PUNE: January this year was something of a paradox in the age of global warming. It was the coldest January since 2012, but this winter was the fourth warmest the last 117 years.

Satellite altimetry has shown that global mean sea level has been rising at a rate of ∼3 ± 0.4 mm/y since 1993. Using the altimeter record coupled with careful consideration of interannual and decadal variability as well as potential instrument errors, we show that this rate is accelerating at 0.084 ± 0.025 mm/y2, which agrees well with climate model projections. If sea level continues to change at this rate and acceleration, sea-level rise by 2100 (∼65 cm) will be more than double the amount if the rate was constant at 3 mm/y.

Johannesburg – Conditioned that ploughing is the sure way to produce crops, Zimbabwean farmer Handrixious Zvomarima surprised himself by trying a different method.

Analyses show that the five warmest years on record all have taken place since 2010

Provisional figures for global average temperatures show last year was the hottest without the influence of warming from El Niño.

Earth's long-term warming trend continued in 2017, government scientists reported on Thursday, with average surface temperatures only slightly below the record heat of the previous year.

This report reviews the trends in average global temperature and the extreme weather events that occurred in 2017. The report finds that the global temperature averaged over the last five years (2013, 2014, 2015, 2016, 2017) has been confirmed as the highest ever on record for any five-year period.

Pune: Even as parts of northern and central India shivered this winter and El Nino was absent, 2017 turned out to be the fourth hottest year ever recorded in India.

2017 was the second-hottest year on record according to Nasa data, and was the hottest year without the short-term warming influence of an El Niño event:

The risk of the El Niño-induced food insecurity in southern Africa in 2016; the recent risk of famine in northern Kenya, Somalia, Ethiopia, and South Sudan; and the recent outbreak of the fall armyworm (FAW) in East and Southern Africa (ESA) all demonstrate that responses are still largely reactive than proactive.
