Earth’s Axis Shifted Because of Climate Change

Recent studies and satellite data has shown that the Earth’s axis is moving faster, due to climate change and global warming. The axis of our planet is a straight line that goes through the poles. It is not in a fixed position but normally moves slowly due to movements inside the Earth. Scientists do not completely understand how this happens.

New information now shows that the movements of the poles are going on much faster than in previous decades, mainly because of the melting of glaciers and large ice masses. This has led to more water on the surface, which pulls at the poles. The North Pole, for example, is moving slowly towards Russia. Since 1980 the poles have wandered about 4 meters.

In addition, farming has led to more and more groundwater around the world being pumped up from below. This water ends up in rivers and finally in oceans, also contributing to a change in the weight of ocean water.

Scientists say that the change in the Earth’s poles is not enough to affect our daily life, but may lead to a change in the length of daytime by a few milliseconds.

US Promises To Cut Emissions By Half in Next Decade

The United States has promised to reduce greenhouse gas emissions by 50% within the next ten years. In an online meeting of heads of state from the main industrial countries US President Joe Biden said that the United States would aim at achieving zero emissions by the middle of the century.

Biden said that fighting global warming and turning to clean energy would create millions of new jobs. In addition, the United States would produce all of its electricity from clean energy sources by 2035.

The new US president has made climate change an important issue , in contrast to Donald Trump, who pulled out of the Paris climate agreement.

Other countries, including Japan and Canada also promised to reduce emissions.
