Climate change contrarians have come up with all kinds of explanations to prove that humans aren’t responsible for global warming, ranging from changes in solar activity to natural cycles in Earth’s own wobbly climate system.

One of the increasingly popular reasons given by them was cosmic rays, which contains highly energetic particles from outer space sources that are constantly bombarding our planet.

Since long, scientists have considered this argument to be baseless, and now, a latest study has further focused on this point and has proved it right.

In the Proceedings of the National Academy of Sciences, researchers have reported that changes in amount of cosmic rays hitting Earth could affect temperatures only in the short term, and not in long term.

According to German researchers, many regions in Europe, Russia and the United States have been facing longer heat waves due to weakened summer winds. The researchers said that climate change has been weakening the summer winds that bring in cool ocean air.

Due to that, Europe, Russia and the US have been facing longer heat waves. In 2010, hot weather in Russia devastated crop harvests and had caused wildfires.

Here’s good news for sky gazers as they will be able to get a glimpse of a solar eclipse on Friday, March 20th. As per astronomy experts, solar eclipse occurs when the moon moves directly between the sun and the earth.

Friday’s solar eclipse will darken the skies as the moon is expected to block approximately 86% of the sun’s light.
