to sea ice loss, new study reveals
Amid global warming, heat waves are striking even the Arctic, a region once considered immune to such extreme weather events. Recent research reveals that these heat waves, particularly in the Barents-Kara Sea (BKS) during the boreal autumn, are not.....»»
People in Brazil"s Amazon are choking on smoke and feeling the heat from rainforest wildfires
Smoke from wildfires in Brazil's Amazon rainforest Wednesday was causing people in the region to cough, burning their throats and reddening their eyes......»»
During a heat wave, "stay indoors" can bring hazards, too
With Chicago and much of the Midwest facing what may be the hottest days of the summer this week, many are cranking up the air conditioning and heeding the advice of officials to stay inside......»»
Authors propose multi-method framework for climate event attribution
At the two most recent meetings of the United Nations Framework Convention on Climate Change, delegates agreed to establish a fund to help developing nations suffering loss and damage due to events linked to climate change, such as floods, heat waves.....»»
International report confirms record-high global temperatures in 2023
Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level, and ocean heat content all reached record highs in 2023, according to the 34th annual State of the Climate report......»»
The Quantum Mechanics of the Greenhouse Effect
Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model......»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
