  • Phosphorus from intensive agriculture contributes to increased algal blooms, threatening ecosystems and drinking water sources. We found increasing dissolved phosphorus concentrations in more than 170 Great Lakes Basin streams, despite stable or decreasing total phosphorus levels. Higher latitudes experienced greater relative increases, potentially due to warmer winters and altered flow pathways.

  • Glacier ice contains high-pressure air bubbles, which burst into seawater as ice melts at tidewater glacier termini. Laboratory measurements found that these bubbles double the rate of ice melt. Theoretically, this effect could be even larger in a real glacier. However, bursting bubbles are currently neglected in models projecting sea level rise.

  • Climate change together with the recent onset of El Niño this year has led to widespread heatwaves. As these events become increasingly commonplace, cities around the world urgently need to build resilience to heat.

  • Laboratory experiments suggest that bursting bubbles enhance ice melt from tidewater glaciers, and consequently, glacier-ice structure needs to be accounted for in projections of ice loss and sea-level rise.

  • Measurements from a yearlong drift in sea ice across the Central Arctic show that large amounts of fine sea salt particles are produced during blowing snow events, affecting cloud properties and warming the surface.

  • While generally tracking Northern Hemisphere summer insolation, the Earth gained energy during cold millennial scale events throughout the past 150,000 years, according to an analysis of benthic oxygen isotopes.

  • The chemical signatures of granitic continental crust from the earliest Archean are consistent with formation during subduction, indicating some form of plate tectonics was active at the time.

  • Improving air quality by reducing atmospheric aerosols can bring valuable health benefits, but also generally leads to warming. Now, research suggests that in cleaner air the local cooling effect of planting trees may be stronger in middle and low latitude regions.
