March 2017: Earth’s Second Warmest on Record

Our global temperature continued its upward trend last month with March 2017 marking the second warmest March ever recorded on this planet. Only March 2016 was warmer.

According to the state of the climate report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 56.79°F. That is a whopping 1.89°F above the 20th-century average. March was also the 387th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

While heat dominated most of the planet in March, some places were particularly warm, including the United States, Europe, and Russia. For the contiguous US, despite the cool conditions in the northeast, it was the 9th warmest March on NOAA’s books.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. In fact, March 2017 marked the first time a monthly temperature departure from average surpassed 1.8°F (1.0°C) in the absence of an El Niño event.

Year to date, the first quarter of 2017 was the second warmest such period of any year on record. Global temperature records date back to 1880.

Easter 2017: Second Warmest on Record for NYC

The calendar said Easter, but it felt more like the Fourth of July in New York City on Sunday. The temperature in Central Park soared to a sweltering 87°F, which is a staggering 25°F above average.

According to the NWS, this was the second hottest Easter on record for the Big Apple. The warmest was April 18, 1976, when the temperature hit 96°F. Unlike Christmas, Easter falls on a slightly different date every year. It is the first Sunday after the first full moon that occurs after the spring equinox.

While the heat was not ideal for the holiday’s famous chocolate eggs, the city’s parks were filled with people enjoying the warm weather. However, if you are not quite ready for summer, fear not. More spring–like conditions are expected to return this week.

NYC Hits 80°F for the First Time this Year

It felt more like June than April in New York City on Tuesday. Building on the prior day’s spring heat, the temperature in Central Park soared to 80°F, marking the city’s first 80-degree day of the year.

Topping out at 20°F above average, the day was unseasonably warm. However, it was not a record breaker. That honor belongs to April 11, 1955, when the mercury soared to 84°F. On average, the city’s first 80-degree day does not show up until April 26.

Wearing short sleeves and enjoying lunch alfresco, many New Yorkers took full advantage of this summer preview. Some even celebrated the clash of the seasons by ice-skating in shorts at the rink in Rockefeller Center (photo below). More seasonable conditions are expected to return later this week.

Earth Posts Second Warmest February and Winter on Record

Our global temperature continued its upward trend last month with February 2017 marking not only the second warmest February on record but also closing out the planet’s second warmest meteorological winter.

According to the State of the Climate report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for February – over both land and sea surfaces – was 55.66°F, which is 1.76°F above the 20th-century average. Only February 2016 was warmer.

This February also marked the 386th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

The three-month period of December, January, and February – meteorological winter in the northern hemisphere – was also unusually warm. NOAA reports that Earth’s average temperature for the season was 1.60°F above the 20th century average of 53.8°F. That makes it the second warmest winter on record, trailing only the 2015-16 season.

While heat dominated most of the planet this winter, some places were particularly warm, including much of North America and Asia. Here in the contiguous US, it was our sixth warmest winter on record.

Coming on the heels of a five-month long La Niña event, which had a modest cooling effect, these soaring temperatures are largely attributed to the long-term trend of human-caused climate change.

NYC Hits 70° in February for the First Time in Twenty Years

It is only February, but it felt more like May in New York City on Friday. The temperature in Central Park soared to 70°F, which is a whopping 26°F above average.

According to the NWS, this was the first time in twenty years that the city had a reading in the 70s during the month of February. However, it was not a record breaker. That honor belongs to February 24, 1985 when the mercury hit 75°F.

The primary driver of these balmy conditions is a strong Bermuda High off the east coast of the US that is funneling warm southern air into the region.

Many New Yorkers got out to enjoy this early spring preview and described it as “amazing” or “unbelievable”. Personally, it felt a little surreal to see rowboats out in Central Park during a month when sledding and ice-skating are usually the norm.

That said, a chilly change will be in the air later this weekend when temperatures are expected to return to more seasonable levels.

A Spring-like February Weekend in NYC

Between picnics in the park and overflowing crowds at local ice cream shops, it felt more like late April than mid-February in New York City this holiday weekend.

The temperature in Central Park soared to 63°F on Saturday and 65°F on Sunday. Both days missed setting a new record high by only a few degrees. Overnight lows were also unusually mild. According to the NWS, a new record warm minimum temperature was set on Sunday with a reading of 53°F. The previous record of 49°F was established in 1997.

The city’s normal high for this time of year is 43°F.  Its normal low is 30°F.

Any snow that was left over from the storm earlier this month was no match for these spring-like temperatures.  More abnormally warm conditions are expected later this week, so keep that frisbee handy.

January 2017: Earth’s Third Warmest January on Record

Our global temperature continued its upward trend last month with January 2017 marking the third warmest January ever recorded on this planet. Only the Januarys of 2016 and 2007 were warmer.

According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 55.18°F. That is 1.58°F above the 20th-century average.

January was also the 385th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

While heat dominated most of the planet this January, some places were particularly warm, including the eastern half of the United States and most of Canada. For the contiguous US as a whole, it was our 18th warmest January on NOAA’s books.

Coming on the heels of 2016 – Earth’s third consecutive warmest year on record – these soaring temperatures are largely attributed to the long-term trend of human-caused climate change. Whereas El Niño gave global temperatures a boost in the early part of last year, it dissipated in the spring. ENSO-neutral conditions prevailed in January.

A Record Warm February Day in NYC

Walking around New York City on Wednesday, it was difficult to remember that it was still February. The temperature soared to 62°F in Central Park, setting a new record high for the date. The previous record of 61°F had been in place since 1965.

This was the second time this winter that a daily high-temperature record was broken in the Big Apple. The city’s normal high for this time of year is 40°F.

Venturing out without coats and enjoying lunch alfresco, many New Yorkers took full advantage of the unseasonable warmth. These spring-like conditions, however, will be short-lived. The city’s first major snowstorm of the season is expected to hit early Thursday morning. Get ready for weather whiplash!

2016: Earth’s Third Consecutive Warmest Year on Record

It’s official, 2016 was the warmest year ever recorded on this planet.

According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the year – over both land and sea surfaces – was 58.69°F. That is a staggering 1.69°F above the 20th-century average and surpasses the previous annual record that was set just last year. That makes 2016 the third year in a row to break a global temperature record.

As remarkable as this feat is, it does not come as much of a surprise. During the year, eight new global monthly temperature records were set.

A strong El Niño event influenced this record warmth, but it does not tell the whole story as it dissipated in June and was replaced by its cooler counterpart, La Niña, in the autumn. Therefore, the long-term trend of human-caused climate change was also a key factor. NOAA reports that 2016 marked the 40th consecutive year that our annual global temperature was above its long-term norm.

While heat dominated the planet last year, some places were particularly warm. Here in the contiguous US, it was our second warmest year on record.

Looking at the bigger picture, all sixteen years of this century rank among the seventeen warmest ever recorded and five were record breakers (2005, 2010, 2014, 2015, and 2016). As greenhouse gases – the main drivers of global warming – continue to spew into the atmosphere, temperatures will continue to rise and records will likely continue to fall. Global temperature records date back to 1880.

A Look at Why Death Valley is the Hottest, Driest, and Lowest Place in US

Death Valley National Park is famous for being the hottest, driest, and lowest place in the United States. The interesting thing about all these extremes, as I learned during a recent visit, is how they interconnect.

Situated in eastern California near the Nevada border, the park’s topography is known as basin and range. This is where the earth’s crust is rifting apart, creating mountains in some areas and deep basins in others. Death Valley is a long, narrow basin that reaches a depth of 282 feet below sea level. It is also in the rain shadow of four different mountain ranges to the west – the Coastal Range, the Sierra Nevada, the Argus Range, and the Panamint Range.

As storms move inland from the Pacific, they must rise up and over each range. In doing so, they cool and their water vapor condenses into rain or snow that falls on the western side of these mountains. By the time a storm system reaches Death Valley, it has lost most of its moisture. The average annual rainfall in the park, according to NOAA, is just 2.36 inches.

These dry conditions, along with the valley’s below-sea-level elevation, help to produce the park’s famous heat. With cloud free skies and sparse vegetation, a maximum amount of sunlight can reach the ground. The rocks and parched soil absorb the heat and radiate it into the air. The warm air rises but becomes trapped by the steep valley walls. After cooling slightly, it is recycled back toward the valley floor where it is heated even further by atmospheric compression. During the summer months, this process generates hot winds and sizzling temperatures. The average high temperature in the park ranges from 67°F in January to 116°F in July. The hottest temperature ever recorded was 134°F on July 10, 1913 – a world record.

Looking ahead, as the climate changes, the southwestern region of the US is expected to become even hotter and drier. It seems like only a matter of time before Death Valley breaks its own heat record.
