Human health affected by climate change: BBC News Review


A new report on climate change has concluded that rising temperatures are seriously harming human health.

The report from a group of universities and UN agencies says that more people are being affected by heatwaves, a poor diet and the spread of disease.

  1. Huckleberry Finn who comes from Seoul ! says

    I've just come to know that according to you, the phrasal verb 'taking a toll of something' is being used in England by the meaning of paying for some negative, uncomfortable or foolish behaviour, not just paying for a toll when crossing a bridge or passing through a road. Thanks a ton, BBC Learning English! 🙂

    A wide variety of things can be done to protect our environment. One of the things that can be done is to make the existing road vehicles more fuel efficient. Nearly all petrol vehicles that are on the roads today are suitable to have LPG systems installed. LPG is a cleaner and cheaper fuel. Petrol will still be needed to start the engine but then the LPG system will soon activate. The rate of petrol consumption will reduce which will cut emissions and still benefit the environment. Hybrid cars, electric cars and even hydrogen powered cars are all good too.

    According to the Vostok Ice Core Records, CO2 level changes have followed Earth's overall temperature changes at an 800 year lag for the last 800,000 years. That means that our current CO2 levels are the result of Earth's overall temperature 800 years ago. World leaders have convinced their dependents that this works in the reverse order, relatively quickly, and that we are to blame, so that they can tax us out of a false shared guilt in order to be able to afford to "fight" climate change, an unstoppable natural cycle. The following is the source of this information:

    Historical Carbon Dioxide Record from the Vostok Ice Core

    Laboratoire de Glaciologie et de Géophysique de l'Environnement,
    CNRS, BP96,
    38402 Saint Martin d'Heres Cedex, France

    N.I. Barkov
    Arctic and Antarctic Research Institute,
    Beringa Street 38, 199397,
    St. Petersburg, Russia

    Period of Record
    417,160 – 2,342 years BP

    In January 1998, the collaborative ice-drilling project between Russia, the United States, and France at the Russian Vostok station in East Antarctica yielded the deepest ice core ever recovered, reaching a depth of 3,623 m (Petit et al. 1997, 1999). Ice cores are unique with their entrapped air inclusions enabling direct records of past changes in atmospheric trace-gas composition. Preliminary data indicate the Vostok ice-core record extends through four climate cycles, with ice slightly older than 400 kyr (Petit et al. 1997, 1999). Because air bubbles do not close at the surface of the ice sheet but only near the firn-ice transition (that is, at ~90 m below the surface at Vostok), the air extracted from the ice is younger than the surrounding ice (Barnola et al. 1991). Using semiempirical models of densification applied to past Vostok climate conditions, Barnola et al. (1991) reported that the age difference between air and ice may be ~6000 years during the coldest periods instead of ~4000 years, as previously assumed. Ice samples were cut with a bandsaw in a cold room (at about -15°C) as close as possible to the center of the core in order to avoid surface contamination (Barnola et al. 1983). Gas extraction and measurements were performed with the "Grenoble analytical setup," which involved crushing the ice sample (~40 g) under vacuum in a stainless-steel container without melting it, expanding the gas released during the crushing in a pre-evacuated sampling loop, and analyzing the CO2 concentrations by gas chromatography (Barnola et al. 1983). The analytical system, except for the stainless-steel container in which the ice was crushed, was calibrated for each ice sample measurement with a standard mixture of CO2 in nitrogen and oxygen. For further details on the experimental procedures and the dating of the successive ice layers at Vostok, see Barnola et al. (1987, 1991), Lorius et al. (1985), and Petit et al. (1999).

    There is a close correlation between Antarctic temperature and atmospheric concentrations of CO2 (Barnola et al. 1987). The extension of the Vostok CO2 record shows that the main trends of CO2 are similar for each glacial cycle. Major transitions from the lowest to the highest values are associated with glacial-interglacial transitions. During these transitions, the atmospheric concentrations of CO2 rises from 180 to 280-300 ppmv (Petit et al. 1999). The extension of the Vostok CO2 record shows the present-day levels of CO2 are unprecedented during the past 420 kyr. Pre-industrial Holocene levels (~280 ppmv) are found during all interglacials, with the highest values (~300 ppmv) found approximately 323 kyr BP. When the Vostok ice core data were compared with other ice core data (Delmas et al. 1980; Neftel et al. 1982) for the past 30,000 – 40,000 years, good agreement was found between the records: all show low CO2 values [~200 parts per million by volume (ppmv)] during the Last Glacial Maximum and increased atmospheric CO2 concentrations associated with the glacial-Holocene transition. According to Barnola et al. (1991) and Petit et al. (1999) these measurements indicate that, at the beginning of the deglaciations, the CO2 increase either was in phase or lagged by less than ~1000 years with respect to the Antarctic temperature, whereas it clearly lagged behind the temperature at the onset of the glaciations.

    I couldn't listen to BBC in the past and this is the first time I can catch and understand the video 80% . I 'll make the best of it to master English one day. My dream 'll be come true b/c BBC is an indispensable part of my morning routine now.

    While debating climate change, i think there is one thing we have forgotten or overlooked that way back in history, we have stopped doing and never started since. The sumerian tablets state that at some point we decided that clearing the waterways was too great a burden. Now with our sun not setting in its proper place on the horizon and magnetic and true north changing more than we are used to, we simply arent compensating for the path of our water's flow across undeveloped lands. The water flows with the magnetic currents from the magnetic poles. The evidence of this occurring long long ago it topographically evident and needs to be used as a route map. Globally we need to adjust the waters route and this will not only halt many catasrophies from occurring, but provide the work and new farmable land that will keep us from loosing resources. This will also halt the migration of peoples to the large cities that will have no supply line anymore, thereby collapsing the economy and civilization as we know it. This will save us. Thank you.

    There are large numbers of people fleeing from their countries for safety.

    I haven't seen program like this I appreciate u guys

  37. Linh Ngo says

    Many thanks for this great video. By the way, I am a little bit confused. Why did they use plural form for "heatwaves" but singular form for "diet" (a poor diet) in the extract from BBC news bulletin?

    Thank u for helping us with English
