Antarctica Logs ‘Record-Smashing’ Low for Sea Ice, Says NASA

The bad news keeps coming as scientists monitor the levels of Arctic and Antarctic sea ice.

NASA may be famous for its space exploits, but it’s just as concerned with what’s happening on our own planet as it is with what’s going on out yonder. Researchers from NASA and the National Snow and Ice Data Center are tracking sea ice levels on both ends of the globe. A report released this week shows some grim data.

Satellite observations show that Arctic sea ice most likely reached its annual minimum extent on Sept. 19, logging the sixth-lowest year based on records dating back to 1979. The news from the other pole was even more bleak.

«Antarctic sea ice reached its lowest maximum extent on record on Sept. 10 at a time when the ice cover should have been growing at a much faster pace during the darkest and coldest months,» said NASA in a statement. In short, both regions are lacking ice.

Sea ice is disappearing in the face of a warming world. Loss of sea ice affects the people who live in the Arctic as well as the animals and ecosystems at the polar regions. But it also plays a role in the global climate. Read a deep dive on the climate consequences of a «sea ice free» Arctic.

«While bright sea ice reflects most of the sun’s energy back to space, open ocean water absorbs 90% of it,» said NASA. «With greater areas of the ocean exposed to solar energy, more heat can be absorbed, which warms the ocean waters and further delays sea ice growth.»

Satellite data collected between March and September shows that Arctic ice cover shrank from 5.64 million square miles (14.62 million square kilometers) to 1.63 million square miles (4.23 million square kilometers). To put that in perspective, NASA said the lost sea ice could cover the entire continental US. Research points to a long-term decline in Arctic sea ice, with spring melting starting earlier and autumn freeze-up starting later. The ice has also become thinner over time.

NASA released a video with a visualization of the sea ice changes:

In Antarctica, satellite data shows that sea ice reached its lowest winter maximum extent on Sept. 10 with a coverage area of 6.5 million square miles (16.96 million square kilometers). That’s 398,000 square miles (1.03 million square kilometers) less than the previous record low, set in 1986. «It’s a record-smashing sea ice low in the Antarctic,» said NSIDC scientistWalt Meier.

Top-down view of Antarctica in white indicates the extent of sea ice on Sept. 10, 2023, the lowest maximum on satellite record.

NASA called out some potential factors for the lack of Antarctic sea ice, including warming ocean temperatures and the recurring natural weather pattern of El Niño. El Niño delivers higher than normal surface temperatures in parts of the Pacific Ocean. Earlier this month, NASA declared summer 2023 as the hottest on record, pointing to climate change and El Niño as culprits.

Human-caused climate change is fueled by greenhouse gas emissions. The Center for Climate and Energy Solutions traces the majority of these emissions — largely from the burning of fossil fuels for energy — to China, the US and the European Union. The highest per capita emissions come from the US and Russia.

The NSIDC notes that this year’s Antarctic and Arctic sea ice numbers are still preliminary and may be adjusted based on continued observations. Researchers are working on a full analysis while comparing this year’s data with historical records.

What’s key is this likely isn’t an anomaly. Meier said the Arctic changes represent a «fundamental, decades-long response to warming temperatures.»

Google’s New AI Features Are Trying to Make Data Entry a Thing of the Past

More Gemini AI features will come to Google Docs, Sheets and Slides.

The latest batch of Google updates to its workspace tools highlights AI’s promise to automate mundanity in the workplace. Google Docs, Slides, Sheets and Drive all have new AI-powered features, the company announced Tuesday. The one thing all these updates have in common? Gemini is using your files, emails and chats to give you relevant information, not random answers gleaned from the web.

These updates come as AI is playing a bigger role in our work lives, for better or worse. Agentic tools like Claude Cowork and coding assistants like Anthropic’s Claude Code and OpenAI’s Codex are more capable than chatbots and able to handle tasks announced independently. AI tools are also becoming more customized, with Google’s personalized intelligence rolling out across its platforms to help refine AI outputs to things that are relevant and useful for you. Google continues that trend with this new batch of Workspace updates.

New Gemini AI features in Google Workspace apps will cite their sources after each query. For example, if you ask Gemini in Google Docs to fill out an itinerary template, it will pull the information from your email, chats and files. The «sources» tab in the Gemini side panel will show you where it found the information it used, like your flight confirmation email and chats discussing dinner plans. Seeing where Gemini pulled its answers from is also how you’ll double-check Gemini’s work.

The most impressive new features are in Sheets, where AI can fill in the holes in your spreadsheets. You can describe what you want the AI to do with a simple prompt and avoid writing an exact formula. You can click on an empty cell, select the pop-up that says «Drag to fill with Gemini,» then highlight the cells you want Gemini to fill in. That deploys an AI agent to search the web to fill each cell with the necessary information.

For example, if you have a spreadsheet of the contact info for local companies, you can have Gemini search the web to fill in a the location, CEO and other publicly available information of each company. The tool aims to dramatically reduce the time needed for manual data entry. Gemini can also summarize, categorize and create charts with prompts alone.

You can also chat with Gemini in Sheets and have it scour your raw data to make custom reports and charts. No need for pivot tables if they confound you as much as they baffle me. One of the biggest uses of AI at work is helping create presentations.

In Google Slides, you can now tell Gemini in natural language what you want to appear on a slide, and it will create it, matching the style of your existing slides. You can also ask Gemini to edit your slides if you don’t want to waste time painstakingly moving design elements around the slide. The AI should fill the slides with relevant information based on your instructions and the work files it has access to, so you shouldn’t need to replace a bunch of filler text.

If you use Docs, Sheets and Slides through the Workspace account of your company, then you won’t be able to turn off AI features individually. The managing company is in control of AI access for users. Personal users can tweak their settings to limit Gemini. The new features are rolling out in beta now, in English only, to Google AI Ultra and Pro subscribers in the US, as well as some Google Workspace customers who are part of the Gemini Alpha testing program.

Nintendo Switches Lanes, Sues US Over Tariffs

Mario wants his money back.

Tariffs implemented by President Donald Trump were struck down by the Supreme Court last month. Companies that were subjected to those fees, such as FedEx and Dollar General, have since sued the federal government, and Nintendo wants a piece of the action.

Nintendo filed a lawsuit against the federal government in the US Court of International Trade on Friday, as first spotted by Aftermath. The complaint seeks refunds of tariffs Nintendo paid, plus interest, and asks the court to declare the tariffs unlawful and stop the government from collecting them going forward.

«Since February 1, 2025, President Trump has executed the unlawful Executive Orders, imposing tariffs on imports from a vast swath of countries,» Nintendo said in the complaint.

When reached for comment, Nintendo of America confirmed the lawsuit.

«We can confirm that we filed a request. We have nothing else to share on this topic,» Nintendo of America said in an emailed statement on Friday, March 6.

It’s unclear how much Nintendo paid in tariffs, and it did not state an amount in the lawsuit. While the Switch 2 was priced at $450 when it launched last year, and has stayed at that amount, Nintendo did increase the price of the original Switch and accessories for both consoles. Microsoft and Sony also increased the prices of their hardware and accessories last year due to tariffs.

The White House didn’t immediately respond to a request for comment.

On Feb. 20, the Supreme Court ruled by a vote of 6 to 3 that the sweeping tariffs Trump instituted last year exceeded his executive powers. Following the ruling, on the same day, Trump announced a new set of tariffs of 10% on imported goods that would last for 150 days, starting Feb. 24.

The decision on what to do with the collected tariffs — a reported $166 billion — has been left to the US Court of International Trade. Judge Richard Eaton told the US Customs and Border Protection on Wednesday, March 4, to refund the importers that were forced to pay tariffs, which is more than 330,000. On Friday, the CBP said it couldn’t easily issue tariff refunds because its system requires duties to be recalculated and refunds processed entry by entry. This process would involve tens of millions of transactions. The agency said it’s updating its systems and could start providing refunds by late April.
