The consequences of global warming are quite evident this year as winter disappeared early and summer kicked in earlier than usual in a number of countries.

The European summer began ten days earlier this April than four decades ago. This climatic shift has occurred between the 1960s and 2000s.

The seasonal clock is now a chaos and there is a possibility of summer to begin 20 days earlier by the end of this century. Researchers said this climatic change is happening due to increasing carbon emissions into the environment.

This situation is not only in Europe. China also faces an early summer, which starts around six days in advance. This change occurred between 1951 and 2000. Even the winters did not stay on as usual and came down to 11 days.

Another country facing serious problems due to global warming is Ireland. According to senior climate adaptation scientist Barry O'Dwyer, the climatic change will change so many aspects of the country including the agriculture and infrastructure.

Work must be done to alter the railway tracks that might buckle in the heat. The changes can also bring extreme summers and extreme winters now on.

But not only humans are affected. Global warming has been affecting many species of birds for years now. For instance, the Canada warbler's damp nesting grounds are drying up due to the heat.

Fish kills are also upsetting many people from certain regions where fishing is a very important part of their livelihood.

Rainfall is also going to show up quite unusually in the summer and winter, affecting even agriculture. Farming cycles are losing track because of the climate changes, thus creating havoc in the food production.
