2018 Global Temp Review: Land & Ocean

At long last, the government is open and the year-end climate reports from NOAA and NASA are out. As expected, 2018 was the fourth-hottest year on record globally, and another near-record year for U.S. weather and climate disasters. All of the years on record that were hotter or more disaster-filled came in the past decade. To bring context to the

Greenhouse Gas Concentrations

Volume II of the Fourth National Climate Assessment (NCA4) is expected to be released soon. Written by more than 300 scientists, this report comes from the congressionally mandated U.S. Global Change Research Program (USGCRP), which was created with the passage of the Global Change Research Act of 1990. Volume I of NCA4, the Climate Science Special

Greenhouse Gas Sources in the U.S.

Rising Global Temperatures and CO2

The average global temperature fluctuates every year. However, when you look at a snapshot of the global temperature trend, it's on the rise - particularly since 1970. The main cause? Carbon dioxide and other greenhouse gas emissions from human activities. There are plenty of factors that influence temperatures in different regions across the

The 10 Hottest Global Years on Record

According to NOAA, 2017 finished as the third-warmest year globally since records began (NASA ranked it second-warmest). This is the warmest year on record without an El Niño in the Pacific Ocean, as neutral conditions existed in the Pacific until La Niña developed in the fall. Even so, the global ocean was still the third warmest on record, highl

10 Hottest Years on Record

Carbon pollution has driven up the global average temperature for more than a century. So perhaps it’s no surprise that the 10 hottest years ever recorded have all occurred since 1998. The hottest year on record is 2016. It broke the record set in 2015, which itself broke the record setting 2014.

The Fall Heat Is On, Globally, Nationally, Locally

Warming fueled by greenhouse gas emissions continues to rewrite the record books: Over the past several weeks, heat records continued to fall at global, national, and local scales. At the largest of those scales, October tied for the third-warmest October on record according to the National Oceanic and Atmospheric Administration (NOAA) global

The March Continues for 2016 to be Record Hot

Global temperatures have begun to retreat from their El Niño-fueled peak earlier in the year, but the excess heat trapped by greenhouse gases is keeping them well above average and 2016 is likely to become the hottest year on record. The National Oceanic and Atmospheric Administration released its temperature data through the end of October on

Second-Warmest October Cements Hottest Year

October was the second hottest on record for the planet, NASA data released Tuesday shows. The month was the latest in a string of record- and near record-warm months that will see 2016 easily take the title of hottest year in the books. While an exceptionally strong El Niño helped to boost temperatures early in the year, most of the excess heat

The Hottest Months on Record Have Something in Common

On Tuesday, the National Oceanic and Atmospheric Administration (NOAA) released its global temperature data for September. It shows that the month was a scant 0.07°F (0.04°C) below September 2015’s record making it the second-warmest September on record. That ends a streak of 16 consecutive record-setting hot months in NOAA’s dataset, a record

September an Exclamation Point on String of Hot Months

2016 is the year where abnormal has become the norm when it comes to the global temperature. New data from NASA shows that yet again, the planet had a record-warm month. September set a record with temperatures 1.6°F (0.91°C) above normal, besting the previous mark set in September 2014. It’s the latest in a run of months — and years — where freak

It’s High Time to Shift Climate Change from Theory to Fact

It happened again. August 2016 was the warmest August on record across the globe. If that news sounds familiar to you, you’re not mistaken. It was, in fact, the sixteenth straight month of record-breaking temperatures, with global average temperature data dating back to 1880. The so-called “Super El Nino”, which lasted from late 2014 through the
