Lightning strikes will double in Arctic as climate warms

The uptick in Arctic lightning could cause more wildfires, potentially triggering a feedback loop that releases massive amounts of carbon into the atmosphere.

  • In recent years, researchers have recorded unusually high numbers of lightning strikes and wildfires in Arctic regions.
  • A new study explored how increased lightning could cause a "lightning-fire-vegetation feedback loop" that could accelerate permafrost loss.
  • To better monitor changing conditions in the Arctic, the researchers called for more high-quality lightning monitoring systems.

ESO astronomers observe exoplanet where it rains molten iron

The ESO finds another exoplanet that's definitely not a place for us to go.

  • WASP-76b is an extremely hot planet whose cooler side has a surface temperature of 1,500° C (2732° F).
  • Iron that evaporates in the heat of the planet's day side rains down in molten form on the night side.
  • ESO learned more about the planet's intense climate thanks to its new ESPRESSO (Echelle Spectrograph for Rocky Exoplanet and Stable Spectroscopic Observations) instrument.

We may have to abandon concrete to fight climate change, architectural experts say

The building material seems so ubiquitous — what can we use in its place?

  • Concrete is a surprisingly dangerous contributor of greenhouse gas emissions.
  • For years, architects haven't been concerned with these emissions since concrete buildings last for so long; their carbon footprint is spread out over their entire lifespan.
  • However, as we approach climate "tipping points," the front-loaded cost of concrete construction may be too high.

Icelandic plaque to commemorate first glacier 'killed' by climate change

A grim warning for the future of Iceland's glaciers.

PEXELS - Jay Mantri
  • Icelandic locals and scientists have created a plaque for the melted Okjökull glacier.
  • Due to climate change, the glacier is no more.
  • If this trend persists, by 2200 all of Iceland's glaciers will have melted.

High in the Alps, where it's 'not supposed to melt,' a rare glacial pond has been discovered

It is rare for them to form, nonetheless reach this size.

  • Climbing instructor discovers a glacial "lake" high in the Alps.
  • A glacial meltwater lake this size is usually a rare occurrence.
  • French glaciologists are concerned that climate change could create more dangerous lakes like these in the future.
