University of Colorado Boulder

At the foot of the Rocky Mountains, the University of Colorado Boulder is nationally recognized as one of only 36 AAU public research universities. Established in 1876, CU Boulder is a Tier 1 public research university with five Nobel laureates, nine MacArthur “genius” fellows and is the No. 1 public university recipient of NASA awards. CU Boulder is a leader in many fields, including aerospace engineering, physics and environmental law. The school partners with many notable federal research labs, including the National Center for Atmospheric Research, the National Oceanic and Atmospheric Administration (NOAA) and the National Institute of Standards and Technology (NIST). CU Boulder students thrive academically and athletically, with Buff athletes competing in the NCAA Division I Pac-12 conference.

5 years on, true counts of COVID‑19 deaths remain elusive − and research is hobbled by lack of data

Death data in the US is fragmented, incomplete and inconsistent. The consequences of undercounted deaths and lack of real-time tracking continue to be felt with each new public health crisis.
O Lago Imja, um enorme lago glacial na região do Monte Everest, no Nepal, começou como pequenas lagoas de água de degelo em 1962 e agora contém 90 milhões de metros cúbicos de água, volume que já foi reduzido numa tentativa de proteger as comunidades a jusante. Alton Byers

Derretimento de geleiras em montanhas aumenta risco de inundações catastróficas para milhões de pessoas

Quando o permafrost das montanhas descongela e as geleiras derretem, os lagos glaciais podem se tornar um risco de inundação letal para qualquer pessoa a jusante.
A base da astronomia babilônica foi mantida em um livro chamado MUL.APIN, que significa “A Estrela do Arado”, o nome de uma constelação. Ele registrava as posições das estrelas, quando no ano elas seriam visíveis pela primeira vez, os caminhos do Sol e da Lua, os períodos em que os planetas estariam visíveis no céu noturno e outros conhecimentos astronômicos fundamentais. mikroman6/Moment via Getty Images

Astronomia babilônica foi a primeira grande descoberta científica da Humanidade

A ciência usa observações e testes cuidadosos e organizados para criar teorias que são registradas, transmitidas a outras pessoas e desenvolvidas.
Imja Lake, a glacial lake in the Mount Everest region of Nepal, began as meltwater ponds in 1962 and now contains 90 million cubic meters of water. Its water level was lowered to protect downstream communities. Alton Byers

As mountain glaciers melt, risk of catastrophic flash floods rises for millions

When mountain permafrost thaws and glaciers melt, glacial lakes can become lethal flood risks for anyone downstream.

NOAA’s vast public weather data powers the local forecasts on your phone and TV – a private company alone couldn’t match it

NOAA operates fleets of satellites, sensors on airplanes and ocean-going buoys, as well as radar, providing the data used by weather forecasters nationwide – and freely available to anyone.

Relâmpagos ligam o clima da Terra com o clima do espaço

Os raios podem ser usados para sondar os cinturões de radiação Van Allen da Terra, conectando diretamente o clima terrestre e o clima espacial.

Lightning strikes link weather on Earth and weather in space

Lightning can be used to probe Earth’s dynamic Van Allen radiation belts, directly connecting terrestrial weather and space weather.

How satellites and AI help firefighters battle wildfires today

Fire spotters used to watch with binoculars from forest towers. Now, technology can help forecast fire behavior, but human experience is still essential.

Why Africa’s young scientists should help check the quality of climate change research

Global scientific reports about climate change are largely written and reviewed by older researchers from the global north.

Wildfire smoke’s health risks can linger in homes that escape burning − as Colorado’s Marshall Fire survivors discovered

A series of surveys in the months and years after the devastating blaze near Boulder revealed continuing health concerns in surviving buildings, and tips for how to clean up smoke-damaged homes.

We developed a way to use light to dismantle PFAS ‘forever chemicals’ – long‑lasting environmental pollutants

PFAS are made up of a chain of incredibly strong carbon-fluorine bonds, which make them difficult to break down.
