Ripoti iliyotolewa na Shirika la Hali ya Hewa Duniani (WMO) imesema Matukio kama joto kali na mafuriko makubwa sasa ni hali ya kawaida.
Utafiti umebaini miaka saba iliyopita ukiwemo wa 2021 ina uwezekano wa kuwa joto zaidi kwani viwango vya gesi chafu zilifikia viwango vya juu.
Prof. Petteri Taalas kutoka WMO amesema kuna ushahidi wa kisayansi mabadiliko ya Hali ya Hewa yanasababishwa na binadamu.

Extreme weather events - including powerful heat waves and devastating floods - are now the new normal, says the World Meteorological Organisation.
The State of the Climate report for 2021 highlights a world that is "changing before our eyes."
The 20-year temperature average from 2002 is on course to exceed 1C above pre-industrial levels for the first time.
And global sea levels rose to a new high in 2021, according to the study.
These latest figures for 2021 are being released early by the WMO to coincide with the start of the UN climate conference in Glasgow known as COP26.
The State of the Climate report provides a snapshot of climate indicators including temperatures, extreme weather events, sea level rises and ocean conditions.
The study finds that the past seven years including this one are likely to be the warmest on record as greenhouse gases reached record concentrations in the atmosphere.
The accompanying rise in temperatures is propelling the planet into "uncharted territory" says the report, with increasing impacts across the planet.
"Extreme events are the new norm," said WMO's Prof Petteri Taalas. "There is mounting scientific evidence that some of these bear the footprint of human-induced climate change."
Prof Taalas detailed some of the extreme events that have been experienced around the world this year.

- It rained - rather than snowed - for the first time on record at the peak of the Greenland ice sheet
- A heat wave in Canada and adjacent parts of the USA pushed temperatures to nearly 50C in a village in British Columbia
- Death Valley, California reached 54.4C during one of multiple heat waves in the south-western USA
- Months' worth of rainfall fell in the space of hours in an area of China
- Parts of Europe saw severe flooding, leading to dozens of casualties and billions in economic losses
- A second successive year of drought in sub-tropical South America reduced the flow of river basins and hit agriculture, transport and energy production
