Earth had its hottest decade on record in 2010s

Scientists at the Met Office Hadley Centre, the University of East Anglia's Climatic Research Unit and the UK National Centre for Atmospheric Science produce the HadCRUT4 dataset, which is used to estimate global temperature. The decade that just ended was by far the hottest ever measured on Earth, capped off by the second-warmest year on record, NASA and the National Oceanic and Atmospheric Administration reported Wednesday, Jan. 15, 2020.

"This is going to be part of what we see every year until we stabilize greenhouse gases" from the burning of coal, oil and gas, Schmidt said.

Australia had its hottest, driest year ever - a precursor to the bushfires. #NASA and @NOAA work together to track temperatures around the world and study how they change from year to year.

NOAA said the average global temperature in 2019 was 58.7 degrees (14.85 C), or just a few hundredths of a degree behind 2016, when the world received extra heat from El Niño.

On a more regional level, this confirmation follows close on the heels of the recent Met Office announcement that the 2010s have been the second warmest of the cardinal decades over the last 100 years of United Kingdom weather records.

Statistical analysis of the data shows that this warming is mainly caused by increased carbon dioxide emissions - as well as other greenhouse gases - produced by human activities like manufacturing, farming, and livestock keeping. The data also show that the past five years were the warmest in the 170-year series. 2019 was also one of the warmest years on record for Europe, including a record-breaking summer heatwave.

The annual global land and ocean temperature has increased at an average rate of +0.13°F (+0.07°C) per decade since 1880; however, since 1981 the average rate of increase is more than twice that rate (+0.32°F / +0.18°C).

A year ago saw the second highest average global temperatures in records dating back to the 19th century, evidence from multiple data sets suggests.

A year ago was the Earth's second hottest since records began, and the world should brace itself for more extreme weather events like the devastating bushfires that have hit much of Australia, according to the World Meteorological Organisation (WMO).

"Unfortunately, we expect to see much extreme weather throughout 2020 and the coming decades, fuelled by record levels of heat-trapping greenhouse gases in the atmosphere", said WMO Secretary-General Petteri Taalas.

Advocacy group 350 Canada, in a tweet, said the need for urgent action to address the climate crisis, including Green New Deal legislation and making those most responsible pay, is clear.

"We are experiencing the impacts of global warming unfolding literally in real time", Noah Diffenbaugh, senior fellow at the Stanford Woods Institute for the Environment said ahead of the release, adding "the last decade in addition to being the warmest decade on record is a decade in which our understanding of climate change has grown in many ways". "2020 is off to a horrifying climate start, and I fear what the rest of the year will bring to our doorsteps". "That is why this decade we make the fossil fuel industry pay for climate justice and fight like hell for a #GreenNewDeal".
