Summer Could Last Six Months Because Of Climate Change
Climate change has strongly impacted many aspects of life on the earth in recent years: more frequent floods, higher temperatures, among other phenomena. If we don't act to mitigate heating and greenhouse emission emissions, scientists estimate that by 2100 the summer within the hemisphere could last up to 6 months. This consistent with a study published within the journal Geophysical Research Letters, by analyzing the changes within the duration of the seasons within the hemisphere between 1952 and 2011.
According to the study, within the 1950s the duration of the four seasons within the hemisphere reached a predictable and fairly uniform pattern. However, this has ceased to be the case with global climate change, and, consistent with the researchers’ analysis, summer increased from 78 to 95 days between 1952 and 2011. Winter consequently decreased from 76 to 73 days, while that spring and fall also contracted from 124 to 115 days and from 87 to 82 days.
As a result of these changes, spring and summer within the hemisphere now start earlier, and fall and winter start late. These changes in seasonal cycles were recorded with greater intensity within the Mediterranean region and on the Tibetan plateau. If heating trends continue with no intervention to mitigate them, the researchers predict that by 2100, winter will last but two months, and therefore the transitional seasons of spring and fall are going to be further shortened.

These changes within the duration of the seasons would have several negative effects, several of which are already starting to be felt. Among them, the researchers mention changes within the migration patterns of birds and within the flowering season of plants. this might cause mismatches between animals and their food sources, also as havoc on agriculture and a rise within the length of pollen seasons, causing more allergies.
Regarding the latter, an investigation published within the Proceedings of the National Academy of Sciences, pollen seasons currently begin 20 days earlier. additionally, these seasons are now 10 days longer and present 21% more pollen than in 1990. This was identified supported data, between 1990 and 2018, from pollen counting stations within us and Canada. the info suggests heating is driving pollen production earlier within the year.
About the havoc on agriculture that global climate change and therefore the change within the cycle of the seasons could cause, some crops are going to be more vulnerable to this phenomenon. for instance, the Rainforest Alliance organization predicts a drop of between 65% and 100% within the number of regions suitable for growing coffee in Africa, thanks to global climate change. Other crops in peril are wheat, peaches, cocoa.
To prevent these consequences and havoc, governments, industries, and international organizations must work together to realize zero carbon emissions goals. Otherwise, humanity could face many problems stemming from global climate change, additionally increasing the length of summer to 6 months within the hemisphere by 2100.
