¿Has oído hablar de los puntos de inflexión? Son cambios repentinos en un sistema que lo obligan a pasar a un nuevo estado.

En una serie especial del NY Times titulada "Una conversación con la ciencia", el profesor Tim Lenton compartió los "puntos de inflexión" climáticos y cómo esta idea puede utilizarse para generar cambios positivos en nuestras sociedades.

Un ejemplo de un punto de inflexión climático es el derretimiento de la capa de hielo de Groenlandia.

¿Sabías que el 56,2% de la población mundial reside en ciudades?

El número de personas que viven en áreas urbanas se ha disparado en los últimos 70 años y continúa haciéndolo. De hecho, para el año 2050, se espera que el porcentaje de personas que viven en pueblos y ciudades alcance el 70%.

Did you know that albatrosses mate for life?

These majestic seabirds spend most of their early lives winging out to sea alone. Yet once they find a mate, they return to land each year to rear chicks and spend time with their lifelong partners.

Sounds pretty romantic, right? Unfortunately, not all relationships are ending well these days.

In a recent Royal Society journal, scientists studying albatrosses have found a disturbing trend. Albatross couples are divorcing more frequently than ever, and worsening climate conditions may be the reason.

When you think of insects, the first word that comes to mind probably won’t be “edible”. How can maggots or locusts be made into a gourmet dish?

Surprisingly, what you may consider a gross pest may sound like a great meal to another.

In Africa, Asia, and the Middle East, bugs such as grasshoppers, Tacoma worms, and mealworms are a common delicacy.

The idea of swapping pork, chicken, or beef for bugs might sound icky, but eating these critters can be beneficial to both yourself and the environment. Let's find out more!

To say the last few months have been crazy in the Pacific Northwest and British Columbia would be an understatement. 

Starting in June, the region experienced record hot temperatures that sparked droughts and uncontrolled wildfires, killing about 600 people. Not long after, it was hit by a wave of intense floods that caused dangerous landslides.

To better understand how our climate is changing and prepare for the future, scientists are turning to climate evidence from the past.

A project funded by the European Commission known as Beyond EPICA (European Project for Ice Coring in Antarctica) is planning to drill into the oldest continuous ice core from Antarctica.

The new project is an extension of an earlier one from 2008 that collected an 800,000-year-old Antarctic ice core. The new expedition hopes to sample an ice core that can provide information from 1.5 million years ago.

Have you thought about the life cycle of a can of soda or a bag of chips?

First, it takes energy to extract the raw materials and transform them into a product. After use, the product is discarded as waste that would most likely end up in landfills.  

This cycle of "take-make-waste" is the traditional way that businesses work and has led to high profit and economic growth. This is called a linear economy.

Did you know that 56.2% of the global population resides in cities?

The number of people living in urban areas has exploded in the past 70 years, and it continues to do so. In fact, by 2050 the percentage of people living in towns and cities is expected to reach 70%!

Each year, on October 31, the United Nations hosts World Cities Day. This year's theme was "Adapting Cities for Climate Resilience" to raise awareness about how changing climate affects cities. Let’s explore the challenges that cities face.

Sabemos por los libros de historia que los pueblos indígenas de los EE. UU. Se vieron obligados a renunciar a sus tierras y trasladarse cuando llegaron los colonos europeos.

Pero, ¿cuánta tierra ha perdido realmente esta gente? La respuesta puede sorprenderte.

Un estudio reciente publicado en la revista Science muestra que la colonización europea, así como la expansión de los Estados Unidos, ha provocado que las comunidades indígenas pierdan casi el 99% de toda su tierra natal.

¿Alguna vez has mirado al cielo y has visto líneas rectas y tenues que te hicieron preguntarte, "¿qué es eso?"

Estas líneas se conocen como "estelas de condensación", abreviatura de senderos de condensación, y se forman a partir de las emisiones de escape de los aviones a reacción.

Hoy sabemos que las estelas de condensación están relacionadas con el calentamiento global.  ¿Por qué las estelas de condensación son dañinas y qué se puede hacer para mitigar sus efectos? Vamos a ver.
