A week ago, it looked like it might be a quiet one.
The week of April 5-9 was the hottest one on record for the contiguous U.S., according to a report by the National Oceanic and Atmospheric Administration (NOAA).
But the record did not last.
The year-to-date warmest temperature was on April 14, the previous record-holder, and NOAA says it is now clear that it is still a good thing that the world is experiencing its warmest year ever.
“It is a reminder that the human impact on climate is a global problem and that the U.N. is on track to keep global warming below 2 degrees Celsius,” said Bill Hare, a senior climate scientist at the University of Colorado, Boulder.
“The data are telling us that this is an unusually good year for the U of A.”
NOAA says the record warmth is due in part to a global warming trend that is driven primarily by the burning of fossil fuels.
And while that trend is expected to continue unabated, the heat is being distributed to the rest of the planet as the Earth’s temperature continues to rise.
“We are already seeing the effects of climate change, and we are only just beginning to see them,” Hare said.
“With the human-induced climate change in mind, the NOAA report indicates that we have an opportunity to avoid some of the worst effects of future warming, and that means we should be very careful when looking for ways to limit warming to below 2 C.”
The most extreme weather events that have occurred this year have been associated with increased extreme weather, but it is not the first time such events have occurred.
“That’s a pretty significant shift in the magnitude of the impact,” Hare added.
“There was a major event in the Ussuri-Kosciusko-Manturiz Glacier in Alaska in August, and the same year that there was a massive El Nino event that affected the entire East Coast.”
This year, El Nio has been a big factor, as well.
The heat is affecting the land and ocean, with some areas seeing record-high temperatures in the Northeast and Midwest, according to NOAA.
The agency also noted that this year’s weather events are also helping to spread extreme weather around the globe.
In fact, extreme weather is already affecting the U’s coastlines, with extreme storms and flooding expected to occur over the next few weeks.
“Extreme events have already been occurring in many places around the world, but we know that they are becoming more intense as we approach the peak of this season,” Hare told ABC News.
“This year’s El Ninos and La Nina events are helping to push more heat across the U, but there is still much work to be done.”
For now, Hare said it is too soon to tell what the long-term impacts of the warming trend will be, but he does believe that the longer we wait for a climate solution to come from the United Nations, the worse it will get.
“Climate change is real, it is occurring and it is a serious problem,” Hare explained.
“I don’t know what the longer term effects will be on us, but if the longer-term trends continue, it will be very hard to stop.”
