A little more than 50 million years ago, the appearance of the frozen continent was not as we know it today. If man could travel to the past and travel to Antarctica, surely he would not need to be lined with thermal and waterproof clothing as in current expeditions, since the temperatures would be warm and pleasant. These are the conclusions of a study published in Nature, which reveals that during the Lower Eocene Antarctica was covered with tropical forests.
Yes, at least in cows. Rising temperatures have a major impact on the fertility of these animals, as recently revealed by European research on the effect of climate change on livestock. Heat stress occurs when environmental temperature, radiant energy, humidity, and wind speed create a hotter situation than the animal's thermal neutral zone temperature record.
The sediment strata deposited in two craters in the Arabia Terra region of Mars indicate that climate change could have occurred on the neighboring planet as a result of fluctuations in the orientation of its axis of rotation. This is the conclusion reached by scientists from the European Space Agency (ESA) after analyzing images obtained by the Mars Express probe.
Global warming can be fought by recycling carbon dioxide instead of reducing its emissions, as most of the world political class claim. This is what Ei-ichi Negishi, present in Santiago to participate in the ConCiencia program held this year in Santiago de Compostela, has proposed the Nobel Prize in Chemistry in 2010. For this, as Negishi highlighted in a press conference prior to the conference he will give today Thursday, it is necessary to find the method for catalysis to be "profitable" economically, since, although elements such as silver and gold are known that could be used in the process, their high cost makes their use unfeasible.
In less than 40 years, the planet's temperature will rise between 1.4ºC and 3ºC on average. Nature Geoscience publishes the calculations of an international team of researchers, who warn of the evolution of global warming if greenhouse gas emissions are not mitigated.
Although corals are among the organisms most threatened by rising ocean temperatures, some species may adapt better than others, according to a study published in PLoS ONE.
NASA has made available to the scientific community a map of the height of forests around the world with a spatial resolution of about one kilometer. The image will be a very useful tool to study the effects of climate change on forests and calculate the total carbon accumulated in vegetation globally.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
