www.mnn.com All it takes is a flash. Lightning strikes the ground, creating temperatures of more than 3,000 degrees. The sand around the lightning strike fuses together, and fulgurite is formed. What are fulgurites? The word – based on the Latin world for thunderbolt – refers to a hollow glass tube formed when lightning strikes soil,
“Within 35 years, even the lowest monthly dips in temperatures will be hotter than we’ve experienced in the past 150
Alan Seltzer, a senior at Columbia University, traveled to New Zealand this past summer to work on field experiments aimed at reconstructing temperatures in the region over the last 20,000 years. His adviser, geochemist Martin Stute, is working closely with colleagues at Lamont-Doherty to understand how the southern hemisphere came out of the last ice
Human activity changes the environment, as last week’s release of a report by the Intergovernmental Panel on Climate Change reminds us. But not all change is bad. One way in which animals and plants respond to warming temperatures, for example, is to move beyond their historical distributions, just as they do when they are transported to new regions by humans. The response of people who
Investigating the early earth faint young sun problem with a general circulation model

The faint young Sun problem, i.e. the contradiction of a reduced solar luminosity by 15–25% during the Archaean and the geological evidence for relatively high surface temperatures that allowed
Fall is coming! Leaves are changing color, temperatures start creeping down, and gardeners will be able to get back outside without the threat of heatstroke. Well, in theory. This is Houston, after all. But despite the fact that it’ll be … Continue reading
Habitable conditions on Earth will be possible for at least another 1.75 billion years – according to astrobiologists at the University of East Anglia.
Findings published today in the journal Astrobiology reveal the habitable lifetime of planet Earth – based on our distance from the sun and temperatures at which it is possible for the planet to have liquid water.
The research team looked

People started warning me about the mosquitoes back in April. It sounded grim. But when I arrived in Finnish Lapland in August, the mozzies had peaked earlier in the season when temperatures were unusually high, and were all dead. This was a fortunate escape: Miska Luoto of the University of Helsinki and his team of
We usually say that the Ice Ages of the Quaternary period are gone, but is it really? It is definitely a subject of “studyworthy” attention. First, I will investigate the ice age climate and compare it to today’s. Second, I will compare today’s climate to temperatures throughout history. Then, I will speak of ice age
It has only taken us 12 years to work ut what every Japanese child knows: in July and August we should swim. It is the only sensible thing to do with temperatures in the 30s and humidity in the 90s. How has it take us so long to work it out?
When I first came to Japan I looked for swimming pools and was surprised to find them uncommon and inconvenient. I sometimes felt a bit sad about it
As the Earth progressively warms with climate change, species that are not able to adapt to shifting temperatures will be propelled towards extinction. Yet according to a new study by the International Union for Conservation of Nature (IUCN) published in research journal Plos One, the majority of species that are most vulnerable to climate change are not given conservation
“Researchers using NASA’s Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice.” Quoted from the NASA press
Twice humans have witnessed the wasting of snow and ice from Peru’s tallest volcano, Nevado Coropuna—In the waning of the last ice age, some 12,000 years ago, and today, as industrial carbon dioxide in the air raises temperatures again. As in the past, Coropuna’s retreating glaciers figure prominently in the lives of people below. In an ongoing project, scientists at Columba University’s Lamont-Doherty Earth Observatory and partner institutions are reconstructing the ebb and flow of ice [...]

Its been a blazing week with temperatures over 100 deg F. Pune this past few days has been as hot as I can ever recall. Time for ice tea and cool stewed mango drinks. Evenings are very warm too. We are giving our rugby kids water breaks every 10 minutes.
But walking through the small lanes near my house are sights like this one:
Summer can be glorious too. And the alphonso mangoes and

I think it’s safe to say that most of us have been experiencing some pretty intense winters. Here in Utah’s Wasatch Front, the valleys received several feet of snow during January and February, and temperatures rarely got above 30 degrees during the day. There was one day in late January
WOOSTER, OHIO–One of the early spring pleasures of a geologist in the Upper Midwest is finally getting outside and scouting the field trips for the semester. Today we had bright sun and temperatures in the 50s (I know — I’m settling) so I went out to plan the late April field trip for my sedimentology
Just returned from a trip to a fly-in, fly-out mine where the temperatures were down to minus forty and fifty. The only consolation for the extreme cold was the company. Here are a few word pictures of some of the people I chatted to. I set them down here as a way to represent the extremes of
The Earth Institute is pleased to present the fourth of the 2012-2013 Sustainable Development Seminar Series titled “Ch-Ch-Ch-Changes: Recent trends in temperatures, extremes and hydroclimate” tomorrow (Wednesday, March 13) from 4:00 pm to 6:00 pm at Columbia University’s Low Library, Faculty Room. Please RSVP online to attend. Distinguished speakers will include: Gavin Schmidt, Deputy Chief,
There’s something so awesome about a heavy snowfall, so transformative – it really inspires me. I went out skiing this morning, and I’ve never seen our house looking more beautiful. The snow is about 11 inches deep so far: It’s a wet, heavy snow. Temperatures are hovering right around 32°F (0°C), so it’s sticking to everything. Our lower driveway: Our road: While I was skiing across the floodplain down by
