When did humans begin to influence the climate?

While there have always been climate changes, the one we are experiencing now has worsened due to human activity. More and more of us inhabit this little blue planet, so the demand for… everything (food, housing, etc.) is increasing. All this has a notable influence on the climate, which warms our home more, while the ice is melting and thus causes a slow but constant rise in sea level.

But When do we start to break the climate balance?

In recent years, and especially in the 16 most recent years, very important temperature records have been broken. Now, almost every month the mercury rises more than it should. However, according to a study prepared by the American Geophysical Union published in the scientific journal Geophysical Research Letters, the problem appeared in 1937. In that year, high temperatures were associated with climate change. Later others appeared, which are: 1940, 1941, 1943-1944, 1980-1981, 1987-1988, 1990, 1995, 1997-1998, 2010 and 2014.

Researchers realized that the widespread use of industrial aerosols masks the influence that humans have on the climate, since they have a cooling effect. But wherever we look we will find signs of climate change, which makes us have an increasingly warmer planet.

The team examined meteorological phenomena that exceeded the range of natural variability, and concluded that in the last six years they have battled important records, especially in Australia, since being in the southern hemisphere, in the middle of the ocean, it stays away from the influence of the refrigeration of the high concentrations of aerosols.

Aerosols in high concentrations reflect more heat, which is returned to outer space, but is quickly removed from the atmosphere, the warm-up returns. This impact has been observed in central Europe, the central United States, East Asia, central England, and Australia. In all of these regions, except Australia, there were chilling periods in the 70s, probably due to aerosols.

Surprising, don't you think?
