  • Jetstream migrationplugin-autotooltip__plain plugin-autotooltip_bigJetstream migration

    Jet streams are narrow bands of fast (100 > 200 km/h) meandering air currents which flow around the globe, near the tropopause level (9–12 km above sea level), in both hemispheres.

    Their positioning is very significantly important to local weather …
  • Cloud forcingplugin-autotooltip__plain plugin-autotooltip_bigCloud forcing

    Cloud Forcing (a.k.a. Cloud Radiative Forcing (CRF) or Cloud Radiative Effect (CRE)) refers to the complex effects which cloud cover has on the Earth's 'radiation budget' - in other words how much they affect warming by the Sun.

    Clouds can reflect (heat…
  • Tetrahedraneplugin-autotooltip__plain plugin-autotooltip_bigTetrahedrane

    Tetrahedrane is a simple 'proposed' hydrocarbon in the family of 'platonic hydrocarbons'

  • Medicinal drug pollution in waterwaysplugin-autotooltip__plain plugin-autotooltip_bigMedicinal drug pollution in waterways

    "“Despite having known for almost two decades that pharmaceuticals are commonly found in aquatic environments (Kolpin et al. 2002), we are only beginning to understand the potential implications of these synthetic chemicals on aqu…
  • Leaf fenestrationplugin-autotooltip__plain plugin-autotooltip_bigLeaf fenestration

    Several species of plants have leaves which are 'fenestrated' - i.e. have large holes in them (from Latin fenestra, window). Notable examples are the Monstera genus (Araceae) e.g. the Swiss Cheese Plant.

    It's known that the holes form due to programm…
