Warming is now at levels not seen for 115.000 years. In fact, last month was the third hottest June on record globally, confirming 2017 will almost certainly make a hat-trick of annual climate records, with 2015, 2016 and 2017 being the three hottest years since records began.
As reported by the Noaa (National Oceanic and Atmospheric Administration), the sea-surface temperatures for the last month were 0.82 Celsius degrees above the 20th century average. This temperature was beaten only by June 2015 (0.89C above the 20th century average) and June 2016 (0,92C above the baseline).
According to Nasa data is estimated that 2017 will probably be the second warmest year ever recorded, after 2016.
The warming trend is mainly caused by greenhouse gas emission (the result of burning fossil fuels).
Global warming will continue increasing: current trends suggest the 1.5C barrier would be breached in the 2040s (in the most optimistic way).
