Not all heat is made equal.
Between streets stained
red with the indelible ink
of discrimination,
the clammy embrace
of federal excess
can still be felt.
Microclimates persist as
green gentrification
plasters over the excesses
of historic housing policies,
pacifying those who can
now afford it
with promises of
shaded sycamores and
miniature boating lakes.
Redlines don’t fade, they just
coalesce into stripes –
their bulging contours falling
outside the peripheral vision
of the purposefully blind.
This poem is inspired by recent research, which has found that historical housing disparities in the United States are linked with dangerous climate impacts.
Recent research has shown that extreme heat kills more people in the United States than any other type of hazardous weather, and that this is likely to become even more pronounced in the coming years because of climate change. However, extreme heat does not affect all people equally, as surface temperatures can vary across the different neighbourhoods within a single city by up to 10°C, with many vulnerable communities disproportionately exposed to extreme heat. In this new study, researchers investigated the extent to which historic housing policies, specifically ‘redlining’, have resulted in this disparity.
Beginning in the 1930s, discriminatory housing policies in the United States classified some neighbourhoods as being too hazardous for investment, outlining these areas in red on ‘residential security’ maps, and denying residents in these ‘redlined’ neighbourhoods services ranging from banking and insurance to healthcare and supermarkets. While the practice of redlining was banned in 1968, these areas continue to be predominantly home to lower-income communities and communities of colour. By using satellite data and historic housing records for 108 cities across the United States, this study found that in 94% of cases, formerly redlined neighbourhoods were hotter than all other neighbourhoods in that city, being on average 2.6 °C warmer than non-redlined neighbourhoods. This study therefore suggests that as climate change brings heatwaves of greater intensity and frequency, it is the same historically underserved and discriminated neighbourhoods that will ultimately face the greatest impact.
