The outcome of this year’s presidential election could have far-reaching implications for the fate of our planet because the two presumptive candidates, Democrat Hillary Clinton and Republican Donald Trump, have very different ideas about climate change. What will they do about the Paris accord and climate change?
Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.
Given their adaptation to cold climes and their advanced, albeit under-appreciated, skills, how were Neanderthals beaten out by their human counterparts? The answer lies in a combination of culture and genetics that enabled the successful radiation of humans.
We often think of the fight against climate change on a national or international level, but what can we do as a community?
Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially lower.
Maureen Raymo, a marine geologist at Lamont-Doherty Earth Observatory whose name is connected with key theories about how ice ages wax and wane and how sea levels change, has been elected to the National Academy of Sciences, one of the highest honors awarded to scientists in the United States.
“With sea levels on the rise, several island nations are scrambling to stay above water and ensure citizens will have a place to go when the ocean engulfs their homeland. The humanitarian-crisis phase of climate change has officially begun.”
Olivia Owre-Bell, a recent alumna of Columbia’s MPA in Environmental Science and Policy program, attended the Climate Reality Leadership Corps 31st training in the Philippines this March.
Natalie Boelman and colleagues are tagging American robins near Slave Lake, Alberta, Canada, as the birds migrate north to nesting grounds. In a recent blog post for NASA, she put up videos about their work. You can watch some of them below, or go to the blog page at NASA’s Earth Observatory to see and read more.
“Climate change is an extreme example of what happens when you do not have sustainable development. We will not address climate change unless we change the patterns of production and consumption that drove us to this situation in the first place.”
