Schwefeldioxid ist als Gegenspieler der Treibhausgase offenbar weniger effektiv als bisher angenommen. Aus ihm entstehen in der Luft Sulfat-Aerosolpartikel, die das Sonnenlicht reflektieren und als sogenannte Wolkenkondensationskeime die chemischen Vorgänge in Wolken beeinflussen. Sulfat-Aerosolpartikel helfen also, die Erde zu kühlen. Sie sind deshalb ein wesentlicher Bestandteil vieler Klimamodelle. Wie ein Team um Forscher des Max-Planck-Instituts für Chemie in Mainz nun jedoch herausfand, ist es wahrscheinlich, dass die meisten Modelle bei ihren Vorhersagen den Kühlungseffekt dieser Partikel überschätzt haben. Grund ist ein bisher weitgehend unberücksichtigter Reaktionsweg in den Wolken, den Mineralstaub katalysiert und der die Lebensdauer von Sulfat-Aerosolpartikeln und deren Fähigkeit, Mbclpskwyvo xf oedumtipzsco, yymki hdejnwbitkb.
