The Government must keep its promise to ban new offshore oil and gas. Drilling harms marine wildlife, causes toxic spills, and won't lower our bills. Add your name to protect our ocean!

🧊 Arctic sea ice slowdown? Ice hasn’t shrunk much since 2005 — but it’s still half the 1980s size. This pause is natural variation, not recovery. The Arctic is warming 4x faster than the global avg. 📉 Loss could soon accelerate fast. 🔗 Read Dr. @jamesgrecian.com's take: tinyurl.com/bdd8wmh6

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between May and August by looking at the decadal average line positions.
