following the hottest March on record
Correction

As written in this global-climate context, this is inaccurate. March 2026 was not the hottest March globally on record.

Full reasoning

In this section, the article is discussing global climate trends, and it says April 2026 came "following the hottest March on record." But official global climate agencies did not report March 2026 as the hottest March globally.

NOAA's National Centers for Environmental Information said March 2026 tied as the second-warmest March on record globally, with only March 2025 warmer. The European Union's Copernicus Climate Change Service likewise said March 2026 was the fourth-warmest March globally.

So, in the context of a paragraph about global warming, calling March 2026 the hottest March on record is incorrect. If the author meant a narrower geography, such as the contiguous United States, the sentence should have specified that.

the [Russian invasion of Ukraine](/wiki/Russian_invasion_of_Ukraine "Russian invasion of Ukraine") that started the [Russo-Ukrainian War](/wiki/Russo-Ukrainian_War "Russo-Ukrainian War")
Correction

This gets the chronology wrong. The 2022 Russian invasion did not start the Russo-Ukrainian War; the war began in 2014 with Russia’s seizure of Crimea and conflict in the Donbas.

Full reasoning

The page says the Russian invasion of Ukraine "started the Russo-Ukrainian War." That is inaccurate.

Authoritative timelines place the start of the Russo-Ukrainian war in 2014, when Russia seized Crimea and fighting began in eastern Ukraine. The February 2022 full-scale invasion was a major escalation of that existing war, not its start.

The Council on Foreign Relations' Global Conflict Tracker says armed conflict in eastern Ukraine erupted in early 2014 following Russia's annexation of Crimea. A separate CFR backgrounder likewise says Ukraine became a battleground in 2014 when Russia annexed Crimea and backed separatists in the Donbas, and then notes that in February 2022 Russia embarked on a full-scale invasion.

So the article's wording is chronologically wrong: 2022 did not start the Russo-Ukrainian War.
