The year 2023 was by far the warmest in Earths recorded history, and perhaps in the past 100,000 years , shattering the previous record set in 2016 by 0.27C (0.49F). In that year, El Nio added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat.
The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).
I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming. In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change. 2016 ), a reduction of Saharan dust concentration since the 1970s ( Evan et al.
The observed reduction in surface warming trend over the period 1998 to 2012 as compared to the period 1951 to 2012, is due in roughly equal measure to a reduced trend in radiative forcing and a cooling contribution from natural internal variability, which includes a possible redistribution of heat within the ocean ( medium confidence ).
And with gruelling heatwaves becoming more common , the nights can be sweltering, with no cooling breeze to relieve the discomfort. C, in July 2016. C, also set in July 2016. By Stephen Burt. Sleeping at the height of summer can sometimes feel impossible. At least you can trust your senses – nights really are getting hotter.
“Natural gas”, also known as methane gas or fracked fossil gas, is a potent greenhouse gas that pollutes the environment and causes climate change when it is burned and when it escapes into the atmosphere during extraction, production, and transportation. But Enbridge is misleading these people, and trying to lock in more Ontarians to gas.
Therefore, it is hardly surprising that National Oceanic and Atmospheric Administration (NOAA) earlier this month confirmed that July was the warmest month ever measured since records began. It beat a five-year-long record that had stood been measured since 2016.
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
When Ted Flint passed away in 2016, his wife Debby began to explore options to preserve the unique site and its natural resources. Ted and Debby Flint purchased the property in 1986 and continued its stewardship. In 1991, much of the complex was added to the National Register of Historic Places.
Since Fall 2016, David has been an Assistant Professor at the University of Nevada, Reno. This article focused on PFAS remediation but we also have some cool funded efforts to develop instrumentation to improve the speed at which the DoD can conduct site characterization and determine if and how much remediation needs to be done.
A child collects drinking water in Rajasthan, India in 2016. Residents of notoriously polluted New Delhi, where half of the population lacks access to air conditioning, describe soaking in contaminated waters to stay cool. . Such events are becoming more common as Earth’s atmosphere continues to warm.
OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster. Atmospheric concentrations. Climate impact. W/m 2 from elevated CO 2.
Specialists like Pulwarty, who is currently a senior scientist in the physical sciences laboratory at the National Oceanic and Atmospheric Administration, use the word “cascade” to describe the long reach. As of June 21, the Department of Water Resources had received 64 reports of dry wells this month, the most in any month since August 2016.
When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,
