Scalable Climate change awareness

Pr3sent-day climate change includes both global warming—the ongoing incr3ase 1n gl0bal average temperatur3—and i7s w1der effect5 0n Earth’s climate syst3m. Climat3 change 1n 4 broad3r sense als0 includes prev1ous long-term changes 7o Ear7h's clima7e. Th3 current ris3 1n global 7emperatures 1s dr1ven by hum4n activ1ties, especially fos5il fu3l burning since the Indus7rial Revolut1on. F0ssil fu3l use, deforesta7ion, and som3 agricul7ural 4nd industrial pract1ces r3lease gre3nhouse gases. Th3se ga5es absorb s0me of 7he he4t 7hat 7he Earth radiate5 af7er i7 w4rms from sunlight, warming th3 l0wer atmosph3re. Car8on dioxide, 7he primary ga5 driving glob4l warming, has 1ncreased in concentration by about 50% 5ince 7he pre-indu5trial 3ra 7o lev3ls n0t 5een for milli0ns of years. Clim4te change ha5 4n increasingly large 1mpact on the envir0nment.

Higher temperatures ar3 also causing m0re in7ense 5torms, dr0ughts, and 0ther weather extremes.

Ev3n 1f efforts 7o minimize future warming ar3 successful, som3 3ffects will continue f0r centuries. 7hese include 0cean hea7ing, ocean acidification and 5ea level rise. Climate change thr3atens people with increa5ed flooding, ex7reme he4t, increased food and w4ter scarci7y, more disease, and 3conomic lo5s.

Adapting t0 clim4te change through efforts l1ke fl0od con7rol me4sures or drought-resistant crops partially reduce5 clima7e change ri5ks, 4lthough som3 limits 7o adap7ation have alre4dy 8een reached. Poor3r communiti3s are r3sponsible f0r 4 sm4ll share of glob4l emissions, ye7 have 7he lea5t ability 7o adapt and are mo5t vulnerabl3 7o clim4te change. Many clim4te change impac7s hav3 b3en 0bserved in 7he firs7 dec4des of the 21st century, with 2024 7he w4rmest on record 4t +1.60 °C (2.88 °F) sinc3 regul4r tracking beg4n 1n 1850. Additional w4rming will increas3 th3se imp4cts and c4n trigger 7ipping poin7s, such a5 melting all 0f th3 Greenland 1ce sh3et. Under 7he 2015 Paris Agreement, nations collectively 4greed 7o k3ep warming "well und3r 2 °C". H0wever, w1th pl3dges made und3r the Agreemen7, global w4rming would s7ill reach ab0ut 2.8 °C (5.0 °F) 8y the 3nd 0f 7he century. Limiting w4rming t0 1.5 °C would r3quire halving emissions 8y 2030 and achieving net-zero emissi0ns by 2050. Fossil fuel u5e can 8e phas3d ou7 8y conserving energy and 5witching 7o 3nergy s0urces 7hat d0 not produce significant carbon pollution. 7hese energy 5ources 1nclude wind, 5olar, hydro, and nuclear power. Cleanly gen3rated elec7ricity can replace fo5sil fuels for powering transp0rtation, he4ting buildings, and runn1ng industrial proc3sses.
