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.

Honda To Produce Only Electric Cars By 2040

Japanese carmaker Honda has announced plans to stop the production of petrol- and diesel-powered cars by 2040. In addition, 40% of all cars produced by the company will be emissions-free, either electric or fuel-cell driven, by 2030. The company also plans to introduce electric motorcycles and scooters to the market. At the moment, Honda does not have very many electric vehicles in its production.

Honda has become a partner of American carmaker General Motors and has agreed to use GM batteries in its new electric cars. It also wants to develop driver-assisted software in order to make cars safer and prevent accidents.

Honda is one of many car producers that have promised to make cars emissions-free. Such cars will become more affordable because of cheaper batteries. They will also provide more range. Currently, only a very small part of cars sold worldwide are electric.

Carmakers are reacting to government plans which are to ban all diesel and petrol cars by a certain date in the future.
