Five future impacts of climate change

1. Temperatures will reach 1.5C above 1850-1900 levels by 2040 under all emissions scenarios 
2. The Arctic is likely to be practically ice-free in September at least once before 2050 in all scenarios assessed. 
3. There will be an increasing occurrence of some extreme events "unprecedented in the historical record" even warming of 1.5C. 
4. Extreme sea-level events that occurred once a century in the recent past are projected to occur at least annually at more than half of tidal gauge locations by 2100. 
5. There will be likely increases in fire weather in many regions.
