Climate change caused by CO2 emissions already in the atmosphere will shrink global GDP in 2050 by about $38 trillion, or almost a fifth, no matter how aggressively humanity cuts carbon pollution, researchers said Wednesday.
Astronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (104–105 year) Milankovitch cycles. Astronomical grand cycles with periods of millions of years also modulate climate variability but have been detected in relatively few proxy records.
This weekend, while I squeeze into a thick winter wet suit for a cold-water surf in foggy San Francisco — and while my cousin in Phoenix goes rock climbing indoors to escape 115-degree heat — hordes of Californians are smearing pink and yellow zinc oxide on noses, shoving feet into hard plastic ski boots and gliding over to the lifts at Mammoth Mountain for yet another day on the slopes. A reminder: It’s August.
Scientists have delivered a “final warning” on the climate crisis, as rising greenhouse gas emissions push the world to the brink of irrevocable damage that only swift and drastic action can avert.
That’s our finding based on a recent survey designed to better illustrate how people perceive the risks from climate change and their support for government climate actions.
Report into lobbying tactics names ExxonMobil and Chevron as worst, while carmaker Toyota takes third.
US oil giants top list of lobby offenders holding back climate action.
Mobil and Chevron are the world’s most obstructive organisations when it comes to governments setting climate policies, according to research into the “prolific and highly sophisticated” lobbying ploys used by the fossil fuel industry.
Nlimate economics researchers have often underestimated – sometimes badly underestimated – the costs of damages resulting from climate change. Those underestimates occur particularly in scenarios where Earth’s temperature warms beyond the Paris climate target of 1.5 to 2 degrees C (2.7 to 3.6 degrees F).
Imagine spending your whole career working on a question to which you don’t want to know the answer. We know that greenhouse gas emissions can and do warm the planet, but we don’t know one very basic thing: how hot, exactly, is it going to get? The main reason for this, of course, is that human behavior is so hard to predict. How will the people of the late twenty-first century get their energy? Will they need as much as we do, or will they have reconciled themselves to fundamentally different lives?
