Over the last 7,000 years humans have mined more than 700 million tonnes copper. The metals requirements of a net zero energy transition, the world will need to produce another 700 million tonnes of copper over the next 22 years.
Two new studies show that the Earth’s climate is far more complex than often acknowledged, reminding us of the importance of pragmatic energy and climate policies.
Warum es alle hunderttausend Jahre zu einer Eiszeit kommt, konnte bisher nicht komplett erklärt werden. Nun hat ein internationales Forscherteam mit Schweizer Beteiligung die Faktoren identifiziert: Neben der Sonne spielt die Wechselwirkung von Klima und Gletschern eine Rolle.
One of the most pervasive misunderstandings of climate is the belief that any long-term trend in a measured climate variable indicates a change in climate, as defined by the IPCC. In practice, “long-term” is often defined to be only a few decades worth of observations.
Carbon dioxide is indeed the ‘stuff of life’, underpinning photosynthesis, boosting plant growth, enhancing agricultural yields, and enabling practical applications in industry.
Climate scenarios are ridiculously opaque, as if they are designed not to be understood by intelligent people outside the small community of scholars who invent these scenarios. More people should understand how the sausage is made.
Imagine if Republicans gave the Trump Administration tens of billions of dollars to dole out to right-wing groups to sprinkle around to favored businesses. That’s what Democrats did in the Inflation Reduction Act (IRA).
When it comes to extreme weather, cyclones are top of my list. The most extreme cyclone to hit Queensland, Tropical Cyclone Mahina, was arguably the world’s most intense with a central pressure recorded at 880 hectopascals, a 12-metre storm surge, and 300 kilometre per hour winds.
Lapses of scientific integrity in climate science have become normalized. I no longer expect the community to care about obvious and egregious problems in climate science, even when documented in the peer reviewed literature.
While climate might be playing a minor role, by far the greatest factor affecting how much damage results from a fire is the fuel available to it. Have you cleared the brush and other vegetation or not? Also, there’s the infrastructure that you’ve built.
Als grobe Faustregel kann man sagen: Immer wenn die globale Temperatur höher wird, regnet es mehr und die Wüsten werden grün. Und wird es wieder kühler, nehmen die Niederschläge ab und dann breiten sich die Wüsten aus.
Vor kurzem berichteten die Medien aufgeregt darüber, dass laut einer neuen niederländischen Studie der Golfstrom versiegen könnte. Das würde in Europa zu einer verheerenden Abkühlung führen.
