Seas dominate global weather patterns and the climate crisis is causing profound and damaging changes Damian Carrington Environment editor @dpcarrington Wed 11 Jan 2023 19.00 AED The world’s oceans were the hottest ever recorded in 2022, demonstrating the profound and pervasive changes that human-caused emissions have made to the planet’s climate. More than 90% of the excess heat trapped by greenhouse gas emissions is absorbed in the oceans. The records, starting in 1958, show an inexorable rise in ocean temperature, with an acceleration in warming after 1990. Sea surface temperatures are a major influence on the world’s weather. Hotter oceans help supercharge extreme weather, leading to more intense hurricanes and typhoons and more moisture in the air, which brings more intense rains and flooding. Warmer water also expands, pushing up sea levels and endangering coastal cities. The temperature of the oceans is far less affected by natural climate variability than the temperature of the atmosphere, making the oceans an undeniable indicator of global heating. Revealed: how climate breakdown is supercharging toll of extreme weather Last year is expected to be the fourth or fifth hottest recorded for surface air temperatures when the final data is collated. During 2022, we saw the third La Niña event in a row, which is the cooler phase of an irregular climate cycle centred on the Pacific that affects global weather patterns. When El Niño returns, global air temperatures will be boosted even higher... https://amp.theguardian.com/environ...-hottest-ever-recorded-in-2022-analysis-shows ______________________________________ Nothing to see here
Yawn. Unheralded Global Ocean 2000-Year Temperature Reconstruction Reveals Embarrassingly Small Modern Changes By Kenneth Richard on 12. October 2020 It didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer than today, and […]
I don't know about the rest of you but I kind of enjoy the warmer weather regardless of the occasional tropical storm. Of course I don't live in trailer park or a flood zone.
The 10 hottest years on record have all come in the last 20 years. The pace of global warming is picking up and you'd have to be a fool not to see it.
No, the pace hasn't increased at all, and it has been COOLING since 2016 when the last big El-Nino faded away. LINK UAH per decade warming rate DROPPED a year ago from .14C/decade to .13C/decade. === Warming rate is declining since 1994. Arctic ice decline rate is zero in last 16 years. Sea level rise rate has been in decline for 10 years. Major Hurricane/Tropical storm rate, duration and strength in slow decline since 1998. The rate of CO2 emissions has almost doubled while warming rate has declined for 18 years now. LINK No Climate Emergency developing at all.
On the plus side, warmer oceans usually mean more rainfall, easier for trees to grow, and both rainfall and cloud cover can help moderate temperatures on land. It can also mean more snow, which is bad for humans but can be good for the environment (if you have more snowpack, rivers will have a supply of water all year, and at northerly parts of the world, if there's enough snow it can last into the summer and reflect sunlight, helping to reduce global temperatures).
More floods washing away crops https://www.abc.net.au/news/2023-01-10/falling-kimberley-water-levels-reveal-enormous/101842544
At least those crops don't need as much irrigation. But this is assuming the rainfall falls during the warm season part of the year. It will depend on the region. For places like California and the U.S. upper Eastern Midwest, it will be more likely to lead to flooding. For other warmer places that get most of their rainfall during the summer, it will benefit them. For example, it will probably benefit agriculture on the east coast of Australia. Flooding is also more likely in areas that typically do not receive consistent rainfall (places without grass or where the grass is brown most of the year). Higher rainfall from warmer ocean temperatures will probably not contribute to the flooding of the Mississippi river as much, because more of that rain falls in the month of May or June, whereas the flooding most commonly happens at the time of melting snow in early April. (Although sometimes the floods can be later in the year, in June or August)
The numbers don't support a mass extinction claim. Gregory Wrightstone: exposing the mass extinction lie 2019 › 05 › 27 › gregory-wrightstone-exposing-the-mass-extinction-lie stunning analysis of these claims by Gregory Wrightstone. This made a big impact at Wednesday’s House ... By Gregory Wrightstone at his website, 13 May 2019. ". . . Below, all 529 species available from the Red List with a known extinction date are shown below in Figure 2 by decade of extinction. This chart reveals quite a different story than that advanced by the new report. Instead of a steady increase in the number and rate of extinctions we find that extinctions peaked in the late 1800s and the early 20th century, followed by a significant decline that continues today. It is thought that this extinction peak coincides with introduction of non-native species, primarily on islands (including Australia). A closer review of the most recent information dating back to 1870 reveals that, instead of a frightening increase, extinctions are actually in a significant decline. What is apparent is that the trend of extinctions is declining rather than increasing, just the opposite of what the new report claims. Also, according to the IPBES report, we can expect 25,000 to 30,000 extinctions per year, yet the average over the last 40 years is about 2 species annually. That means the rate would have to multiply by 12,500 to 15,000 to reach the dizzying heights predicted. Nothing on the horizon is likely to achieve even a small fraction of that. . . . .
You linked to “wood for trees” which has this disclaimer Which is also only UAH6 data NOT a conglomerate of all global temperature recordings and it is unclear whether this data was lower troposphere https://en.wikipedia.org/wiki/UAH_satellite_temperature_dataset But why not use Berkeley Earth https://berkeleyearth.org/global-temperature-report-for-2021/
LOL You didn't counter anything I posted, and YOUR link supports the cooling since 2016 anyway. Try reading your stuff twice before you think of posting an alleged counterpoint.
2022 Data Are In: Pacific Typhoon Trend Continues To Drop, Alarmist Claims Contradicted! By P Gosselin on 13. January 2023 Share this... Pacific typhoons formed and those making landfall in Japan both have seen no rising trend for the past 70 years. Charts by Kirye Now that all the data are in for 2022, the Japan Meteorological Agency (JMA) presents the latest data for Pacific typhoons. Their data go back more than 70 years, to 1951. First we look at the latest data from the Japan Meteorological Agency (JMA) for the number of typhoons formed annually in the Pacific since 1951. Data source: JMA. Contrary to the claims often heard from alarmists that typhoons are getting worse and more frequent, the trend has been clearly downward since the globe has warmed nearly 1°C. This is good news. No crisis here. . . .
