Sea level is rising all over the world thanks to the heat-trapping effect of greenhouse-gas emissions, but according to a new study published in the Journal of Coastal Research, the northeastern U.S. and eastern Canada have seen the ocean rise at an accelerating rate in recent decades. Based on readings at 23 tidal gauges stretching along the … Read More
NOAA operates two GOES spacecraft that orbit at a distance of 22,300 miles above the Equator, and another GOES spacecraft orbits in what is known as "orbital storage mode" in case any trouble arises. NOAA also operates the polar operational environmental satellite program satellites, which fly 540 miles above Earth’s surface, circling near the Nort… Read More
If it feels or looks like autumn leaves are taking longer to change color, you’re not imagining things. Over the past 25 years, the onset of autumn has shifted throughout the lower 48 states, with leaves now staying on trees about 10 days longer than they did in the early 1980s. Using satellite-based measurements of the Normalized Difference Veget… Read More
The new and most controversial finding in the report is that the upward trend in weather-related disaster losses is being driven in part by manmade global warming, since previous studies have shown that socioeconomic factors, such as population growth and urban sprawl, are behind this trend. At the same time, however, studies have increasingly fou… Read More
The researchers used both observations and computer simulations to identify long-term climate signals that might help provide predictability for extreme tornado outbreaks. The ocean configuration they zeroed in on is known as “Trans-Niño, since it occurs during the transition phase as an El Niño or a La Niña event begins or comes to an end.… Read More
Controversial U.S. businessman's iron fertilization off the west coast of Canada contravenes two UN conventions.… Read More
One of the major unanswered questions about climate change is whether hurricanes have become more frequent and stronger as the world has warmed up. Until now, there hasn’t been enough evidence to settle the question for sure, but a report just published in Proceedings of the National Academy of Sciences may have changed all that. Using an entirely … Read More
The last below-average September temperature was in 1976, when Gerald Ford was President, and the last below-average month for any month of the year occurred in February 1985, during the Reagan Administration.… Read More
