Carbon dioxide levels hit landmark at 415 ppm, highest in human history
May 14, 2019

The past five years have been the warmest years since records began in the late 1800s, according to NASA and NOAA.

The temperature rise cannot be explained by natural factors, scientists said. In the past 20 years, the world's temperature has risen about two-thirds of a degree Fahrenheit, the National Oceanic and Atmospheric Administration said.

What is your opinion on these alarming indicators? Is it important for the different countries to start taking measures to stop the damage?

Why this year has been so dangerous for Mount Everest's climbers: Everest has always been extremely dangerous, but this climbing season has had 11 deaths so far, that are not related to one event as it usually is, but to several factors. Mountaineers have suggested difficult weather conditions, a lack of experience and the growing commercialization of expeditions are contributing to the danger.   During the week beginning May 20, crowds of climbers became stuck in a queue (fila) to the summit (cima), above the mountain's highest camp at 8,000 meters. Most people can only spend a matter of minutes at the summit without extra oxygen supplies, and the area where mountaineers have been delayed is known to many as the "death zone." (It causes high altitutes sickness) Alan Arnette, who has climbed Everest four times, explained that Nepal issued a record number of permits to foreigners this year. Because each of them requires a Sherpa guide, there are about 800 pe...

10-minute tornado hits Los Ángeles, Chile

Yesterday, 30th of May, in the middle of the storm that has been raging over the country, a tornado hit the southern city of Los Ángeles. The tornado formed around 18:00 and travelled about 3km in the 10 minutes it lasted, blowing roofs away, breaking windows and even rolling over a truck. The incident left around 6500 homes without electric power, 21 houses with severe damage, and at least 10 without a roof. According to Onemi, 16 people were injured, but none died. Additionally, a watersprout (an event similar to a tornado but formed over water) hit Yungay, Región de Ñuble, damaging 42 houses and injuring 168 people. Tornadoes are an unusual phenomenon in the country, but according to meteorologists it is not as rare as people might think. However, the tornado of yesterday was among the strongest ever recorded, and caused much more damage than previous tornadoes. According to experts the frequency of these rare events has grown recently, and just yesterday two of these were seen in...

Study on twins of the effects of extended space flights

This Thursday, April 11, a study of the effects of long-term space travel was released in the Science Journal. What makes this study special is that the two subjects of the study are twins, Scot Kelly and Mark Kelly. Scott was sent on a mission to the International Space Station from March 2015 to March 2016, while Mark stayed on Earth the whole time. Scientists at NASA had been analyzing data since then, and have come up with very interesting results. First of all, scientists noticed that gene expression in Scott changed while he was in space. This does not mean that his genes actually changed, but rather that different genes were activated during the flight. More concretely, three main changes were observed. First, his gut microbiome changed dramatically during the flight, but returned to normal after coming back. Second, the shape of his eye changed during the flight, which is thought to occur due to the lack of gravity. But most importantly, his telomeres, which are protective st...
