A new phenomenon, urban heat islands in Jaipur indicates that the city has begun to witness the worst of climate change.

This summer, Jaipur’s temperatures are soaring upwards of 40 degree Celsius. Jaipur witnessed its hottest day on April 26 when a temperature of 43.2 degree Celsius was recorded. Of late, at least some parts of the city are beginning to exhibit signs of climate change typical of large cities. With more concrete and asphalt replacing natural vegetation, “urban heat islands” are becoming a reality and Jaipur is a good example of this.

Scientists study 65-million-year-old rainfall trends to predict future.

Rising atmospheric carbon dioxide levels may spark a shift towards wetter winters and drier summers, warns a new study based on evidence from climatic history preserved in 65-million-year-old oyster shells.

Earlier research shows that about that time, in the Cretaceous period, atmospheric carbon dioxide levels were almost thrice the present amount. It was the most intense greenhouse phase in the history of the earth with unusually high temperature and sea levels. There is also some evidence of torrential rainfall and cyclones.
