However, planetary scientist David Crawford of Sandia National Laboratories in Albuquerque, New Mexico, cautions that his own supercomputer calculations of ocean impacts produce tsunamis up to 10 times smaller than those in Ward and Asphaug's analysis.

Not exact matches

New research, led by the University of Southampton, has questioned the role played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers 66 million years ago.

The paper uses evidence and modeling to explain how the sun - blocking impact from a 50 - year stretch of unusually intense eruptions of four tropical volcanoes caused sufficient cooling to produce a long - lasting shift in the generation and migration of Arctic Ocean sea ice, with substantial consequences for the Northern Hemisphere climate that lasted centuries and left a deep imprint on European history.

Hefty chapters summarize thousands of peer - reviewed studies of the impact of rising levels of carbon dioxide — a greenhouse gas produced during the burning of fossil fuels — on plants and soils, agriculture, forests, wildlife, ocean life, and humankind.

This suggests that the Tambora subsurface temperature and sea level perturbations could last well into the 20th century, interfering with the effects of the devastating Krakatau, Santa Maria, and Katmai eruptions which occurred respectively in 1883, 1902, and 1912, producing a cumulative impact on the deep ocean thermal structure in the 20th century.

Global warming, which may have produced temperatures 10 to 30 degrees Celsius higher than today, would have had a significant impact both on oceans, where about 95 % of lifeforms became extinct, and on land, where almost 75 % of species died out.

Climatologists say that at current rates, atmospheric carbon dioxide levels could reach 550 ppm by mid-century, producing a significant impact on global climate and resulting in increased acification of the world's oceans.

Over the next 3 years the Ocean Colour Climate Change Initiative project aims to: Develop and validate algorithms to meet the Ocean Colour GCOS ECV requirements for consistent, stable, error - characterized global satellite data products from multi-sensor data archives; Produce and validate, within an R&D context, the most complete and consistent possible time series of multi-sensor global satellite data products for climate research and modelling; Optimize the impact of MERIS data on climate data records; Generate complete specifications for an operational production system; Strengthen inter-disciplinary cooperation between international Earth observation, climate research and modelling communities, in pursuit of scientific excellence.

That is obvious because over the past 50 years, the oceans appear to have gained 20 something raised to the 22nd power worth of Joules + / - 14.6 something raised to the 22nd power Joules, which is also assumed to be a huge number within a short time frame though we are not particularly sure what time frame is relevant, even though the impact of that 20 something raised to the 22nd power Joules produced roughly 0.09 C + / - 0.045 C increase in the mean value of the upper 2000 meters of the roughly 3600 meter deep oceans over the past 50 something years based on an imbalance estimate of 0.6Wm - 2 + / -0.4 which replaces the previous 0.9 + / - 0.15 Wm - 2 estimate which had a 95 % confidence level.

# 96 prokaryotes — Quoting from the article:» Anomalously low sea ice during summer exposes darker (i.e., low albedo) ocean water to sunlight, producing strong Arctic warming via direct radiative impacts and anomalous latent and sensible heat fluxes that persist into the winter months.
