Managed honey bees have the potential to affect native bee populations when they are introduced to a new area, but a study led by researchers at Penn State suggests that, under certain conditions, the native bees can bounce back if the apiaries are moved away.

The ceasefire agreed between Israel and Hamas makes provisions for the passage of food and humanitarian aid into Gaza. This support is much needed given that Gaza’s agricultural system has been severely damaged over the course of the war.

Scientists have engineered sugarcane and sorghum to take advantage of rising levels of carbon dioxide, allowing these crops to grow bigger.

To achieve this, researchers focused on the enzyme Rubisco. Plants deploy Rubisco to help capture carbon dioxide for use in photosynthesis. But sometimes Rubisco can consume oxygen instead, slowing growth. As humans pump more carbon dioxide into the atmosphere, Rubisco works more efficiently, helping capture more carbon dioxide, which helps plants grow faster.

Explosions roared through the canyons lining the Klamath River earlier this year, signaling a new chapter for the region that hugs the Oregon-California border.

In October, the removal of four hydroelectric dams built on the river was completed – the largest project of its kind in US history.

The superyacht and private jet emissions of the richest people are worsening the climate crisis.

The global working class, who have the lowest emissions, face the worst of this crisis.

Let’s look at the human and environmental cost of polluting private jets and superyachts and how to address their weighty impact... An image of a private jet.

At the most northerly tip of the UK, looking north from the island of Muckle Flugga, Shetland, the cold wind whips up the sea and gannets dive.

While biodiversity loss in the Arctic Ocean may seem like a distant issue, the Shetland Islands lie further north than the Arctic Ocean’s southernmost waters. The Arctic Circle is only 380 miles (610km) north of British waters – the same distance as London to Edinburgh by road.

Across much of the world, planting more trees means more carbon is stored, and global warming is reduced. That’s the thinking behind recent proposals to plant more trees in Alaska, Greenland and Iceland.

But we recently published a paper in the journal Nature Geoscience in which we argue that tree planting is no climate solution at northern high latitudes. In fact, it does more harm than good.

Plastic pollution is everywhere. It’s ruining the health of communities across the world, killing wildlife, fuelling the climate crisis and being dumped in oceans. But change is coming.

Thanks to people like you, governments have now started UN negotiations for a Global Plastics Treaty.

Member states of the UN environment assembly are meeting this week in Busan, South Korea to discuss the details of a global plastics treaty for the fifth, and hopefully final, time. Negotiations can be difficult, monotonous, and often go around in circles. The talks can go on for more than 14 hours a day. Those attending complain of meeting fatigue.

The environmental impact of a ChatGPT search versus a Google search varies significantly due to differences in underlying technologies and computational requirements. Here’s a breakdown:

Energy Usage Per Query
ChatGPT
Estimated Energy Per Query: Around 500–1,000 Wh (watt-hours) per query, depending on model size and server efficiency. This equates to ~200–400 g of CO₂e per query. Google Search
Optimized for Efficiency: Google searches rely on highly optimized search algorithms and infrastructure. Estimated Energy Per Query: Around 0.3–2 Wh per search depending on the complexity and features like personalized results. This is equivalent to ~0.2–1 g of CO₂e per query.

Reasons for the Difference
Model Complexity: ChatGPT involves processing millions of parameters for each query, whereas Google Search retrieves indexed results using pre-processed algorithms. Infrastructure Optimization: Google has highly efficient data centers focused on minimizing energy use, while AI queries like ChatGPT require more raw computing power, particularly for language generation.

Comparative Impact
A ChatGPT query could use up to 500x more energy than a simple Google search. For context: ChatGPT: Equivalent to running an energy-intensive task like streaming a high-definition video for several minutes. Google: Comparable to boiling water for a cup of tea or a few seconds of video streaming.

Perspective
To put 400 g of CO₂e (carbon dioxide equivalent) into perspective, here are some activities and items with comparable carbon footprints:

Everyday Activities
1. Driving a Gasoline Car: About 1.6 kilometers (1 mile) driven in a typical petrol car (~250 g CO₂e per km).
2. Using a Clothes Dryer: Running a clothes dryer for 5–6 minutes emits around 400 g CO₂e.
3. Streaming Video: Streaming a 30-minute HD video on platforms like Netflix (depends on server location and energy source).

Food and Drink
4. A Cheeseburger: Producing one cheeseburger emits ~2.5 kg CO₂e, so 400 g CO₂e is roughly one-sixth of a cheeseburger's footprint.
5. A Cup of Coffee: A latte with milk emits 200–400 g CO₂e, depending on milk type (higher for dairy, lower for plant-based alternatives).

Household Energy
6. Electricity Use: Running a 100-watt light bulb for 4 hours, assuming an average energy grid mix (~100 g CO₂e per kWh).
7. Charging Devices: Fully charging a smartphone 50 times (8 g CO₂e per charge on average).

Other Comparisons
8. Plastic Bag: Manufacturing a plastic grocery bag emits about 50 g CO₂e, so 400 g CO₂e is equivalent to 8 plastic bags.
9. Taking a Flight: Flying 2 kilometers (1.2 miles) emits around 400 g CO₂e per passenger.
