"It's just astonishingly big and it's a reminder of how much risk we're at from sea level rise." "Antarctica has historically been quite a small contributor to sea level rise, but it is growing, and it is taking up a bigger and bigger share of the sea level rise that we see every year," he added. "So, it's a symbol of the growing dominance of Antarctica in the sea level rise equation." This temperature threshold is widely recognized as crucial because so-called tipping points become more likely beyond this level. Tipping points are thresholds at which small changes can lead to dramatic shifts in Earth's entire life support system.

The sun is becoming more active and may reach peak activity sooner than expected. We're currently approaching solar maximum, when the sun reaches peak activity, which experts have previously predicted should happen in 2025. NASAFor example, already this year a powerful solar flare caused widespread radio blackouts that disrupted high-frequency radio signals in North America, Central America, and South America. In the past, powerful solar storms have surged the Quebec power grid, causing blackouts that lasted up to eight hours. Why experts think solar maximum will hit soonWhen the sun's magnetic field is weak, its surface gets a lot more interesting to look at.
