Kansas: Extreme heat wave kills thousands of cows

In the USA massacres of cows. Thousands of cows died in Kansas from an extreme heat wave. Matthew Lara, a spokesman for the Department of Health and the Environment said at least two thousand cattle are due to the high temperatures and humidity until Tuesday, June 14th.

Others speak of more than ten thousand cows killed by this heat wave, which is hitting western Kansas particularly hard. Since last June 11, temperatures have reached 38 ° C to 40 ° C and humidity has gone from 18 to 35 percent.

Dr AJ Tarpoff, a veterinarian working with Kansas State University, explained: "Heat stress doesn't happen all at once. Cattle accumulate heat during the day and, at night, take four to six hours. to dissipate that heat. As long as we have a cooling effect at night, cattle can handle the heat.

The point where we run into problems is where we have two to four consecutive days of minimal night cooling and start the day with the heat load we have accumulated the day before still there. " American cows are in most cases black, which means they have an even greater difficulty in dissipating the accumulated heat.

The dead animals seen in the video are also very fat; this too is a factor that may have contributed to the loss of the entire herd.

Heat waves have become more frequent and intense in recent years due, according to scientists, to current global warming or they would be one of the ways in which such warming would manifest itself at the meteorological level, that is, in the short term.

Often, but not always, the most intense heatwaves are preceded by another mini heatwave, lasting a few days, which acts as an anticipation to the second. In Europe, these summer heatwaves are generally linked to the latitudinal shifts of the African subtropical anticyclone which normally settles in subtropical latitudes, while in other areas of the world it is always the subtropical anticyclones that determine the heatwaves with their displacements.
