Data shows the year was also one of the hottest three ever recorded, with scientists warning that the ‘climate tide is rising fast’

January 18, 2018 — 2017 was the hottest year since global records began that was not given an additional boost by the natural climate cycle El Niño, according to new data. Even without an El Niño, the year was still exceptionally hot, being one of the top three ever recorded. Continue reading 2017 was the hottest year on record without El Niño boost

Scientists have presented a new, narrower estimate of the “climate sensitivity” – a measure of how much the climate could warm in response to the release of greenhouse gases

January 17, 2018 — The latest assessment report from the Intergovernmental Panel on Climate Change (IPCC) estimates that climate sensitivity is close to 3°C, with a “likely” range of 1.5 to 4.5°C. Continue reading New study ‘reduces uncertainty’ for climate sensitivity

2017 was the hottest year on record without an El Niño, thanks to global warming

Climate scientists predicted the rapid rise in global surface temperatures that we’re now seeing

January 3, 2018 — 2017 was the second-hottest year on record according to Nasa data, and was the hottest year without the short-term warming influence of an El Niño event: Continue reading 2017 was the hottest year on record without an El Niño, thanks to global warming

2017 set to be hottest non-El Niño year, says UN

2017 is on track to be the hottest year on record
2017 is on track to be the hottest year on record except for two warmed by El Nino phenomena, says the UN’s World Meteorological Organization

The UN’s World Meteorological Organization says some 30 percent of the world’s population now experience ‘extreme hot temperatures’ for at least several days each year

BONN, Germany (Nov. 6, 2017) — 2017 is on track to be the hottest year on record except for two warmed by El Niño phenomena, the UN’s World Meteorological Organization said Monday, November 6. Continue reading 2017 set to be hottest non-El Niño year, says UN

Unprecedented Hurricane Season Sees Widespread Damage

This hurricane season has broken multiple records already

September 22, 2017 — On top of powerful winds and flooding, there was darkness. It came when the entire island of Puerto Rico lost power after Hurricane Maria’s onslaught Wednesday. The category 4 storm’s winds ripped through Puerto Rico starting around 7 a.m. Eastern time that Continue reading Unprecedented Hurricane Season Sees Widespread Damage

Study finds human influence in the Amazon’s third 1-in-100 year drought since 2005

Deforestation and climate change appear to be amplifying droughts in the Amazon

August 3, 2017 — If you are like me, you picture the Amazon region as an ever lush, wet, tropical region filled with numerous plant and animal species. Who would imagine the Amazon experiencing Continue reading Study finds human influence in the Amazon’s third 1-in-100 year drought since 2005

Extreme El Niño events more frequent even if warming limited to 1.5C – report

Modelling suggests Australia would face more frequent drought-inducing weather events beyond any climate stabilisation

July 25, 2017 — Extreme El Niño events that can cause crippling drought in Australia are likely to be far more frequent even if the world pulls off mission improbable and limits global warming to 1.5°C. Continue reading Extreme El Niño events more frequent even if warming limited to 1.5C – report

‘Extreme’ El Niños to double in frequency under 1.5C of warming, study says

The El Niño event of 2015-16 was one of the strongest on record, bringing flooding to much of South America, southern US and East Africa, and severe drought to Australia and southeast Asia

July 24, 2017 — Now a new study, published in Nature Climate Change, suggests that similar “extreme” El Niño events could become more frequent as global temperatures rise. Continue reading ‘Extreme’ El Niños to double in frequency under 1.5C of warming, study says

Third-hottest June puts 2017 on track to make hat-trick of hottest years

June 2017 was beaten only by June in 2015 and 2016, leaving experts with little hope for limiting warming to 1.5°C or even 2°C

July 19, 2017 — Last month was the third-hottest June on record globally, temperature data suggest, 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. Continue reading Third-hottest June puts 2017 on track to make hat-trick of hottest years

Study: Why troposphere warming differs between models and satellite data

The most common measure of global temperature rise is here on the Earth’s surface, but scientists also gather data on how temperatures in the atmosphere high above us are changing

June 21, 2017 — Of particular interest is the troposphere – the lowest layer of the atmosphere where almost all of our weather occurs. To track temperatures, scientists use satellites, which have been providing data since they were first launched in the late 1970s.
