Heat waves and winter storms combined with power outages are a dangerous recipe that can have tragic results.
Extreme weather-induced power outages mean sweltering under relentless heat or freezing temperatures with no power to operate an air conditioner or heater.
Texas, for example, has its own non-profit operated grid called ERCOT, so when much of the state saw its hottest July on record in 2022, officials there issued what’s called a conservation appeal asking the public to reduce energy consumption during periods of extreme heat. This came on the heels of a power crisis in 2021 in the same state when a brutal winter storm crippled wind turbines and natural gas infrastructure that weren’t adequately winterized. Gas-fueled power plants in Texas went down as a result, leaving millions cold and in the dark.
Outages caused by winter storms and summer heat waves can leave residents powerless, but they’re fundamentally different problems with essentially opposite solutions. Winter outages typically stem from a large or sudden drop in the supply of energy to the grid. A natural gas power plant goes offline, turbines stop turning or a snow-loaded tree falls onto a power line, cutting off service.

Blackouts during a heat wave, on the other hand, are usually triggered by an excess in demand for electricity. They’re typically caused by thousands of households all turning on their air conditioners at the same time to escape the heat. This is why utilities and other officials will often appeal to customers to conserve energy when the mercury rises.
Such energy conservation appeals help prevent blackouts, said Yami Newell, associate director for community projects at Elevate, a Chicago-based non-profit that works on energy issues. But it can also lead to some hard choices for people who are left to figure out how to reduce their own energy consumption.
Newell emphasized that reducing your energy consumption doesn’t have to mean just sweating and suffering through it.

Invest in a back-up source of power like a generator or battery system. There are a wide array of backup power solutions on the market, from whole home gas-powered generators costing tens of thousands of dollars, to inexpensive portable batteries you can charge off a wall socket beforehand to provide several hours of power for essential devices when the power goes out. More on these options in the next section.
Consider an electricity-free source of heat like a wood stove. There are also a limited amount of gas or propane heaters that can be operated safely indoors. If you opt for such a source of heat, ensure that you follow all instructions for operating such a heater safely to avoid starting a fire or carbon monoxide poisoning.
Stock up on supplies. If you don’t have a back-up source of power, or even if you do, it’s a good idea to keep a sufficient amount of food, blankets, water, warm clothing (dress in layers), batteries and light sources (careful with candles) on hand.
Weatherize your house before the storm hits. If your home is of a certain age, there’s a good chance it’s leaking warmth somewhere. Sealing those leaks and adding insulation will keep you warmer a little bit longer when your heat goes out. These improvements also qualify for a federal tax credit.
How to protect yourself from power outages
One way to never worry about power outages is to set up your own energy generation and storage system. This can be done in the form of solar panels and battery storage, which comes with the added benefit of being able to sell the extra power you generate to your local utility in exchange for credits on your monthly bill.
Other homeowners go for the arguably simpler approach of installing a back-up generator that can kick on to run your house when the grid goes down. You can also buy back-up batteries that you can charge via the grid or however you like to use in an emergency, rather than a generator that can be loud and uses fossil fuels. This is typically the least expensive option, but needs to be charged in advance of the emergency and only lasts for a few hours or days at most, depending on usage.
According to the New York Daily News, increased energy consumption during a heat wave in New York this past August caused feeder cables to need repair. These Con Edison field operators are trying to prevent a blackout as they work towards fixing them.

How reducing your energy use can help the grid
The stability of an electrical grid, and really any electrical system, depends on being able to maintain a steady supply of energy to meet the demand of devices that are pulling from or consuming the energy.
This is why things can go haywire in your home if you plug too many things into a single circuit that isn’t designed to handle that much demand. Circuit breakers in your home are actually set to shut off the flow of power in the circuit when this happens to prevent damage to your devices or electrical system.
Something similar can happen to the larger electrical grid when heat waves hit and thousands of energy-hungry air conditioners are all turned on at once. If demand begins to approach a state of exceeding the available supply of electricity on the grid, the utility must initiate rolling blackouts to prevent damage to the system. If preventive measures aren’t implemented in time and the system overloads and causes an unplanned blackout, the lights may stay off for even longer until damaged components can be repaired or replaced.
Running several electric heaters in a large room on a cold winter day might trip a breaker in your home in the same way that a heat wave-induced power demand might trigger a broader blackout.
Employing passive cooling techniques, like simply drawing light-colored curtains during sunny hours can reduce temperatures in your home and your energy usage as well. Even taking simple measures that reduce ambient temperatures by just a few degrees translates to less energy usage.
All of these tips and actions may look like small measures that have no effect on your energy grid, but if enough people take steps towards energy conservation during extreme weather events, it could help make a bigger impact.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

The European Space Agency is fast-tracking a new mission called Ramses, which will fly to near-Earth asteroid 99942 Apophis and join the space rock in 2029 when it comes very close to our planet — closer even than the region where geosynchronous satellites sit.
Ramses is short for Rapid Apophis Mission for Space Safety and, as its name suggests, is the next phase in humanity’s efforts to learn more about near-Earth asteroids (NEOs) and how we might deflect them should one ever be discovered on a collision course with planet Earth.
In order to launch in time to rendezvous with Apophis in February 2029, scientists at the European Space Agency have been given permission to start planning Ramses even before the multinational space agency officially adopts the mission. The sanctioning and appropriation of funding for the Ramses mission will hopefully take place at ESA’s Ministerial Council meeting (involving representatives from each of ESA’s member states) in November of 2025. To arrive at Apophis in February 2029, launch would have to take place in April 2028, the agency says.
This is a big deal because large asteroids don’t come this close to Earth very often. It is thus scientifically precious that, on April 13, 2029, Apophis will pass within 19,794 miles (31,860 kilometers) of Earth. For comparison, geosynchronous orbit is 22,236 miles (35,786 km) above Earth’s surface. Such close fly-bys by asteroids hundreds of meters across (Apophis is about 1,230 feet, or 375 meters, across) only occur on average once every 5,000 to 10,000 years. Miss this one, and we’ve got a long time to wait for the next.
When Apophis was discovered in 2004, it was for a short time the most dangerous asteroid known, being classified as having the potential to impact with Earth possibly in 2029, 2036, or 2068. Should an asteroid of its size strike Earth, it could gouge out a crater several kilometers across and devastate a country with shock waves, flash heating and earth tremors. If it crashed down in the ocean, it could send a towering tsunami to devastate coastlines in multiple countries.
Over time, as our knowledge of Apophis’ orbit became more refined, however, the risk of impact greatly went down. Radar observations of the asteroid in March of 2021 reduced the uncertainty in Apophis’ orbit from hundreds of kilometers to just a few kilometers, finally removing any lingering worries about an impact — at least for the next 100 years. (Beyond 100 years, asteroid orbits can become too unpredictable to plot with any accuracy, but there’s currently no suggestion that an impact will occur after 100 years.) So, Earth is expected to be perfectly safe in 2029 when Apophis comes through. Still, scientists want to see how Apophis responds by coming so close to Earth and entering our planet’s gravitational field.

“There is still so much we have yet to learn about asteroids but, until now, we have had to travel deep into the solar system to study them and perform experiments ourselves to interact with their surface,” said Patrick Michel, who is the Director of Research at CNRS at Observatoire de la Côte d’Azur in Nice, France, in a statement. “Nature is bringing one to us and conducting the experiment itself. All we need to do is watch as Apophis is stretched and squeezed by strong tidal forces that may trigger landslides and other disturbances and reveal new material from beneath the surface.”

By arriving at Apophis before the asteroid’s close encounter with Earth, and sticking with it throughout the flyby and beyond, Ramses will be in prime position to conduct before-and-after surveys to see how Apophis reacts to Earth. By looking for disturbances Earth’s gravitational tidal forces trigger on the asteroid’s surface, Ramses will be able to learn about Apophis’ internal structure, density, porosity and composition, all of which are characteristics that we would need to first understand before considering how best to deflect a similar asteroid were one ever found to be on a collision course with our world.
Besides assisting in protecting Earth, learning about Apophis will give scientists further insights into how similar asteroids formed in the early solar system, and, in the process, how planets (including Earth) formed out of the same material.
One way we already know Earth will affect Apophis is by changing its orbit. Currently, Apophis is categorized as an Aten-type asteroid, which is what we call the class of near-Earth objects that have a shorter orbit around the sun than Earth does. Apophis currently gets as far as 0.92 astronomical units (137.6 million km, or 85.5 million miles) from the sun. However, our planet will give Apophis a gravitational nudge that will enlarge its orbit to 1.1 astronomical units (164.6 million km, or 102 million miles), such that its orbital period becomes longer than Earth’s.
It will then be classed as an Apollo-type asteroid.
Ramses won’t be alone in tracking Apophis. NASA has repurposed their OSIRIS-REx mission, which returned a sample from another near-Earth asteroid, 101955 Bennu, in 2023. However, the spacecraft, renamed OSIRIS-APEX (Apophis Explorer), won’t arrive at the asteroid until April 23, 2029, ten days after the close encounter with Earth. OSIRIS-APEX will initially perform a flyby of Apophis at a distance of about 2,500 miles (4,000 km) from the object, then return in June that year to settle into orbit around Apophis for an 18-month mission.

Furthermore, the European Space Agency still plans on launching its Hera spacecraft in October 2024 to follow-up on the DART mission to the double asteroid Didymos and Dimorphos. DART impacted the latter in a test of kinetic impactor capabilities for potentially changing a hazardous asteroid’s orbit around our planet. Hera will survey the binary asteroid system and observe the crater made by DART’s sacrifice to gain a better understanding of Dimorphos’ structure and composition post-impact, so that we can place the results in context.
The more near-Earth asteroids like Dimorphos and Apophis that we study, the greater that context becomes. Perhaps, one day, the understanding that we have gained from these missions will indeed save our planet.
