Climate Change Causes Revival Of Plant Unseen For 60 Million Years

Must read




We are already aware of the impacts of climate change on our planet. The adverse effects of climate change are experienced by one and all on a daily basis and have become a major topic for discussion for the past couple of decades. There have been several presentations, TV programs, conventions, seminars, pop culture, and writing regarding the effects of climate change. 

It is an already established fact that climate change mostly has a negative impact upon the world and these effects have destroyed millions of lives and property over decades. On the other hand, it might come as a surprise to many that climate change may also have brought about a few positive changes all over the globe. 

Although there have been very few and numbered positive impacts, one such instance is an ancient tree. This very old plant was used to be found in the United Kingdom long ago but it could not be found anywhere for the past 60 million years. Scientists have attributed this re-appearance of this ancient tree from the UK mainly to the rising temperature of the earth.

Ancient Plant Re-appears Due To Climate Change 

Climate Change

This ancient disappeared plant is the Cycad plant that was present on earth during the time of dinosaurs. Experts have informed that these used to be commonly found in the UK almost 60 million years ago. According to the researchers, the cycad plant has made a comeback that is mainly considered to be a result of the rising temperature of the planet. 

At the present moment, Cycas revoluta is being cultivated in the Botanic Garden of Ventnor in the Isle of Wight. According to the recent statement of Ventnor, these cycad plants are the very 1st female cone that has arrived from the UK. This cultivation has given us a thrilling opportunity by which we can transfer the pollen and produce seeds in the UK. Moreover, it is 1st time that this is being done. 

This exotic plant is often called the “dinosaur plant” owing to its pre-historic existence. Presently, both female, as well as male cones, are being generated in Britain and botanists have stated that global heating may well be the reason behind this. Cycas revoluta is primarily a primitive tree that had dominated the earth nearly 280 million years ago.

Return Of The Primitive 

Cycads are now believed to have lived in various regions of Britain approximately millions of years ago. The fossil of cycad plants had previously been found in the strata of the Jurassic rock between the Isle of Wight stretching till the Dorset Coast. During the time when this plant was in existence was an ear when the climate of the earth had a very high level of carbon dioxide in a natural manner.

The plant that was growing in Ventnor had first been able to successfully produce one male cone almost 7 years ago. However, recently many various plants had been able to produce both male and female cones that have presented a chance to the botanists to transfer the pollen that will generate more seeds. 

During last summer the heatwave was record-breaking which led to the production of the cycad cones. Furthermore, the winters were mild that helped in the growth of the plant cones. The long-term warming has greatly enabled the return of this primitive plant. These plants are growing out of the gardens for the past 15 years although this was not possible 30 years ago. The natural cycles triggered by climate change have motivated this process.
